A federal judge has tossed out a $37.3 million trade secrets verdict for Lockheed Martin Corp. and ordered a new trial after finding that the aircraft company failed to turn over to a defendant competitor documents critical to the case.

U.S. District Judge Charles A. Pannell Jr. on March 31 ordered the new trial at the request of Texas military contractor L-3 Communications Integrated Systems, the defendant in the five-year-old case. Pannell said it was “probable” that the outcome of the trial would have been different if the jury had been given access to the information that Lockheed withheld.
