The family of a Black high school student in Texas on Saturday filed a federal civil rights lawsuit against the state’s governor and attorney general over his ongoing suspension by his school district for his hairstyle.

Darryl George, 17, a junior at Barbers Hill High School in Mont Belvieu, has been serving an in-school suspension since Aug. 31 at the Houston-area school. School officials say his dreadlocks fall below his eyebrows and ear lobes and violate the district’s dress code.

George’s mother, Darresha George, and the family’s attorney deny the teenager’s hairstyle violates the dress code, saying his hair is neatly tied in twisted dreadlocks on top of his head.
