Airport authority. An airport authority is an independent entity charged with the operation and oversight of an airport or group of airports. These authorities are often governed by a group of airport commissioners, who are appointed to lead the authority by a government official. When the authority of an entity encompasses more than just the airports in an area, harbor and rail facilities for example, the entity may be referred to as a port authority. In Canada, airport authorities usually refer to private (not government owned or affiliated) not-for-profit companies that are established to manage a city's commercial airports.
Adverse authority. Adverse authority or adverse controlling authority, in United States law, is some controlling authority based on a legal decision and opposed to the position of an attorney in a case before the court. The attorney is under an ethical obligation to disclose that legal decision, which is an adverse authority, to the court.
