THE ROLE OF THE INTERNATIONAL COURT OF JUSTICE IN
RESOLVING INTERSTATE DISPUTES
I. History and Establishment
1.1 Origins of international dispute resolution
Presence of international dispute can be traced back to centuries it was in the form of arbitration
which later becomes more formalized. Some of the earliest are the Jay Treaty of November 19,
1794 between the United States of America and Great Britain embracing mixed commission for
its solution (Cançado Trindade, 2019). The two Hague Peace Conferences of 1899 and 1907
formed essential proportions; it was in these conferences that the Permanent Court of Arbitration
was introduced for the first time and the avenues for the future formation of other more complex
judicial systems on the international level were being prepared. During the modern period, the
development of international dispute system can be described by the formation of several
institutions and legal instruments aimed at regulation of relations between the states. The League
of Nations created after the First World War added a Permanent Court of International Justice
(PCIJ) in 1922 to address a number of different issues until the organization’s abolishment in
1946 (Hudson, 1943). The PCIJ’s mantle was taken over by the International Court of Justice
which was created under the United Nations Charter in 1945. The ICJ has since then developed
into the principal judicial organ of the United Nations dealing with numerous aspects of
international law (Rosenne, 2007). The aftermath of post – World War II nevertheless, created
specialized means of resolving disputes in various areas of activities like trade and human rights.
Those agreements which were General Agreement on Tariffs and Trade (GATT), widely the
World Trade Organization (WTO) established o comprehensive system for settling trade disputes
among its member states (Petersmann, 1997). Regional systems such as the European human
rights system and the American human rights system have been quite active especially through
institutions such as the European Court of Human Rights and Inter-American Court of Human
Rights that have determined human rights violations and established jurisdictional precedents
(Mowbray, 2012). Additionally, investment disputes have been resolved under several organs
including the International Centre for Settlement of Investment Disputes (ICSID) set up by the
World bank in 1966. It thus offers arbitration and also conciliation services for international
investment dispute that signify the increase in investors’ influence on the world economy. These
developments moreover point to the process of institutionalization within the framework of the
slow evolution of International Relations, which are progressively depending on reliable
structures that can hence provide efficient legal responsibility and also regulate conflicts in a
non-violent manner. Such continually evolving systems underpin the action of the international
community and the adherence to the principles of the rule of law and international cooperation.

1.2 Creation of the ICJ
The I. C. J was created in 1945 by the charter of the United Nations with a view of timely
settling all international disputes. Its formation was as a result of the shortcomings of League of
Nations or rather international system of resolving conflicts in an eve of the Second World War.
The procedures followed by the ICJ are laid down in the Statute that was prepared as a model of
the Statute of the PCIJ, a predecessor to the present court (Crawford, 2023). The ICJ is the main
judicial body of the UN it principles and explains legal disputes of a contentious nature between
states or concerning the legal interpretations of international organizations and also gives out
advisory opinions on legal matters in respect of which reference is made to it by any other
United Nations body or organ authorized to make such a reference (Rosenne, 2007). Its
formation was in part associated with the formation of a more stable, predictable and orderly
post-WW I international environment elaborated in response to the lessons garnered from the
tumultuous interwar period and the wars that result in the need for a solid and efficient legal
regime of peace and cooperation. The ICJ thereby works under an extensive Charter that spells
out its authority, processes, as well as tasks. The Statute also borrows features from the
Permanent Court of International Justice, particularly the stake point that has reassured the
specific permanency of international law (Crawford, 2023). Some of the matters to do with
which the ICJ was constituted include territorial disputes, maritime boundaries, diplomatic
immunity, as well as international treaties’ breaches (Shaw, 2017). The Court has therefore
actually assumed tremendous importance in the formulation of the international law through
delivery of hallmark judgments. Some of these works are Corfu Channel case which dealt on
state responsibility and advisory opinion on the legality of threat or use of nuclear weapons
which involved issues of international humanitarian law. Besides its judicial work, the ICJ
furthermore plays a role in prevention of the recourse to, and exercising judicial settlement of
international controversies as well as to develop and hence strengthen international law. These
are and must be to some extent complied to by the parties involved creating respect for
international laws. The advisory opinions though recommendations have moral and legal force in
shaping the behaviors of states and international organization (Dunoff & Pollack, 2013).
1.3 Predecessor: Permanent Court of International Justice
It was replaced by the current Permanent Court of International Justice (PCIJ) that was active
between 1922 and 1946 as a part of the League of Nations institution. It was the first permanent
international court in the world that was originally endowed with the power of universal
jurisdiction. The PCIJ thus exercised considerable influence on shaping international legal
principles and also made clear that the idea of a world court could be thereby successfully
realized. Some of its elements and procedures were transferred to the ICJ (Hernández, 2021).
Establishment of PCIJ is therefore a significant turning point in the history of international law A
PCIJ was instrumental in setting up an orderly legal system to prevent conflicts between states
by using other legal means. It was formed in response to the desire to avoid antagonistic
situations by employing the doctrine of law and to foster a perception of order within a global
3
society after the harsh realities of World War I witnessed by the international community.
(Hudson, 1943). That was paramount in the resolution of many legal controversies, as well as
rendering of various advisory opinions that helped to explain and shape the foundations of
present day international law. Among its many accomplishments, PCIJ recognized legal
principles that were to be the lasting hallmarks of international law. For instance, the PCIJ dealt
with questions of sovereignty, treaty interpretation, and the protection of minorities and therefore
established stochastic precedents that shaped international legal practice today (Shaw, 2017).
Some of the landmark cases which are still referred today, for example the S. S. ―Lotus‖ case and
the Chorzów Factory case encompass the set principles of state responsibility and jurisdiction.
