The Court of Appeal on Tuesday rejected an application that would have given Attorney-General Jarrod Bleijie more time to try to have Alan Leahy stand trial for the 1991 murders of his wife Julie-Anne Leahy and her friend Vicki Arnold. Former state coroner Michael Barnes last year ordered that Mr Leahy be committed to stand trial after concluding during a third inquest into the deaths that they were deliberate and not the result of a murder-suicide.

But the Supreme Court later overruled that decision and Mr Bleijie's attempt to have it reversed failed.

Mr Leahy said he was grateful that judges on multiple occasions had identified ``comprehensive errors'' made by Mr Barnes.

``My only regret is that the decision did not require the Court of Appeal to make findings about other alleged errors by Coroner Barnes,'' he said yesterday.

``Until I have received legal advice about my options in respect of others involved in this flawed process, I will not be commenting further.''

Mr Bleijie had applied for an extension to lodge an appeal against the Supreme Court's decision that overturned the coroner's ruling for Mr Leahy to stand trial, given that he did not file for appeal within the 28-day time frame.

However, the Court of Appeal rejected the application on the basis that Mr Bleijie would have little chance of success if an appeal were granted.

The court also ordered the state government to pay 70 per cent of Mr Leahy's legal costs.
