A civil rights group is taking legal action against legacy admissions at Harvard University. It says the practice discriminates against students of color by giving special consideration to mostly white children of alumni. The practice has faced growing criticism after the recent Supreme Court decision that ended the consideration of race in college admissions at Harvard and the University of North Carolina. The decision ended admissions policies used by American colleges to increase the number of Black, Hispanic and other minority groups. The legal action was filed Monday by Lawyers for Civil Rights, a nonprofit group based in Boston. The group filed the complaint on behalf of Black and Latino community groups in New England. It argued that Harvard’s admissions system violates the Civil Rights Act.
