The Young Communist League (YCL) has condemned a school in Mpumalanga for taking the Education Department to court in a battle to retain its status as an Afrikaans-medium school.
In February a full bench of the high court set aside an earlier ruling and ordered the school to admit 113 English-speaking pupils.
The school alleges the department did not follow correct procedures when it declared the school dual medium.
The court this week reserved its judgment in the matter.
Castro Ngobese, YCL spokesman, said the action sought to protect the "laager mentality" and rekindle the Soweto uprisings that took place 31 years ago when Afrikaans was imposed on African schools.
"We view these actions as undermining the political advances we have made in the transformation of the education system in our country over the past 13 years of our democratic dispensation," said Ngobese.
Ngobese said it was the league's contention that Afrikaans would not survive as a language if it sought to fight for its sole and exclusive survival in public schools.
"There is a need for the promotion of all South African languages, especially the indigenous languages in our schools," he said.
The school has, for a number of years, had black pupils who chose to be educated in Afrikaans.
But earlier this year, 113 pupils at the school wanted to be taught in English.
The education department pressured the school to change its language policy.
