The case is assigned to U.S. District Court Judge Sam Crow and U.S. Magistrate Judge Teresa J. James. McElroy's performed work on the Mars Wrigley property from Jan. 25 to May 25, 2018. In the lawsuit, McElroy's alleges breach of contract by Mars Wrigley, unjust enrichment against the defendant, and seeks enforcement of lien, the court filing said. Besides the $2.544 million, McElroy's also is seeking payment of interest, costs and attorneys fees in the action. The contract between McElroy's and Mars said the total amount due to the contractor for the project was $5.586 million, the lawsuit said. McElroy's has been paid $2.837 million by Mars Wrigley, which is slightly more than half the amount owed, the lawsuit said. McElroy's provides heating, air conditioning, and plumbing services. The jury trial to resolve the lawsuit is expected to start more than seven months from now, according to a court scheduling order.
