Montana v. Wyoming and North Dakota

Docket No. Argument Opinion Vote Author Term
22o137 Jan 10, 2011 May 2, 2011 7-1 Thomas OT 2010

Holding: Montana has failed to state a claim for breach of the Yellowstone River Compact. Wyoming's more efficient irrigation systems are permissible under the Compact as long as the water conserved by those systems is used to irrigate the same acreage watered in 1950.

Plain English Holding: Wyoming did not violate the Yellowstone River Compact by allowing Wyoming residents to implement more efficient irrigation systems on the farmland that existed when the compact was signed, even though the result is less water flowing downstream to Montana.

Judgment: Montana’s exception to the report of the Special Master overruled, 7-1, in an opinion by Justice Thomas on May 2, 2011. Justice Scalia filed a dissenting opinion. On February 20, 2018, the report of the Special Master was received and ordered filed, and the proposed judgment and decree were entered. Justice Kagan took no part in the consideration or decision of this case.

Feb 23 2015Report of the Special Master received and ordered filed. The Court notes that the Master has twice directed the parties to address whether the amount of damages at stake justifies further proceedings. The Master’s Report and the submissions of the parties indicate that fees and expenses could well exceed any recovery. The parties are therefore directed to consider carefully whether it is appropriate for them to continue invoking the jurisdiction of this Court. See Arizona v. California, 373 U. S. 546, 564 (1963) (“[W]e are mindful of this Court’s often expressed preference that, where possible, States settle their controversies by mutual accommodation and agreement.” (internal quotation marks omitted)). The Special Master is encouraged to facilitate efforts to resolve the parties’ dispute without the need for a damages proceeding, including by revisiting the arrangement for division of fees and expenses. Cf. Fed. Rule Civ. Proc. 68. If the parties elect to continue, exceptions to the Report, with supporting briefs, may be filed within 45 days. Replies, if any, with supporting briefs, may be filed within 30 days. Sur-replies, if any, with supporting briefs, may be filed within 30 days
