Hawthorn has suffered a double dose from the AFL with Campbell Brown hit with a $7500 fine by the AFL after admitting that he had lied in a tribunal hearing involving West Coast Eagles star Chris Judd, while the club was fined $25,000 for filming an AFL match without permission.

The AFL ordered an investigation into Brown's actions at the tribunal hearing after the Hawthorn defender admitted to a television program earlier this week that he had lied to protect Judd.

Judd was reported during the round nine match against the Hawks for misconduct in that he made inappropriate contact to the face of Brown during that match. The Brownlow Medallist was cleared after Brown failed to support any claim that he may have been eye gouged.

Brown's revelations on television earlier this week prompted the AFL investigators Allan Roberts and Bill Kneebone to interview the player and speak to Hawthorn

AFL Football Operations Manager Adrian Anderson said that the integrity of the tribunal system was important for the competition and that Brown had crossed a line by his actions.

After discussion with the club, the AFL decided not to refer the matter back to the tribunal and Brown was given a $15,000 fine, half of which was suspended. The investigation cleared the Eagles of any wrongdoing in the matter.

The AFL also fined the club after they filmed the round 18 match between Western Bulldogs and St Kilda at Telstra Dome.

"The AFL received a formal response from the Hawthorn Football Club earlier this week in which the club made a full apology for its actions and acknowledged its wrong-doing," Anderson said.

"The club handed over all videotape from the night and has fully co-operated at all times with the AFL's Investigation into this matter."

"The AFL wishes to place all clubs on notice that ordinarily, the sanction for a breach of the Regulations of this nature would be much higher and that all Clubs are on notice that any subsequent breaches will be dealt with accordingly," he said.

The fine is $50,000 with half of it suspended.

Hawthorn chief executive Ian Robson said the club was unhappy with the severity of Brown's punishment and the second hefty fine, but pleased to move on from the incidents.

"While the club is disappointed that a financial penalty has been levied upon Campbell, it is pleased that the matter was dealt with quickly, leaving player and club to focus on this week's match against Port Adelaide on Sunday at Aurora," Robson said on Wednesday night.

In regard to the sanction imposed by the AFL for unlawfully videotaping the match between the Western Bulldogs and St Kilda at Telstra Dome, Robson said: "The club has fully co-operated with the AFL in their inquiry. Not withstanding the clubs' admission of guilt, in both instances we believed that a severe reprimand and suspended sentence would have been adequate.”
