Okla. Admin. Code § 230:35-9-9
The Secretary of the State Election Board shall be authorized to extend the provisional ballot verification period beyond 1 p.m. on Friday in the event that any County Election Board Secretary is unable to complete the verification of all provisional ballots by that time. In the event that the Secretary of the State Election Board extends the verification period beyond 1 p.m. on Friday, the period shall be extended statewide and no County Election Board shall release any information concerning provisional ballots until authorized to do so by the Secretary of the State Election Board. The time for contests of election and the time to certify the results of the election also shall be extended by the same number of hours or days, excluding Saturday and Sunday, as the verification period. For example, if the verification period is extended until 5 p.m. on Monday next following the election, the deadline for filing a contest of election shall be extended until 5 p.m. on Monday next following the election. In this example, the final election results would be certified no earlier than 5 p.m. on Monday next following the election.
