West is declarer in a spade contract. South leads the Ace of clubs, out of turn at trick one. The director is called to the table and options are explained. West refuses a club lead. North leads a diamond, South picks up the club Ace and dummy is tabled, showing 4 clubs to the Queen. West wins the diamond lead in dummy and takes a losing spade finesse. North now plays the King of clubs from K,x, continues with a small club, won by partner's Ace and then ruffs the club return. The club King would never be led unless North knows partner holds the Ace. The director is called to the table and makes no adjustment. Is this the correct ruling?

All non-vul. Dealer W. Auction: P,1H,X,2H,2S,all pass. North holds Axx, AQxxx, J10x, Kx. East holds QJxx, Kx, Axx, Q10xx. Experienced players.
Can't put in "x" for spots, so the actual spots may have been different. I doubt that matters.
Director is called for an opening lead out of turn. Law 54 applies. The director explains the five options. West, presumed declarer, chooses to play the hand, and to refuse the LOOT. The
♣A becomes a MPC (Law 50) and North is on lead. In particular, says Law 54D, Law 50D applies. Director turns his book to Law 50. Declarer elects to prohibit the lead of a club. Per Law 50D2{a}, the
♣A "is no longer a penalty card" and is picked up. Now the director should, but at the table did not, inform North that knowledge that South has the
♣A is UI to him, and that if the director judges, after the play, "that the exposed card conveyed such information as to damage the non-offending side he shall award an adjusted score" (Laws 50E2&3). North leads a diamond at trick one, later regains the lead, and leads the
♣K. As the director, I would almost certainly judge in this case "that the exposed card conveyed such information as to damage the non-offending side" and so would award an adjusted score. Since I apparently am not aware of my error, but assuming I am now somehow aware of Law 50E3, I would adjust to whatever I think West can make if North leads something other than a club at trick three. This being the ACBL, I would apply Law 12C1{e}, which may result in a split score. However, I have made an error in not explaining North's obligation regarding UI. So if I cannot find "a rectification that will allow the board to be scored normally"*, I should treat NS as non-offending (Law 82C), which means they get "the most favorable that was likely" for their side, instead of "the most unfavorable result that was at all probable" (Law 12C1{e}). EW gets the same result they already got. I am not sure how this would be handled in a 12C1{c} (i.e., weighted score) jurisdiction. Perhaps a change in the weightings for the original OS, perhaps no change at all. Perhaps someone from such a jurisdiction can weigh in on this point.
The fact that there are situations (mostly, I think, where the director is not called when he should be) where I would "rule against" a contestant who may have been ignorant of the law when he violated it is not relevant to the ruling in this case.
One other thing: Lamford's hypothetical hand upthread demonstrates why North's lead of the
♣K must be rectified.
* In this case, the question is whether the original assigned adjusted score constitutes "normal" scoring, or whether "normal" scoring would have to result from actual play. At the moment I'm thinking the latter, but I don't have a clear basis in law for that (or for the former position either) so I'm open to discussion on that point. In the actual OP case, there
was no adjusted score, so the director in fact made two errors: he didn't explain the ramifications of UI under Law 50E, and he didn't adjust the score under Law 50E3. Oh, and I suppose it's remotely possible that with full knowledge of all four hands the director might judge that the UI did
not affect the result. Remotely because while I can see how NS might get two club tricks later, I don't see how they're going to get a club ruff if declarer has time to draw the rest of the trump.
