ORDER AND JUDGMENT *

This appeal involves two issues: (1) did the district court err in finding Heindel Siribuor, a pro se attorney, to have knowingly and voluntarily entered into a binding settlement agreement with defendants regarding his Title VII harassment and racial discrimination claims; and (2) did the district court err in imposing attorney’s fees as a sanction for Mr. Heindel’s attempt to renege on the settlement contract. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm in part and dismiss in part for lack of jurisdiction.

With regard to the first issue on appeal, we easily conclude Mr. Heindel entered into a binding settlement agreement, and affirm for substantially the same reasons relied on by the magistrate judge and the district judge in their extremely thorough orders. See R., Doc. 45 at 1-4, 6-9; Doc. 54 at 1-3, 6-8. Simply put, Heindel knowingly and voluntarily authorized the settlement agreement in email messages he sent to defense counsel on February 27, 2012. Id., Doc. 45 at 3-4 (¶¶ 3-10). Heindel claims the settlement agreement was un *812 enforceable because the terms of a release had not been negotiated, there was inadequate consideration, and defendants breached a confidentiality requirement, but the magistrate and the district judges correctly rejected his arguments for lack of merit.

With regard to the second issue, we lack jurisdiction to review the award of attorney’s fees because the district court has yet to enter an order reducing the award to a sum certain. See Am. Soda, LLP v. U.S. Filter Wastewater Group, Inc., 428 F.3d 921, 924 (10th Cir. 2005) (“An award of attorneys’ fees is not final and appeal-able within the meaning of 28 U.S.C. § 1291 until it is reduced to a sum certain.”). “This, however, does not preclude our review of the district court’s ... order [regarding the settlement agreement].” Id. at 925. As we have explained, “[i]t is well settled that a decision on the merits is a final decision for purposes of § 1291 whether or not there remains for adjudication a request for attorney’s fees attributable to the case.” Id. (internal quotation marks omitted).

The judgment of the district court enforcing the parties’ settlement agreement is affirmed. Heindel’s appeal of the award of attorney’s fees is dismissed for lack of jurisdiction. Heindel’s motion to file his appendix under seal is denied because the documents included in it are already part of the public record in the district court.