Lastly, the PCIJ’s reformation of procedure and also various judicial practices was revolutionary
as well. It thereby helped set procedural paradigms for international legal hearings and hence
regarding the admissibility of evidence, duties of judges. These practices were intended to
promote equal, open, and rational treatment by the Court (Rosenne, 2007). The PCIJ served as
the foundation for the creation of the International Court of Justice (ICJ) when it was formulated
in 1945, and more notably, the ICJ adopted most of its statue, proceedings and several of its
judicial standards from the PCIJ. This helped define continuity and the ICJ was thus able to
maintain the processes of the Permanent Court with a few added improvements. The statute of
the ICJ is similar to the PCIJ, which maintained that the principles and practices, which had been
deemed efficient, were preserved (Crawford, 2023).
1.4 ICJ's place in UN system
It should be noted that the ICJ occupies rather a special place in the system of international
organizations as the main judiciary body of the United Nations. It forms one of the major organs
of the United Nations together with other five; the General Assembly, Security Council,
Economic and Social Council, Trusteeship Council and Secretariat. This incorporation in to the
UN system therefore makes the ICJ a focal point of international law and diplomacy. However, it
also means that the Court’s utility is contingent on the general political processes in the UN
especially when it comes to the implementation of its decisions with the assistance of the
Security Council (Abebe, 2020). The admission of the ICJ into the UN system thus also places
its importance in the enhancement of international legal order into context. Being the principal
judicial body of the United Nations the ICJ supports the UN’s objectives of preserving
international peace and security by offering the means of settlement of international disputes by
peaceful means. This role is important because it affords the opportunity of management of
conflict situations as well as promotion of cooperation amongst states in accordance with the law
(Rosenne, 2007). However, there is a challenge in this aspect whereby ICJ looks towards the
Security Council for the implementation of their verdicts. Even the Court’s judgments and
decisions are enforceable against the subject of the dispute; the enforcement measure is
voluntary and depends on political will of the Security Council members. This results in cases
such as politicization of international law where political interests trump legal ones especially
when powerful nations are involved (Abebe, 2020). For instance, after the state has violated an
ICJ judgment, the Security Council has the power to enforce compliance but the use of veto
4
power by the permanent members will prevent such actions. The relationship between the ICJ
and the Security Council is that it sets the political realities within the UN system. Hence, the
efficiency of the Court goes beyond the legal analysis of its findings and cases, as the Court’s
legitimacy is conditioned by geopolitical politics in the Security Council. This dynamic may
raise issues as to the ICJ’s ability to function as an independent judiciary because the political
pressure may influence the implementation of the decisions of the court (Dunoff & Pollack,
2013).
II. Jurisdiction and Competence
2.1 Contentious cases between states
In relation to contentious cases, the main role of the ICJ is to provide legal dispute settlement
between states. Individuals or organizations cannot be parties in cases before the Court but only
states. These cases are therefore diverse in subject matters such as; boundary disputes, sea
boundaries, and also alleged breach of international conventions. The Court’s decisions in
contentious cases, as it will be seen hereunder, are final in the sense that they are immediately
executing on the parties. As Bonafé (2022) observes, these are frequently intertwined issues of
state responsibility that may significantly affect the development of international law.
Controversial issues have in the past been dealt with by the ICJ through cases which have
involved some of the major and delicate international issues. Hence, in territorial disputes, such
as historical, ethnic-cultural and strategic interests it becomes very important to have the ICJ to
help in peaceful settlement of such contentious issues, which if not well handled might lead to
conflict (Shaw, 2017). In matters like these, not only are the individual states impacted by the
rulings made by the ICJ, but such decisions become the legal precedents for international law.
Maritime delimitation cases are thus another important branch of the ICJ’s activity. These cases
relate to delimitation of the exact geographical extent of states’ maritime zones, which concerns
significant numbers of resources, fishing and economic zones (Tanaka, 2015). The judgments of
the ICJ thus assist in the elucidation of the principles of the international Maritime Law and
hence to provide order and legal certainty to the world’s states in their relations on the high seas.
Of the cases that get to the ICJ, a good number of them are based on alleged breach of
international treaties. These often encompass complex issues of law on treaty interpretation,
application and enforcement (Thirlway, 2016). The involvement of the ICJ in the resolution of
these matters thereby shows that the court acts as the protector of treaty rights where it monitors
the compliance of states to their legal obligations under the treaties. If that is so, the mandatory
character of the decisions made by the ICJ is one of the key sources of its power. When states
submit to the jurisdiction of the Court, they accept to be bound by its decision and this has the
effect of strengthening acceptation of the rule of law in inter-state relations (Rosenne, 2007).
Nevertheless, the actual realization of these decisions might be problematic especially in the case
of certain powerful states, which makes it clear that law and politics are intertwined in the
international practice (Abebe, 2020).
5
2.2 Advisory opinions for UN bodies
However, what the ICJ also has jurisdiction to do is to offer advisory opinions in matters of law
subject to its consideration when such matters have been referred to it, by any of the legitimized
organs of the UN and the affiliated specialized agencies. Even though these opinions do not have
legal precept, they thus exert substantial pressure and also frequently contribute to the formation
of International law. In this paper, Hilpold (2020) analyses the advisory jurisdiction of the Court,
arguing that it serves the purpose of giving legal interpretations to the international community;
however, such mandates may also entail political disputes such as the Kosovo opinion case.
Serving the advisory function, the ICJ can settle involved questions of international law which in
one way or another appear in the practice of international relations. These opinions are aimed at
giving legal interpretation and advice on uncertainties of international law as other UN organs,
specialized agencies and its membership undertake their functions (Thirlway, 2016). Advisory
opinions can be on various subject fields such as; rights of individuals, the status of environment,
and hence the lawfulness of the employment of power. The advisory opinion given by the ICJ in
2010 concerning the legality of declaration of independence of Kosovo is among the more
famous opinions supported by the court. Sought by the UN General Assembly, this opinion
delivered on whether the declaration disrespected international law (Hilpold, 2020). Although
the Court found that the declaration did not breach any international law, the said opinion raised
dissatisfaction and politicization among the political domain and exposed that the ICJ encounters
difficulties because of handling questions involving an acute political aspect. Even though they
do not have the force of legally binding decisions advisory opinions make a substantial
contribution to the elaboration of the progressive development of international law. In many
cases, they play the roles of providing official meanings to the principles of law, hence forming
the subsequent legal precedents and state practice (Rosenne, 2007). To this, the opinions have
the backing of the Court and the exhaustive analysis that is conducted in coming up with the
final decision. However, the compelling features of the ICJ occur where it has an advisory
jurisdiction which is vital in the working of the United Nations. It offers the formation for the
lawful management of international concerns, thus promoting the UN agenda of preserving
international peace and security (Dunoff & Pollack, 2013).
