Abstract
Commercial disputes have a way of resolving themselves that legal scholarship rarely celebrates: quietly, bilaterally, and entirely outside the structured machinery of Alternative Dispute Resolution. This chapter examines that phenomenon, specifically the settlement of commercial disputes through direct negotiation conducted without resort to any institutional ADR process. Despite being the most prevalent mode of resolution in commercial practice, out-of-ADR settlement has attracted considerably less scholarly attention than mediation, arbitration or conciliation. Drawing on comparative jurisprudence from India, England and Wales, and the United States, this chapter situates out-of-ADR settlements within the broader dispute resolution landscape and traces the contract-law, evidentiary and procedural foundations on which they rest. It examines the without prejudice rule and the Calderbank mechanism as the twin pillars supporting candidly negotiated commercial resolutions. The chapter also draws on instructive corporate disputes, including the Twitter-Musk litigation, the Cairn Energy and Vodafone retrospective tax controversies with India, the Disney-Johansson dispute over the Black Widow streaming release, and the Apple-Samsung global patent settlement, to demonstrate how sophisticated commercial actors treat direct negotiation not as a last resort but as a preferred first response once a dispute has crystallised. The chapter concludes by identifying the principal risks of the practice and proposing a calibrated framework to address them.

INTRODUCTION
The conventional account of commercial dispute resolution draws a clean line between two worlds: adversarial litigation on one side, and Alternative Dispute Resolution on the other. That neat picture leaves out something that practitioners encounter every day. A substantial proportion of commercial disputes are resolved in neither world; they settle through direct, private negotiation between the parties or their lawyers, conducted entirely outside any formal ADR process. No mediator sits in the room. No arbitral institution is engaged. This chapter calls such resolutions out-of-ADR settlements, and argues that the category deserves considerably more doctrinal attention than it has received.
The distinction is not merely taxonomic. A settlement reached through court-annexed mediation in India may be recorded as a decree of court under section 89 of the Code of Civil Procedure 1908, carrying meaningful enforcement advantages. A privately negotiated settlement, however carefully worded and however firmly intended to be final, derives its force solely from contract law. That difference in enforcement pathway has real practical consequences that practitioners and scholars alike have been slow to examine.
CONCEPTUALISING OUT-OF-ADR SETTLEMENTS
ADR is best understood as a genus rather than a single process, encompassing arbitration, mediation, conciliation and early neutral evaluation. What all of these have in common is the presence of a third party, someone who structures, facilitates or determines the outcome from a position of neutrality external to the dispute. Out-of-ADR settlement shares none of these features. It is negotiation in its purest form: an exchange of proposals and concessions between the disputing parties or their representatives, without any neutral to guide or evaluate.
Two doctrines do the most practical work in shaping how out-of-ADR negotiations are conducted. The first is the without prejudice rule. The House of Lords confirmed in Rush & Tompkins Ltd v. Greater London Council that the rule reflects a clear public policy of encouraging settlement, protecting communications genuinely aimed at compromise from being adduced against the party who made them. The second is the Calderbank mechanism, which allows a party to make an offer that will influence costs if the other side unreasonably refuses it and then fails to better it at trial. Courts have also enforced multi-tiered negotiation clauses requiring good-faith talks before formal ADR can be invoked, as in Cable & Wireless plc v. IBM United Kingdom Ltd.
III. DOCTRINAL AND STATUTORY FOUNDATIONS
The binding force of an out-of-ADR settlement rests on ordinary contract law. Where parties agree, supported by consideration, to settle their dispute, a settlement contract is formed. The doctrine of accord and satisfaction explains the mechanism: the accord is the agreement to accept a substituted performance; the satisfaction is its actual delivery. The original cause of action is extinguished, and the parties’ rights are defined entirely by the settlement’s terms.
