<h1>Supreme Court to Review Calcutta High Court's Annulment of OBC Status for 77 Muslim Classes in West Bengal.</h1> The Supreme Court is set to hear pleas on January 28-29 challenging a Calcutta High Court decision that annulled the OBC status of several castes in West Bengal, granted since 2010. The High Court ruled the reservations illegal, stating they were based on religion, affecting 77 classes of Muslims. It maintained that those who had already benefited from the reservations would not be impacted. The Supreme Court previously requested the West Bengal government to present data on the social and economic status of the newly included castes in the OBC list and their representation in public sector jobs.
