As previously reported here, the Federal Trade Commission (FTC) is currently scheduled to commence enforcement of the FACTA Red Flags Rule (72 Fed. Reg. 63,718) on June 1, 2010. On Friday, only 10 days before the deadline, the American Medical Association, the American Osteopathic Association, and the Medical Society for the District of Columbia filed suit against the FTC in the United States District Court for the District of Columbia (AMA v. FTC, D.D.C., No. 1:10-cv-00843), following in the footsteps of similar lawsuits filed in the past year by the American Bar Association (ABA) and the American Institute of Certified Public Accountants (AICPA). The ABA, in a lawsuit filed last August (ABA v. FTC, No. 1:09-cv-01636-RBW), succeeded in obtaining an order (now on appeal) barring the FTC from enforcing the Red Flags Rule against lawyers. (There has been no ruling on the AICPA complaint filed last November.) Following is a discussion of the definitions ("creditor" and "credit") at the heart of the dispute, a summary of the positions taken by the FTC and the AMA with respect to application of the Red Flags Rule to physicians, and a brief review of the court's decision in ABA v. FTC.
