Case Explained: MARK D. WEISSMAN WEATHERLY AVIATION COMPANY INC a Delaware Corporation v. MICHAEL CHEOKAS

Court: United States Court of Appeals for the Eleventh Circuit Filed: 2026-06-18 Docket: 1:17-cv-00220-WLS The Eleventh Circuit affirmed the district court’s enforcement of a settlement agreement reached during mediation, its denial of a motion to enforce confidentiality provisions regarding that settlement, its imposition of sanctions against the appellant’s counsel under 28 U.S.C. § 1927, and its denial of leave to amend the complaint. The court applied de novo review to the contract interpretation and abuse of discretion review to the enforcement of the settlement, sanctions, and amendment denial. Regarding the confidentiality dispute, the court held that Georgia law requires giving effect to the plain meaning of contractual language. The Mediation Agreement explicitly distinguished between confidential “communications… in the mediation” and admissible “written agreement made and executed… as a result of the mediation.” The email exchange memorializing the settlement terms fell within the latter category, rendering it admissible despite the general confidentiality clause. Additionally, the court found that the mediator’s testimony regarding whether an agreement was reached was permissible under the Georgia Uniform Mediation Act (O.C.G.A. § 9-17-6(b)(1)), as it confirmed the termination of mediation and the existence of a settlement without revealing confidential bargaining positions. On the enforceability of the settlement, the court applied Georgia’s objective standard for mutual assent, finding that the email exchange constituted an offer, counteroffer, and unequivocal acceptance of essential terms. The subsequent disagreement regarding sanctions did not negate the prior meeting of the minds on the core agreement. Regarding sanctions, the court found no abuse of discretion or due process violation under § 1927. The record supported a finding that counsel acted in bad faith by unreasonably and vexatiously multiplying proceedings through repeated filings advancing unsupported positions after the settlement was reached, which necessitated additional hearings and delayed resolution. Finally, the court upheld the denial of leave to amend as an abuse of discretion was not shown, noting the motions were filed with undue delay just two weeks before trial and would have caused prejudice by requiring a reopening of discovery and revisiting dispositive motions. The practical consequence is that the settlement agreement remains binding, the case is effectively resolved in favor of the appellee, the sanctions against counsel stand, and the appellant’s attempt to alter the pleadings or exclude settlement evidence was unsuccessful.
