Ex factis jus oritur
Principle of international law which states that law must arise from the facts
From Wikipedia, the free encyclopedia
Ex factis jus oritur (Latin: the law arises from the facts) is a principle of international law. The phrase is based on the simple notion that certain legal consequences attach to particular facts.[1] Its rival principle is ex injuria jus non oritur in which unjust acts cannot create law.[2] Both principles are utilized concomitantly in historical and contemporary international law, and applied situationally, depending on the informing circumstance.
