Seeking advice and help: fighting a rigged piano competition.

My son's 1st prize win in the Gainesville district concerto competition (the very city where the University of Florida is located)—which was his ticket to represent our district at the state finals—was suddenly replaced by a UF Assistant Professor's student just three hours after the official announcement email was sent.

We dug into it and found a massive, documented conflict of interest:

• The VIP Connection: The student who was abruptly handed 1st place is the private student of a University of Florida (UF) Assistant Professor—who also happens to be the State Vice President of this exact music association.
• The Inside Judge: The judge whose vote flipped the result sits on the executive board right alongside the VP.
• The Unfair Gap: My son performed a highly demanding, Diploma-level Beethoven concerto. While a Senior Concerto division normally requires a Level 12 proficiency or above, official documents prove the VP's student (who played Schumann) only just passed her Level 10 proficiency test that exact same day.

I filed a formal grievance to the FSMTA. The state board flatly refused my proposed compromises, refused to show us the score sheets, and brushed off the reversal as an "unfortunate email mistake."

Has anyone dealt with this kind of institutional corruption? How do I expose this and protect my son's faith in hard work? Any advice is welcome.
