Ex injuria jus non oritur
Principle of international law which states that unjust acts cannot be used to create law / From Wikipedia, the free encyclopedia
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]
