Warranties whether express or implied shall be construed as consistent with each other and as cumulative, but if such construction is unreasonable the intention of the parties shall determine which warranty is dominant. In ascertaining that intention the following rules apply:
Okla. Stat. tit. 12A, § 2-317
Oklahoma Code Comment
There are no previous comparable Oklahoma statutes or decisions on paragraphs (a) and (b). Previous Oklahoma law is in accord with the first part of paragraph (c), Fairbanks, Morse & Co. v. Miller, 80 Okl. 265, 195 P. 1083 (1921), but contra to the exclusion of the warranty of fitness for a particular purpose from the rule. In Goldstein v. Welded Products Co., 196 Okl. 219, 164 P.2d 229 (1946) the purchaser attempted to prove an implied warranty of fitness which was in conflict with the express warranty. The court held this proof inadmissible as in violation of the parol evidence rule. The Commercial Code reverses this decision.
