I have decided to delete a lot of threads unread, so if this or my other query has been discussed, please let me know.

I was called the table at Brighton after the following sequence. Actually, I cannot remember the sequence for certain, but it does not matter, I can remember the bits that matter.
When I was called, East had led the ♠A and dummy had appeared.
Basically, what was said was as follows:
North: West hit the table with the flat of his hand clearly indicating he was passing.
East: I thought partner had passed, and when he said something I turned my lead face up.
South: What's the problem?
West: What I said was "Why are you leading when I am declarer?".
It was clear that West had not seen the 2♦ bid. Furthermore he showed me that he had written 1NT by West on his score-card. He also stated that he never made the final pass of an auction in any other way but by putting out a pass card.
How do you rule?
In a few days I shall tell you how I ruled and what happened next.
