CINCINNATI - The Sixth Circuit U.S. Court of Appeals on May 16 upheld summary judgment for an automobile manufacturer named as the defendant in a personal injury action, agreeing that the plaintiffs failed to show that a dangerous manufacturing flaw existed that allowed the defendant's sport utility vehicle to unintentionally accelerate (Linda Buck, et al. v. Ford Motor Co., No. 12-3908, 6th Cir.; 2013 U.S. App. LEXIS 9998).
