§ Rule 407. Subsequent remedial measures

Rule 407. Subsequent remedial measures

When, after an injury or harm allegedly caused by an event, measures are taken which, if taken previously, would have made the injury or harm less likely to occur, evidence of the subsequent measures is not admissible to prove that the party who took the measures was negligent or engaged in culpable conduct, or produced, sold, designed, or manufactured a product with a defect or a need for a warning or instruction. This rule does not require the exclusion of evidence of subsequent measures when offered for impeachment, or to prove other matters, if controverted, such as ownership, control, or feasibility of precautionary measures.

Comment: Pa.R.E. 407 is substantially the same as F.R.E. 407. The wording has been modified in order to clarify two ambiguities in the federal formulation.

The first sentence of Pa.R.E. 407 makes clear that the rule of exclusion favors only the party who took the subsequent remedial measures. Though F.R.E. 407 is silent on the point, the courts have generally held that the federal rule does not apply when one other than the alleged tortfeasor takes the action because the reason for the rule (to encourage remedial measures) is not then implicated. See, e.g., TLT-Babcock, Inc. v. Emerson Electric Co., 33 F.3d 397, 400 (4th Cir. 1994) (collecting cases).

The last sentence of Pa.R.E. 407 makes clear that the rule's exception for evidence that is offered to prove matters such as ownership, control, or feasibility of precautionary measures, applies only when those issues are controverted. Though the federal rule, as worded, can be construed to mean that only feasibility need be controverted, the cases have generally interpreted it to mean that any issue for which evidence is admitted under the rule's exception must be controverted. See, e.g., Hall v. American Steamship Co., 688 F.2d 1062, 1066-67 (6th Cir. 1982); Hull v. Chevron U.S.A., Inc., 812 F.2d 584, 586-87 (10th Cir. 1987).

Duchess v. Langston Corp., 564 Pa. 529, 769 A.2d 1131 (2001), is a case dealing with the admissibility of evidence of subsequent remedial measures in a strict product liability case, and, in particular, the applicability of exceptions to the rule of exclusion when the evidence is offered to prove feasibility of precautionary measures, or to impeach the credibility of a witness.

The original wording of Pa.R.E. 407 applied to negligence cases, but, like the original wording of F.R.E 407, left open whether it applied to strict product liability cases. In Duchess v. Langston Corp., 564 Pa. 529, 769 A.2d 1131 (2001), the Supreme Court held that it did. The rule was amended to make this clear.
