If the facts are as Wayne outlined, I think north is the culprit not south. Nobody has managed as yet to come up with a hand for north which is consistent with anything other than a weak two in ♠. The top-heavy 6-6 in the reds is closer to a game-force than a weak two.
I don't think it is necessary to come up with a hand. Players make bad bids often. Some of those are in auctions where it is impossible to come up with a hand consistent with the bidding that would make the given call.
Mistake earlier inconsistent call now.
The problem is if you don't think there is a weak two in hearts consistent with 4♠ now whether you think the mistake is that partner has told you the wrong major on their second call or whether the mistake was at their first call or their last call.
Its easy to say afterwards that this is an obvious correction but is there really no reason why the mistake couldn't be opening a hand unsuitable for a weak two or having a rush of blood to the head and making a move after partner has signed off?
