United States v. Liu

by
Defendant challenged his conviction for conspiracy to steal trade secrets and perjury. The Government contended that defendant, who worked on research and development, conspired to steal Dow Chemical's trade secrets regarding a type of chlorinated polyethylene (CPE) and sell that information to Chinese companies for his own profit. The principal issue on appeal concerned the propriety of the court's ruling excluding the testimony of defendant's engineering expert. Because of the witness's training and experience as a chemical engineer and his broad experience in chemical plants, the court concluded that the district court abused its discretion in excluding his opinion testimony related to the manufacturing of CPE. However, given the overwhelming evidence that defendant and his co-conspirators stole trade secrets and that defendant believed he was stealing trade secrets, the court concluded that the exclusion of the witness's testimony did not affect the verdict. Further, there was sufficient evidence to support defendant's perjury conviction. Accordingly, the court affirmed the judgment. View "United States v. Liu" on Justia Law
