Things like "lying" and "bluffing" are really the rightful subject of house rules.

The rules of the original games don't encourage lying, but they don't always go out of their way to prevent it either, given their designers' knowledge that different players have different "standards."

In order to prevent such lying in home games, the players should agree on house rules to prevent/penalize it. One such rule is could be that if someone is caught in a lie, s/he automatically loses the game, which is a bit harsh. A lesser but still substantial penalty is that if the person lied about not having the card, s/he should not be allowed to play it even though in possession of it.
