International Law and Jurisdictional Issues

International Law and Jurisdictional Issues

The Post-Westphalian Moment

The field of International Law and Jurisdictional Issues is undergoing its most profound transformation since the Peace of Westphalia (1648) established the modern concept of territorial sovereignty. As of late 2025, traditional notions of state authority—rooted in geography and consent—are being tested by borderless digital realities, transnational crimes, climate change, evolving human rights norms, and intensified international adjudication.

Legal authority is no longer confined neatly within borders. States legislate extraterritorially, courts adjudicate transnational harms, and international tribunals increasingly confront politically sensitive disputes. At the center of this evolution lies a deceptively simple but deeply contested question:

Who has the right to decide?

Jurisdiction determines not only where a dispute is heard, but whether justice is possible at all. This article provides a comprehensive examination of international law and jurisdictional issues, tracing doctrinal foundations, contemporary challenges, and emerging trends shaping global governance.

1. Foundations of State Jurisdiction

1.1 Meaning of Jurisdiction

In international law, jurisdiction refers to a state’s lawful authority to:

• Prescribe law (legislative jurisdiction),

• Adjudicate disputes (judicial jurisdiction), and

• Enforce decisions (executive jurisdiction).

Jurisdiction flows from state sovereignty, but is constrained by international law to prevent unlawful encroachment upon other states’ authority.

1.2 The Five Traditional Bases of Jurisdiction

International law recognizes five primary jurisdictional principles:

1. Territorial Principle

A state has exclusive jurisdiction over acts occurring within its territory, including land, airspace, territorial waters, ships, and aircraft.

• Core principle of customary international law

• Includes objective territoriality, where foreign conduct produces substantial domestic effects (e.g., cybercrime, financial fraud)

2. Nationality (Active Personality) Principle

States may regulate and prosecute their nationals for conduct abroad.

• Common in criminal law, taxation, military law

• Limited in practice by extradition treaties and host-state consent

3. Passive Personality Principle

Jurisdiction based on the nationality of the victim.

• Historically controversial

• Widely accepted in terrorism, hostage-taking, and transnational violence cases

4. Protective Principle

Allows jurisdiction over foreign acts threatening vital national interests.

• Espionage, counterfeiting, cyber sabotage, terrorism

• Requires a direct and substantial effect on state security

5. Universal Jurisdiction

Permits prosecution of certain crimes regardless of:

• Place of commission, or

• Nationality of offender or victim

Applies to:

• Genocide

• Crimes against humanity

• War crimes

• Torture

• Piracy

Universal jurisdiction reflects jus cogens norms—obligations owed to the international community as a whole (erga omnes).

2. Sources of International Law and Jurisdictional Authority

Article 38 of the ICJ Statute identifies the sources from which jurisdictional claims derive:

1. Treaties and conventions (e.g., UNCLOS, Rome Statute)

2. Customary international law (state practice + opinio juris)

3. General principles of law (e.g., good faith, proportionality)

4. Judicial decisions and scholarly writings (subsidiary means)

Jurisdiction must be exercised consistently with these sources; unilateral authority cannot override binding international obligations.

3. Types of Jurisdiction

Crucial Rule:
States may legislate extraterritorially, but cannot enforce extraterritorially without consent or authorization (e.g., UNSC mandate).

4. Jurisdictional Conflicts and Overlapping Claims

4.1 Jurisdictional Collisions

Modern disputes often trigger multiple competing jurisdictional claims, leading to:

• Conflicting legal obligations

• Double jeopardy risks

• Diplomatic friction

• Forum shopping

Resolution mechanisms include:

• Treaty coordination

• Comity (mutual restraint)

• Forum non conveniens

• Mutual legal assistance

The Lotus Case (1927) famously held that states may exercise jurisdiction unless expressly prohibited—fueling modern extraterritorial assertions.

4.2 Extraterritorial Application of Domestic Laws

States increasingly extend laws beyond borders in:

• Antitrust and competition law

• Economic sanctions

• Anti-corruption (foreign bribery)

• Counter-terrorism financing

This trend raises concerns of legal imperialism and power asymmetry, particularly for developing states and global businesses.

5. Private International Law (Conflict of Laws)

Jurisdiction in private disputes involves:

5.1 Choice of Law

Determining which legal system governs a dispute.

