When the solution of a case submitted to the Criminal Division appears to be imperative, the First President or the President of the Criminal Division may decide to have the case heard by a panel of three judges. This panel may defer consideration of the case to the hearing of the chamber at the request of one of the parties; deferral is automatic if one of the judges making up the restricted panel so requests. The panel declares inadmissible appeals or appeals that are not based on a serious ground of cassation.
