Today, the U.S. Supreme Court issued stays on two nationwide injunctions involving the Trump administration's ban on military service by transgender people. Previously, federal district courts in California and Washington state had issued the injunctions to put the policy on hold while litigation continued. The Supreme Court's stays on those injunctions means that the administration may now implement the policy while litigants fight over its legality and constitutionality.
When two firefighters brought an age discrimination suit against their tiny fire district, the fire district defended itself by saying that the Age Discrimination in Employment Act (ADEA) didn't apply. According to its reading of the law, only employers with at least 20 employees were covered, and it didn't meet that threshold. The firefighters argued that the 20-employee threshold only applies to private-sector employers. This jurisdictional question was appealed all the way to the Supreme Court.
