WASHINGTON—Two U.S. Supreme Court decisions released Monday split the justices along strange lines in cases about an exception to the double jeopardy clause in the U.S. Constitution and gerrymandering of legislative districts in Virginia.

The U.S. Supreme Court on Monday declined to hear the appeals of two Kansas men convicted under federal regulations of gun silencers. The men argued that the right to “keep and bear arms” from the Second Amendment to the U.S. Constitution includes silencers.

The U.S. Supreme Court on Tuesday declined to hear the case of a group of Pennsylvania high school students who sued their school district for allowing students who identify as transgender to use the restrooms and locker rooms of the opposite sex. Without informing students or parents, the Boyertown Area School District implemented the policy during the 2016-17 school year, leaving some students shocked to find classmates of the opposite sex in their changing rooms and restrooms.

The U.S. Supreme Court on Monday ruled that consumers can pursue an antitrust lawsuit against Apple for the 30 percent commission it charges software developers to sell apps through its App Store. iPhone users claim Apple is unfairly monopolizing the app market since users must purchase software exclusively through the company’s online store. Justice Brett Kavanaugh joined the four liberal justices on the court in rejecting Apple’s request to end the lawsuit. Apple’s commission on every app sale was enough to persuade the hight court that the legal fight could proceed, he wrote.

The Supreme Court on Tuesday heard oral arguments in a case about a proposed citizenship question on the 2020 U.S. census. After the Census Bureau announced plans to ask all U.S. residents about the status of their citizenship in the once-a-decade national population survey, 18 states and the District of Columbia challenged the move, claiming that fewer immigrants would complete the survey for fear of revealing their illegal status to authorities.

The U.S. Supreme Court on Thursday declined to stop the Trump administration from enforcing its ban on bump stock devices, which allow semi-automatic weapons to fire in rapid succession, similar to machine guns. The ban took effect Tuesday.

The U.S. Supreme Court heard oral arguments Wednesday in the case of a threatened World War I memorial in Bladensburg, Md. First Liberty President Kelly Shackelford, who argued the case before the high court, said the lawsuit is a chance to clear up the confusing legal precedent about public displays with religious imagery, which he said everyone seemed to recognize “is in hopeless disarray.”

“We were very encouraged by the way things went today and are really hopeful,” he said at a news conference directly after the arguments.
