Summary

Robert H. Jackson United States v. Willow River Power Company…

But that a closed catalogue of abstract and absolute 'property rights' in water hovers over a given piece of shore land, good against all the world, is not in this day a permissible assumption. We cannot start the process of decision by calling such a claim as we have here a 'property right'; whether it is a property right is really the question to be answered. Such economic uses are rights only when they are legally protected interests.

Robert H. Jackson United States v. Willow River Power Company…

The Fifth Amendment, which requires just compensation where private property is taken for public use, undertakes to redistribute certain economic losses inflicted by public improvements so that they will fall upon the public rather than wholly upon those who happen to lie in the path of the project. It does not undertake, however, to socialize all losses, but those only which result from a taking of property.

Robert H. Jackson United States v. Willow River Power Company…

Rights, property or otherwise, which are absolute against all the world are certainly rare, and water rights are not among them. Whatever rights may be as between equals such as riparian owners, they are not the measure of riparian rights on a navigable stream relative to the function of the Government in improving navigation. Where these interests conflict they are not to be reconciled as between equals, but the private interest must give way to a superior right, or perhaps it would be more accurate to say that as against the Government such private interest is not a right at all.
