Okla. Stat. tit. 52, § 52-64: Suspension of penalty, when

Whenever the operation of a valid order of a competent court or

the Corporation Commission is duly suspended, according to law, the

punitive provisions of this article shall likewise be suspended in

their operation as to the transactions adjudicated in said court;

and, further, any court having jurisdiction of an action brought by

the state to punish for a violation under the terms of this article,

shall not impose a punishment therefor greater than Five Hundred

Dollars ($500.00) against any person or corporation, if it finds

from the evidence that the violation was made solely with the object

of testing according to law the validity of any of the provisions of

this article, or of the order of any competent court or of the

Corporation Commission, in any proceeding to carry out the

provisions hereof.
