Assuming North thought his double showed spades and a double showing spades was not alertable, then North has unauthorised information that suggests 4♠ over passing 3NT.

The TD will need to consult to determine if there are logical alternatives to 4♠. If Pass is a logical alternative then possible outcomes are 3NT+2 and 3NT+3 and the TD needs to award one or the other or a weighting of the two, depending on whether Law 12C1c is applicable.

As a side hypothetical.... what if 2♦ was played as many in NA do, promising an A, K, or better.

It doesn't seem to me that Pass is an LA. The double presumably promised a 5-card suit, and he has 7; who wouldn't think that's worth bidding again, even with those sucky spot cards?

The only reason that hand was even worth the strong opening is because of that 7-card suit. But responder is probably expecting opener to have full values; he'd bid 3NT with just an ace. The North hand isn't strong enough for that; there are two Kx suits, and there's no reason to expect partner to provide stoppers in both of them.

hmmm, is Kx not a stopper by itself ??

I'm with Robin. There are too many "if"s as to be able to give a straight ruling.

Not when the lead is going through it.

That hand would be fine as declarer in NT, but it's very risky to have it as dummy in this auction.
