In Kaiser Aetna v. United States, 444 U.S. 164 (1979), a case won by my Damon Key partners Charlie Bocken and Diane Hastert, the Court held the navigational servitude does not create a “blanket exception to the Takings Clause whenever Congress exercises its Commerce Clause authority to promote navigation.” The servitude gives the public a right of access to waters that intheir natural condition are actually navigable, and absolves thefederal government from liability for compensation when land subject tothe servitude is taken or damaged, the the theory being that navigablewaters are not part of a riparian or littoral owner’s “bundle ofrights” —
The navigational servitude is an expression of the notion that the determination whether a taking has occurred must take into consideration the important public interest in the flow of interstate waters that in their natural condition are in fact capable of supporting public navigation. See
