Law 31 is clear about this: When the offender has bid at his partner’s turn to call, or at his LHO’s turn to call if the offender has not previously called, offender’s partner must pass whenever it is his turn to call (see Law 23 when the pass damages the non-offending side), and the lead penalties of Law 26 may apply. In this case the pass damaged the non offending side, as with 2 aces and 11 pts, the player could choose another bid instead of pass over 3NT.
