protective principle
Quick Summary
The protective principle in international law allows a state to assert jurisdiction when an alien commits an act abroad that is prejudicial to that state's interests. This principle is distinct from the passive personality principle, which applies when an act harms a state's citizens. The protective principle is included in various conventions, such as those concerning hostages, aircraft hijacking, and the safety of United Nations personnel.1
In environmental law, the precautionary principle guides action when there is a strong suspicion of environmentally harmful consequences, even without full scientific certainty. It advocates for controlling activities that may cause serious or irreversible damage rather than waiting for conclusive evidence. This principle has been adopted by international bodies and invoked in disputes concerning environmental protection.2
