Email-Assented Mediated Settlements Are Enforceable and Admissible Despite Mediation Confidentiality; Mediators May Testify to Settlement Existence Under Georgia Law

1) Precedents Cited

A. Appellate jurisdiction and “functional” finality

• Martinez v. Carnival Corp., 744 F.3d 1240 (11th Cir. 2014) and United States v. Alabama, 828 F.2d 1532 (11th Cir. 1987): The court used these to hold that even without a formal dismissal, an order can be “final” if it resolves all issues and leaves only execution of judgment. The opinion emphasized the “specificity, detail, and comprehensiveness” of the district court’s order as the hallmark of finality.
• Lussier v. Dugger, 904 F.2d 661 (11th Cir. 1990): Cited to note that United States v. Alabama was superseded on other grounds, but its finality reasoning remains useful.
• Cunningham v. Hamilton Cnty., 527 U.S. 198 (1999) and Budinich v. Becton Dickinson & Co., 486 U.S. 196 (1988): Used for “merger” principles—prior rulings (including sanctions) merge into the final judgment for appellate review.

B. Contract interpretation and settlement formation under Georgia law

• Tims v. LGE Cmty. Credit Union, 935 F.3d 1228 (11th Cir. 2019) and Atlanta Dev. Auth. v. Clark Atlanta Univ., Inc., 784 S.E.2d 353 (Ga. 2016): These anchored the court’s “plain meaning first” approach: if a contract’s language is unambiguous, courts enforce it as written. The panel applied that principle to the Mediation Agreement’s confidentiality clause and its express exception for “written agreements.”
• Bazemore v. Jefferson Cap. Sys., LLC, 827 F.3d 1325 (11th Cir. 2016): Cited for Georgia’s essential contract elements (via O.C.G.A. § 13-3-1), including mutual assent and definite subject matter.
• Cox Broad. Corp. v. Nat'l Collegiate Athletic Ass'n, 297 S.E.2d 733 (Ga. 1982): Provided the objective standard for “meeting of the minds”—assent is judged by reasonable understanding of words/conduct, not later regret.
• Maddox v. Life & Cas. Ins. Co. of Tenn., 53 S.E.2d 235 (Ga. Ct. App. 1949): Supported the offer/counteroffer/acceptance framing: a counteroffer must be accepted to form a binding agreement—here it was, explicitly.
• Newman v. Newman, 732 S.E.2d 77 (Ga. 2012): Used to reject the idea that later disagreement or later-recognized ambiguity destroys earlier assent to essential terms.
• Citizens & S. Nat'l Bank v. Williams, 249 S.E.2d 289 (Ga. Ct. App. 1978): Cited to explain courts may consider surrounding communications to assess formation questions (including whether a valid contract was formed).

C. Email settlements as enforceable written agreements

• Brumbelow v. N. Propane Gas Co., 308 S.E.2d 544 (Ga. 1983): A cornerstone for settlement enforcement: attorney-prepared letters/documents memorializing settlement terms can suffice. The panel used this to classify the June 12 emails as a sufficient memorialization.
• Johnson v. DeKalb Cnty., 726 S.E.2d 102 (Ga. Ct. App. 2012): Reinforced that emails between lawyers can memorialize essential settlement terms.
• Cumberland Contractors, Inc. v. State Bank & Tr. Co., 755 S.E.2d 511 (Ga. Ct. App. 2014): Supported enforcement even where a settlement document is unsigned, so long as essential terms were agreed via email.
• State v. Federal Defender Program, Inc., 882 S.E.2d 257 (Ga. 2022): Cited for the modern proposition that emails bearing counsel’s names and definite terms may satisfy writing/signature concepts (including statute of frauds contexts), strengthening the idea that email assent can “execute” an agreement.
• Miller v. Miller, 846 S.E.2d 429 (Ga. Ct. App. 2020): Confirmed that a settlement may be binding absent a formal signed document when authorized counsel exchange written assent.

D. Mediation confidentiality and mediator testimony

• O.C.G.A. § 9-17-6(b)(1): Though a statute, it functioned like a controlling “precedent” in the court’s analysis: a mediator may disclose whether mediation occurred/terminated, whether a settlement was reached, and attendance. The panel relied on this to uphold the mediator’s limited testimony about settlement existence.
• Dear v. Q Club Hotel, LLC, 933 F.3d 1286 (11th Cir. 2019): Cited in the standards section (contract interpretation de novo) and implicitly supports rigorous review of contract meaning—important where confidentiality is invoked to block settlement enforcement.

