We reverse and remand. This controversy was previously before us in Orr v. Kneip, 260 N.W.2d 638 (S.D. 1977), hereinafter referred to as Orr I. The facts are set forth fully in that opinion and will not be repeated here at length. In summary, plaintiffs, respondents herein, brought this action against the subdistrict challenging the constitutionality of the apportionment of the subdistrict's board of directors.
