Holding: Had standing. The question of standing is different and involves, apart from the “case or controversy” test, concerns whether the interest sought to be protected by the ? is arguably within the zone of interest to be protected or regulated by the statute or constitutional guarantee in question. Thus, the Administrative Procedure Act grants standing to a person “aggrieved by agency action within the meaning of the relevant statute.” That interest may reflect “aesthetic, conservational, and recreational” as well as economic values.
