The Supreme Court on Wednesday dismissed a bunch of petitions challenging the Central Bureau of Secondary Education’s decision to conduct re-examination of Class 12 economics paper after the alleged paper leak.

The apex court has said that the decision on re-examination is up to the CBSE, and court can’t decide writ petition on the matter.

The board had announced a re-examination of the Class 12 economics paper on April 25. Initially, a re-examination for class mathematics 10 was also announced, but the board on Tuesday ruled out re-test for Class 10.
