Answer:
Are you referring to a morality clause in a contract? It basically is a clause that says that if one of the parties does something offensive to public standards of morality, then the other person has the right to void the contract. So, for example, a model might sign a contract with an advertiser with a morality clause in it, and if she then sacrifices a goat while naked at noon in Times Square, the advertiser has the right to cancel the remainder of the contract to avoid being associated with naked goat-sacrifice.
