Upon or from one side only; one-sided; partial; as, an ex parte statement.
A judicial proceeding, order, injunction, etc. is said to be EX PARTE when it is taken or granted at the instance and for the benefit of one party only, and without notice to or contestation by any person adversely interested. The SEC almost always makes all hearings public and most usually gives general notice of any public hearings, but it has the authority to order otherwise.
Latin: "for one party only". Ex parte refers to those proceedings where one of the parties did not received notice and, therefore, is neither present nor represented. The choice not to attend, after notification, does not constitute an ex parte proceeding. Some jurisdictions expand the definition to include any proceeding that goes undefended, even though proper notice has been given.
