Seven American students are suing a Texas school district over its dress code policy banning boys from having long hair.
The lawsuit claims that school officials suspended a nine-year-old boy for a month, barred him from recess and normal lunch breaks as punishment for long hair.
He and the other students, aged seven to 17, say the policy violates the constitution and a federal law prohibiting gender discrimination.
The school district said it is reviewing the lawsuit.
Magnolia Independent School District, which serves roughly 13,000 students about 40 miles north-west of Houston, did not return a request for comment.
According to its dress code policy, boys cannot wear their hair over their eyes, past the bottom of their ears, or past the bottom of a dress shirt collar.
Facing backlash this summer, Magnolia defended the policy, saying it reflects the values of the community at large.
