Didn't North just give up 1400 for no reason at all? Pulling the penalty double does not appear to be suggested by the explanation (either the one that describes their agreement or their hand).
In any case, if West has no UI then they are free to do what they like. I believe there is even a specific clause in the alert regulations that states that tendency to forget is not to be part of the explanation.
Table result stands.
I agree that the result should stand.
North can't be sure that that the Naymats 4
♦ was bid by mistake.
With this said and done, South is known to have a hand that is willing to sign off in 4
♥.
I don't think that the decision to pull the penalty double was caused by the infraction. It was simply a poor decision.
One interesting question that hasn't been raised:
Absent the pass of 4
♦, the 5
♦ bid would be a lead directing raise to 5
♠.
