We are amending our rules regarding service of legal process in lawsuits involving judicial review of Agency final decisions on individual claims for benefits under titles II, VIII, and/or XVI of the Social Security Act (Act). Under the current rules, summonses and complaints in these types of cases are required to be sent to the Social Security Administration (SSA), Office of the General Counsel (OGC) in Baltimore, Maryland. These final rules provide that summonses and complaints in these types of cases shall be mailed directly to the OGC office that is responsible for the processing and handling of litigation in the particular jurisdiction in which the complaint has been filed. The names and addresses of those offices, and the jurisdictions for which they are currently responsible, are detailed in a separate notice in the Notices section of today's Federal Register. Future changes in the addresses and/or jurisdictional responsibilities of these offices will similarly be published in the Federal Register. Current procedures for service of summonses and complaints in all other types of cases filed against SSA, i.e., those that do not involve judicial review of Agency final decisions on individual claims for benefits under titles II, VIII, and/or XVI of the Act, are not affected by this change.
