International obligations arise through recognized legal sources.
Different sources create different evidentiary and interpretive questions.
Combine general practice with a sense of legal obligation.
Repeated behavior alone is not enough; opinio juris matters to customary-law claims.
Draw on principles recognized across legal systems.
These can fill gaps where treaty and custom do not resolve a legal issue.
Influence behavior without full binding force.
Declarations and guidelines can shape expectations and later legal development.
Authority depends on who may regulate whom and where.
Territoriality remains central but nationality, protective interests and universal jurisdiction extend the analysis.
Regulate conduct within state boundaries.
Territorial jurisdiction is foundational but complicated by digital and transboundary activity.
Regulate nationals beyond territory in some contexts.
Personal jurisdiction links legal authority to membership rather than location alone.
Project law beyond borders under specified bases.
Competing jurisdiction claims can produce conflict and comity problems.
Limit otherwise valid jurisdiction.
State and diplomatic immunities reflect sovereign equality and functional protection.
Wrongful acts can generate duties of cessation and reparation.
Responsibility depends on attribution, breach and applicable defenses.
Connect conduct to a state or international actor.
Private conduct is not automatically state conduct without relevant legal links.
Compare conduct with the applicable obligation.
Timing, scope and exceptions determine whether conduct violates the rule.
Permit limited responsive action under conditions.
Countermeasures are constrained and distinct from punishment.
Address injury caused by wrongful conduct.
Restitution, compensation and satisfaction serve different remedial functions.
International institutions interpret, coordinate and sometimes adjudicate law.
Enforcement is fragmented and varies sharply across subject areas.
Resolve disputes when jurisdiction exists.
International adjudication generally depends on consent or treaty-based authority.
Coordinate rulemaking and implementation.
Institutions can monitor, standardize and facilitate collective action.
Apply or interpret international law internally.
The domestic effect of international law depends on constitutional and statutory arrangements.
Explain why actors follow international rules.
Reciprocity, reputation, domestic politics, legitimacy and coercive leverage can all contribute.
International law operates without a centralized world government. Its force comes from treaties, custom, institutions, domestic incorporation, reciprocity, legitimacy and material consequences rather than one universal enforcement mechanism.