The Indian and English frameworks are broadly consistent, though they differ in procedural texture. In India, Order XXIII Rule 3 of the Code of Civil Procedure 1908 permits a court to record and pass a decree in terms of any lawful compromise, whether it emerged from court-annexed ADR or from purely private negotiation. The Supreme Court in Afcons Infrastructure Ltd v. Cherian Varkey Construction Co (P) Ltd confirmed that legal recognition turns on lawfulness and proper recording, not on the process that produced the agreement. In England, a Tomlin order or consent order gives similar effect; no particular ADR process is required before a settlement can be recorded.
Two judicial developments have raised the profile of formal ADR without displacing private settlement. In Halsey v. Milton Keynes General NHS Trust, the Court of Appeal held that unreasonable refusal to mediate could attract costs sanctions. In Churchill v. Merthyr Tydfil County Borough Council, the Court went further, confirming that courts hold the inherent power to order parties into non-court-based dispute resolution in appropriate cases. Yet the most structurally significant gap for present purposes lies elsewhere: the Singapore Convention on Mediation, which entered into force in 2020 and provides streamlined cross-border enforcement for mediated settlements, expressly excludes settlements reached without mediation from its scope. Parties who settle privately must enforce through ordinary contract litigation in each relevant jurisdiction, a meaningful practical disadvantage that is too often overlooked.
CORPORATE PRACTICE: ILLUSTRATIVE DISPUTES
Four recent disputes illustrate how consistently sophisticated parties, with full access to formal ADR, have chosen direct negotiation instead.
In 2022, Twitter, Inc sued Elon Musk in the Delaware Court of Chancery for specific performance after Musk sought to exit his commitment to acquire the company for approximately forty-four billion US dollars. No mediation or arbitration clause was invoked. With the trial weeks away, the parties negotiated directly; Musk agreed to complete the acquisition at the original price, and the proceedings were dismissed. One of the most closely watched M&A disputes in recent memory resolved entirely through bilateral negotiation, with no mediator and no institutional process; the approaching trial date functioned as pressure, not as a resolution mechanism.
The Cairn Energy and Vodafone retrospective tax disputes with India illustrate the practice at the complex end of the spectrum, where treaty arbitration and out-of-ADR settlement intersected. Cairn obtained a favourable Permanent Court of Arbitration award in December 2020. Rather than pursuing enforcement against Indian sovereign assets, Cairn participated in a settlement framework created by the Taxation Laws (Amendment) Act 2021, withdrawing all claims in exchange for India withdrawing the retrospective tax demands. The resolution was not a further arbitral round but a consent-based negotiated settlement, demonstrating that the practice operates even at the intersection of commercial and public international law.
When Scarlett Johansson sued The Walt Disney Company in July 2021 over the simultaneous theatrical and streaming release of Black Widow, alleging breach of her contractual entitlement to theatrical revenue, the case settled within weeks through a confidential negotiated agreement, with no apparent mediation. Both parties had a strong interest in preserving a working relationship, and bilateral negotiation gave them a space to do so without the formality that even a mediation process would have imposed.
Finally, the Apple-Samsung patent dispute, which began in 2011 and sprawled across six jurisdictions over seven years at extraordinary expense, concluded in June 2018 through a direct commercial settlement with terms kept entirely confidential. Earlier court-ordered settlement conferences had produced nothing. What eventually closed the dispute was private bilateral negotiation, confirming that even the most sprawling multi-jurisdictional litigation can ultimately yield to the simplest of resolution mechanisms.
COMPARATIVE ADVANTAGES OVER FORMAL ADR
The persistence of out-of-ADR settlement despite the availability of formal ADR reflects genuine advantages that are worth naming. Cost and speed come first. Institutional arbitration has attracted sustained criticism for replicating the delay and expense of litigation it was designed to replace. The cases above tell a different story: bilateral negotiation settled the Disney-Johansson dispute in weeks and the Twitter-Musk dispute in months. Ongoing proceedings, by contrast, consume management attention, disrupt commercial relationships and generate reputational uncertainty in ways that serve neither party.
