An Adelaide man, who threw a bucket of acid over his victim, committed the cowardly and unprovoked attack at the request of his former partner, a court has been told.
Anthony James Lloyd's attack on Geoffrey McLean came in May 2022, just a few months before Mr McLean's alleged murder in an unrelated incident.
Armed with a bucket of alcohol and hydrochloric acid, Lloyd threw the liquid towards the 55-year-old, hitting his face, shoulder, arm and back.
"Mr McLean immediately felt a cold burning sensation and pain," District Court Judge Joanne Tracey said in sentencing on Wednesday.
"His breathing was affected and the taste of the chemical was burning his throat."
Judge Tracey said Lloyd also tried to set his victim on fire and in the wrestling that followed Mr McLean had three teeth pulled loose.
He sustained serious burns, including some on his back which were full thickness.
The judge said that while Lloyd had split from his former partner, who was then in a relationship with the victim, the 63-year-old was still besotted with her.
"You are said to have lent her money, purchased a car for her and provided her with accommodation," Judge Tracey said.
In the three months before the attack, the woman had made serious allegations about Mr McLean's behaviour towards her and had asked Lloyd to get him out of the house by hurting him.
After the woman rejected his suggestion she go to the police, Lloyd said she finally wore him down.
The judge said she accepted Lloyd was genuinely remorseful and could not understand his offending, believing he was motivated by whatever the woman wanted from him.
"This was a serious, unprovoked attack on Mr McLean," she said.
"Your offending was voluntary, premeditated and cowardly."
Taking into account his guilty plea to aggravated causing serious harm, Judge Tracey jailed him for five years and six months with a non-parole period of three years.
