From what I remember from Shawn's book (yes, I read it...read almost all of the WWE books, in fact...such a mark), he pretty much admits to being in on it. After the decision had been made by Vince and the ruling power structure. He claims he was just being a company man and following Vince's orders. He happened to agree with the reasons behind taking the belt off of Brett, too. So he's definitely not an innocent bystander in any of this. But when it comes down to it, he was being a company man for the WWE and didn't want to see Brett possibly show up on WCW tv with the title and drop it in the trash or anything like that. Vince didn't want any of the backlash to land upon Shawn or Hunter, so he told them to deny it in public and to the boys in the back and that he would take the heat for the decision. If I remember the book correctly, the Undertaker was the only one in whom Shawn confided that wasn't initially involved in the plot to take the belt off of Brett in Montreal. But that was only after Taker confronted Shawn about his involvement after the fact. Shawn had to sit down with him and explain in detail the reasons behind it and why he felt it was the only way to do business at the time. Taker agreed and subsequently left it alone.
