Delaware Code
Subchapter VIII. Texas Hold’em
§ 1546. Misdeal.

(a) A card that is meant to be dealt face downward but is dealt face upward or flashed as it is dealt so that a player might know its identity or a card that is dealt off the table is dead. An exposed card meant to be dealt face downward must be replaced.
(b) In Texas Hold'em Poker games, if the flop is dealt prematurely or contains too many cards, the community cards are mixed with the remainder of the deck, which is then reshuffled, cut by the dealer and a new flop is dealt without burning a card. If the fourth community card is dealt prematurely, it is taken out of play for that round. The dealer will burn and turn what would have been the fifth community card in its place. After betting is completed, the dealer will place the premature fourth community card in the remainder of the deck, which is then reshuffled, cut by the dealer who then burns and deals the final community card. If the premature card is dealt on the fifth card, the deck is reshuffled and dealt in the same manner.
(c) A misdeal causes all of the cards to be returned to the dealer for a redeal. A misdeal may not be called once action has occurred.
