Amnesty International Australia is extremely concerned that the Federal Government's action to revoke the visa of Dr Mohamed Haneef, only hours after he was granted bail by a Brisbane magistrate, impacts on his right to a fair trial.

Dr Haneef has not been convicted of any crime. Minister Kevin Andrews has used his powers under the Migration Act regarding character assessment to revoke Dr Haneef's visa.

"This is a discretionary ministerial decision, which may have a significant impact on Dr Haneef's ability to seek a fair trial," said Amnesty International Australia's Nicole Bieske. "It is an unprecedented use of powers under the Migration Act, in the context of a terrorism trial."

Amnesty International Australia is further concerned at media reports that Dr Haneef is to be transferred to Villawood Detention Centre to await legal proceedings.

"We question plans to detain Dr Haneef in immigration detention in Sydney when his legal counsel is located in Brisbane," said Ms Bieske. "This certainly will not make it easy for him to prepare for the committal hearing on 31 August. This undermines Dr Haneef's right to adequate legal representation, already compromised by the provisions of Australia's anti-terror laws."
