no contest

1 a decision by the referee to declare a boxing match invalid on the grounds that one or both of the boxers are not making serious efforts.

2 a competition, comparison, or choice of which the outcome is a foregone conclusion.

☞ This expression is mainly found in the USA, and is perhaps influenced by the plea of nolo contendere (I do not wish to contend) in US law, meaning that the defendant in a criminal prosecution accepts conviction but does not admit guilt.
