The Big Cases Still to Be Decided at the Supreme Court

Decisions are expected throughout June.

The court — down to eight members since Justice Antonin Scalia's death in February — only has eight opinions left to release before it recesses, traditionally by the end of June.

Here are the three major cases we are watching:

Whole Woman's Health v. Hellerstedt (abortion)

Background:

This has the potential to be the most important abortion case in nearly 25 years. In 2013, Texas passed a law requiring that abortion providers have admitting privileges at a nearby hospital and that abortion facilities comply with the requirements for ambulatory surgical centers.

The plaintiffs in the case are clinics, including Whole Woman’s Health, and doctors providing abortion services.

Arguments:

Dr. John Hellerstedt, the commissioner of the Texas Department of State Health Services, the agency responsible for enforcing the challenged law, argues that Texas is trying to ensure patient safety and improve standards of care. He also argues that it’s the job of legislatures, not courts, to decide whether laws like these are medically necessary.

The plaintiffs argue that there's no evidence that the law promotes health and that it impedes women’s access to abortion. If the law goes into effect, they claim, the number of clinics providing abortions in Texas will drop to 10 or fewer. (The law is largely on hold while the Supreme Court considers the case.)

Possible outcomes:

There’s also the possibility of a procedural decision. The court could conclude that the plaintiffs did not present sufficient evidence about the capacity of the clinics that would remain in operation if the law went into full effect — so the court could send the case back to the trial court for the introduction of more evidence on that question.

Fisher v. University of Texas (affirmative action)

Background:

This case is the second trip to the Supreme Court for Abigail Fisher, a white woman who was denied admission to the University of Texas and filed a lawsuit challenging the university’s use of race in admissions.

In Fisher’s first case, the Supreme Court ruled that the lower courts were too deferential to school administrators and were required to look more closely at the evidence. The 5th Circuit Court stood by its earlier decision, and the case ended up back before the justices.

Texas has a unique admissions program, which first accepts approximately the top 10 percent of graduating seniors from each school in the state and then uses race as part of a holistic analysis (which also includes factors like community service, leadership and family circumstances) in filling the remaining spots.

Arguments:

Fisher’s attorneys argue that the implementation of the top 10 percent program is sufficient to increase minority enrollment, so there is no need to take race into account when filling the remaining spots.

Fisher attorney Bert Rein said during oral arguments that U.T. needed to prove that use of race in its admissions process was a “necessary last resort” in pursuing diversity, taking into account reasonably available nonracial alternatives.

On behalf of the university, Gregory Garre argued that U.T.’s holistic plan is necessary to complement its other admissions criterion and that it has a “meaningful impact on diversity.”

“Now is not the time and this is not the case to roll back student diversity in America,” he said.

Solicitor General Donald Verrilli, who recently stepped down from his position, also argued in support of U.T. on behalf of the United States.

Possible outcomes:

A majority of four could still decide the case, but some legal scholars believe there are legitimate concerns about making major constitutional decisions with less than a majority of the full court.

Given that, there’s a good chance the court will make a modest decision in this case.

The court could send the case back yet again, finding that there was not enough evidence because the lower court did not hold a full trial on the case.

The justices could also find that the Texas program is unconstitutional because of the existence of the top 10 percent plan, which is a race-neutral approach to diversifying the student body. (Residential segregation makes that inevitable.)

Or the court could affirm the lower court ruling and find that the Texas plan is perfectly constitutional.

United States v. Texas (immigration)

Background:

Texas and a number of other states challenged President Barack Obama’s executive action on immigration, which would offer deferred action — essentially temporary relief from deportation — to millions of undocumented immigrants. Obama’s plan would primarily affect the parents of U.S. citizens or lawful permanent residents, as well as individuals who arrived in the U.S. as children.

The lower court struck down the action as unlawful and issued a nationwide injunction, and the 5th Circuit affirmed the injunction. The Supreme Court accelerated its review of the case in order to hear it this term.

Arguments:

The case presents two major questions: first, whether Texas has standing to challenge the president’s action and, second, whether the president’s action was lawful.

Texas and the other states say the plan conflicts with existing immigration statutes by unilaterally granting status to individuals who are in the U.S. illegally.

They also argue that the plan is unconstitutional — that by crafting this plan, the president has failed to “take care that the laws be faithfully executed,” as the Constitution requires.

The administration argues that recipients of deferred action don’t receive lawful immigration status but are notified that they’re not a deportation priority. This would allow them to “come out of the shadows” and apply for work authorization, according to the White House.

At oral arguments, the court appeared divided 4-4 on whether the program was lawful and whether Texas may challenge it.

Possible outcomes:

A tie here would leave the lower court opinion in place, preventing the president’s executive action from going into effect, at least in the short term. If one of the conservative justices crosses over to join the liberal justices, the White House could begin rolling out the program, which has been on hold while the courts consider it.

The case is unlikely to be decided before the end of June, since it is very complex and was argued very late in the term.
