The Youth Court heard that the 15-year-old, who cannot be named due to her age, had been told that the other girl had been making nasty comments about her.
She admitted: “I wanted to batter her.”
She saw the girl by chance in St. Helier town centre and confronted her and punched her. There was reddening to the victim’s face but no other injury.
Legal Adviser Samantha Morris, prosecuting, said the teenager was already subject to a binding over at the time, imposed on 21 March for a series of previous offences, including shoplifting, malicious damage, being drunk and disorderly, assaulting police officers and using abusive language.
Advocate Lucy Marks, defending: She does realise that acting like this will get her in trouble and before the courts.”
She also said that drinking had been partly to blame, but added: “The alcohol abuse has stopped.”
Magistrate Bridget Shaw noted that the teenager was communicating better with support services and said: “There are some good things.
“But you have to remember that you can’t go around punching people. Not only is it bad for your victim, but it’s bad for you as well.”
The Magistrate imposed a restraining order, forbidding the teenager from having any contact with the victim.
