Attorney General Jeff Sessions Jefferson (Jeff) Beauregard SessionsGOP set to release controversial Biden report Trump's policies on refugees are as simple as ABCs Ocasio-Cortez, Velázquez call for convention to decide Puerto Rico status MORE on Tuesday rescinded a series of Obama-era guidelines aimed at promoting diversity in higher education.

The documents laid out legal guidelines for how colleges could properly consider race in admissions decisions in order to promote campus diversity. Rescinding the guidelines does not change official U.S. policy, but marks a return to the George W. Bush-era approach of “race-neutral” college admissions.

The guidelines were among 24 that Sessions pulled back on Tuesday, deeming them “unnecessary, outdated, inconsistent with existing law, or otherwise improper.”

The Trump administration has argued that the rules violate Supreme Court precedent on affirmative action.

"The Supreme Court has determined what affirmative-action policies are constitutional, and the Court's written decisions are the best guide for navigating this complex issue," said Education Secretary Betsy DeVos Elizabeth (Betsy) Dee DeVosSpecial counsel investigating DeVos for potential Hatch Act violation: report NEA president says Azar and DeVos should resign over school reopening guidance The Hill's 12:30 Report - Presented by Facebook - You might want to download TikTok now MORE in a statement.

The move has been harshly criticized by civil rights groups, who say that rescinding the guidances will be detrimental to students of color in the U.S.

The American Council on Education has already vowed to ignore the decision, saying that the administration is sending “precisely the wrong message” to institutions of higher education.

But Sessions argued that the decision to rescind the policies was intended to undo what he described as government overreach and previous administrations' efforts to "impose new rules on the American people without any public notice or comment period, simply by sending a letter or posting a guidance document on a website."

"That’s wrong, and it’s not good government," he said.

Still, abandoning the Justice Department guidelines does not change current U.S. law, and schools are allowed to operate as they choose, so long as their actions fit within existing legal precedents.

The move came days after Justice Anthony Kennedy announced that he would retire from the Supreme Court this summer. His departure means that the court will lose a key swing vote on affirmative action issues, while allowing President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

Affirmative action in college admissions is the subject of one high-profile lawsuit alleging that Harvard University has discriminated against Asian-American applicants in order to free up spots for other racial minorities.

The Justice Department weighed in on the side of the Asian-American applicants in April, asking a federal judge to order the release of years of Harvard admission records.
