Local school principals are concerned legal action against schools could become more common after a judge ruled that the suspension of a boy who refused to cut his hair was unlawful.
In a case that made headline news, the family of Lucan Battison, a 16-year-old student from St John's College in Hastings, took the school to court over the issue.
Lucan was suspended from St John's on May 22 after he refused to cut his locks. He had offered to tie his hair in a bun as the school rules required it to be "off the collar and out of the eyes" but the school took a hard line and suspended him.
Justice David Collins ruled that the decision to suspend Lucan was unlawful as it was too harsh a penalty, and the school's rule over hair length was vague and uncertain.
The principal of Wanganui City College, Peter Kaua, said his school had clear rules about hair, but they were mainly around colour.
