8.3      Answers in Social Security cases - In all Social Security cases filed under 42 U.S.C. §§ 405(g) and 1383(c)(3), defendant shall have sixty (60) days after notification of the commencement of the action to file and serve upon plaintiff a certified copy of the administrative record of the proceedings, which shall constitute defendant’s answer, or otherwise move against the complaint. No separate answer need be filed.  Unless the court sets a different time, servicing a motion under Federal Rules of Civil Procedure 12 alters the time to answer as provided by Federal Rules of Civil Procedure 12(a)(4).
