The U.S. Supreme Court on Monday ruled it will not hear a petition by Los Angeles Rams owner Stan Kroenke and his team to settle a relocation lawsuit in arbitration.

The high court’s decision means the lawsuit will either be settled out of court or head to trial in St. Louis Circuit Court next year.

The case had faced long odds of reaching the Supreme Court, which hears only a fraction of thousands of petitions it receives each year. The NFL and its other teams are defendants in the lawsuit but were not involved in Kroenke’s petition to the court.

Last fall, after the Missouri Supreme Court ruled the relocation lawsuit should be decided in a St. Louis courtroom — and not in arbitration — Kroenke’s lawyers appealed in order to halt the court’s order until it could petition the U.S. Supreme Court.
