Yes, but nevertheless SB was in a worse position than he would have been if the COOT did not happen, even before he called. If he bids, this is technically an opening bid, but semantically an overcall. But there are usually no methods agreed for this kind of overcall. A nice idea for example would be to bid 1
♠, showing takeout of
♠. But how can he know that partner would interpret it like this? Would double by North now be a comparable call or not? And if North passes, there is some risk that tt on the East seat might pass, too, without bothering to consider the auction carefully? If West bids 1nt, does this promise a
♠ stopper or not?
There is a lot of potential damage for E/W from the start, and the law refuses to compensate for this in case of a non-comparable call, other than silencing South for one round (not clear which side will find this to be helpful).
However, I agree with the majority here that Law 12B1 is only descriptive and does not authorize the TD do make an adjustment. Law 12A1 grants an authorization, but only if the infraction in question is not covered by any Law. This is not the case here - BOOT in handled by Law 31, and this mentions explicitly the Laws 16C, 26B and 72C. This means that Law 23C applies only in case of a comparable call. We see the same principle implemented in Law 27 (insufficient bid), so this is wanted by the lawmakers and not an accidental effect.