2.3 Compulsory and optional jurisdiction
On this manner, the jurisdiction of the ICJ is based on consent of the states. States can accept the
Court's jurisdiction in several ways: either by way of a special consent for a particular
controversy, by virtue of a treaty providing for the jurisdiction of the court, or under the optional
clause pursuant to Article 36 paragraph 2 of the Statute of the ICI. The final of these two known
as compulsory jurisdiction enable any state to proclaim in advance that it accepts compulsory
jurisdiction of the Court in respect of other states that also recognize the obligation. The modality
of this system makes it somewhat controversial as Lando notes that since the jurisdiction is
optional, the Court might at times lacks the appropriate means by filling what he termed as some
of the most significant gaps in international law. The jurisdiction of the ICJ accepted through
6
special agreement, also known as compromise is a procedure through which states will agree that
a given dispute shall be referred to the Court. This method is evidence of the fact that both the
parties agree to let the Court handle the case, making both of them cooperate with each other in
solving the problem (Shaw, 2017). However, it needs the will of both the states demonstrate
willingness to submit their matter to ICJ, which is not possible in chronic most critical conflicts.
Acceptance of the ICJ jurisdiction can also be through treaty by invoking of jurisdictional
clauses in treaties. These clauses are placed within numerous international treaties, which state
that any issues associated with the competence of the treaty, as well as the disputes related to its
application or interpretation, shall be addressed to the ICJ (Thirlway, 2016). This method
anchors the states to the jurisdiction of the Court whenever they are parties to the treaty in
question and the route that takes is simply legal. The jurisdiction of the Court in relation to the
commitment made through the clause declaration under Article 36(2) is even more extensive.
Countries that make this declaration intend in advance to accept the jurisdiction of the Court in
legal controversies with other countries that have also made the same declaration. Such forms of
acceptance enhance the rule of reciprocity and increase the Court’s ability to resolve cases
(Rosenne, 2007). However, as rightly said by Lando (2020), since these are optional
declarations, states can accept the jurisdiction of the ICJ with or without reservations or even
withdraw their declarations limiting the jurisdiction of the ICJ and possibly the effectiveness of
the ICJ in the resolution of some of the most important international disputes.
2.4 Limitations on ICJ authority
However, the ICJ has some limitations concerning its powers to undertake and determine a
particular case. First of all, it can hear only the cases in which states agreed on its jurisdiction.
Second, although its decisions are authoritative for the parties in the case, the Court does not
have measures for enforcing its decision. There is always political consideration when using the
enforcement agencies, which is a method of enforcement through the UN Security Council.
Furthermore, the ICJ is adjudicatory body and cannot hear cases of the individual or
organizations who are not state parties, which matters in today’s international relations systems.
As far as the role of the ICJ is concerned, Krisch (2021) notes a rising tendency of hostility to the
international courts among states that used to delegate their jurisdiction to these courts but seem
to have changed their mind perceiving infringements of their sovereignty. Thus, the need to
obtain consent of the state hampers the work of the ICJ regarding the disputes partly. The
Court’s jurisdiction must be accepted by the states through consent in the form of consent to the
court jurisdiction, treaties, or declaration under the article 36(2) of the ICJ statute (Lando, 2020).
States can thus opt out of the Courts jurisdiction, if politically sensitive issues are at stake, and
thus limit the ICJ as the court of international disputes. There are also no real mechanisms for
direct enforcement of verdicts which creates additional problems for the ICJ. However, to
support these judgments, it does not have original enforcement powers although they are legal or
binding in nature. It depends on the Security Council while the latter is political in nature that
hampers the action making process. For example, permanent members of the Security Council
may employ their veto power to reluctant the implementation of enforcement measures thereby
7
eradicating the Court’s verdicts (Abebe, 2020). Also, the restriction of the ICJ to deal with cases
involving only legal persons has also been regarded as a disadvantage that is becoming more and
more apparent. Given the fact that today’s international relations involve not only states, but also
multinational corporations, and other international organizations, the jurisdiction of the ICJ
seems to be quite archaic. This limitation reduces the position of the Court in dealing with most
of the modern day international concerns that cut across multiple actors especially the state and
non-state actors (Thirlway, 2016). Though, Krisch (2021) state another general discourse of
criticism and even erosion of international courts comprising the ICJ. While making decisions on
the international level states face the dilemma of loyalty to the international law and loyalty to
their state; thus, some of them consider international adjudication as an intrusion of the state’s
authority. This rising skepticism can thus translate into less compliance with the international
courts and hence unwillingness to accept their jurisdiction, which, in turn, would limit the ICJ’s
functioning even more.
