Did you know?

Latin has not been over-used in a procedural context ('ex parte' being a rare exception,) wrote a correspondent to the London Times in May 1999. Indeed, ex parte (which literally meant "on behalf [of]" in Medieval Latin) pops up quite often in legal settings. An ex parte proceeding, for example, is one that occurs at the request of and for the benefit of one party, usually without the knowledge and participation of any other party. Even when ex parte steps outside of the courtroom - to be used of an ex parte meeting, interview, chat, conversation, investigation, discussion, or contact, for example - the one-sided sense often has some sort of legal or legislative slant, referring to involvement of just one party or side in a case or dispute.
