Duplicate bridge tournaments should be played in strict accordance with the Laws. The chief object is to obtain a higher score than other contestants whilst complying with the lawful procedures and ethical standards set out in these laws.
If the Director determines that an offender could have been aware at the time of his irregularity that it could well damage the non-offending side, he shall require the auction and play to continue (if not completed). At the conclusion of play the Director awards an adjusted score if he considers the offending side has gained an advantage through the irregularity.
