WASHINGTON: The Supreme Court passed up new opportunities Monday to take on two hot topics — partisan gerrymandering and balancing LGBT and religious rights — and also left rulings about the Trump travel ban and other big cases for coming days as it began the final week of its term.

With the conservative justices in the majority in two 5-4 decisions, the court resolved two outstanding cases — ruling in favor of Texas electoral districts that a lower court had struck down as racially discriminatory and American Express in an antitrust dispute with states over the company’s rules prohibiting merchants from steering consumers to other credit cards that charge lower fees.

The court also refused to hear an appeal from a teenager who was convicted of rape and murder, and whose story was documented in the Net­flix series Making a Murderer.

Supreme Court punts

Two cases presented the court with the opportunity to decide issues left open by recent rulings.

One was a North Carolina lawsuit over congressional districts drawn for partisan gain. The other dealt with religious exemptions from anti-discrimination laws for opponents of same-sex marriage. That case was about a florist in Washington state who was found to have violated the state’s anti-discrimination law when she refused to provide flowers for a same-sex wedding.

The justices took the path of least resistance and asked courts in North Carolina and Washington to review the cases in light of Supreme Court rulings in a Wisconsin districting case and a Colorado appeal from a baker who wouldn’t make a wedding cake for a gay couple. It’s not clear that either case will turn out differently and both could return to the Supreme Court quickly, perhaps in time for the term that begins in October.

Texas redistricting

A different kind of gerrymandering, using race, was at issue in the ruling upholding all but one state House district in Texas. The case was unusual because the districts at issue were adopted by a court on an interim basis as part of a discrimination lawsuit, then approved by the state Legislature in what it said was an effort to end the litigation. That same court then determined that the districts were tainted by intentional discrimination or relied too heavily on race.

Justice Samuel Alito wrote for the court’s conservatives that the lower court made a mistake by not giving enough weight to the Legislature’s stated intent to end the lawsuit and instead demanding that the state prove it was not discriminating against minority voters. Justice Sonia Sotomayor wrote in her dissent that challenged districts “burden the rights of minority voters.”

Merchant fees

American Express won its case against states and the federal government over its rules that prevent merchants who accept its cards from encouraging consumers to use other credit cards that charge lower fees. The governments, and the court’s liberals, said American Express was restricting competition in violation of federal antitrust law. But Justice Clarence Thomas wrote for the five conservative justices that far from discouraging competition, American Express’ business model “has spurred robust interbrand competition and has increased the quality and quantity of credit-card transactions.”

‘Making a Murderer’

There was no comment from the court in rejecting an appeal from Brendan Dassey, who was 16 years old when he confessed to Wisconsin authorities that he had joined his uncle in raping and murdering photographer Teresa Halbach before burning her body in a bonfire.

Dassey’s attorneys had argued that he is borderline intellectually disabled and was manipulated by experienced police officers into accepting their story of how Halbach’s murder happened. They wanted his confession thrown out and a new trial ordered.
