NOTE: The General Conference response does not call it illegal.
Yes, it says it "sets aside." It says it is a threat to unity. But, it does not call it illegal.
I expect that Bob will ask me if I think it is illegal. So, I might as well make a statement of what I think.
1) I think that there are valid points to be made on each side. Some for saying that it is illegal. Some for saying that it is legal.
2) Personally I argue that it is legal.
3) Neither Bob nor I, nor the typical person reading these posts is in a position with the authority to decide whether or not it is legal. In the U.S. questions of legality are decided by those trained in law. The Roman Catholic Church has a whole system set in place to decide the legality of church related issues. The SDA Chruch typically has those decisions made by lawyers and/or administrators.
4) My belief is that the decision as to the legality is probably going to be made by those who will say that the action of the PUC was illegal.
IOW, while I believe that there are valid points on both sides, the chances are greater than 50% that the decision will be that it was illegal.
How can I say this since I will personally argue that it is legal? Very easy. One who argues before a judge must know and understand the opposing arguement, be prepared to meet that opposing arguement, know and understand the judge(s) and how they are likely to rule on issues and have a realisitic understanding of the probability of obtaining a favorable ruling on each issue raised. My perception is that there is a greater probability of it being declared illegal than there is of it being declared legal.