III. Composition and Structure
3.1 Election of ICJ judges
The ICJ is made of 15 judges chosen for a term of nine years by the UN General Assembly and
the Security Council. The election process is aimed at the provision of the countries with the
world’s major legal systems and at geographical distribution as well. Judges must be of good
behavioral pattern and moral integrity and they must meet the following criteria: They must
either be qualified for appointment as a judge of the highest court of their respective country or
be jurisconsults’ of recognized competence in international law. According to Grossman (2020),
this election process is vital to ensure that this court remains independent and has the credibility
of the society though it may not be immune to political influence. The structure of the Court to a
certain extent was to have a mixture of cultures and legal systems to comprise the ICJ. This
diversity is important for the Court which has to perform as a genuine international court that can
and has to give consideration to numerous kinds of legal disputes. The demand to be a judge who
has qualifications for the highest judicial offices or an individual who is an acknowledged
specialist in international law insures that the Court’s decisions are based on significant legal
experience and strong moral character (Rosenne, 2007). However, the election process which is
supposed to provide an opportunity to select people who possess these and other qualities is not
beyond politics’ interference. Thus, some of the states put more emphasis on the strategic and
political aspect when endorsing the judicial candidates. This dynamic can also bring in biases
and also the perception of the Court as possibly partial or bias especially towards the whites
(Grossman, 2020). For instance, the strong states can influence the selection of the candidates
who share similar legal ideas or political stance enhancing the probabilities for bias in the
international judiciary. Nevertheless, the present research has identified several key factors
which point to the deficiency of the ICJ’s selection and election procedures, yet by and large, the
strict criteria and systematic mode of selecting the judges help in choosing competent and
8
unbiased individuals. The requirement of the majority approval in the General Assembly and
Security Council so as to shortlist the candidates for the appointment as the judges is a safeguard
against the biased appointments; this ensures that international judiciary enjoys respect in the
international community (Thirlway, 2016). The ICJ has moreover increased the probability of
broader perspectives on the interpretation of international law since it has a diversified
membership. Such diversity is equally important given the fact that legal matters are never far
from cultural and regional differences in the contemporary globalized society. This means that,
having different backgrounds, judges come with different perspectives, thus enhancing the
Court’s proceedings, and also help come up with more credible and acceptable judgments’ on an
international scale (Shaw, 2017).
3.2 Chambers and special chambers
This is the usual structure of the ICJ although it may from one or more chambers where
appropriate to do so in order to address certain categories of the case or certain dispute. Such are
the Chamber of Summary Procedure and the special chambers created in the course of the trial
pursuant to the parties’ application. It may be said that, depending on the type of cases, special
chambers can be established, for example, for handling environmental issues. Oellers-Frahm in
his paper made in 2021 pointed out that these chambers can provide possible advantage of
providing more flexibility and efficiency in the handling of cases and thus the more state may be
inclined to submit cases to the Court. Flexible procedures thus can be attributed to the use of the
small number of chambers which enables the ICJ to set procedures in a manner which best suits
every given case. Instances such as the Chamber of Summary Procedure are intended to resolve
clear-cut matters quickly while being good on procedure but not on substance (Thirlway, 2016).
This has a positive impact whereby it helps in the expeditious determination of disputes hence
makes the Court more easily accessible to the states that maybe in dire need of judicial
determination of their disputes. Quoting Rosenne, special chambers that are ad hoc and created
to attend to the parties’ demand apply specific expertise and modifications of procedure to
satisfyingly address intricate situations. These chambers allow the ICJ to use resources sensibly
and distribute justice skills properly so that every case gets proper consideration. Specific civil
law chambers assigned to different categories of cases including environmental ones show an
appropriate reaction to the new challenges of the world by the ICJ. Specialized chambers are
useful in creating efficiency as the court may get to address specialized fields of international
law and in the process help in the formulation of legal norms governing the emerging
phenomena (Shaw, 2017). This specialization thus improves the Court’s capacity and also scope
of responding to modern standards of global issues, making states use the Court more as an
option thereby for dispute settlement. According to Oellers-Frahm (2021), these chambers
provide such options that may enshrine states’ interest in the ICJ. In this way, the Court therefore
improves protection of carefully designed procedures for setting up dispute resolution
instruments and also effective case adjudication, which in turn increases its potential for
contributing to the avoidance of international conflicts and hence their resolutions with
compliance with legal principles.

3.3 Role of the ICJ President
The Presidency of the ICJ is provided by the election of the judges in the court though for a
period of three years. Powers and duties of the President of the Court include managing,
organizing, and leading the work of the Court, chairing the sittings and overseeing its work.
Judicial interpretation in Kenya is done by judges and in the event of a tied vote among the
judges, the President has the casting vote. Another diplomatic function includes rendering of the
court’s representation by the President, implementing and preserving cooperation with
international organizations. Lauterpacht (2021) continues the tradition of stressing the fact that
the President plays a crucial role in terms of defining the further development and the trajectory
of the Court. Presidential election is thereby another crucial event in the framework of the ICJ,
which thus proves the court’s focus on efficient leadership and also non-interference by the
authorities. The President of the United States includes significant judicial roles in their job
description and performs examples of an essential judicial executive duty like hearing cases or
assuring the Americans’ legal processes’ fairness and proper running (Shaw, 2017). As seen
before, this duality highlights the President’s capacity to shape the court’s business and protect
its judicial independence. Apart from internal communicative roles, the President of the ICJ is
involved in external representation, and diplomatic business of the court. In that regard, the
President advances the Court’s mission as the member of the International legal system and
develops contacts with other international organizations (Rosenne, 2007). This diplomatic
function is therefore necessary for the promotion of the organization’s institutional agenda and
also for the Court’s legitimization globally. As Lauterpacht (2021) also pointed out, it is annually
that the president plays a central role in determining what cases the Court takes and what kind of
jurisprudence it wants to pursue. By managing the Court’s affairs and also making crucial
decisions, the President influences the Court’s reaction to new legal problems and hence
maintains the consistency of its practice in the field of international law (Thirlway, 2016). Given
the fact that the ICJ is governed by the Rules of the Court, the President of the ICJ plays a central
role in the Court’s management. Besides the administrative role, the President also determines
the Court’s judicial processes and hence guides diplomatic processes when it comes to the
relations with other nations. In exercising leadership responsibility in judicial process and
external relations, the President is in a central position in providing stewardship to the ICJ’s call
as the protector of international justice and legal system (Lauterpacht, 2021).
3.4 Registry and administrative support
The ICJ is assisted by its Registry which acts as the Court’s service entity. The Registry is led by
the Registrar and includes all functions with regards to case files, dissemination of the decisions
and opinions of the Court, correspondence with the parties of a case and the public. It also offers
language services because as it is known the Court works in two languages, English and French.
