INADMISSIBLE CALLS

LAW 37 - ACTION VIOLATING OBLIGATION TO PASS 

A bid, double or redouble by a player who is required by Law to pass is cancelled, and (penalty) each member of the offending side must pass whenever it becomes his turn to call (see Law 23 when the pass damages the non-offending side). The lead penalties of Law 26 may apply. (If offender's LHO calls, see Law 35B.)
