Mohamed Haneef's lawyers say the Australian Federal Police (AFP) repeatedly denied their client's request for a lawyer to be present during his first interview.
Dr Haneef was charged with supporting a terrorist organisation last year, but the charge was later dropped.
Lawyer Rod Hodgson says the AFP has been forced to disclose seven previously-withheld transcripts of interviews with Dr Haneef that will be used in the Clarke inquiry into the handling of the case.
Mr Hodgson says the transcripts show Dr Haneef was easily able to explain his actions to police and so should not have been charged.
"The other matter of great significance is that Haneef was asked three times in that first interview whether he wanted a lawyer present and on each occasion he said yes, but on each occassion the AFP didn't do anything about it," he said.
Push for overhaul of laws on terrorism In a paper in Judicial Review he said that the National Security Information Act "gives the appearance of having been drafted by persons who have little knowledge of the function and processes of a criminal trial". Court denies Lodhi leave to appeal Lodhi claimed the trial did not establish that he had actually decided to carry out a terrorist attack.
Haneef's lawyer says inquiry is weak The inquiry into Australian authorities' handling of the Mohamed Haneef case needs stronger powers to avoid becoming a "toothless tiger", the former terror suspect's lawyer says.
ASIO, police don't trust each other, report finds A LACK of trust between the Australian Federal Police and ASIO has hindered co-operation between the anti-terrorism agencies, a report commissioned after the collapsed prosecution of the Sydney doctor Izhar ul-Haque has found.
Secret policemen's bill: $7.5m Mr McClelland separately ruled out compensating or apologising to the Sydney medical student Izhar Ul-Haque, who a Supreme Court judge said had been kidnapped by ASIO officers. The conduct of ASIO in the case of Mr ul-Haque, who was cleared of terrorism charges, is being reviewed by the Inspector-General of Intelligence and Security, Ian Carnell.
