Kansas v. Nebraska
The Court issued a formal decree implementing its earlier ruling in the water dispute between Kansas and Nebraska over the Republican River Compact, spelling out exact dollar amounts, accounting rule changes, and cost-sharing among the states.
This decree finalizes the practical details left after the Court's opinion on the merits, ordering Nebraska to pay Kansas $5.5 million and revising how future water use will be measured going forward.
How it got here: The Court exercised original jurisdiction, a Special Master tried the issues and reported, the Court ruled on exceptions to that report, and now issues this implementing decree.
The Case in Depth
What happened
Kansas sued Nebraska and Colorado in the Supreme Court's original jurisdiction over shared use of water under the Republican River Compact, alleging Nebraska overconsumed its allocated share. A Special Master heard the evidence and issued a report; the Court then ruled on the merits in a separate opinion, Kansas v. Nebraska, 574 U.S. ___ (2015).
The question before the Court
After the Court ruled on Kansas and Nebraska's water-sharing dispute over the Republican River, what exactly must each state now do?
Why it matters
This decree turns the Court's earlier legal ruling into concrete, enforceable terms: Nebraska must pay Kansas a specific sum, revised accounting rules will govern how the three states measure water use for years to come, and costs of the litigation are divided among Kansas, Nebraska, and Colorado.
What changes now
This decree is the final disposition of the original-jurisdiction dispute; Nebraska must pay Kansas $5.5 million within 60 days, and the revised accounting procedures apply going forward starting with Compact Year 2007. The Court retains jurisdiction to enter further orders if needed to enforce the decree, but no further merits proceedings are contemplated.
How the Court got there
The legal reasoning, step by step
- The decree implements the legal conclusions already reached in the Court's companion opinion on the merits, Kansas v. Nebraska, rather than announcing new legal reasoning of its own.
- It reforms the RRCA Accounting Procedures used to measure each state's water consumption under the Compact, applying the corrected accounting methodology going forward.
- It resolves specific factual disputes flagged in the Special Master's report, such as whether Nebraska is liable for evaporative losses from a particular reservoir and whether evaporation from non-federal reservoirs counts as consumptive use.
- Based on the corrected accounting, the decree fixes the precise amount by which Nebraska exceeded its allocation and sets the resulting monetary payment owed to Kansas.
- The decree allocates responsibility for the Special Master's fees and costs among the three states and closes out all other claims and requests for relief with prejudice.
