The husband of a Queensland magistrate threatened to have the family of a grandmother he's accused of assaulting evicted from their home, a court has heard.
David Pirie made the claim as he was arguing with neighbours, including alleged victim Jennifer Toohey, according to another neighbour who gave evidence in Brisbane District Court.
Michael Field on Tuesday recounted the day of the neighbourhood dispute in February 2017, when Pirie allegedly hit Ms Toohey with a shovel handle and also punched her.
Mr Field told the jury his attention was drawn by an "almighty" argument ringing out across their usually-quiet Gold Coast hinterland street.
In a heated exchange that lasted about five minutes, he heard Pirie yelling "you're a f****** fat bastard, you're a fat bastard" about six times, he told the jury.
"The only other thing I could hear that was coherent was he said "I could have you lot out of your house in two weeks'," Mr Field said.
The argument became so intense that Mr Field called triple-0.
The prosecution argues Pirie and son Lachlan attacked Ms Toohey after going onto her property.
The Piries and the Tooheys had been in a long-running dispute, and on the day of the alleged assault, they squared off over loud music.
After the pair insulted each other, Pirie twice hit Ms Toohey with the handle and punched her in the face, crown prosecutor Chris Cook said.
Pirie's lawyer Tony Kimmins doesn't dispute that his client hit Ms Toohey, but claims it was self-defence rather than assault.
Mr Kimmins told the jury Ms Toohey had driven onto the Piries' property and became aggressive, and came at him with clenched fists.
The trial continues.
