as everyone has said, the hand is dead when the cards get mucked and when the cards pass the betting line, a card protector is fine if the cards are visible and not protected by a persons hand. i hate it when i think everyone has folded, i say is that it, silence, muck then someone says hang on, move there hands and still have cards in front of them and win the pot, i usually want to get up on the table and cause a riot but usually a quick word to the offending player usually does the trick.
nothing you can do if the tourney director has given a ruling(questionable though) and play the next hand and forget about it whilst playing
oh my god, durex split!!! now you have me worried
