However, except in the case of fraud or willful evasion, or the inaccessibility of books and records for audit or with the express consent of the person audited, no notice of a deficiency or assessment shall be issued by the Secretary for more than 3 registration years. This limitation shall commence on any January 1 as to calendar year registrations and on any July 1 as to fiscal year registrations. This limitation shall not apply for any period during which the person affected has declined or refuses to make his books and records available for audit, nor during any period of time in which an Order of any Court has the effect of enjoining or restraining the Secretary from making an audit or issuing a notice. Notwithstanding, each person licensed under the International Registration Plan and audited by this State or any member jurisdiction shall follow the assessment and refund procedures as adopted and amended by the International Registration Plan members. The Secretary of State shall have the final decision as to which registrants may be subject to the netting of audit fees as outlined in the International Registration Plan. Persons audited may be subject to a review process to determine the final outcome of the audit finding. This process shall follow the adopted procedure as outlined in the International Registration Plan. All decisions by the IRP designated tribunal shall be binding.
