A decision to declare Benvenuto Cellini a non-runner in the Derby has been criticized, with some calling it an "extraordinary act of self-sabotage" and others labeling it "absurd and nonsensical". The British Horseracing Authority views the situation as a test of the rules, but does not consider it a precedent. The move led to a significant Rule 4 deduction on winning bets, sparking debate among racing fans and bookmakers.