In his contribution of 2020, D’Aspremont underscores the centrality of the Registry in the timely
operations of the Court and as the keeper of the Court’s memory. Principal among them is the
Registrar of the ICJ who supervises several critical operations that go into the running of the
10
Court. Some tasks entail the provision of administrative needs for hearings, handling of
documents, and the organization of cases (Shaw, 2017). In providing administrative support the
Registry minimizes encumbrances on the judges allowing them to effectively perform their
constitutive roles of dispensing justice for the Court thus improving on the Court’s processes and
outcomes. It ensures that the Court’s decisions, opinions and procedural information are
disseminated promptly to the parties involved and the general public (Thirlway, 2016). This is
important to inform the public for them to have faith in the global judicial system especially the
ICJ. Interpretation and translation services offered by the Registry are therefore crucial to ICJ’s
mandate of accessing all persons. In this case since the Court conducts proceedings in both
English and French the Registry provides for interpretation and translation of the legal writings
and parlance as well as interpretation of every spoken word (Rosenne, 2007). This linguistic
support is necessary so that communication is only witnessed between the judges and the parties
involved as well as the observers of different linguistic backgrounds. In his contribution to this
volume of 2020, D’Aspremont agrees with this assertion by noting that through the organization
and archiving of relevant documents, the Registry equally performs an important institutional
memory responsibility to the Court. Historically, records and papers are kept through the
Registry to preserve past decisions and past precedent with the goal of the continuity of the
jurisprudence of the ICJ (Lauterpacht, 2021). It may be a legal duty that is indispensable for
ensuring that there is a continuity of legal policies, understandings and decisions in an institution
and for helping evolve the law of nations progressively. The Registry of the ICJ is composed of
officials mainly tasked for the substantial administrative support of the Court. As the main
administrative arm, the Registry assists the ICJ by performing important functions that include
case management, issuance of decisions, interpretation services, and record keeping hence
enabling it deliver its mandate of efficient and fair dispute settlement (D’Aspremont, 2020).
IV. Procedural Aspects
4.1 Initiation of proceedings
Proceedings before the ICJ can be initiated in two primary ways: Either through the notification
of a special agreement between states to refer a case to the Court or by one State against another
State. In both contexts, the states must have agreed to the jurisdiction of the Court beforehand.
Lando (2020) stated that the institution of proceedings is a significant moment that is the end
stage of diplomacy and the parties willingness to obtain rights through legal procedures. It is
evidenced by a treaty between parties for a particular controversy to be referred to the ICJ in
order to establish judicial techniques to be used in dealing with the controversy at hand. This
method can be considered as consensual since states will decide on the extent and conditions that
the Court is going to resolve the states’ dispute (Shaw, 2017). As it can be seen, special
agreements can relate to different kinds of the conflict, for instance, territorial, maritime or
treaty, as well as the controversies over the interpretation of the existing treaties; therefore, the
Court does respond to the different aspects of the international relations. However, a vertical
11
application where one state resorts to the court against another state is only applicable where the
respondent state has agreed to the jurisdiction of the ICJ. This action of the initiating state is
therefore important in demonstrating the confidence the state’s government has in the Court’s
ability and also impartiality to handle the case in a way that would give each party its due. It also
exhibits respect for the rule of law and the international law system as states submit to the
disposition of an international court. In the both cases, once there is a basis for proceedings to
begin, the ICJ may be requested to indicate measures for the protection of rights at the
investigation stage prior to the final decision. These procedures are only of a provisional
character and are used where there is a necessity to avoid actions from which it is impossible to
restore the parties; or where the purpose of preventing the continuation of activities that are
unlawful or require changes until the final decision of the court. Provisional measures thus show
that the Court intervenes to prevent situations that may harm international peace and also
stability at the right time. All in all, the use of special agreements or unilateral application in
initiating proceedings before the ICJ has been thus an important landmark in the process of
dispute settlement in international law. It depicts therefore states’ respect for the Court’s
jurisdiction and also their willingness to follow legal means instead of legalism to solve existing
crises and hence differences. The following of strict legal procedures cements the position of the
ICJ as a one of the bedrocks of the international legal system for states and enhances
predictability and compliance with laws internationally.
4.2 Written and oral phases
ICJ proceedings typically consist of two distinct phases: as it was highlighted in the written
phase and the oral phase. In the written phase, parties prepare the detailed memorials and
counter-memorials, but sometimes replies and rejoinders may also be prepared. These documents
are thus used to establish each party’s case and also the legal and relevant arguments coupled
with proofs to support them. This stage enables the Court to have an adequate understanding and
assessment of the issues and the issues surrounding the case and before actual oral hearings start
(Bjorge, 2020). The written phase thereby remains important because it offers a framework
within which parties can give well-coordinated and also more detailed arguments. It could be
remembered that in memorials and counter memorials there are a lot of advocacy of law,
reference to the law that governs the case and citation of past cases to support the case. Such
detailed recording moreover assists the ICJ judges in giving well-informed consideration to legal
aspects of the case and hence come up with a well-informed view of the case. After that is
complete, the agents and counsel of each and every one of the parties to the case develop and
argue their case out right in front of the Court. Bjorge (2020) opines that the oral phase creates
opportunities for the parties to amplify their written submissions, to answer questions that the
judges might have, and most importantly to have an interactive conversation which in turn,
highlights the controversies in relation to the provided legal issues. The oral phase is not an oral
repetition of written arguments but advocacy and real life debating in front of the judicial panel
(Thirlway, 2016). It therefore enables the judges of the ICJ to; gain further insight into the
certain elements of the case, clarify the certain legal questions, evaluate the reliability of claims
12
and also submissions of the parties. In summary, it can thus be stated that an organized nature of
proceedings in the ICJ suggested by the division into the written and also oral phases indicates
the court’s logical and hence thorough approach to defining the sovereignty disputes. Thus, the
Court strengthens its probability of arriving at well-considered determinations that protect
international law since the detailed written paperwork pairs with oral arguments that physically
engage the Court (Bjorge, 2020). The decision-making procedure in this case highlights the ICJ
as a main forum where original contentious international questions are resolved through legal
rationality.
