It is rare that a plaintiff will have direct evidence of how a specific product later involved in an accident was manufactured and assembled. While the manufacturing and assembly process may be documented to an extent, proof of defect at the time of manufacture is usually nonexistent. The Mississippi Supreme Court has recognized that "direct proof of a [manufacturing] defect at the time the product left the possession of the manufacturer is seldom available." BF Goodrich, Inc. v. Taylor, 509 So. 2d 895, 903 (Miss. 1987). Accordingly, the Court allows the existence of a defect at this crucial time to be proven by circumstantial evidence. Id. The Court has also held that, in cases depending on circumstantial evidence, summary judgment should rarely be granted. Id. "Rarely" does not mean "never," and evidence can be developed that will support summary judgment or persuasive defenses at trial.
