The Supreme Court is headed into its final few weeks with nearly half of the cases heard this year still undecided, including ones that could reshape the law on everything from guns to abortion to social media. The justices are also still weighing whether former President Donald Trump is immune from criminal prosecution in the election interference case against him, more than a month after hearing arguments.

The court heard 61 cases this term, and 29 remain unresolved, with some decisions expected Thursday and Friday.

Here’s a look at some of the major undecided cases:

Presidential immunity

Donald Trump is arguing that former presidents are immune from prosecution for official acts they took in office and that the indictment he faces on charges of election interference must be dismissed.

The Supreme Court has previously ruled that former presidents can’t be sued in civil cases for what they did in office, but it has never weighed in on criminal immunity. The timing of the decision may be as important as the outcome. Trump’s trial in Washington, D.C., may not take place before the November election, even if the court rules he is not immune.

A former Pennsylvania police officer is challenging the validity of obstruction charges brought against hundreds of people who took part in the violent assault on the Capitol on Jan. 6, 2021. Trump faces the same charge of obstructing an official proceeding.

The issue is whether a law meant to discourage tampering with documents sought in investigations can be used against the Capitol rioters.

Abortion pill

Abortion opponents are trying to make it harder for pregnant women to obtain medication abortions. They want the Supreme Court to roll back changes made by the FDA that have made it easier to obtain mifepristone, one of the two drugs used in nearly two-thirds of abortions in the United States last year. Those include eliminating the need for in-person visits and allowing the drug to be mailed.

Most Republican-led states have severely restricted or banned abortion since the Supreme Court overturned Roe v. Wade in 2022. The high court’s decision in this case will affect abortion even in states where it remains legal.
Emergency abortion

There’s a second abortion case on the docket this year: whether doctors can provide that medical procedure in emergencies in states that banned abortion after the court overturned Roe v. Wade.

In a case out of Idaho, the Biden administration says abortions must be allowed in emergencies where a woman’s health is at serious risk.

The state argues that its strict abortion ban does allow abortions to save a woman’s life, and doesn’t need to expand exceptions for health risks.

Guns

The justices are weighing whether to uphold a federal law that seeks to protect domestic violence victims by keeping guns away from the people alleged to have abused them. An appeals court struck down a law that prohibits people under domestic violence restraining orders from possessing firearms. That court found that the law violated the 2nd Amendment right to “keep and bear arms” following the Supreme Court’s 2022 ruling that expanded gun rights and changed how courts are supposed to evaluate gun restrictions.

Homelessness

The most significant Supreme Court case in decades on homelessness centers on whether people can be banned from sleeping outdoors when shelter space is lacking.

A San Francisco-based appeals court decision said that amounts to cruel and unusual punishment.

Leaders from California and across the West say that the ruling makes it harder for them to regulate homeless encampments encroaching on sidewalks and other public places.

Advocates say it would criminalize homelessness just as rising costs have pushed the number of people without a permanent place to live to record levels.
Bump stocks

The Trump administration banned bump stocks, a gun accessory that allows rapid fire like a machine gun, after they were used in the deadliest mass shooting in modern U.S. history.

The ban is being challenged by a Texas gun shop owner who says the Justice Department was wrong to reverse course and declare them illegal machine guns after the 2017 Las Vegas massacre. The Biden administration argues banning them after the shooting that left 60 people dead was the right call.

Chevron

The justices could overturn a 40-year-old decision that has been cited thousands of times in federal court cases and used to uphold regulations on the environment, public health, workplace safety and consumer protections. The decision colloquially known as Chevron calls on judges to defer to federal regulators when the words of a statute are not crystal clear. The decision has long been targeted by conservative and business interests who say Chevron robs judges of their authority and gives too much power to regulators.

Air pollution

Republican-led, energy-producing states and the steel industry want the court to put the Environmental Protection Agency’s air pollution-fighting “good neighbor” plan on hold while legal challenges continue. The plan aims to protect downwind states that receive unwanted air pollution from other states.

SEC

Another important regulatory case could strip the SEC of a major tool in fighting securities fraud and have far-reaching effects on other regulatory agencies. The court is being asked to rule that people facing civil fraud complaints have the right to a jury trial in federal court.
