Okla. Stat. tit. 17, § 17-186: Validation of securities or liens when certificate not

obtained.

Securities issued or liens created by any public utility, for

the issuance or creation of which a certificate should have been,

but through excusable neglect or mistake was not, applied for, may

be validated by the Commission upon application of such public

utility, signed and verified by the president or vice-president and

setting forth the information required by Section 5, and in addition

thereto a concise statement of the reasons why such application was

not made at the time such securities were issued or lien created. If

the Commission shall find and determine that such failure to make

application was due to excusable neglect or mistake, and was not

occasioned by any design to evade compliance with the law, and that

such issue or creation was otherwise in accordance with law, the

Commission shall issue to the corporation a validating certificate.
