Whether harm to aesthetic, environmental, and recreational interests can constitute an injury in fact for APA standing.
Holding
Yes. Environmental and aesthetic harm can qualify as injury in fact; economic injury is not the exclusive basis for standing.
Reasoning
The Court relied on Data Processing and Barlow, which require a plaintiff seeking APA review to allege injury in fact and an interest arguably within the zone protected or regulated by the relevant statutes. Those cases had involved economic injuries, but the Court rejected any implication that only economic interests count.
A person's aesthetic and environmental well-being are important parts of quality of life. Thus, damage to the scenery, ecology, and recreational character of Mineral King and Sequoia National Park could support standing for people who actually use those places and whose enjoyment would be diminished. The fact that many people may share an environmental interest does not make it legally insignificant.
