I don’t think it’s discriminatory to say that hair of a certain length must be neatly tied back.
But her hair at the relevant time wasn't that long. The school's issue seems to have been that it was frizzy and therefore sticking out. I'm sure they wouldn't require a Caucasion child with medium length hair to tie it back.
I feel sorry for the school, £8,500 for any school/LA to cough up is a lot and could have been spent on other more well-meaning stuff like textbooks....
Oh, dear. If only there was an easy way they could have avoided that expense. Like not being racist.
The school had rules and they apply to everyone
Rules that contravene the Equality Act 2010 don't apply to anyone. Maybe the school should have thought about sticking to the rules imposed by that Act?