The second advantage is control. A tribunal applies law and is limited to legal remedies; it cannot order the parties into a revised commercial arrangement or a confidential acknowledgment. Direct negotiation allows exactly those kinds of outcomes. The third advantage is confidentiality. In England, arbitral confidentiality is implied rather than guaranteed, is subject to recognised exceptions, and is inevitably compromised once awards are taken to national courts for enforcement. A privately negotiated settlement with an express non-disclosure clause comes closer to complete discretion than any formal ADR process can offer.
RISKS AND DOCTRINAL CONCERNS
These advantages come with real risks. The most serious is the absence of any structural protection against a settlement reached under conditions of material inequality. A mediator brings awareness of power dynamics and practical tools to manage them: separate caucusing, controlled information flow, reality-testing. Direct negotiation offers none of this. The doctrine of economic duress provides only a thin corrective in law, demanding proof of illegitimate pressure, causally linked to the settlement, beyond the ordinary commercial hard bargaining that negotiations always involve. Courts have set that bar deliberately high, which means that settlements reached under significant commercial pressure are rarely unpicked, even when they should be.
Two further concerns deserve acknowledgment. The without prejudice rule, valuable as it is, is not absolute. In Unilever plc v. Procter & Gamble Co, the Court of Appeal recognised exceptions, including that without prejudice communications may be admitted where it is necessary to determine whether a concluded settlement was actually reached or to expose a legal wrong inducing it. Parties who negotiate informally, without the record that a mediation process provides, are more exposed to satellite litigation about these limits. Related to this is the risk of imprecise settlement terms. In Newbury v. Sun Microsystems, an exchange of solicitors’ letters was held to constitute a binding settlement notwithstanding the parties’ failure to formalise it. The litigation generated by disputes over whether and on what terms a settlement was concluded is a real, if often invisible, cost of the informality that makes out-of-ADR settlement attractive in the first place.
VII. TOWARDS A CALIBRATED FRAMEWORK
Compelling parties to pass through formal ADR before settling privately would be both unworkable and counterproductive. What is needed is more targeted. At the level of professional practice, the single most valuable reform is also the most straightforward: counsel should draft out-of-ADR settlement agreements with the rigour given to any significant commercial contract, with clear recitals, unambiguous operative terms and express confidentiality provisions. No regulatory change is required for this; it is a call for better lawyering.
Where cross-border enforcement matters, practitioners should consider routing a substantially agreed settlement through a brief formal mediation, even a single session, to bring the agreement within the Singapore Convention’s enforcement machinery. At the legislative level, extending statutory confidentiality protection to settlement negotiations more broadly, while preserving existing exceptions, would give commercial parties the certainty that the without prejudice rule alone cannot fully provide. Where bargaining power is materially unequal, requiring independent legal advice before execution of the settlement provides a proportionate safeguard without the time and cost of full mediation.
VIII. CONCLUSION
Out-of-ADR settlement is not a preliminary to formal dispute resolution, nor an informal fallback; measured by how disputes actually end, it is the dominant mode of commercial resolution in practice. The Twitter-Musk proceedings, the Cairn Energy and Vodafone tax controversies, the Disney-Johansson dispute and the Apple-Samsung litigation each concluded through direct bilateral negotiation, entirely outside any ADR framework. Parties with ready access to arbitration clauses, mediation programmes and institutional services chose instead to negotiate privately until they reached the terms they could both accept. The doctrinal foundations, contract formation, accord and satisfaction, the without prejudice rule and the Calderbank mechanism, are well established even if not designed specifically for this purpose. The risks, from bargaining inequality to privilege limits to cross-border enforcement gaps, are real but tractable through better drafting discipline, strategic use of brief mediation to access the Singapore Convention, and targeted legislative reform. For a volume on arbitration and mediation in commercial matters, taking out-of-ADR settlement seriously as a subject in its own right is long overdue.
