The Sources of International Law shape the foundation for how states relate to one another in the global community. Formally recognized sources are outlined in Article 38 of the Statute of The International Court of Justice, where they are divided into primary and subsidiary sources.
Let's explore which sources these refer to, explain their dynamics, and discuss why international law is essential for preventing chaos. Whether you're already familiar with international law or just starting out, this post will provide a
comprehensive overview of its intricacies! With carefully nuanced facts and illustrative examples that everyone can easily understand, embark on what knowledge base about the international legal system awaits.
Treaties: The Written Agreements Between States
A treaty is a formal agreement between two or more states, supported by their mutual consent and based on international customary law, resulting in an obligation to observe its terms.
The Role of the United Nations Charter in International Law
The United Nations Charter is the foundation of international law, containing key principles guiding relations between states. The Preamble sets an objective to establish friendly relations amongst nations based on mutual respect for equal rights and self-determination of all peoples.
Furthermore, Article 102 reinforces this goal by requiring that every treaty or other agreement between members must be registered with the UN Secretariat to be recognized as valid among signatories.
Additionally, the charter prohibits the use of force within Article 2(4) while affirming each State's sovereignty under Article 2(1).
Likewise, Article 103 outlines that if one member state has obligations arising from domestic laws or a dispute arises out of more than one source of international law (including treaties), it has precedence over any conflicting mission acknowledged by another Member State under their respective constitutional system.
This helps ensure fairness and clarity when there are multiple potential solutions depending on respective interests and interpretations. In addition to these codified rules regarding state behavior globally, the charter is active in ensuring peace and security worldwide through capacity building and dialogue around legal issues such as human rights protections governing States’ actions against their own citizens.
It seeks to support social progress by promoting justice and adherence to rules established by international conventions as well as national courts' rulings, allowing for continuously developing sources of legal guidance where needed.
Customary International Law: Unwritten Practices and Norms
Explore existing international legal norms and how they come to be established through state practice, consistency in behavior, and the belief in their legal obligation.
State Practice and the Importance of Consistency
State practice and consistent behavior among nations play a crucial role in the creation of customary international law. Customary International Law (CIL) is formed through the general acceptance of laws and rules that result from widespread, patterned behavior over time.
Through this process, unwritten instructions are developed to guide nations' interactions with items such as public health policy, treaties, war crimes trials, children's rights agreements, and more.
It is important for states to demonstrate consistency in their legal practices so they may gauge what internationally accepted acceptable norms are based off consensus amongst other stakeholders.
Consistency contributes towards forming coherent principles that represent an international common understanding of universal values, allowing states to remain equal players navigating within a typical set intuition or guideline between them all.
In this way, each state can acquire some level of recognition guaranteed legally by global community agreement apart from national governmental legislation alone. Examples include Geneva Conventions related to war-time violation codification—where all members have mutually agreed upon specific standards without repressing individual sovereignty—and collaboration on various medical initiatives surveying capitals beyond any country’s legislative jurisdiction zone like SARS-CoV-2 pandemic protocols.
Opinio Juris: The Belief in a Practice's Legal Obligation
Opinio Juris is essential in establishing a legally binding custom in customary international law, referring to the belief that a particular practice has an underlying legal obligation.
The existence of this mental state must be established by evidencing State Practice and opining on whether states truly believe they are acting under a legal duty. Generally speaking, for something to be considered as part of customary international law, there must first be evidence that certain States have acted consistently and uniformly with respect to it.
Secondly, those same States must display opinio on investiture - or ‘the how.’
Recent scholarship attempting to answer when state behavior gives rise to opinio juris has focused on emerging patterns concerning states’ attitudes towards norm adoption and implementation as indicators for ascertaining their subjective intent.
Examples such as doctrines like preferential trade agreements or resolutions from the UN Security Council provide insight into current understandings of the concept, emphatically showing that uncertainty surrounding intention should not be an impediment when interpreting rules forming wide but incomplete bodies of international conventions.
General Principles of Law Recognized by Civilized Nations
General Principles of law recognized by civilized nations are widely acknowledged as a significant source of influence in public international law. These principles touch upon various aspects of international relations, including state responsibility, human rights, and the peaceful settlement of disputes.
They originate from both domestic judicial decisions and from those of other countries’ courts, illuminating similarities between states that transcend their cultural differences.
It is also believed that custom and usage is other major factor responsible for formulating such general principles over time.
The precise content and scope of these principles have been extensively debated amongst legal scholars; they require not only consistent State practice but also the recognition by States that behavior considered to be wrongful must remain so regardless of geographical or political boundaries - i.e., opinio juris played an important role in forming these accepted norms within each country's legal system.
International tribunals refer to basic ethical rules found in textbooks or doctrinal literature when interpreting this type of law; some examples include good faith, estoppel (i.e., preventing opposition after committing to a pledge), reparation for the harm caused, respect for acquired rights, non-aggression before judgment has been rendered, etc.
The Statute Of The International Court Of Justice sets forth twenty-one rules composed solely as general principles governing all controversies heard thereon; however, it does not provide compulsory jurisdiction, which might be necessary for adjudication processes conducted elsewhere. Indeed, In many cases, debates continue concerning the best source through which more clarity may come about regarding relevant aspect(s) pertaining to the state's responsibilities when obligated based on an alleged breach related to it.
