Okla. Stat. tit. 12, § 12-577.1: Oklahoma Uniform Jury Instructions - Institution of

Inasmuch as many judgments in actions tried by juries are set

aside and vacated on account of errors in instructions; and,

whereas, justice is withheld, delayed, and, in some cases, denied on

account of such erroneous instructions; and, the compilation and

adoption of a body of uniform instructions in civil and criminal

cases tried by juries in the courts of this state is necessary to

the equal and uniform administration of justice; and, whereas, the

justices and judges of the appellate courts of this state are in the

best position to properly prescribe such instructions on this

subject to the Legislature; the Supreme Court of the State of

Oklahoma and the Court of Criminal Appeals of Oklahoma are

respectively requested and authorized to proceed to prescribe and

institute uniform instructions to be given in jury trials of civil

or criminal cases, such instructions to be called: "Oklahoma

Uniform Jury Instructions." (OUJI).
