Supreme Court of the United States
Kansas v. Colorado
December 7, 2004543 U.S. 86
Summary
The Court overruled Kansas' exceptions to the Special Master's Fourth Report, rejecting the appointment of a River Master, confirming prejudgment interest runs from 1985 on damages accrued after that date, upholding a 10-year measurement period for future compliance, and allowing the Colorado Water Court to initially determine replacement credits. Justice Thomas concurred in part and in the judgment, arguing no prejudgment interest is warranted, while Justice Stevens concurred in part and dissented in part, arguing interest should accrue on all damages known since 1969.
