I strongly disagree with this. The decision should be made by the judge (or judges) who is officially selected for the tournament. Some "authorities" should not interfere in someone else's business. If they can't agree, they should postpone it.
Well, if these are truly recognized authorities, for example, from the Tournament Committee, and the judges of the tournament don't object, then why not?
The final decision should, of course, be made by the tournament judge, but why can't his decision be based on the conclusions of the person or people he trusts? A list of whom can also be agreed upon before the start of the tournament; in my opinion, this will make life easier for both the judges and the players.
