IADAA: the (missing) Spanish element

I recently noted that an Egyptian coffin seized at Miami had been handed over to the Egyptian authorities. On February 24, 2010 the Barcelona gallery was listed as a member of the International Association of Dealers in Ancient Art (IADAA). So, in a space of a couple of weeks, all trace of the membership had been removed. 

I was intrigued and sent three separate emails to the officers of the IADAA: Gordian Weber (chairman), Serena Cooper (organisation and membership issues), and Dr Ursula Kampmann (Cultural Property Issues and Public Relations).

I have not received any clarification.

What does this silence imply about the resignation? Or should we read this as a removal? Does this absence reflect the rigorous ethical standards of the IADAA?

If - and it is a big IF - there has been some unusual trading activity by the Barcelona galerista, what has made the IADAA act in this way?
