The AFL Tribunal upheld a three-match suspension for Melbourne Demons forward Jacob van Rooyen after he struck Aliir Aliir [1].
The decision removes a key offensive player from the Demons' lineup during a critical stretch of the season. It also establishes a precedent regarding the types of expert testimony the league's disciplinary body will accept during hearings.
The tribunal rejected a bid by the Melbourne football club to introduce evidence from a biomechanist to defend the player [1]. The team sought to use the expert's analysis to challenge the finding that van Rooyen had struck the opposing player [2].
Despite the attempt to introduce scientific testimony, the tribunal ruled that the biomechanist's evidence could not be admitted as a defense [1]. The governing body said the original finding of striking was accurate and the penalty was appropriate [2].
Van Rooyen now faces a ban of three matches [1]. The ruling follows a disciplinary hearing where the tribunal reviewed the incident involving Aliir [1].
This case highlights the tension between clubs attempting to use advanced data and the tribunal's reliance on traditional officiating and video review. While clubs increasingly employ specialists to analyze player movement, the AFL Tribunal remains the final arbiter on whether such evidence is admissible in disciplinary matters [2].

The rejection of biomechanical evidence suggests the AFL Tribunal is hesitant to allow specialized scientific testimony to override official match reports or video evidence. For clubs, this indicates that relying on technical data may not be a viable strategy for overturning suspensions in the current disciplinary framework.
