I'm not so sure. After 3♣, whatever it might mean, East could have bid 3♦, but instead bid his five-card
spade suit a second time, just to make sure his partner got the message, having heard from the explanation (UI) that he and partner were not on the same wavelength.
And if he does believe 3♣ to be an impossible call, might he not have passed it on the basis that it can only reveal a psyche... except that the UI tells him that's not the case?
I think that 3
♣ shows a big spade fit, as East intended 2
♠ as terminal. There is no reason whatsoever to assume West has psyched, no more so than if partner broke a transfer to spades with 3
♣ when "not playing transfer breaks, can't stand them pard". 3
♠ is therefore the only logical alternative (anything else would be a game try). And over 3NT, which might be something like AQxx Kx Axx Axxx, there is no alternative to 4
♠.
And what about East's final pass? He has a great hand for the auction to date, but redouble would have been more successful, so cannot be imposed. And West appears to have no UI, so he can bid what he likes, assuming there was no mannerism from East of which we have not been told. I would keep the deposit too, and leave the table result.
And FWIW, one never rules because there is "unauthorised panic". We just decide on the LAs, and "impose" the worst one that is demonstrably suggested.
I prefer to give the lawmakers credit for stating things for a reason - barmar
