Arizona School Tuition Organization v. Winn
The Supreme Court has ruled in the Arizona School Tuition Organization v. Winn case, holding that the plaintiffs lacked standing to bring a suit:
“For the reasons discussed below, respondents cannot take advantage of Flast’s narrow exception to the general rule against taxpayer standing. As a consequence, respondents lacked standing to commence this action, and their suit must be dismissed for want of jurisdiction.”
