(2) Any such proposed contract shall be filed with the commission within 90 days of execution of the contract. The contract shall be deemed to be executed on the date the parties sign a written contract or on the date the parties begin to transact business under the contract, whichever date is earlier. The commission shall promptly investigate and act upon the contract in accordance with ORS 757.495 (3) and (6).
(3) In making such investigation the commission and accountants, examiners and agents, appointed by the commission for the purpose, shall be given free access to all books, books of account, documents, data and records of the public utility as well as of the corporation with which it is proposing to contract, which the commission may deem material to the investigation. The failure or refusal of either of the parties to the proposed contract to comply with this subsection is prima facie evidence that such contract is unfair, unreasonable and contrary to public interest, and is sufficient to justify a determination and finding of the commission to that effect, which has the same force and effect as any other determination or order of the commission.
