Okla. Stat. tit. 20, § 20-98: Decision of cases pending on change of district

In any county detached from one judicial district and added to

another, if there be any case pending in the district court of such

county which has at any time been tried by the judge of said court,

and by him taken under advisement, and still undecided, it shall be

the duty of the judge who tried said cause to make and render his

finding and judgment therein and to determine all the motions

therein, and to allow and settle the case made therein or dispose of

such case in all respects as though said county had not been

detached from his district.
