AS IT HAPPENED: 10 arrested at #HoërskoolOvervaal amid violence  

The Gauteng Education department attempted to have 55 pupils, to be taught in English, placed in an Afrikaans medium of instruction high school.

The North Gauteng High Court on Monday set aside the department's decision to admit these 55 learners to Hoërskool Overvaal in Vereeniging, saying that school has no capacity to receive the pupils, let alone to do so on such short notice and to effectively convert to a dual medium school. 

EFF members also protested against the need to have Afrikaans-medium schools in the country.
