E/W appeal, and it's yours...
[pompous]
As a member of the appeals committee, I ask the TD where (the german translation of) "irrational, wild or gambling" occurs in the Laws. Then I would point out that a similar phrase appears in Law 12c1b, but that law does not stop the score for the offending side from being adjusted.

Then we need to sort out what the EW agreement is: I do not accept the statement "East got the incorrect explanation" without further investigation. If 4NT can be any two suits, how does advancer act, and how does 4NT bidder then show his suits? Have they ever bid (4
♥)-4NT with spades and a minor?
We might find that East was given the correct explanation and would still bid 5
♦, but West has been misinformed. With the correct explanation, West might bid 5
♠ (North still doubles) and if this scores any better than 5
♥X then an adjustment (for both sides) would be in order.
We might find that East was not given the correct explanation and would not have bid 5
♦ with the correct explanation. I agree with the TD that 5
♦ was wild or gambling and adjust the score to the result in 5
♣, for NS only. EW keep their table score (since their damage was due entirely to the SEWoG action).
We might find that the correct explanation is no agreement "usually the minors but we have not discussed whether it might be a stronger two-suiter with spades and a minor" or "no agreement: general bridge knowledge tells us that advancer will usually bid a minor, to play". With such an explanation, East might still bid 5
♦ expecting West to be able to work it out. We might then adjust to a proportion of the result in 5
♣ and a proportion of the result of East bidding 5
♦, again for NS only. EW would again keep their table score.
