Notes of Federal Advisory Committee on Rules - 1997Amendment
The amendment to Rule 407 makes two changes in the rule.First, the words ''an injury or harm allegedly caused by'' were added toclarify that the rule applies only to changes made after the occurrence thatproduced the damages giving rise to the action. Evidence of measures taken bythe defendant prior to the ''event'' causing ''injury or harm'' do not fallwithin the exclusionary scope of Rule 407 even if they occurred after themanufacture or design of the product. See Chase v. General Motors Corp., 856F.2d 17, 21-22 (4th Cir. 1988).
Second, Rule 407 has been amended to provide that evidenceof subsequent remedial measures may not be used to prove ''a defect in aproduct or its design, or that a warning or instruction should have accompanieda product.'' This amendment adopts the view of a majority of the circuits thathave interpreted Rule 407 to apply to products liability actions. See Raymondv. Raymond Corp., 938 F.2d 1518, 1522 (1st Cir. 1991); In re Joint EasternDistrict and Southern District Asbestos Litigation v. Armstrong WorldIndustries, Inc., 995 F.2d 343 (2d Cir. 1993); Cannv. Ford Motor Co., 658 F.2d 54, 60 (2d Cir. 1981), cert. denied, 456 U.S. 960(1982); Kelly v. Crown Equipment Co., 970 F.2d 1273, 1275 (3d Cir. 1992);Werner v. Upjohn, Inc., 628 F.2d 848 (4th Cir. 1980), cert. denied, 449 U.S.1080 (1981); Grenada Steel Industries, Inc. v. Alabama Oxygen Co., Inc., 695F.2d 883 (5th Cir. 1983); Bauman v. Volkswagenwerk
Although this amendment adopts a uniform federal rule, itshould be noted that evidence of subsequent remedial measures may be admissiblepursuant to the second sentence of Rule 407. Evidence of subsequent measuresthat is not barred by Rule 407 may still be subject to exclusion on Rule 403grounds when the dangers of prejudice or confusion substantially outweigh theprobative value of the evidence.
