I want to trust the judge's judgement, and would rather just ask them their reasoning but I haven't been able to find them.A protest fee. If your protest is upheld, you get your money back. If not the club sponsoring the show keeps it. The standard lists the procedure for protests. It is not done often, but it can be done. Must be in writing, and must be before the show is complete. Read the standard for specifics.
I am not advocating protesting when the judging does not go your way. But it IS appropriate if the judge really screws up badly. I know someone who protested his own bird's win...he felt that there was a much better bird that should have won.
