Whether Wildlife Preserves could invoke the prior-public-use doctrine to bar Texas Eastern from condemning a pipeline easement across the wildlife preserve.
Holding
No. Wildlife Preserves' private conservation use did not bar condemnation, and the Natural Gas Act authorized Texas Eastern to take land necessary for its federally certificated interstate pipeline.
Reasoning
The Natural Gas Act, enacted under Congress's commerce power, gives a certificated natural-gas company eminent-domain authority to acquire land necessary for its pipeline when it cannot obtain the land by agreement. That authority can extend to land already devoted to another public use when the new use is necessary to a paramount federal purpose.
Wildlife Preserves was a private nonprofit corporation, not a governmental agency or public utility with independent condemnation power. Although its conservation work served an important public-minded purpose, it therefore did not occupy the position of an existing public condemnor entitled to demand the ordinary prior-public-use comparison between competing public uses.
In any event, withholding land necessary for a federally authorized interstate pipeline on the basis of the preserve's existing use would frustrate the federal program Congress established through the Natural Gas Act. The preserve's use could not override that federally conferred condemnation authority.
