I actually gave an adjusted score based on some proportion of 3♣(W)-1 and some proportion of 3NT(E/W)-2, assuming that East would still bid 3♦ some of the time. I agree now that I shouldn't have included that, and should have included some of 2♠(N)-1. Thank you, Campboy et al.
I'm still not convinced I should have done anything at all, as the players were quite happy to rule on the insufficient bid themselves in the first instance. Is the fact that all players had a duty to call the director sufficient to regard EW as partly at fault for not calling the TD? Would it depend on the experience of the players?
To some extent, locally here in club bridge, if both pairs knew enough of the rules and there was (as there usually is) a playing director, getting as far as "Do you accept it" - "No" - "I'll correct it to 3
♦ as both bids are natural" saves a lot of time even if technically incorrect procedure, director would be called every time if it was not this simple a correction.
In an event with a non playing director, or where one pair is unsure, he should certainly be called and usually will be, although I'm not sure either side should lose all rights for not doing so as it is one that would require a call back at the end anyway, and I don't think director intervention at the proper time would have changed anything.
