SECTION FOUR
CALL OUT OF ROTATION

LAW 31 - BID OUT OF ROTATION 

When a player has bid out of rotation (and the bid is cancelled, as the option to accept the bid has not been exercised - see Law 29):

A. RHO's Turn

When the offender has bid (or has passed partner's call when it is a convention, in which case section A2b applies) at his RHO's turn to call, then:

1. RHO Passes

If that opponent passes, offender must repeat the call out of rotation, and when that call is legal there is no penalty.

2. RHO Acts

If that opponent makes a legal  bid, double or redouble, offender may make any legal call; when this call

(a) Repeats Denomination

repeats the denomination of his bid out of rotation, (penalty) offender's partner must pass when next it is his turn to call (see Law 23).

(b) Does Not Repeat Denomination

does not repeat the denomination of his bid out of rotation, the lead penalties of Law 26 may apply, and (penalty) offender's partner must pass when ever it is his turn to call (see Law 23).

B. Partner's or LHO's Turn

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  , (penalty) 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.

Later bids at LHO's turn to call are treated as changes of call, and Law 25 applies.
