No justice for Panther: Brennan By MEGAN SAUNDERS July 11: The Chief Justice of Australia, Sir Gerard Brennan, said yesterday jailed former terrorist Lorenzo Ervin did not appear to have been accorded natural justice. Before adjourning a High Court hearing on whether Mr Ervin should be freed from prison where he has spent three nights, Justice Brennan told the Federal Government's lawyers natural justice was central to Mr Ervin's extradition case. "There is an obligation to accord natural justice which has not been observed," Sir Gerard said before adjourning the hearing until this morning. The High Court is expected to decide today whether Acting Immigration Minister Amanda Vanstone acted legally in revoking the visa of the former Black Panther and convicted hijacker. Sir Gerard said it was of "considerable importance" that Bob Gotterson QC, for the Federal Government, explain today how the rules of natural justice applied in the case which has created international reaction. Tensions reached boiling point outside the Commonwealth courts yesterday with protesters threatening to storm the building. Overseas, international protest groups extended their campaign to include South Africa, Greece, Italy and Sweden where groups will sign petitions and picket Australian embassies and consulates. They will join other human rights groups already campaigning in the UK, Ireland, New Zealand and the US against the Government's decision to jail Mr Ervin and revoke his tourist visa on the grounds that he was not of good character. The matter went straight to the High Court yesterday after Mr Ervin's legal team argued they had effectively been barred from lower tribunals. And the Government was forced to withdraw a claim that the case fell outside the jurisdiction of the High Court after Sir Gerard told Mr Gotterson that it was of "the greatest constitutional importance" that the court had authority to review unlawful government decisions. "It is a proposal which I regard as completely inconsistent with judicial review because it would isolate the executive from acts done which are unlawful and that would not be contributable to the constitution or the Parliament," Justice Brennan said. Mr Ervin's legal team argued that Senator Vanstone had acted unlawfully by cancelling Mr Ervin's tourist visa and denying him a temporary visa while the Federal Court reviewed the decision. Counsel for Mr Ervin, James Douglas QC, argued that Senator Vanstone had breached the rules of natural justice by failing to take into account his good conduct and character since being convicted and not giving him an opportunity to respond to ministerial concerns. Mr Gotterson was granted an overnight adjournment to compile the Government's defence on the issue after he said he had been given last-minute notice of the hearing. Mr Ervin released a statement from custody yesterday saying he was being treated "worse than I was in the American prison system" and vowing to let the world know. "I can easily see why so many Australian black prisoners have committed suicide, they have been driven to it by the Australian police State," he said.
