The law relating to state jurisdiction under international law governs a state's legal authority to regulate conduct and enforce laws. Jurisdiction reflects a state’s sovereign power, and is crucial for law enforcement, governance, and dispute resolution. International law sets boundaries on how and when states can exercise jurisdiction, especially when actions or individuals are linked to more than one state.
Types of Jurisdiction Recognized in International Law
Territorial Jurisdiction
States have full jurisdiction over acts, persons, and property within their territory. This is the most widely accepted and undisputed form of jurisdiction.
Subjective territoriality: Jurisdiction over acts initiated within the state's territory.
Objective territoriality: Jurisdiction over acts that produce effects within the state, even if initiated elsewhere.
Nationality Principle (Personal Jurisdiction)
A state may assert jurisdiction over its nationals, regardless of where they are in the world. This applies to both natural and legal persons.
Protective Principle
A state may exercise jurisdiction over actions abroad that threaten its national security or core interests, even if the person involved is a foreign national.
Universality Principle
States may claim jurisdiction over certain crimes that are considered so serious that they harm the international community as a whole (e.g., piracy, genocide, war crimes, human trafficking), regardless of where the crime occurred or the nationality involved.
Passive Personality Principle
A state can assert jurisdiction over crimes committed abroad if the victim is one of its nationals, especially in cases involving terrorism or violent crimes.
Prescriptive vs. Enforcement Jurisdiction
Prescriptive Jurisdiction
A state's authority to make laws and regulations.
Enforcement Jurisdiction
A state's authority to enforce its laws through its police or judicial systems.
Note: A state generally cannot enforce its laws within the territory of another state without consent.
Jurisdictional Conflicts and Cooperation
Extradition treaties, mutual legal assistance agreements, and international courts help resolve jurisdictional disputes.
The principle of non-intervention limits unjustified extraterritorial enforcement.
States may coordinate through Interpol or UN bodies to respect jurisdictional boundaries while pursuing justice.
Limitations and Immunities
State Immunity
Under the principle of sovereign equality, one state cannot be subject to the jurisdiction of another state's courts in most cases.
Diplomatic Immunity
Diplomats and certain international officials are protected from host state jurisdiction under the Vienna Convention.
Act of State Doctrine
Courts generally refrain from judging the validity of public acts committed by a recognized foreign sovereign within its own territory.
Example
Suppose a national of Country A commits a cybercrime from abroad that impacts financial institutions in Country B.
Country B may assert objective territorial jurisdiction due to the effects of the crime.
Country A may assert nationality-based jurisdiction since the offender is its citizen.
If the crime threatens critical infrastructure, Country B may also invoke the protective principle.
If both countries agree, they may collaborate through extradition or joint investigation to prosecute the offender while respecting each other’s jurisdiction.
