Shane Warne appeared before an International Cricket Council (ICC) judiciary panel on Monday after being charged for dissent in the third Test between Australia and West Indies.
The Australian leg spinner was reported by umpires Aleem Dar and Billy Bowden after showing dissent over an appeal against them.
He appeared before ICC match referee Mike Proctor at the conclusion of play on Monday but an Australian team spokesman said a decision would not be made until Tuesday.
Monday's fourth day was soured by a series of controversial umpiring decisions that all went against the visiting team but Warne, speaking at a news conference before his hearing took place, denied his team had acted unfairly.
"I wouldn't say we over-appeal at all. If you don't ask you don't get."
West Indian coach Bennett King declined to comment on the issue."I'm really just here to comment on the West Indies and not what the opposition are doing," he said. "But I guess the thing that I was really proud of was that the West Indies played the game in the true spirit of cricket."
