Thanks again bluejak for the response.
If I may impose one last time on this topic for your time and patience.
The "revoke" in the slam was not noted during the hand or the course of the round or at the scoring of the round or at the end of the match.
It was "noticed" after the teams had gone home. The opposition got hold of one of our players and "ran through" the hand over the phone with them, and got him to agree that he or his partner must have revoked.
I personally feel a little bit aggrieved at this situation as the chap in question wouldn't say "boo to a goose". Also, to expect someone to mentally recall a hand literally hours after it was played is ridiculous. ~ I know 1 person that could do that with any accuracy without special attention having been drawn to it at the time. Plus, the situation totally ignores the possibility of bad play from their players. As I said we are in a low division, lol.
This phone call had to have taken place after the 30 minute time limit had elapsed as our team were on our way home when it elapsed ~ so presumably it was for the adjudicator to intercede as an unbiased third-party and take statements rather than rely on the "word" of one team?
Another point of contention is the 30 minute period. We have no record of when the score was signed, we have no recollection of the time the score sheet was signed, we have no indication from anybody of the time that their appeal was lodged or the time that they assert the score sheet was signed.
When we appealed against the score adjustment the appeals committee found as facts that i) The revoke had taken place. ii) The appeal was made within 30 minutes of the end of the match.
From the laws you mention I cannot find one that refers to resurrecting a hand that had been played during a match ~ that was NOT subject to an appeal or adjudication during any part of the match, and the results and scores were agreed on and correctly recorded.
I would be grateful of your opinion on this situation and I promise that I won't add another question.
