Joint criminal enterprise (JCE) is a legal doctrine used in criminal law to hold multiple individuals accountable for a crime committed together. Under this concept, all participants in a criminal plan can be charged for the actions of one member, as long as those actions were foreseeable and part of the shared objective. This principle is often applied in cases involving organized crime or group violence, where individuals may have different roles but share a common goal. JCE helps ensure that all parties involved in a crime are held responsible, promoting accountability within criminal activities.
