Okla. Stat. tit. 12A § 2-724
Whenever the prevailing price or value of any goods regularly bought and sold in any established commodity market is in issue, reports in official publications or trade journals or in newspapers or periodicals of general circulation published as the reports of such market shall be admissible in evidence. The circumstances of the preparation of such a report, may be shown to affect its weight but not its admissibility.
Okla. Stat. tit. 12A, § 2-724
Oklahoma Code Comment
This changes the Oklahoma law, and permits the introduction of evidence previously inadmissible as hearsay. Private reports and the like have previously been inadmissible in Oklahoma. Ferriman v. Turner, 99 Okl. 277, 227 P. 443 (1924); Lash v. Ten Eyck,157 P. 924 (1916); Gulf Oil Corp. v. Miller, 198 Okl. 54, 175 P.2d 335 (1947). In Midland Valley R. Co. v. Adkins, 36 Okl. 15, 127 P. 867 the court did permit a person experienced in cattle shipments, and who accompanied the cattle on the occasion in question, to testify as to the state of the market, based upon information gathered from other commission men and from reading the market reports. The Commercial Code, however, makes the market reports themselves admissible, which goes beyond the Midland Valley case.