E. Sanctions under 28 U.S.C. § 1927 (standards, due process, and causation)

• Norelus v. Denny's Inc., 628 F.3d 1270 (11th Cir. 2010): Provided the abuse-of-discretion framework for reviewing § 1927 sanctions.
• Amlong & Amlong, P.A. v. Denny's, Inc., 500 F.3d 1230 (11th Cir. 2007): Central authority for § 1927: sanctions target objectively bad-faith or reckless conduct, not mere negligence; also cited for the entitlement to a hearing.
• Peterson v. BMI Refractories, 124 F.3d 1386 (11th Cir. 1997) and Peer v. Lewis, 606 F.3d 1306 (11th Cir. 2010): Used for the three-part test: (1) unreasonable/vexatious conduct, (2) multiplying proceedings, and (3) a causal financial nexus to excess costs.
• In re Mroz, 65 F.3d 1567 (11th Cir. 1995): The due process touchstone: adequate notice and an opportunity to be heard; notice can come from the court or opposing party.
• Malautea v. Suzuki Motor Co., 987 F.2d 1536 (11th Cir. 1993): Illustrated that obstructive conduct that forces extra proceedings and court intervention can evidence bad faith supporting sanctions.
• Schwartz v. Millon Air, Inc., 341 F.3d 1220 (11th Cir. 2003): Reinforced that “multiplying proceedings” covers unreasonable conduct causing unnecessary litigation steps.
• Serra Chevrolet, Inc. v. Gen. Motors Corp., 446 F.3d 1137 (11th Cir. 2006): Cited for de novo review of due-process challenges to sanctions—underscoring the importance of procedural fairness even when conduct is blameworthy.
• J.C. Penney Corp. v. Oxford Mall, LLC, 100 F.4th 1340 (11th Cir. 2024), Skanska USA Civ. Se. Inc. v. Bagelheads, Inc., 75 F.4th 1290 (11th Cir. 2023), and OHI Asset (VA) Martinsville SNF, LLC v. Wagner (In re Wagner), 115 F.4th 1296 (11th Cir. 2024): Provided the clear-error framework for reviewing factual findings like “bad faith.”

F. Leave to amend (timing, prejudice, waiver of non-forum law)

• Forbus v. Sears Roebuck & Co., 30 F.3d 1402 (11th Cir. 1994): Used for the abuse-of-discretion standard on denial of leave to amend.
• Foman v. Davis, 371 U.S. 178 (1962): The canonical factors: undue delay, bad faith, repeated failure to cure, futility, and undue prejudice justify denial—here, undue delay and prejudice dominated.
• Burger King Corp. v. Weaver, 169 F.3d 1310 (11th Cir. 1999): Emphasized leave should be “freely” given, but district courts may deny for substantial reasons consistent with Foman.
• Sun Life Assurance Co. of Can. v. Imperial Premium Fin., LLC, 904 F.3d 1197 (11th Cir. 2018): Important choice-of-law principle: a party may waive reliance on non-forum law if it fails to timely provide the sources on which it seeks to rely. This supported skepticism toward a late switch to California/Illinois law close to trial.
• Gonzalez v. Governor of Ga., 978 F.3d 1266 (11th Cir. 2020), United States v. Beaufils, 160 F.4th 1147 (11th Cir. 2025), Rasbury v. IRS (In re Rasbury), 24 F.3d 159 (11th Cir. 1994), and United States v. Kelly, 888 F.2d 732 (11th Cir. 1989): These collectively framed what counts as an abuse of discretion and the “range of permissible choices” available to trial courts managing litigation timing and fairness.

G. Mistake and rescission (raised as a doctrinal aside)

• Patterson v. CitiMortgage, Inc., 820 F.3d 1273 (11th Cir. 2016), Werner v. Rawson, 15 S.E. 813 (Ga. 1892), and O.C.G.A. § 23-2-31: The court referenced unilateral mistake doctrine—rescission may be possible in narrow circumstances—but it did not find facts here supporting undoing the settlement.

2) Legal Reasoning

A. Reading mediation confidentiality as written—confidentiality is not an anti-enforcement weapon

The opinion’s interpretive move is straightforward and consequential: it treats mediation confidentiality as a contractual allocation of what remains private, not as a mechanism that allows one party to repudiate a deal and then suppress the very writings that prove agreement. Invoking Tims v. LGE Cmty. Credit Union and Atlanta Dev. Auth. v. Clark Atlanta Univ., Inc., the panel enforced the clause’s plain meaning.

The Mediation Agreement protected “all communications of the parties in the mediation,” but expressly allowed use of “any written agreement made and executed by the parties as a result of the mediation.” The court characterized the June 12 emails as exactly that: a written memorialization, sent within hours, capturing the negotiated terms and completing the assent (“We agree to these changes.”).

B. Mediator testimony: limited disclosure permitted under the Georgia Uniform Mediation Act

Even if parties contract for strict confidentiality, mediator disclosure is also governed by applicable law. The court held the mediator’s testimony fit within O.C.G.A. § 9-17-6(b)(1), which allows disclosure of whether mediation occurred/terminated and whether a settlement was reached. The mediator did not relay bargaining positions or private caucus content; he testified to settlement existence and memorialization. The panel treated that distinction—terms/content versus existence/termination—as the dividing line.

