A panel set up to hear Australian swimmer Nick D'Arcy's appeal against his axing from the Beijing Games team has reserved its decision.

D'Arcy appeared at a Court of Arbitration for Sport (CAS) hearing in Sydney which went for more than five hours on Thursday where he appealed the Australian Olympic Committee's (AOC) decision to cut him from the team.

The Queenslander was thrown off the team last month for bringing the sport and the team into disrepute for his role in a bar altercation.

CAS panel member, John Winneke QC, said a decision would be handed down "soon, probably within a couple of days."

Australian Olympic Committee president John Coates said D'Arcy had received a fair hearing.

"Each side made their submission and there was an opportunity for Nick to be cross-examined, me to be cross-examined and then there was responses to the submission," Coates told reporters after the hearing.

"They adjourned and then came back and said that the matter's been reserved and we just wait now for them to prepare their judgment."

Asked if he was satisfied that everyone received a fair hearing, Coates said: "absolutely".

Coates said D'Arcy was not cross-examined on anything pertaining to his criminal charges.

"Nor should he be," Coates said.

D'Arcy refused to comment after the panel's decision.

"I can't comment, it's with the lawyers at the moment," D'Arcy told reporters.

His lawyer Jack Leitner said the the proceedings were confidential and was equally tight-lipped.

"We won't be making any comment until such time until the decision has been released," Leitner said.

D'Arcy, 20, still faces a charge of recklessly inflicting grievous bodily harm on Commonwealth champion swimmer Simon Cowley.

The charge stems from an alleged altercation between the pair at a Sydney bar just hours after D'Arcy was announced as part of Australia's swimming team for the Beijing Games from August 8-24.

Cowley suffered a broken jaw, broken nose, fractured eye socket, crushed cheekbone and fractured palate in the incident and is yet to publicly speak on the matter.

D'Arcy's court case has been adjourned until June 17.
