The state’s second-highest court on Wednesday reversed a lower-court ruling that supported Hofstra University’s lawsuit to keep Nassau County from leasing its 72-acre Coliseum site to a Las Vegas casino company.

New York State Appellate Division, Second Judicial Department, issued a three-page ruling that brings the legal battle between Hofstra and the county back down to Nassau County Supreme Court, requiring more information and asking that Las Vegas Sands, based in Nevada, be included in the lawsuit.