C. Settlement formation: objective assent, not post hoc “no meeting of the minds”

Applying Georgia contract principles via Bazemore v. Jefferson Cap. Sys., LLC and Cox Broad. Corp. v. Nat'l Collegiate Athletic Ass'n, the court asked whether a reasonable person would view the communications as mutual assent to essential terms. The emails satisfied classic formation steps:

• Offer: dismissal; $34,250; timing; mutual releases.
• Counteroffer: dismissal with prejudice; 14 business days; carve-out for sanctions/fee petitions.
• Acceptance: “We agree to these changes.”

The panel supported this with Maddox v. Life & Cas. Ins. Co. of Tenn. and strengthened enforceability with the email-settlement line of cases: Brumbelow v. N. Propane Gas Co., Johnson v. DeKalb Cnty., and Cumberland Contractors, Inc. v. State Bank & Tr. Co., plus modern email “writing/signature” analysis from State v. Federal Defender Program, Inc. and authority-to-bind reasoning from Miller v. Miller.

Weissman’s later dispute about sanctions did not undo the deal. Relying on Newman v. Newman, the court treated later disagreement or clarification needs as insufficient to negate objective assent to essential settlement terms.

D. § 1927 sanctions: repudiation-driven motion practice can be “vexatious” when it needlessly prolongs litigation

The court applied the Eleventh Circuit’s structured § 1927 test from Peterson v. BMI Refractories and Peer v. Lewis, with the bad-faith gloss from Amlong & Amlong, P.A. v. Denny's, Inc.. Key points in the reasoning:

• Due process: Under In re Mroz, notice may come from the opposing party’s motion. The sanctions request was explicit in Cheokas’s motion. A hearing occurred; counsel had an opportunity to respond.
• Bad faith (objective): The court distinguished an initial position from continued pursuit after the position was untenable on the record. It found counsel’s persistent litigation posture needlessly obstructed resolution.
• Multiplication of proceedings: By forcing additional motion practice and an evidentiary hearing about a settlement the court deemed plainly established, counsel caused “excess proceedings” as contemplated by Schwartz v. Millon Air, Inc. and Peer v. Lewis.

E. Late amendments: litigation management and fairness to the opposing party

On the eve of trial—after years of litigation—Weissman sought to shift governing law (to California/Illinois) and add punitive damages. The court treated the timing as dispositive: under Foman v. Davis and Burger King Corp. v. Weaver, undue delay and prejudice justify denial. The citation to Sun Life Assurance Co. of Can. v. Imperial Premium Fin., LLC underscored that a late pivot to non-forum law can be deemed waived if not timely presented.

F. A notable procedural aside: enforcement framed with a summary-judgment-like lens

In footnote discussion, the panel noted the district court used a summary-judgment-style approach (citing Ballard v. Williams and Cohen v. DeKalb Cnty. Sch. Dist.) to evaluate settlement enforceability, while also taking evidence at a hearing. The Eleventh Circuit did not resolve whether that was the “correct vehicle” because neither party challenged it and the dispositive facts were written and undisputed. Practically, this signals that where the record is documentary and clear, appellate review will focus on contract formation rather than procedural labels.

3) Impact

• Mediation confidentiality is not absolute: Clauses that protect “communications in mediation” will not prevent courts from considering a “written agreement” resulting from mediation—especially where the agreement itself includes an admissibility exception. Parties seeking true evidentiary exclusion must draft with precision, and even then must contend with statutory disclosure rules (here, O.C.G.A. § 9-17-6(b)(1)).
• Email can “execute” a settlement: The opinion strengthens the litigation reality that settlement agreements often crystallize in counsel email exchanges. A later demand for a formal signature page will not necessarily defeat enforcement if essential terms were agreed and counsel acted with authority.
• Post-agreement repudiation can create sanctions exposure: The case illustrates how continued litigation to resist an enforceable settlement—after the record shows agreement—can be treated as vexatious multiplication of proceedings. This is especially salient where counsel declines to substantively contest evidence at an evidentiary hearing.
• Trial-cusp amendments face steep headwinds: Attempts to reframe governing law or add damages theories near trial will likely be denied absent compelling justification, given prejudice, scheduling, and waiver doctrines.
• Practical guidance for litigants: If parties want a settlement to be non-binding until a formal document is signed, they must say so explicitly in the email exchange and in the mediation term sheet, and should avoid language of unequivocal acceptance.

Because the opinion is designated “NOT FOR PUBLICATION,” it is not binding precedent, but it is a detailed application of existing Georgia and Eleventh Circuit doctrine that will be persuasive in analogous settlement-enforcement disputes.
