It's not, at least according to the FIDE Laws of Chess [http://www.fide.com/component/handbook/?id=124&view=article]:
Article 1 said:
The game of chess is played between two opponents who move their pieces alternately on a square board called a 'chessboard'. The player with the white pieces commences the game. A player is said to 'have the move', when his opponent's move has been 'made'. (See Article 6.7)
It's a relatively recent rule in terms of chess history, though. It wasn't really codified until 1889 by Wilhelm Steinitz (the first world chess champion).
