A lawyer for the plaintiffs declined to comment Thursday. A Rams spokesman could not be reached.

The other lawsuits involved fans who bought tickets and team merchandise and tried to get some of their money back, season ticket holders who sued over the price of personal seat licenses, and the dome authority, officially called the St. Louis Regional Convention and Sports Complex Authority, which went to court over the Rams’ former practice facility in Earth City.

Kroenke’s appeal for arbitration faces long odds of ever reaching the nation’s highest court, which hears only a sliver of the thousands of petitions it receives each year.

Legal scholars said Thursday that the case is unlikely to make it there because the dispute over the Rams’ contract is primarily a local issue, not a constitutional question.

“Usually, the Supreme Court takes cases that have meaning in other circumstances,” said John Drobak, a professor at the Washington University School of Law. “I’d be surprised if the Supreme Court would get involved in something so narrow.”

Resolving the dispute, Drobak said, “won’t affect anybody except us in St. Louis. It’s so specific.”
