The man suffered moderate injuries — bruising and abrasions — for which he received medical attention at Gisborne Hospital. He claimed Wilson had used a metal object in the attack.
Wilson subsequently pleaded guilty to assault with a blunt instrument. Judge Warren Cathcart sentenced him to four months community detention after converting a nominal end sentence of seven-and-a-half months imprisonment.
Community detention was the appropriate outcome the judge said. Imprisonment would not reflect Wilson's health difficulties or assist with his rehabilitative needs. Home detention would require Wilson to be at home 24 hours a day, seven days a week, and could put his elderly parents with whom he lives, at risk.
An alternative sentence of supervision was ruled out as unsuitable by the probation service.
The judge set a sentence starting point of 12 months imprisonment, uplifting it by one month for previous relevant convictions (none of which related to this victim).
There was discount of three months for Wilson's health issue. While not causative of the offending, it certainly contributed to the background context, the judge said.
There was a full 25 percent discount for early guilty plea.
The court was told Wilson's condition was first diagnosed when he was 20. He remained in the care of his parents and received an invalid's benefit. He had been hospitalised many times for his illness, which was exacerbated by his use of alcohol, cannabis, and methamphetamine.
He was now back on psychiatric medication but had not been on it at the time of this incident.
His friendship with the victim had ended.
