Practice Tip: Firing Your Expert

During a recent product liability trial, the plaintiff's expert opined in his original disclosure that the subject machine was defective because it lacked a clutch safety mechanism. Trial counsel, retained just weeks before jury selection, learned from the same expert that no machine in the industry contains such a mechanism. They concluded that cross-examination of the expert on this point would probably outweigh any benefit that such testimony might add to the plaintiff's case, and that a simpler explanation for the accident was the manufacturer's failure to place conspicuous warnings to the user on how to operate the device properly. They decided that it would be wise to have the expert testify about the missing warnings instead of the design defect. The problem was that the expert's design defect theory had been presented in the plaintiff's pretrial disclosure statement, which had been served on the defendants, but nothing was disclosed about the failure to warn.
