A plea where a defendant does not admit or deny the charges in criminal court is called a nolo contendere or no contest plea, often entered as part of a plea bargain.
Step-by-step explanation:
The type of plea where a defendant in a criminal court does not admit or deny the charges is known as a nolo contendere or no contest plea. This plea means that while the defendant does not admit guilt, they also do not dispute the charges and allow a judgment to be entered against them. This type of plea is often entered as part of a plea bargain, where the defendant agrees to accept a lesser charge or a lighter punishment in exchange for their plea, thereby avoiding a trial.
