The Tasmanian Law Society wants the State Government to appoint two Supreme Court judges when it goes through the process of filling a vacancy.

With the retirement of Justice David Porter in May, pressure will be on the remaining judges to hear pending appeals and new trials.

The hunt for a replacement for Justice Porter has started, but Law Society president Matthew Verney said the Government should be looking to appoint two judges not just one, to bring the total to seven.

"The work load now is more than six judges can handle ... [and] it's now going to start to impact victims, on the justice system, obviously on offenders," he said.

The Law Society said even with moves by the State Government to make appointing temporary judges easier, significant delays in getting cases to trial were expected.

On Monday, the news that the trial of a 73-year-old man accused of gunning down his estranged wife in a busy Hobart street would still be two months away raised concerns about delays in the Tasmanian justice system.

Almost a year since Klaus Dieter Neubert allegedly murdered his 37-year old wife Olga Neubert, he still will not stand trial before July.

The accused also allegedly shot her friend Josephine Ramos Cooper in the hand.

Mrs Ramos Cooper was in court on Monday to hear if it would be July or perhaps even August before Neubert stood trial.

"What I hear today is traumatising [me]," she said outside the court.

"It takes a long [time], and goes on and on, all this court hearings, it's not good for my health."

The court heard the Crown was waiting for further information relating to Neubert's mental health.

"My health, I've been so traumatised by this I can't go to sleep every night," Mrs Ramos Cooper said.

But the wait on further information to the court is not the only reason for the delay.

Stephen Roy Standage was sentenced in 2014 to 48 years jail for the murders of Ronald Jarvis in 1992 and John Thorn in 2006.

He is now appealing against the 2012 ruling by Justice Peter Evans that the murders could be heard at the same time, despite the 14 years between them.

If he is successful Standage would be re-tried, but this time with a separate trial for each murder.

The original trial lasted five months.

The appeal itself is expected to take three judges at least two weeks to hear.
