Moe’s Southwest Grill founder Martin Sprock III spent eight years in federal court fighting fraud and racketeering allegations. Now that a federal judge has found no evidence to back up those claims, Sprock and the companies that were his co-defendants are asking the restaurant franchisees who sued them to reimburse them for more than $1.8 million in attorney fees.

But the legal battle between Sprock, Moe’s—known for the ‘Welcome to Moe’s” chorus with which its staff greet customers—and its franchisees may not be over yet. Miami attorney Robert Einhorn, one of the lawyers representing the franchisees, said the legal team is “evaluating an appeal” of U.S. District Judge Richard Story’s findings exonerating Sprock and Moe’s of any civil wrongdoing.
