After months of speculation that the Supreme Court would issue a landmark ruling either upholding or striking down affirmative action, the high court on Monday opted instead to avoid tackling the issue head-on, saving that question for another day.

In a 7-1 decision, the justices vacated a lower court's ruling that approved of the University of Texas' affirmative action program, and sent the case back down for further consideration. Writing the majority opinion, Justice Anthony M. Kennedy said the 5th U.S. Circuit Court of Appeals did not adequately address whether the university had properly applied that program in the first place.

Precedent from previous cases allowed schools to impose "narrowly tailored" affirmative action programs when "no workable race-neutral alternatives" are available, Kennedy wrote. But the appeals court merely took the school at its word that its program met those criteria, rather than thoroughly evaluating it.

"Strict scrutiny does not permit a court to accept a school's assertion that its admissions process uses race in a permissible way without closely examining how the process works in practice," Kennedy wrote.

However, the Supreme Court declined to answer that question itself, instead putting the onus on the lower court. In doing so, the justices avoided, for now, either upholding or abolishing wholesale the practice of affirmative action.

The case, Fisher v. University of Texas at Austin, stems from a lawsuit filed by a white woman, Abigail Fisher, who claimed the university denied her admissions application because of her race. Justice Ruth Bader Ginsburg was the lone dissenter in the case, while Justice Elena Kagan recused herself, presumably because she had worked on it as U.S. solicitor general.

While the ruling effectively allowed affirmative action to stand, the justices indicated that the program was "not on solid legal ground and could still be overturned," said Reuters' Lawrence Hurley. Subsequent cases could chip away at affirmative action, something the conservative justices seemed to already be preparing for.

Indeed, that gradual chipping could begin later this year. In March, the Supreme Court agreed to hear another affirmative action case in its next term. Some said at the time that the court, by taking on a second affirmative action case before deciding on Fisher, indicated it would wait until the second case to deliver a major ruling.

As SCOTUSblog's Lyle Denniston wrote back in March, the Texas case "focuses directly only on the specifics of an affirmative action plan at Texas's flagship university in Austin," whereas the Michigan case was "significantly broader" and thus more liable to produce a sweeping decision. That case, Schuette v. Michigan Coalition to Defend Affirmative Action, stems from a 2006 ballot initiative that banned race-based considerations in higher education and public employment.
