CLEVELAND - In a case alleging that a neck brace defect caused a 16-year-old motocross rider's paralysis, a federal judge in Ohio on July 15 excluded two of four plaintiffs' causation and warnings experts and refused to exclude a causation defense expert and on July 17 granted the manufacturer partial summary judgment (S.S., et al. v. Leatt Corp., No. 1: 12 CV 483, N.D. Ohio, Eastern Div.; 2013 U.S. Dist. LEXIS 98366).
