Okla. Stat. tit. 52, § 52-111: Collateral attack on orders, rules and regulations -

Appeals - Supreme Court.

No collateral attack shall be allowed upon orders, rules and

regulations of the Commission made hereunder, but the sole method of

reviewing such orders and inquiring into and determining their

validity, justness, reasonableness or correctness shall be by appeal

from such orders, rules or regulations to the Supreme Court. On

appeal every such order, rule or regulation shall be regarded as

prima facie, valid, reasonable and just. No court of this state

except the Supreme Court, and it only on appeal, as herein provided,

shall have jurisdiction to review, reverse, annul, modify or correct

any order, rule, or regulation of the Commission within the general

scope of its authority herein or to enjoin, restrain or suspend

execution or operation thereof, provided that writs of mandamus and

prohibition shall lie from the Supreme Court to the Commission in

all cases where such writs, respectively, would under like

circumstances lie to any inferior court or officer.