4.3 Deliberation and judgment delivery
Once the oral cases are over, the next stage is the deliberation stage of the ICJ in camera, where
the judges deliberate on the case and the judgment. This stage is important and significant in a
way because it enables the judges to discuss with each other and deliberate – or to share their
impressionistic analysis of the case, and to consider the submissions made by the parties to the
case as well as the principles of international law governing the matter at hand (Proulx, 2023).
During the deliberation, the judges make a vote on the end result of the case, which becomes the
court’s judgment. After the deliberation, that involves the formulation of the findings of the
Court and the grounds of the judgment, the drafting of the judgment ensues. Every single judge
is allowed to participate in the drafting of the case which makes the result more considered
(Shaw, 2017). Notably, the judges may also opt to write concurring or dissents opinions which
show deviations or controversies over legal nuisances that the case presents (Thirlway, 2016).
Proulx (2023) explicates that these deliberations and consequent judgments’ remain rather
crucial when addressing international law. Judgments of the ICJ settle the law and give legal
standards which regulate the behavior of states in the international sphere. Looking at the UN
Convention on the Rights of the Child, the Court helped specify and establish the international
law norms in terms of children and justice relating to the international treaties, customary
international law, and the general principles of law. When the judgment is entered, it is read in an
open session of the Court, which continues the Court’s policies of openness and responsibility in
its affairs, as announced by Rosenne (2007). The judgment becoming recourse for the parties to
the case thus imposes the obligation to accept as well as execute the Court’s decision as well as
their obligations under international law (Bjorge, 2020). The above enforceability therefore
strengthens the ICJ as being a premier voice in the regulation of peaceful resolution to disputes
in international relations and also in the promulgation of the rule of law. In conclusion, the
deliberative process that takes place at the ICJ and the final delivery of its judgments act as the
main agents in the progression of international law and maintenance of global order and peace
(Proulx, 2023). In this context, through its intensive arguments and the formulation of rational
decisions the Court enhances the settlement of intricate legal controversies that are pertinent to
the states or other participants of the international relations and contributes to the creation of the
legal stability in the world.
13
4.4 Enforcement of ICJ decisions
Like most international judicial bodies, ICJ’s judgments are binding on the parties to the disputes
but it does not possess direct enforcement machinery. Its efficiency is therefore strongly tied for
such judgments to be effective states have to be willing to follow international legal requirements
(Al- Qahtani, 2020). In the event that a state defaults to implement an ICJ judgment the case can
be brought to the UN Security Council for action to be taken. Under the UN Charter the UN
Security Council has all the powers to take actions like sanctions or force in order to enforce the
judgments’ given by the ICJ (Shaw, 2017). However, the enforcement process can take a long
time and be pressed back by political interests, especially concerning the states that are either
powerful or have allies in the ability’s jurisdiction. The P5 members, United States, China,
Russia, France and United Kingdom have the authority to veto any change of the body’s
procedural law, and substantive resolutions which can sometimes hamper the decisions of the
council (Al-Qahtani, 2020). From the Security Council enforcement it is difficult to conclude
that the ICJ has a major drawback of inefficiency in addressing interstate disputes. The
judgments of the Court may be moral and legal occurrence that can shape states’ behavior and
change the international relations; nevertheless, they determine by political willingness and
international cooperation (Thirlway, 2016). These findings thus point to the prevalence of social
norms and also reputational concerns that compel States to abide by their ICJ obligations, This
shows therefore that States’ compliance with international law and hence diplomatic norms
results from the driving force or motivation from the international community. Therefore, in
general, despite the ICJ’s significant function in the resolution of controversies and the
clarification of international law, the court lacks strong enforcement power proven by the
obedience of the states and the politically charged framework of the UN Security Council (Al-
Qahtani, 2020). To thus overcome these challenges, further work is hence needed in the field of
international law’s development, in the support of the accountability of the international actors,
and also in the improvement of international dispute-settlement mechanisms based on the rule of
law.
V. Landmark Cases and Contributions
5.1 Territorial and maritime disputes
In this sense, it has been therefore rightly stated that the ICJ has certainly been able to provide
important determinations regarding complex territorial and also maritime matters concerning
states, thus positively influencing the formation of international law. Most of these involve
social, historical, geographical and legal analysis and judgment which cannot be arrived at a
superficial level. With regards to the ICJ role, Heieck (2023) has highlighted on how it has
enriched the law of the sea especially in maritime delimitation. For instance, the Court’s
judgment in 2018 Costa Rica v Nicaragua case provided guidelines for demarcation of EEZs and
continental shelves. This thus determined not only the certain conflict between the two states but
also shed the light upon the interpretation of the principles of the maritime law to the
14
international audience. Besides, the ICJ has heard cases in territorial conflict, which involved
instance of decolonization as well as sovereignty. The advisory opinion of the Court, given in
2019 in the case of the Chagos Archipelago sovereignty dispute between Mauritius and the
United Kingdom. The opinion thus outlined such aspects as; self-determination and also
decolonization, stressing on the subject’s right to territorial integrity and hence control over the
resources. The ICJ delivers these judgments and also advisory opinions to the world, and hence
they are considered quite influential in International Relations and law. It avails legal
understandings of the issues, sets up anticipations that help in determining other similar cases as
well as help in the non-violent resolution of disputes between states (Shaw, 2017). Recognition
of the ICJ as an institution handling such disputes give a clear testimony of its core function in
maintaining international law and also order and encouraging commitment among nations. As
the Court makes its decisions, it in a way assists in the development and enforcement of
international law as it deals with legal questions and helps to formulate solutions for international
disputes in relation to justice and fairness (Heieck, 2023).
