How it applies
Common Examples
6
Congress Regulates Interstate Water Shipments
Wade Watson operates a bottling plant in State A that ships purified water across state lines to retailers in State B. Congress enacts a uniform tax on such shipments to fund national infrastructure. Wade challenges the tax as nonuniform. The court upholds the levy because the constitutional grant of power to tax and regulate commerce among the states authorizes the measure when applied evenly nationwide.
Water Rights Fall Outside Servitude Rules
Willow Walker owns riparian land along a river and holds rights to divert water for irrigation under state prior-appropriation doctrine. A neighbor claims the diversion creates a servitude burdening his downstream parcel. The court rejects the claim because water-allocation doctrines are expressly excluded from the definition of servitudes.

Beachfront Ban Eliminates All Water-Adjacent Use

Common questions
Frequently Asked
3
Does water doctrine create a servitude under the Restatement?+
No. The Restatement expressly excludes rights determined by riparian, littoral, prior-appropriation, or ground-water doctrines from the definition of servitudes.
Supporting sources
When may a court order sale instead of partition because of water rights?+
A court may order sale when regulations prevent fair physical division of water access, such as when a single authorized well cannot be duplicated or separated from the farm unit, leaving any divided parcel unusable for agriculture.
Supporting sources
Does subdivision of a dominant estate apportion water-easement rights?+
Yes. Each subdivided parcel automatically receives the same privileges of use authorized by the original easement, and the easement runs to the land rather than to any single owner.
