In a recent teams of four competition the folowing incident happened.
When first played North played in 4S making the contract. When the board was played the other way round North again bid 4S but when dummy went down it was obvious that something was wrong. Both East and North had the KH. It was then realised that North had picked up the cards from a different board. One way North had bid and made 4S and when played the other way the board was fouled. Surely North must be penalised for this infraction? What is the correct way to score it?

The appropriate law is 17D. North made a call with the wrong hand, and his partner has subsequently called, so an artificial adjusted score is given. Since North was (presumably) entirely at fault, his team will normally get -3 IMPs and the other team +3 IMPs. However, if the result at the other table was good for the other team (so +3 may not be sufficient compensation) an assigned adjusted score should be given instead (law 86D).

If the hand North was looking at was from a board they have yet to play (but the other table has played) then the TD might allow the board to be played provided the player repeats the call(s) that he made on the hand originally (17D3), but otherwise there will be a second adjusted score.
