Case Results

  • Benjamin I. Siminou, Partner, and Jonna D. Lothyan, Senior Counsel, of Singleton Schreiber obtained an order granting a new trial in Hardin v. Luke, a personal injury action arising from a motor vehicle collision. The court determined that defense counsel misconduct contributed to an inadequate damages award in the original trial. As a result, the prior damages finding was set aside and a new trial was ordered. The ruling reflects the firm’s commitment to ensuring fair proceedings and full accountability in personal injury litigation.
