Robert H. Jackson, Doremus v. Board of Education…
“ If appellants established the requisite special injury necessary to a taxpayer's case or controversy, it would not matter that their dominant inducement to action was more religious than mercenary. It is not a question of motivation but of possession of the requisite financial interest that is, or is threatened to be, injured by the unconstitutional conduct. We find no such direct and particular financial interest here. If the Act may give rise to a legal case or controversy on some behalf, the appellants cannot obtain a decision from this Court by a feigned issue of taxation. ”
