Insufficient or inadmissible call

If a player has made an insufficient bid and the next player has bid ( or passed) then the insufficenet bid is deemed to have been condoned and no plenalty.

After a player makes an insufficient bid (law 27) (of lesser rank than the last bid at the table), his LHO first receives the option to accept it, in which case no penalty is assessed.

If the bid is rejected, the offender may

(a) replace the bid with a higher legal and natural bid in the same denomination without penalty (but the information remains unauthorized to his partner).

(b) If he elects not to, or if the substituted bid would have been conventional, the offender's partner must pass to the end of auction.

An inadmissible double or redouble is canceled and must be substituted by a legal call, and the offender's partner must pass to the end of auction.
