Charles Zentai, a Perth man wanted for questioning over a Holocaust-related war crime, has asked the Federal Court to formally declare him a free man.

Mr Zentai has spent the past six years fighting a request from the Hungarian government for him to face questioning over the death of a Jewish teenager in 1944.

The Federal Government approved his extradition but the Federal Court recently overturned that decision.

The 89-year-old has been on bail since December and today the Federal Court was told he would remain on bail unless the court clarified his status and quashed his extradition order.

His son Ernie Steiner says his father wants just wants to move on.

"It'll be great to have those statements and declarations but there's been no indication from Hungary, no indication from the Commonwealth about whether they'll appeal," he said.

The Federal Government can still appeal against the Federal Court decision.

Mr Zentai has spent more than $200,000 fighting the case and was imprisoned for two months before his appeal was heard.

Mr Steiner says his father will not be seeking compensation.

"Even though he has been wrongfully imprisoned and wrongfully arrested, my father just wants to get on with his life and live his last few years in peace," he said.

Justice Neil McKerracher has reserved his decision.
