“The causation requirement is central to Article III standing. Like the injury in fact requirement, the causation requirement screens out plaintiffs who were not injured by the defendant’s action. Without the causation requirement, courts would be ‘virtually continuing monitors of the wisdom and soundness’ of government action."
“The plaintiffs do not allege the kinds of injuries described above that unregulated parties sometimes can assert to demonstrate causation. Because the plaintiffs do not prescribe, manufacture, sell, or advertise mifepristone or sponsor a competing drug, the plaintiffs suffer no direct monetary injuries from FDA’s actions relaxing regulation of mifepristone. Nor do they suffer injuries to their property, or to the value of their property, from FDA’s actions. Because the plaintiffs do not use mifepristone, they obviously can suffer no physical injuries from FDA’s actions relaxing regulation of mifepristone. Rather, the plaintiffs say that they are pro-life, oppose elective abortion, and have sincere legal, moral, ideological, and policy objections to mifepristone being prescribed and used by others. The plaintiffs appear to recognize that those general legal, moral, ideological, and policy concerns do not suffice on their own to confer Article III standing to sue in federal court. So to try to establish standing, the plaintiffs advance several complicated causation theories to connect FDA’s actions to the plaintiffs’ alleged injuries in fact.”
“In sum, the doctors in this case have failed to establish Article III standing. The doctors have not shown that FDA’s actions likely will cause them any injury in fact. The asserted causal link is simply too speculative or too attenuated to support Article III standing.”
