Barber v. Rochester green
wash · 1958

1960Quite recently, in Barber v. Rochester, 52 Wn. (2d) 691, 328 P. (2d) 711 , we reviewed the subject and concluded that the so-called parol evidence rule was not an exclusionary device but, on the contrary, was a basic tenet of substantive law and the trial court’s duty was to consider all relevant extrinsic evidence, either oral or written, in order to determine if the writing embraced the entire agreement of the parties.

1960The majority has cited Barber v. Rochester, 52 Wn. (2d) 691, 328 P. (2d) 711 (1958) (in which I concurred), as supporting its holding that it was the trial court’s duty “to consider all relevant extrinsic evidence, either oral or written, in order to determine if the writing embraced the entire agreement of the parties.” Of course the parol evidence rule does not operate as an exclusionary device to preclude the conditional reception of evidence tending to indicate that an instrument does not embody certain subjects of negotiation.

First Farmers-Merchants Bank & Trust Co., 180 Wash. 440, 443 , 40 P.2d 144 (1935)): The actual rule ... is that all conversations and parol agreements between the parties prior to a written agreement are so merged therein that they cannot be given in evidence for the purpose of changing the contract or showing an intention or understanding different from that expressed in the written agreement.

1953Hicks & Son, 82 F. (2d) 277, quoted in Bond v. Wiegardt, 36 Wn. (2d) 41, 216 P. (2d) 196 ), logic would seem to require that it be consistent with the terms of the instrument, else the exception nullifies the parol evidence rule.
