The right question, it would seem, is to ask "What is your agreement to open with the same hand with the clubs and spades transposed?" If the answer is 2C, then this could be argued to be an illegal agreement, although the second best break is probably Qxxx opposite T or Txxx opposite Q, when there are 8 clear-cut tricks, so it would seem to still be legal. [....]
Importantly, in suits other than the suit opened, there is no requirement whatsoever for 8 clear-cut tricks. Of course there might be MI if one states "8 playing tricks in a suit or strong balanced", although that does not use the phrase clear-cut tricks, and this is certainly 8 "playing tricks" by all methods of evaluation that I have found. My view is that the adjustment was just a mistake, and should be corrected by the EBU as director error.
Paul, the players you are trying to defend are trying to use a 2
♣ opener to show a hand with eight playing tricks in any suit, they are not trying to make distinctions between hands with one particular suit rather than another, so this is irrelevant. If they made such a distinction between the suits their explanation and convention card would attest to this. Of course, there are clever ways of getting round the regulation by having different rules for clubs than for any other suit, but your players have no interest in adopting this sort of agreement, they just want to play "Benjy".

The correct question is "Did you and your partner have an agreement to open 2C on this hand?" The answer to that would have been "No". Playing Benjy Acol many people would consider that the "correct" opening on this hand is 2C. If one did not play SAT, but had agreed to play Benjy, I would open 2C and rebid 4S. That is perfectly ok, but it is illegal to have an agreement to open 2C on this hand!
I agree that the way TDs question players in this situation is tricky, and I take Nigel's point that devious players could prepare answers that would get them off the hook which would catch honest players, but I would ask both members of the partnership what they would open on this hand. If either or both admitted that they would routinely open it 2
♣ (as you admit you would do) I would rule that that is part of their methods and therefore of their (implicit) agreements and award an adjusted score if I considered the opponents had been "damaged" (in this case, if they had scored worse than +3 IMPs on the board).
