IRREGULARITIES IN PROCEDURE

SECTION THREE
INSUFFICIENT BID

LAW 27 - INSUFFICIENT BID 

A. Insufficient Bid Accepted

Any insufficient bid may be accepted (treated as legal) at the option of offender's LHO. It is accepted if that player calls.

B. Insufficient Bid Not Accepted

If an insufficient bid made in rotation is not accepted, it must be corrected by the substitution of either a sufficient bid or a pass.

1. Not Conventional, and Corrected by Lowest Sufficient Bid in Same Denomination

(a) No Penalty

If both the insufficient bid and the bid substituted are incontrovertibly not conventional, and if the bid is corrected by the lowest sufficient bid in the same denomination, the auction proceeds as though the irregularity had not occurred (Law 16C2 does not apply to this situation, but see (b) following).

(b) Award of Adjusted Score

If the Director judges that the insufficient bid conveyed such information as to damage the non-offending side, he shall assign an adjusted score.

2. Conventional, or Corrected by Any Other Sufficient Bid or Pass

If either the insufficient bid or the lowest sufficient bid in the same denomination may have been conventional, or if the bid is corrected by any other sufficient bid or by a pass, (penalty) the offender's partner must pass whenever it is his turn to call (apply Law 10C1 and see Law 23 when the pass damages the non-offending side; and the lead penalties of Law 26 may apply).

3. Attempt to Correct by a Double or Redouble

If the offender attempts to substitute a double or redouble for his insufficient bid, the attempted call is cancelled; and (penalty) his 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).

C. Insufficient Bid out of Rotation

If a player makes an insufficient bid out of rotation, Law 31 applies.
