Lock the doors

Is a term used when putting a question (e.g. to pass a motion or amendment) to a vote. In the House eight minutes after the question has been put for the first time, the Speaker declares, "Lock the Doors" The lobby entrances are locked, and only those within the Lobbies may continue to vote. Any member who arrives after "Lock the Doors" has been stated is not allowed to vote.
