In No. 04-1212, appellant Brian Dasey appeals from the district court’s denial of his motions under Fed.R.Civ.P. 60(b), for reconsideration, and for sanctions. In No. 04-1605, he appeals from the denial of a second motion for reconsideration and a motion for leave to supplement his filings.

After careful review of the record and the parties’ arguments, we affirm the judgments below, concluding that the district court did not abuse its discretion in denying Dasey’s motions. We agree substantially with the reasoning in the district court’s Memorandum of Decision dated January 29, 2004, and its March 2, 2004 endorsed order denying reconsideration. In addition, as appellees contend, Dasey may not use a Rule 60(b) motion to relitigate issues already decided by this court, Dasey v. Anderson, 304 F.3d 148, 151 (1st Cir. 2002), or to raise issues that might have been, but were not, asserted in prior court proceedings. 12 Moore’s Fed. Prac. § 60.48[3][c], at 60-174.1 (3d ed. 2003) (confirming that a party’s “[f]ailure to take advantage of an opportunity to litigate an issue precludes use of that issue to secure” Rule 60(b)(6) relief). Finally, Dasey’s motions failed to establish the alleged “fraud on the court.”

The judgments in the above appeals are affirmed. 1st Cir. Loe. R. 27(c).
