This is a case that came up only last week somewhere in Holland. I don't know anything about the players or their systems, but the bidding, especially West's, is painful to see, but that's not the question.
Neither N's 1♦ nor S's 1♥ was alerted. Though allowed, these calls are unusual given the strength of the hands and therefore alertable, assuming a (silent) agreement, which I think is probable. I don't believe in accidental deviations when made by both players on the same hand. EW claim to be damaged by the missing alerts.
I think that W is mainly to blame. E's first double makes clear that he has opening values, after a very weak response by W the 2NT by E makes clear that his hand is stronger than 15...17 HCP, because he would otherwise have bid 1NT in the first round, as is their agreement. W didn't believe his partner, but NS instead, assuming that they had far more points than they in reality had. I strongly believe that 'Trust your partner' is the most important rule in bridge, W broke that rule and his bids are seriously idiotic. I consider this to be an extremely serious error and would therefore not adjust, notwithstanding the infractions by NS. Maybe they deserve a score of 3NT+1 for EW, but EW keep their result (2NT+2).
