den, “an adverse party may not rest upon the mere allegations or denials of the adverse party’s pleading, but the adverse party’s response, by affidavit or as otherwise provided in this Rule, must set forth specific facts showing that there is a genuine issue for trial.” Rule 56(e), Federal Rules of Civil Procedure; see also, Anderson v. Liberty Lobby, Inc., supra at 256, 106 S.Ct. 2505; Eddings v. City of Hot Springs, Ark., 323 F.3d 596, 602 (8th Cir.2003).
Moreover, the movant is entitled to Summary Judgment where the nonmoving party has failed “to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial.” Celotex Corp. v. Catrett, supra at 322, 106 S.Ct. 2548; see also, Forest Park II v. Hadley, 408 F.3d 1052, 1057 (8th Cir.2005); Mercer v. City of Cedar Rapids, 308 F.3d 840, 843 (8th Cir.2002); Hammond v. Northland Counseling Center, Inc., 218 F.3d 886, 891 (8th Cir.2000). No genuine issue of fact exists in such a case because “a complete failure of proof concerning an essential element of the nonmoving party’s case necessarily renders all other facts immaterial.” Celotex Corp. v. Catrett, supra at 323, 106 S.Ct. 2548; see also, Sallis v. University of Minnesota, 408 F.3d 470, 474 (8th Cir.2005); Davis v. U.S. Bancorp, 383 F.3d 761, 768 (8th Cir.2004); Bell Lumber and Pole Co. v. United States Fire Ins. Co., 60 F.3d 437, 441 (8th Cir.1995).
2. Legal Analysis. On January 25, 2008, the Plaintiff filed a Motion for Summary Judgment. See, Plaintiffs Motion for Summary Judgment, Docket No. 17. However, his Motion was plainly based upon what he deemed the Defendant’s failure to respond to the Complaint. Id. at p. ii (“Please take notice that this motion is made following *20 expired days from the date of the local U.S. Attorney’s Notice of Appearance; *21 expired days from the date of service of summons and complaint to the Attorney-General of the United States and local U.S. Attorney; and *36 expired days from the date of service of summons and complaint to the Defendant .”) [emphasis in original].
A defendant must typically file an Answer, or some other responsive pleading, within twenty (20) days of being served with the Summons and Complaint. See, Rule 12(a)(1)(A), Federal Rules of Civil Procedure. However, where, as here, “[t]he United States, a United States agency, or a United States officer or employee [is] sued only in an official capacity,” no Answer is required until sixty (60) days after service on the United States Attorney. Rule 12(a)(2), Federal Rules of Civil Procedure.
On January 10, 2008, an Affidavit of Service was filed, which disclosed that the United States Attorney was served on December 21, 2007. See, Docket No. 1J Accordingly, the Defendant’s Answer was initially due by no later than February 19, 2008. However, on February 12, 2008, counsel for the Defendant filed a Motion for an Extension of Time to file an Answer, until February 26, 2008, see, Docket No. 21, which we granted by Order dated February 13, 2008. See, Docket No. 2J Thereafter, on February 26, 2008, the Defendant duly filed a Motion to Dismiss the Plaintiffs Complaint, based upon the assertion that the Plaintiff had failed to exhaust his administrative remedies. See, Defendant’s Motion to Dismiss, Docket No. 29.
We acknowledge that the Plaintiff has asserted that there are no genuine issues of material fact, and therefore, that he is entitled to Judgment as a matter of law. See, Plaintiff’s Motion for Summary Judgment, supra at p. 1. However, the Plaintiff made that assertion, based upon
