This confirms that they have indeed made up their own screen regulation.
They prevent the other side of the screen from inspecting the complete auction before the opening lead, a possibility that is explicitly required both by law and by official regulation.
And North and East did in fact signal to South and West that they had completed the auction by passing, so I see no legal alternative to ruling that the contract was 1NT undoubled. (The actual hands make no difference for my opinion here).

Under which law are you removing North's double? It was clearly made according to the EBL regulations:
Quote
With screens in use a call is considered 'made' when placed on the tray and released.
But although the double was placed on the tray it was never "released"!
How North fumbled with the tray is not important, what counts is what was "released" to the other side of the screen. Here the only message "released" was that the auction had ended, and the only way this could happen is by North completing the auction with a pass.

And as asked previously, would you still insist on the contract being 1NT undoubled if it made 7+ tricks and therefore North gained through their infraction? You seem to me to be on very shaky legal ground here pran.
East was party to the infraction by not insisting that the tray should be pushed all the way through the screen according to regulation, so yes, I would not let him gain from a doubled contract.
However, I
might take this alleged gain for the North/South side into consideration when assessing a PP on North..
