S.D. Codified Laws § 58-24-23

If the director shall find that an application pursuant to § 58-24-22 is made in good faith, that the applicant has a specific economic interest, that the applicant would be so aggrieved if his grounds are established, and that such grounds otherwise justify holding a hearing, he shall within thirty days after receipt of such application hold a hearing upon not less than ten days' written notice to the applicant and to every insurer and rating organization which made such filing.
