To establish Article III standing, a plaintiff must show it has suffered or is likely to suffer an injury in fact and causation–that the injury in fact is caused by the defendant’s allegedly wrongful act and therefore is redressable by injunction or damages. Causation is simply established when the plaintiff challenges a government regulation that governs the plaintiff, but more difficult to show when the regulation applies only to others. In that situation, the plaintiff must be able to show a clear causal chain that does not depend on speculation about how third parties will react to the government regulation. Here, 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. Doctors won’t be forced to provide more emergency abortions because of federal and state “conscience” laws that allow and protect doctors from having to perform operations that are contrary to the religious or moral beliefs. There is no evidence that doctors will incur additional expense as a result of the broader availability of mifepristone and the causal chain is too attenuated from loosened regulation to additional third party health complications to more doctor visits. Medical associations also lack standing. They suffer no injury in fact from wider availability of mifepristone and cannot claim standing merely by spending money opposing the FDA’s actions. Havens Realty Corp. v. Coleman, 455 U. S. 363, 379, n. 19 (1982) does not stand for the broad proposition that standing exists when an organization diverts its resources in response to a defendant’s actions. What led to standing in Havens was the fact that the false information given HOME’s black testers impaired Home’s core business activities of home counseling and referral. Havens was unusual and is not to be extended beyond its context.