Ultimately, determining what constitutes acceptable behavior on behalf of sovereign entities under international customary law requires subjective interpretation primarily governed by precedents set decades prior, resulting in consensus throughout global communities.
Judicial Decisions and Scholarly Writings as Subsidiary Sources
International and domestic court rulings and juristic writings can provide valuable insight in terms of information and interpretation to supplement or support existing norms or treaty provisions.
The Influence of International and National Court Rulings
In international law, court rulings are essential in providing guidance and direction to states on how existing laws should be applied and interpreted. International criminal courts such as the Permanent Court of Arbitration or the International Criminal Court provide influential legal precedents for determining how treaties are meant to be enforced and upheld.
Likewise, decisions from state courts -- both national tribunals and appellate bodies –– can have a long-reaching effect across different countries by establishing precedents that are adopted into custom.
Inappropriate conduct by a country might lead its judiciary to render judgments against it that will become relevant in other cases worldwide. Examples of landmark cases include Nicaragua v United States (1986), dealing with breaches of military obligations under customary international law; ICJ North Sea Continental Shelf Cases (1969) regarding rights over territorial waters under specific agreements; Broches v Secretary-General UN Security Council (2010) which addressed immunities accorded to foreign officials; and Filártiga v Pena‑Irala (1980) concerning human rights violations recognized in international law.
The Impact of Juristic Writings on Legal Interpretation
Juristic writings and scholarly writings are an important source of international law, alongside treaties and customary rules. These often take the form of legal doctrine, commentary, opinions, literature, analysis, or theory that assist in interpreting laws and resolving disputes within the field of international law.
They have been highly influential in providing context to treaties or regulations as well as helping with the interpretation of pan-national norms. Over time, juristic writings on specific topics have established a broad consensus on particular Legal points within international communities, which is taken into account by courts when deciding cases.
In practice, Juristic works offer insight into existing customs and practices regarding a range of matters from diplomatic communication to rights protection at sea, their interpretations influencing both lawmakers in crafting new regulations and practitioners arguing before courts about her application in specific cases.
Scholars like Judge Jose Alvarez have argued that these works may not be considered authoritative sources in every instance. Yet, they remain significant factors during individual consideration since they use past precedents while weaving together applicable laws to discern the current meaning attributed to them.

Jus Cogens: The Peremptory Norms of International Law
The term 'jus cogens' originates from Latin, denoting imperative norms within the realm of general international law. These norms engender obligations that are owed not to private individuals or entities but to the international community as a whole.
These norms are characterized by their inalienability and universality, mandating their application irrespective of other prevailing circumstances. Consequently, treaties or agreements that conflict with jus cogens are rendered null and void, owing to the preemptive status of jus cogens in the fabric of international customary law.
In essence, jus cogens represent a corpus of immutable principles that no other rule can supersede. These principles form a foundational aspect of international law, reflecting fundamental values that are universally recognized and integrated into various domestic legal systems worldwide.
The codification of this concept is evident in the Vienna Convention on the Law of Treaties (VCLT) of 1969. Article 53 of the VCLT elucidates non-derogable rules as norms accepted and acknowledged by the international community, binding upon all States. These norms establish overriding principles that supersede bilateral or multilateral agreements between nations as necessary.
In summary, the acknowledgment of the primacy of jus cogens plays a pivotal role in shaping the context for contemporary legal interpretations. This includes considerations of the types of legal resolutions available today, their practical applications, the effectiveness of their implementation, and the resultant immunities.
This primacy ensures a higher degree of compliance and legitimacy in the international legal framework, significantly influencing current and future legal constructs and their practical implications at a global scale.
Conclusion: The Dynamic and Complex Nature of International Law Sources
International law, as it is understood today, is an incredibly dynamic system of rules and principles that govern the behavior of States at both the global level and within domestic borders.
Sources of international law reflect this complexity: any given legal provision can be supported by a range of sources, such as treaties between states, customary practices, or norms established over time through state practice and repeated use in international agreements or court cases.
In addition to these more traditional sources, many ongoing developments in the field are introducing new complexities in how international law is interpreted, including changes to its scope (jurisdictional) and new points on what constitutes evidence.
For example, opinions from leading academics now play a role in understanding debates around accepted general principles of law recognized by civilized nations - so-called "subsidiary" sources forming part of the primary toolkit used when interpreting international legal questions.
Other areas emphasizing even greater involvement include jus cogens standards – those peremptory norms requiring adherence by all states regardless of their stance on particular issues - creating both temporal challenges in terms of implementation plans but also carrying with them moral considerations due to their essence being considered non-negotiable human rights concerns internationally.
Ultimately, then, while much progress has been made since antiquity and existing frameworks offer good guidance for most situations encountered regarding public international law - managing relationships between actors across multiple jurisdictions remains an ever-evolving challenge dependent upon skillful navigation amongst competing sources each contributing to one unique dynamic information compilation applicable for all parties involved wherever they may reside physically or geographically speaking.
