That rule starts with: "Fouled decks will be as defined by local gaming regulations and house policy."
I dunno for sure how local regs or house policy define them, but RRoP defines it thusly:
Quote:
If a card with a different color back appears during a hand, all action is void and all chips in the pot are returned to the respective bettors. If a card with a different color back is discovered in the stub, all action stands.
In this case, the extra/wrong color card was in the stub. IME this would mean all action stands and the deck would not be considered fouled.
Furthermore, it is obvious that the V saw the dealer place the "cut card", and thought they could freeroll the hand by playing it out, and only calling attention to it at the end if they were likely beaten. **** that noise.
