"Audi Alteram Partem" - It's a legal principle which means "hear the other side", meaning that no judgement should be made against somebody without giving them an opportunity to be heard and present their case.
The significance of this Latin maxim in English is:
"Do not have the government of an equal among equals."
This is one of the principles of international law, which speaks of the equality of states as equal subjects of international relations.
The significance of this maxim is that it gives the right of every state, regardless of its size or other characteristics, to protect its international legal subjectivity, its equality and independence, in accordance with the UN Charter.
