(a) Notwithstanding any other provision of the Act, any person who pays an assessment under the Act may demand and must promptly receive from the Council a refund of such assessment. A demand for refund must be made in accordance with procedures in the approved charter and within such time as will be prescribed by the Council and approved by NMFS. Procedures to provide such a refund must be established before any such assessment may be collected. Such procedures must allow any person to request a refund 90 days or more from such collection, and provide that such refund must be made within 60 days after demand for such refund is made.

(b) Once a refund has been requested by a sector participant and paid by the Council, that sector participant may no longer participate in a referendum or other business of the Council during the remainder of the assessment rate period. Future assessments will only be sent to such a sector participant at the request of the sector participant. If assessments are paid during a future assessment rate period and no refund is requested, that sector participant may again participate in a referendum or other business of the Council.