5.2 Use of force and intervention
In this regard, the ICJ has been most active in defining international law in the sphere of use of
force and intervention as well as in dealing with major case that have set legal precedents or
provided important jurisprudence in this sphere. Gray (2022) discusses the following issues of
the ICJ jurisprudence as far as the use of force is concerned: One of the notable cases is
Nicaragua USA of 1986 where the Court dealt with the questions of non-intervention and state
responsibility. His judgment hence underlined principles of sovereignty and non-entrenchment in
affairs of other states, which already has remnants at the onset of the third millennium. Still in
2022, the Armed Activities case- (DRC v. Uganda) marked a new development in the ICJ in
relation to state responsibility for armed intervention and occupation. This case thus focused on
Uganda in the DRC affair and hence defined the rules of legal responsibility of states for
interference in other’s affairs. Once again, the Court therefore upheld the territorial integrity,
non-use of force and also sovereignty standards as the key factors in supporting of the
international peace and security. These cases depict the ICJ as one of the most significant judicial
organs in the determination of international legal issues to do with the application of force,
interference and responsibility of states under the international law (Shaw, 2017). As a result of
applying and interpreting of significant legal norms and principles, the Court participates in
construction of the system of the international legal obligations, which is oriented to maintain the
rules’ based world order and to exclude conflict between states. Thus, the analysis of use-of-
force case law can be regarded as a summary of the ICJ’s activities by interpreting the principle
as its peculiarity to sustain international law and oversee the states’ compliance with relevant
legal commitments. In this way, the Court delivers legal guidelines and resolutions when
different affairs are ambiguous, sets legal precedents, and maintains rules of state behavior in
relations with other states (Gray, 2022).
15
5.3 Diplomatic and consular relations
As mentioned above, the ICJ has undoubtedly actively participated in the development of the law
concerning diplomatic and consular relations, the legislation of which has been enriched by the
consideration of this Court in significant cases aimed at the determination of rights and
obligations under international law. Specifically, the ICJ furthermore offers a practicum of how
the Vienna Conventions on Diplomatic and also Consular Relations have been interpreted and
hence applied in the international legal context of the contemporary world, which is considered
as two of the most important treaties that regulate the behavior of missions and consular posts.
Two landmark cases therefore illustrate the Court's impact in this field, they thus include:
Moreover, the first important case, the United States Diplomatic and Consular Staff in Tehran
case of 1980, related to the Iran hostage taking crisis, discussed such questions as diplomats’
immunity and their safeguarding. This judgment will act as a one clear authority for the
immunity of diplomatic premises and at the same time will remind the host nation that it has the
responsibility of protecting the physical integrity of the diplomatic body of the foreign mission.
Secondly, the case known as the LaGrand case or Germany v United States of America, 2001, in
which the main focus was made on consular rights and states’ obligations to foreign citizens
being detained. On that point the Court underlined the principle of consular notification and
access stating persons ought to have the right to be visited by officials of the consulate of their
home state where they are detained in a foreign country. The decisions of ICJ elaborated above
have not been devoid of real-world consequences for diplomacy and individual’s rights in
connection to the consular law. The Court hence helps to maintain agreement and also order in
legal relations, diplomatic and also consular practices all over the world by establishing the
clarification and hence the path that has to be followed according to the agreements in the
Vienna Conventions. The following are therefore the findings of the study; the cases on
diplomatic and also consular relations mentioned by the ICJ are thus an indication of the court as
a guardian of the law and principles on state conduct. Thus, by delivering its judgments in
practice like those explained in the current paper, the Court advances diplomatic immunity,
consular protection, and beneficial international interactions and relations (Miron, 2021).
5.4 International environmental law developments
The ICJ has thus enhanced its involvement considerably in addressing issues of environmental
concern and hence enhancing the charter of environmental law at the international level. In
Schrijver (2022), the author critically discusses the Court’s progressively developed case-law on
environmental questions—arguing that it plays a disputably pivotal function in addressing global
environmental issues. Some of the landmark cases include; Gabčíkovo-Nagymaros Project case
Hungary/Slovakia 1997 and Certain Activities Carried out by Nicaragua in the Border Area
Costa Rica v Nicaragua 2018 are some of the cases that have been vital in shaping the concepts
of sustainability and environmentalism. Regarding the territorial and also maritime disputes; it is
furthermore worth noting that the determinations made by the Court have helped to avoid wars
and also contribute to the preservation of international peace and security. As for force and also
16
intervention, the ICJ has therefore refined concepts from the UN Charter, providing some
directions for the states’ interactions. Furthermore, decisions in diplomatic and consular relations
have relevance for the actual inter-state relations and protection of the rights of individuals in
accordance with the existing rules and the obligation. This interaction thereby means that the ICJ
has been thus becoming proactive in the discharge of its functions by adapting to evolving global
crises. Nonetheless, there are open discords and critiques involving the Court as acknowledged
by Akande and Tzanakopoulos (2023) especially in areas that are more contentious such as the
notion of aggression. Moreover, as Fitzmaurice (2021) points out, the ICJ has also developed
progressive roles in the environmental law but some have claimed that the court has contributed
insufficient commitment in addressing pressing global environmental challenges. Lastly, it is
clear that the ICJ committed to the development and interpretation of international law in which
territorial disputes, the use of force diplomatic relations, and environmental concerns are clear
that the ICJ is a principal judicial organ of the United Nations. Its decisions thus do not only set
legal precedents but can also impact on state actions and also the international rules, for the
common goal of maintaining order, justice, and hence sustainable development in the
international system.
VI. Challenges and Future Prospects
6.1 State compliance with judgments
Adherence to the ICJ’s decisions by States, are indeed one of the significant factors that
determine the Court’s capability in the settlement of interstate disputes. Al-Qahtani (2020)
discusses this issue, noting that the problem arises from the fact that the ICJ operates only when
states opt in on a voluntary basis and the enforcement mechanisms are indirect and involve the
Security Council of the United Nations. It is however important to note that there has been lack
of compliance with the decisions of the ICJ in many states although most of the states adhere to
these standards Most cases of non-compliance are a big blow to the Court besides weakening the
credibility of the international law. However, Al-Qahtani stated that compliance is dependent on
certain factors including; political will, domestic pressure and the type of dispute at hand. For
instance, examples such as Nicaragua case and United States early reaction reveal kind of
conflict between legal sovereignty and international law. This means that the ICJ does not have
the power to directly force states to obey the ruling it has made, so it has to rely on diplomatic
diplomacy and international pressure. In matters of non-compliance, the Court may refer the
concerned matter to the UN Security Council though this is not beyond political influence due to
the influence of the powerful states. The ICJ has thus a significant role in maintaining stability in
the international society by enhancing and also inspiring respect for the international legal order
and hence responsibilities of states parties involved in international negotiations under the UN
Charter. Although the ICJ provides a useful platform for solving the peaceful disputes, the
problem of compliance is thus one of the evidence that international law enforcement remains to
be a quite complicated issue all the same. These and also other challenges therefore call for
17
further developments of the interstate law and hence improve arrangements for the monitoring of
state compliance with the ICJ decisions.
