(Carson City, NV) — The Nevada Supreme Court heard arguments yesterday on a petition to build a sports arena on the Las Vegas Strip. Supporters of the 18,000 seat stadium say the measure is legally sound. But an opposition group claims the petition should be disqualified, because backers used false information to gather the signatures. If it lands on the November ballot, voters would decide whether a sales and use tax on the Vegas Strip should pay for the arena. Justices are expected to rule at a later date.
