The U.S. Supreme Court on Monday continued its streak of pro-arbitration rulings, reaffirming in a closely watched nursing home case that states may not impose rules that single out, overtly or otherwise, arbitration agreements for negative treatment.

The 7-1 ruling came in Kindred Nursing Centers v. Clark, a seemingly narrow case that could have broader ramifications for the nursing home industry in particular and businesses in general that look to the Federal Arbitration Act to protect arbitration agreements from invalidation under state laws.
