Sporhase v. Nebraska Ex Rel. Douglas

1982-07-02

Headline: Court strikes down Nebraska reciprocity rule blocking export of groundwater, ruling the reciprocal-permit requirement violates the Commerce Clause and limits a State’s ability to bar interstate water transfers.

Holding: The Court held that groundwater can be an article of interstate commerce and that Nebraska’s reciprocal-permit requirement for exporting groundwater violates the Commerce Clause.

Real World Impact:

Strikes down state reciprocity bans on exporting groundwater across state lines.
Affirms groundwater can be treated as interstate commerce subject to federal limits.
Leaves state conservation permit rules intact except the invalid reciprocity clause.

Topics: groundwater rules, interstate commerce, water permits, state conservation

Summary

Background

A pair of landowners own adjoining farms that straddle Nebraska and Colorado and pump groundwater from a well located on the Nebraska side to irrigate both their Nebraska and Colorado land. Nebraska law (§46-613.01) requires a permit to transport groundwater out of the State and conditions the permit on the neighboring State granting reciprocal rights. Nebraska sought to stop the owners from moving water across the border without a permit, and the Nebraska courts upheld the statute.

Reasoning

The Court considered three questions: whether groundwater can be treated as an article of interstate commerce, whether Nebraska’s rule unlawfully burdens interstate commerce, and whether Congress has authorized the States to impose such limits. The Court concluded that groundwater can be an article of commerce and that Nebraska’s conservation goals are legitimate. The Court found the statute’s first three permit conditions tied to conservation could be reasonable. But the reciprocity clause — which blocks exports unless the receiving State allows exports to Nebraska — was not narrowly related to conservation because it can bar transfers even when local supply is sufficient or the water’s best use is across the border. The Court therefore held the reciprocity requirement violates the Commerce Clause and reversed the Nebraska Supreme Court.

Real world impact

The decision limits a State’s ability to impose a blanket export ban based solely on whether a neighboring State reciprocates. Landowners and farmers who move water across state lines cannot be blocked by a facial reciprocity rule, though States may still require permits and deny them for legitimate conservation reasons. The Court left severability and other permit issues to state courts and noted Congress retains authority to regulate groundwater nationally.

Dissents or concurrances

Justice Rehnquist, joined by Justice O’Connor, dissented, arguing the Court should not assess congressional power or disturb Nebraska’s traditional sovereign authority over in‑state water use and that Nebraska’s restrictions did not violate the Commerce Clause.
