The alleged victim was shot in January after allegedly being forced into a car against his will by Marcus John Williams and Jacob Adam Williams. The prosecution is arguing that the alleged shooting was in retaliation for a supposed earlier incident.

Despite sharing the same last name, Marcus and Jacob are not related. They, along with Tayla Ebony Stevenson, have been charged with causing grievous bodily harm.

In the Launceston Supreme Court on Friday, Crown prosecutor John Ransom told Chief Justice Alan Blow that doctor's advice had suggested the alleged victim would be unable to give evidence in a preliminary proceedings hearing due to "physical disability".

Mr Ransom contended that the alleged victim met Jacob and Marcus at the McDonald's on Wellington Street in South Launceston.

"Marcus and Jacob Williams took [the alleged victim] in a car out to Kings Meadows," Mr Ransom said. "A handgun was produced."

"The net result was he was shot in the leg."

But defence counsel Evan Hughes argued that the man allegedly shot in the leg would be a "very significant witness" and would be fit to give evidence.

"A doctor described him as being able to get around on elbow crutches," Mr Hughes said.

"We will be asserting that [the alleged victim] is ... fabricating the allegations."

Chief Justice Blow granted the application, meaning the alleged victim will give evidence via audiovisual means.

"So far as physical disability is concerned, I think defence counsel has made a valid point," Chief Justice Blow told the court.

Marcus, Jacob and Ms Stevenson will appear in the Launceston Magistrates Court on May 17, where the alleged victim will give evidence.

The case is expected to go to trial.
