arena but rather by external governance matters that are the responsibility of the AFL: the quality of match facilities and the performance of timekeeping duties. This line of argument leads to the view that natural justice required the game to be awarded to Fremantle. Investigation and ruling The AFL football operations department commenced an investigation of the conclusion of this match, to be conducted by AFL Investigations Officers Allan Roberts and Bill Kneebone. After interviewing the umpires, timekeepers, AFL match manager and a spectator, as well as reviewing the television replay, they concluded that "It would appear that the timekeeper(s) have not complied with (Law 10.4.1 End of Quarter)." During a four-hour hearing on Wednesday, 3 May, the AFL Commission heard submissions from representatives of both teams and the AFL investigating officer. The result of the hearing was that Fremantle was awarded victory and four competition points, with the official final score reading St Kilda: 13.15 (93) vs. Fremantle: 14.10 (94). On 4 May, St Kilda ruled out a legal challenge to the outcome, ending any further uncertainty. The commission stressed that this decision was in response to a unique set of circumstances external to the game rather than overruling an on-field umpiring decision; hence, no precedent was set for the overturning of results decided by controversial umpiring decisions, errors by goal umpires, etc. The key factor was that the timekeeper had not fulfilled his duties by failing to sound the siren continuously until the umpires acknowledged the end of the game. This prevented the umpires from being able to end the game at the correct time. An upgrade of the York Park siren was implemented by the grounds manager, former Western Bulldogs player Robert Groenewegen, in May 2006, in anticipation of the Round 12 game at the venue. Chris Connolly on the arena A secondary point for discussion was Chris Connolly's angry march onto the ground. According to the rules of the game, the coach is not allowed onto the playing arena during the game. Because Connolly had walked onto the ground before the umpires had officially ended the game (after Steven Baker's secondary kick), he had contravened the rule, which would usually result in a fine and a "please explain" from the AFL but no other penalty. Commentators had pointed out that a fine was not mandatory but applied to a case on its merits and that, in
