(a) Grounds for suspension or termination
If the Secretary finds that an order, or any provision of the order, obstructs or does not tend to effectuate the policy of this chapter specified in section 7801(b) of this title, the Secretary shall terminate or suspend the operation of the order or provision under such terms as the Secretary determines are appropriate.

(b) Effect of lack of approval of order
If, as a result of a referendum, the Secretary determines that the order is not approved, the Secretary shall, within 180 days after making the determination, suspend, or terminate, as appropriate, collection of assessments under the order, and suspend or terminate, as appropriate, activities under the order in an orderly manner as soon as possible.