6.2 Expanding jurisdiction and accessibility
Guilfoyle (2021) talks about major difficulties in the practice of the ICJ concerning; its
jurisdiction and access to international dispute resolution. Peculiar to the above challenges is the
fact that the jurisdiction of the Court is optional in many cases thus limiting the Court from
handling many international disputes. Some of the reforms that Guilfoyle only posits are the
attempts to enhance the number of the states that embrace compulsory jurisdiction and to
augment the Court’s capacity for advisory opinions. Opening up obligatory jurisdiction would
mean that more states should be urged to make declarations under the Article 36(2) of the Statute
of the ICJ bringing obliged to accept the jurisdiction of the Court in the disputes with other states
consented to do the same. It can therefore expand the institution’s applicability in contentious
international affairs and also improve its functioning as hence the main judicial body of the
United Nations. In addition, improvement of accessibility has to be the next step especially for
those less populated or less economically developed states that may have a limited access to the
international judicial frameworks. To enhance accessibility, Guilfoyle thus put forward several
recommendations including; rationalization of procedural routes, lessening of expenses
connected with legal actions, boosting of practical and also financial assistance to the regions
lacking resources for their interaction with global judicial processes. According to Guilfoyle, the
above challenges can be overcome to enable the ICJ to continuing with its mandate of solving
legal disputes between states and promote the use of international law in the resolution of
international disputes. The objective of these reforms is to thus enhance the functioning of the
Court as an agent that; safeguards international law and also contributes to the creation of
stability in the world while at the same time to ensure genuine and hence fair participation of
different states in international legal relations.
6.3 Relationship with other tribunals
In the global system of international dispute resolution, Alter (2021) identifies a dynamic process
of continuing establishment of international courts and tribunals with focus on their prospects
and prospects of difficulties. In this intricate structure of the legal framework, the International
Court of Justice or ICJ which is also known as the ―World Court‖ is very crucial along with other
functional tribunals like International Tribunal for the Law of Sea and the International Criminal
Court. Alter identifies one major drawback, namely forum shopping and confrontations in
jurisprudence due to the abundance of IJBP. Particularly, states and parties may select certain
forums because they presume to gain an advantage either in the legal-interpretation or the
procedural treatments. This diversity may cause certain problems to international legal order and
its predictability and unity though the ICJ established in this system may face some difficulties in
preserving its dominance in the given sphere. To the same end, Alter also points out on the
multifaceted nature of this phenomenon as holding positive implication all the same. Due to the
fact that the specialized tribunals can discuss the case with each other and work in parallel to one
18
another, such connection and cooperation promote deeper legal analysis in terms of both national
and international law systems and their coordination in the course of case consideration. The ICJ
as the court of compulsory jurisdiction in international relations with an overall character of the
UN system is capable of giving general guidelines on international law respecting the specialized
competencies of other legal bodies. In this regard, the ICJ faces the task to become, on one hand,
the place where interstate disputes can be solved, and, on the other hand, the place which
develops international law. It therefore calls for initiation of relations with other international
courts and also tribunals, effective handling of jurisdictional conflict, encouraging harmonization
and hence convergence of laws across the judicial systems. Summarizing, it is thus possible to
state that the development of international courts has its benefits and drawbacks, and also the
management of these complex processes can thus contribute to an increase of efficiency and
hence recognition of international conflict-solving instruments. Thus, the ICJ can effectively and
proactively contribute to the creation of a more comprehensive and solid system of international
legal norms that would be beneficial for protecting international peace and justice.
6.4 Evolving role in global governance
To that end, Krisch (2021) examines how the ICJ is positioned concerning trends of proliferating
doubts about the roles and tasks of international courts and tribunals. The general reaction
against these institutions is also important for Stroup to bring up in order to continue explaining
the specific tactical actions the ICJ must take in its fight to remain relevant regarding its primary
function as the foremost international dispute settlement agency in the world. The globalization
processes are transforming themselves and new form appear new form new challenges include
climate change, cyber security and international terrorism, thus, Krisch can shout that the ICJ
experience can be carried out in the new field. Chesterman (2021) is an example of such an area
since the author explains his or her perspective on the ICJ’s ability to address the challenges of
cyber security. He also raises awareness with reference to the maturity level between the Court
and the current technological and geopolitical environments so that it anticipates the controversy
associated with cyber activities. Hence, Chesterman also points out that as cyberspace endangers
sovereignty and poses a threat to international security, the ICJ may well be in a place to provide
heuristic understanding of the legal rules that should be adopted in cyberspace. In order to
effectively address these challenges and opportunities, the ICJ may need to increase the
institutionally of the court, as well as the rules of the court to be able to adequately address
cyber-related cases. These could have included cultivating the specialized knowledge in its
judges and in its registry staff, launching modifications into to the procedure rules which will
enable the consideration of digital evidence and cyber-specific legal claims, and forming
cooperation with other international organizations and national governments governing cyber
security. Should the ICJ take these new and emerging challenges as a point of contact and
expand its jurisdiction where needed, then the court can enhance its role as one of the foundation
blocks of the international legal framework. This preemptive action not only strengthens the
jurisdiction of the Court but also enhance its capability on handling international affairs and
19
addressing its goals in bringing about peace, stability and justice in this very much globalizing
world we are now in.
