Former Tennis Australia director Harold Mitchell has been fined $90,000 for corporate breaches in the lead-up to the 2013 Australian Open.
It comes after the Federal Court found he overstepped the line in negotiating television rights for that year's grand slam tournament.
Mr Mitchell breached his duties as a director on three occasions, including by passing information to Seven West director Bruce McWilliam in 2012.
Seven West won the contract for the Open.
The Australian Securities and Investments Commission took Mr Mitchell and former Tennis Australia president Steve Healy to court over the saga.
The court in July threw out the entire case against the latter and the bulk of the allegations against Mr Mitchell.
But Justice Jonathan Beach did find the former director "stepped over the line in his dealings with Mr McWilliam".
"There were some things that he communicated to Mr McWilliam that he ought not to have done, particularly in the latter part of 2012".
But the judge also said none of this caused any damage to Tennis Australia.
In a separate ruling on Wednesday, he penalised Mr Mitchell $90,000 for breaching his duties as a director.