5.2 Choice of Forum

Parties may contractually select courts or arbitration tribunals.

5.3 Recognition and Enforcement of Foreign Judgments

Depends on:

• Treaties

• Reciprocity

• Domestic statutes

Foreign judgments do not automatically apply internationally.

6. International Courts and Jurisdiction

6.1 International Court of Justice (ICJ)

• Jurisdiction is consensual

• Handles:

  • Contentious cases between states

  • Advisory opinions for UN bodies

2025 Developments:

• Advisory Opinion on Occupied Palestinian Territory (Oct 2025)

• Ongoing climate change advisory proceedings—expanding environmental obligations

6.2 International Criminal Court (ICC)

The ICC prosecutes individuals for core international crimes where national courts fail.

Jurisdiction depends on:

• Territorial state membership

• Nationality of accused

• UN Security Council referral

2025 Milestones:

• Ukraine became the 125th State Party (Jan 2025)

• Ongoing proceedings concerning Palestine, Afghanistan, and the Philippines

• Expanded reliance on universal jurisdiction by domestic courts across Europe

6.3 Specialized and Arbitral Tribunals

• WTO dispute settlement

• Investment arbitration

• ITLOS (maritime disputes)

• Environmental and human rights tribunals

These forums often bypass sovereignty sensitivities through consent-based jurisdiction.

7. Sovereign Immunity and Its Limits

7.1 Forms of Immunity

• Absolute immunity (historical)

• Restrictive immunity (modern standard):

  • Immune for sovereign acts (jure imperii)

  • No immunity for commercial acts (jure gestionis)

7.2 Human Rights and Accountability

Growing challenges to immunity in cases involving:

• Torture

• Crimes against humanity

• Enforced disappearances

2025 ICJ litigation, including Iran v. Canada, highlights tensions between immunity and justice.

8. Jurisdiction in the Digital and AI Age

8.1 Cyberspace and Borderless Harm

Challenges include:

• Attribution of cyberattacks

• Determining territorial nexus

• Enforcing judgments against anonymous actors

Classical territoriality struggles in virtual environments.

8.2 Artificial Intelligence Liability

Key unresolved questions (2025):

• Who bears responsibility for autonomous harm?

  • Developer?

  • Manufacturer?

  • Data-hosting state?

AI’s “black box” nature strains traditional fault-based legal models.

8.3 Data Protection and Internet Governance

• GDPR (EU)

• India’s Digital Personal Data Protection Act (2023)

• Rise of cyber sovereignty and “splinternet” models

States increasingly assert jurisdiction based on:

• Server location

• User nationality

• Market targeting

9. Jurisdiction, Human Rights, and Armed Conflict

9.1 Extraterritorial Human Rights Obligations

States may be liable for violations abroad where they exercise:

• Effective control over territory or persons

Applied by:

• ECtHR

• UN treaty bodies

9.2 Armed Conflict and Occupation

Jurisdiction involves:

• International humanitarian law

• Military courts

• Hybrid tribunals

Accountability remains uneven and politicized.

10. India’s Perspective on Jurisdiction

India emphasizes:

• Sovereignty and non-intervention

• Treaty incorporation before domestic enforcement

• Pragmatic tests for recognizing foreign judgments

Cases like Novartis v. Union of India affirm that treaties do not override domestic law unless legislatively adopted.

India also navigates extraterritorial risks from:

• U.S. sanctions

• Global compliance regimes

• Cyber and AI cross-border disputes

11. The Future of Jurisdiction

Key Trends

• Fragmentation of legal regimes

• Power-based jurisdictional assertions

• Expansion of universal jurisdiction

• Climate change litigation

• Digital sovereignty conflicts

Path Forward

• Harmonization of laws

• Proportional extraterritoriality

• Enhanced cooperation and MLATs

• Respect for legitimacy and fairness

Jurisdiction as the Frontline of Global Justice

International law and jurisdictional issues sit at the intersection of law, power, sovereignty, and justice. In a world where borders are porous to data, capital, conflict, and environmental harm, rigid territorial concepts are increasingly inadequate.

The credibility of international law depends on its ability to:

• Prevent impunity for grave wrongs

• Respect sovereign equality

• Adapt to technological and global realities

Jurisdiction—once a technical procedural issue—has become one of the defining challenges of twenty-first-century global governance.
