25. PLAYING WHEN NOT ENTITLED TO DO SO

1. STRIKER If the striker plays a stroke when not entitled to play and the error is discovered before the first stroke of the adversary's next turn, the error is rectified and the turn ends.
2. ADVERSARY If the adversary starts his turn prematurely (see Law 4(e)) and the error is discovered before the end of the striker's turn, the error is rectified and the adversary restarts his turn correctly after the striker's turn has ended.
