nolo contendere

I do not wish to contend; a plea entered by a defendant.

No contest. Has the same effect as a plea of guilty as far as the criminal sentence is concerned, but the plea may not be considered an admission of guilt for any other purpose. Sometimes, a guilty plea could later be used to show fault in a lawsuit, but the plea of nolo contendere forces the plaintiff in the lawsuit to prove that the defendant committed the crime.
