Wis. Stat. § 402.719
A commercial contract clause that limited consequential damages was unconscionable. Trinkle v. Schumacher Co., 100 Wis. 2d 13, 301 N.W.2d 255 (Ct. App. 1980). The remedy under sub. (2) was proper when a damage clause provided damages that were, under the circumstances, unconscionably low. Phillips Petroleum v. Bucyrus-Erie Co., 131 Wis. 2d 21, 388 N.W.2d 584 (1986). A purchaser cannot claim that a warranty provision has failed of its essential purpose merely because a potential claim did not arise until after the warranty period had expired. Wisconsin Power & Light v. Westinghouse Elec., 830 F.2d 1405 (1987). In interpreting subs. (2) and (3), the Wisconsin Supreme Court has adopted the "dependent approach." Under the dependent approach, if a litigant proves a limited remedy fails of its essential purpose under sub. (2), any accompanying consequential damages disclaimer is per se unconscionable under sub. (3). Sanchelima International, Inc. v. Walker Stainless Equipment Co., 920 F.3d 1141 (2019). A damage disclaimer is not enforceable if the remaining exclusive remedy fails of its essential purpose. Rich Products Corp. v. Kemutec, Inc., 66 F. Supp. 2d 937 (1999).
