What is the term for the entry made on record by a prosecutor or plaintiff indicating they will not pursue further legal action?

The term that describes the entry made by a prosecutor or plaintiff indicating they will not pursue further legal action is "Nolo Prosequi." This Latin term translates to "not to wish to prosecute." By filing a Nolo Prosequi, the prosecutor is formally notifying the court that they are voluntarily dismissing the charges against a defendant or that they will not proceed with the case for specific reasons. This action reflects the discretion of the prosecutor, based on factors such as insufficient evidence, changes in circumstances, or considerations of justice.

Dismissal generally refers to the termination of a case, but it can occur for various reasons and may not always imply the prosecutor's voluntary action. Withdrawal may refer to a similar concept, but it is not the standard legal term used in this context. An appeal involves seeking a higher court’s review of a lower court’s decision, which is not relevant to the situation of deciding not to pursue a case.
