Ok, so no-one except me cares whether there was an infraction.
The West hand is the sort of hand that puzzles poorer players. They have been told that bidding the opponent's suit is artificial. Sure, they know they have a reasonable hand but they 'cannot' bid their long suit. Furthermore, one of the mistakes that poor players [and fair players, to my surprise] do is to pass after 1X dbl 1Y with fair and reasonable hands. So while I do not approve of the pass over 1
♠ I can understand it [and my approval is irrelevant anyway

].
But players with fair hands do worry and there is a tendency to bid later. So, while it may be difficult to poll suitable players, I have the feeling that pass over 2
♥ is not an LA. Of course, the choice of 3
♣ is poor: 3
♦ seems normal, but again, this player probably neither considered it nor thinks partner would understand it as diamonds [and he may be right]. So for this level of player I think 3
♣ might be considered
evident. No infraction, no adjustment, no worries.
Much of the discussion has been about the defence to 4
♠. Of course if the hand is really as shown it must have been dreadful for 4
♠ to make, and probably bad enough to deny redress for N/S. Bu that does not mean you do not adjust for E/W!
While I do not think pass over 2
♥ is an LA, I expect some of you do. If so, where do we go? Well, one view is that 4
♠ will be reached automatically. I am less confident of this than others. When 2
♥ gets round to the doubler, he might bid 2
♠: would partner pass? Do something silly? What happens when opener raises?
Remember this is the ACBL. For the offending side we assign the most unfavourable result that was possible: are you sure that they would get to 4
♠ a high enough proportion of the time for this to be the case? You do not think that with a pair that clearly has little idea what it is doing and a spade bid from the opposition, that they will always get to this bad game? I am unconvinced.
I think that several of the responses to this thread are along the lines of what would happen, or is most likely to happen, and so on. But that is not what we do for rulings: we look at all the possibilities, and then pick the one that fits into Law 12C1E's standards, which is often a result that is not particularly likely.
