Susquehanna Power Co. v. State Tax Comm'n of Md. (No. 1)

Background

A private power company that held a federal license built a dam on the Susquehanna River and created a pooled reservoir that submerged nearby land, including a town site and canal. The company acquired large areas of riverbed and upland by purchase and by grant from the State. For 1929, the State Tax Commission assessed 2,110 acres of those submerged lands at $2,349,300. The company sued, arguing the lands and their increased value were effectively immune from state tax because of the federal license and the waters of the river.

Reasoning

The Court addressed whether privately owned land used in a federally licensed power project becomes immune from state taxation. The Justices explained that a federal license or franchise may be protected, but the privately owned property used in a commercial business is not automatically taxed-free. The Court accepted the state’s valuation as neither excessive nor discriminatory on this record and rejected the company’s attempt to split the land’s value into parts attributable to the federal license or to the river itself. The upshot was that the State may tax the privately owned submerged land used in the power project.

Real world impact

This decision lets states continue to assess and tax privately owned riverbed and adjacent lands when those lands are used in commercial power projects, even if a federal license made that use possible. Property owners cannot avoid local taxation simply by saying part of their land’s value comes from a federal license or from the presence of navigable waters. The ruling affirms ordinary state valuation practices for commercial property used in power generation.
