Glomar response
In United States law, the term Glomar response, also known as Glomarization or Glomar denial, means to respond evasively to a question with the phrase "neither confirm nor deny" (NCND). For example, in response to a request for police reports relating to a certain person, the police agency may respond: "We can neither confirm nor deny that our agency has any records matching your request." The phrase was notably used to respond to requests for information about the Glomar Explorer.
