Details of a brawl between a girlfriend and her partner prompted a judge to wonder aloud why only the man was being charged by police.
Iran-Robert Manihera, 39, from Masterton, appeared in court earlier this week and was convicted of common assault, after a violent fight with his girlfriend, which began when she hit him over the head with a laptop.
"Is there any reason other than gender that she wasn't charged?" Judge Chris Tuohy asked the court.
Prosecuting sergeant Jodie Lawrence told the court how, on July 23, Manihera had been at the woman's house in Palmerston North.
Manihera was playing games on his laptop when the woman became angry with him because she wanted to go to sleep. When he refused to stop playing she grabbed his laptop and hit him over the head with it.
