Okla. Stat. tit. 85A, § 85A-3: Applicability of act

A. Every employer and every employee, unless otherwise

specifically provided in this act, shall be subject and bound to the

provisions of the Administrative Workers' Compensation Act and every

employer shall pay or provide benefits according to the provisions

of this act for the accidental injury or death of an employee

arising out of and in the course of his or her employment, without

regard to fault for such injury, if the employee's contract of

employment was made or if the injury occurred within this state. If

an employee makes a claim for an injury in another jurisdiction, the

employee is precluded from his or her right of action under the

Administrative Workers' Compensation Act unless the Workers'

Compensation Commission determines that there is a change in

circumstances that creates a good cause to bring the claim under the

Administrative Workers' Compensation Act; provided, however, that

the employee may not receive duplicate benefits to those received in

the foreign jurisdiction and the employee's right to bring a claim

under this act shall be subject to the limitations period for

bringing a claim pursuant to paragraph 1 of subsection A of Section

69 of this title. Nothing in this act shall be construed to

conflict with any valid Act of Congress governing the liability of

employers for injuries received by their employees.

B. The State of Oklahoma accepts the provisions of the Acts of

Congress designated as 40 U.S.C., Section 3172, formerly 40 U.S.C.,

Section 290, and hereby extends the territorial jurisdiction of the

Administrative Workers' Compensation Act of this state to all lands

and premises within the exterior boundaries of this state which the

Government of the United States of America owns or holds by deed or

act of cession, and to all purchases, projects, buildings,

constructions, improvements and property within the exterior

boundaries of this state belonging to the Government of the United

States of America, in the same manner and to the same extent as if

the premises were under the exclusive jurisdiction of this state,

subject only to the limitations placed thereon by the Acts of

Congress.

C. The Administrative Workers' Compensation Act shall apply

only to claims for injuries and death based on accidents which occur

on or after February 1, 2014.

D. The Workers' Compensation Code in effect before February 1,

2014, shall govern all rights in respect to claims for injuries and

death based on accidents occurring before February 1, 2014.
