Legal Definitions - exceptio plurium concubentium defense

Definition: Exceptio plurium concubentium defense is a legal defense that claims that the plaintiff cannot prove that they were the only sexual partner of the defendant at the time of the alleged incident.

Example: In a case of paternity, the defendant may use the exceptio plurium concubentium defense to argue that the plaintiff cannot prove that they are the only possible father of the child.

This defense is based on the idea that if there were multiple sexual partners, it is impossible to determine who is responsible for the alleged harm. Therefore, the defendant cannot be held solely responsible.
