Ex injuria jus non oritur
Principle of international law which states that unjust acts cannot be used to create law
Ex injuria jus non oritur (Latin for "law (or right) does not arise from injustice") is a principle of international law.[1] The phrase implies that "illegal acts do not create law".[2] Its rival principle is ex factis jus oritur, in which the existence of facts creates law.[3]
