(Daily Mail) Several national fraternities and sororities are suing Harvard University over a 2016 rule that discourages students from joining single-gender social clubs by blocking them from leadership opportunities on campus.

On Monday, two fraternities and two sororities along with three anonymous Harvard students filed a lawsuit in Boston’s federal court, while another sorority separately sued the school in Massachusetts state court.

Both cases argue that the school’s policy discriminates against students based on their sex and spreads negative stereotypes about students who join all-male or all-female organizations.

Harvard officials did not immediately provide a comment about the lawsuits.
