When an irregularity has occurred, any player - except dummy as restricted by Law 43 - may draw attention to it and give or obtain information as to the law applicable to it. The fact that a player draws attention to an irregularity committed by his side does not affect the rights of the opponents.

After attention has been drawn to an irregularity, no player should call or play until all questions in regard to the assessment of a penalty have been determined. Premature correction of an irregularity on the part of the offender may subject him to further penalty (see Law 26).

 

A penalty may not be imposed until the nature of the irregularity to be penalized has been determined and the applicable penalty has been clearly stated; but a penalty once paid, or any decision agreed and acted upon by the players, stands and should not, except by agreement of all four players, be corrected even though at some later time it may be judged incorrect.

The right to penalize an offense is forfeited if

(a) both members of the non-offending side waive the penalty.

(b) a member of the non-offending side calls (Law 34) or plays (Law 60) after an irregularity committed by his RHO.

A player may be subject to penalty if he conveys information to his partner other than by a legal call or play.

If a player conveys information to his partner by means of a remark or question or by unmistakable hesitation or unwonted speed, special emphasis, tone, gesture, movement, mannerism or any other action that suggests a call, lead or plan of play; and if attention is drawn to the offense immediately, when the offending side has profited through the doubtful call or play so suggested, it should, in conformance with Proprieties 1, redress any damage done to the non-offending side.
