Paslay v. A&B Irrigation DistrictAnnotate this Case
At issue in this matter was landowners’ recourse against an irrigation district for diverting a portion of their water source to other landowners within the district. The appellants-landowners owned farms in Jerome County; A&B Irrigation District (the “District”) distributed water to these farms and others throughout its service area in Jerome and Minidoka Counties. The District serves two distinct sub-areas in its district: Unit A and Unit B. The water the District distributes comes from two sources: (1) surface water from the Snake River and associated reservoirs, and (2) groundwater from the Eastern Snake Plain Aquifer. These two water sources were historically what separated Units A and B, and many owners based their land choices in the 1950s on the water source. Unit A farms have received surface water exclusively since the District’s inception. For decades Unit B farms received only groundwater, but the District converted approximately 1400 Unit B acres to surface water in the 1990s in response to decreasing groundwater supply. Appellants claimed the Project primarily benefited Unit B landowners at the expense of Unit A by diverting a portion of Unit A’s sole water source (surface water) onto Unit B land and “diluting” their annual water supply. Additionally, the District divided Project costs equally among all landowners despite what Appellants claim was the Project’s primary purpose: to help sustain Unit B farms as their groundwater supply continues to decline. The landowners brought an action for a declaratory judgment regarding their constitutional water and property rights. They also sought injunctive relief against the irrigation district for a breach of fiduciary duty. The district court granted the irrigation district’s motion to dismiss on all three of the landowners’ claims. The landowners’ appeal centered on two issues with respect to their three claims against the District: the legal standard under which the district court dismissed Appellants’ claims, and the court’s substantive determinations under that standard. Appellants contend the district court erred both procedurally and substantively in dismissing all three counts in its amended complaint. Procedurally, they claimed the district court improperly considered matters outside the pleadings in dismissing all three claims under Rule 12(b)(6), rather than converting to the Rule 56 summary judgment standard. Substantively, Appellants contended that Counts I and III were justiciable as presented on the face of their amended complaint, and that res judicata did not bar relief under Count II. The Idaho Supreme Court found after review that the landowners failed to demonstrate justiciable claims in their Counts I and III, and that the district court erred in dismissing their property rights claim in Count II by considering matters outside the pleadings under Rule 12(b)(6).
