Okla. Stat. tit. 22, § 22-1086: Subsequent application

All grounds for relief available to an applicant under the Post-

Conviction Procedure Act, including claims challenging the

jurisdiction of the trial court, must be raised in his or her

original, supplemental or amended application. Any ground finally

adjudicated or not so raised, or knowingly, voluntarily and

intelligently waived in the proceeding that resulted in the

conviction or sentence or in any other proceeding the applicant has

taken to secure relief may not be the basis for a subsequent

application, unless the court finds a ground for relief asserted

which for sufficient reason was not asserted or was inadequately

raised in the prior application.
