Eliminating the terms “race and ethnicity” from the American Bar Association’s law school accreditation rules will hobble longstanding efforts to bring in diverse students and faculty, critics warned in public comments on the proposal.

A conservative activist who led the campaign against affirmative action in college admissions is suing two major law firms for fellowships that they offer to increase diversity in the legal profession.

Affirmative action has long been controversial. Proponents say it’s a way to address historical discrimination. On Thursday, the U.S. Supreme Court ruled in two cases to strike down race as a factor in admissions processes.The decision's impact will be tough to measure in nine states, including Arizona, that already bar public universities from considering race in admissions.Since 2010, Arizona hasn’t allowed public universities to consider race. But private universities were still able to, to an extent.

Colleges across the country will be forced to stop considering race in admissions under Thursday’s Supreme Court ruling, ending affirmative action policies that date back decades.

The Supreme Court killed affirmative action, but not for military academies or the legacy admissions that protect the ruling class.
