Alternative dispute resolution
A range of third-party-assisted processes for settling disputes outside litigation.
Alternative dispute resolution (ADR), also known as external dispute resolution (EDR), encompasses a broad spectrum of processes and techniques that allow parties in a disagreement to settle their differences with the assistance of a neutral third party. These methods are typically employed when the disputing parties cannot reach an agreement on their own and wish to avoid formal litigation. However, ADR is increasingly integrated into the court system itself. Historically, many parties and their legal advocates resisted ADR, but it has since achieved widespread acceptance. By 2008, some courts began requiring parties to participate in certain ADR processes, such as mediation, before a case could proceed to trial—a practice known as compulsory mediation, where attendance is mandatory but a settlement is not. In England and Wales, ADR is now often termed Non Court Dispute Resolution (NCDR) to promote it as the standard method of dispute resolution. A landmark 2023 Court of Appeal judgment in *Churchill v Merthyr* confirmed that courts can order parties to engage in NCDR or stay proceedings to allow for it, overturning the previous 2004 precedent from *Halsey v. Milton Keynes General NHS Trust* that had prevented courts from compelling unwilling parties to participate. The rising popularity of ADR stems from factors such as the growing caseload of traditional courts, lower costs compared to litigation, a preference for confidentiality, and the desire for parties to have more control over who decides their dispute. Senior judiciary in some jurisdictions, including England and Wales, strongly support this trend, as have many American courts since the 1990s. The term "alternative dispute resolution" originated from Frank Sander's paper "Varieties of Dispute Processing." Traditional arbitration involved guild heads or dominant authorities, whereas modern arbitration relies on commercial vendors who are more readily available but lack the social dominance or community ties of earlier arbitrators. ADR can also be conducted online, known as online dispute resolution (ODR), which may be provided by government entities or on a global scale where domestic remedies are unavailable, such as in domain name disputes under the UDRP. In England and Wales, the Online Procedure Rule Committee, established under the Judicial Review and Courts Act 2022 and chaired by the Master o
Lore & Background
The term 'alternative dispute resolution' arose from Frank Sander's paper, 'Varieties of Dispute Processing'. Traditional arbitration involved heads of trade guilds or other dominant authorities settling disputes. The modern innovation was to have commercial vendors of arbitrators, often with little social or political dominance over the parties, making them more readily available but not involving the community of the parties. ADR can increasingly be conducted online, known as online dispute resolution (ODR), which may be provided by government entities and on a global scale, as in the case of the UDRP and domain name disputes.
Reader's Guide
Alternative dispute resolution encompasses a range of processes where a neutral third party assists disputing parties, used when agreement cannot be reached without litigation and increasingly adopted within court systems. Historically, the term originated from Frank Sander’s work on dispute processing varieties. Traditional arbitration involved guild leaders or dominant authorities, whereas modern innovation introduced commercial arbitrators with less social power over parties, offering greater availability but lacking community involvement. ADR is generally divided into four classes: negotiation, mediation, collaborative law, and arbitration, though some contexts exclude arbitration from ADR, and conciliation is sometimes included within mediation. Conflict resolution is the primary goal, with ADR considered an alternative to litigation; it can also colloquially mean dropping a dispute or avoiding violence. A systems approach has emerged, advocating for appropriate dispute resolution by directing some cases to formal grievance or courts while offering coaching, mediation, or arbitration for others. Online dispute resolution (ODR) allows ADR to be conducted digitally, often by government entities as part of litigation, and globally where domestic remedies are lacking, as with domain name disputes. In England and Wales, the Online Procedure Rule Committee, chaired by the Master of the Rolls, was established under the Judicial Review and Courts Act 2022 to govern online proceedings across civil, family, and tribunal jurisdictions.
Did You Know?
- In England and Wales, ADR remains the dominant term; while 'Non Court Dispute Resolution' (NCDR) is sometimes used, it has not replaced ADR in common usage.
Scope and Purpose of Online Dispute Resolution
ODR represents a broad technological layer applied to the existing landscape of dispute resolution. Rather than replacing negotiation, mediation, or arbitration, it channels these established processes through digital infrastructure, making them accessible to parties who may be separated by significant geographic distance. The field spans an impressive range of conflicts: from everyday consumer-to-consumer disagreements and marital separations all the way up to court proceedings and even interstate tensions. While ODR is not confined to business-to-consumer transactions, it finds its most natural home in e-commerce disputes, where the very medium that created the conflict (the internet) also provides the most logical venue for resolving it. Designers of ODR systems must balance the competing interests of individual consumers and commercial entities while embedding a thorough understanding of procedural justice into every step. Proponents argue that efficient online resolution mechanisms will be a critical driver in the continued growth of electronic commerce, removing one of the key barriers that has historically limited cross-border digital trade.
The Fourth Party: Technology as an Independent Actor
One of the most striking conceptual contributions to ODR scholarship is the designation of technology itself as a "fourth party" in the dispute process. Coined by Katsh and Rifkin, this label elevates software and computing systems from mere tools to an independent force that actively shapes how information is managed, how communications flow, and how parties interact. In a traditional three-sided model—two disputants plus a neutral—the fourth party disrupts the geometry entirely. It can organize evidence, dispatch automatic responses, filter hostile language from written exchanges, monitor compliance, schedule sessions, and even help parties articulate their underlying interests and priorities. At times it steps in to replace the neutral altogether, as in fully automated negotiation, while at other times it serves as an assistant to the third party. Katsh and Wing have noted that technological capability is advancing on an exponential curve, meaning the fourth party's influence will only deepen. Some scholars have gone so far as to predict virtual avatar judges that grow more sophisticated over time, further compressing the time and cost burden that disputants traditionally bear.
The Spectrum of Control and the Full Online Process
Dispute resolution techniques exist along a continuum, stretching from scenarios in which the parties retain complete authority over procedure to those in which a third-party neutral governs both the process and the final outcome. ODR sits within this spectrum but adds a distinctive digital dimension: when the bulk of the procedure—initial filing, appointment of a neutral, exchange of evidence, oral hearings, structured discussions, and the issuance of binding settlements—takes place online, the process qualifies as ODR. It is, in essence, a different medium for carrying out dispute resolution from start to finish while still honoring due process principles. The field was born out of a practical gap: disputes were multiplying in online spaces where traditional resolution channels proved slow, costly, or simply inaccessible. Today, the boundary between offline and online proceedings has grown increasingly porous. Some commentators restrict ODR to ADR processes assisted principally by ICT tools, while a broader school of thought encompasses online litigation and other bespoke forms of dispute resolution that rely heavily on purpose-built digital infrastructure. The most fitting characterization, many argue, is to treat ODR as an interdisciplinary field rather than a standalone discipline.
Automated Negotiation and the Blind-Bidding Model
Among the most distinctive methods within the ODR toolkit is automated negotiation, a category in which technology assumes direct control over aspects of the bargaining process. The most prevalent implementation of this approach is the so-called blind-bidding service, a structured mechanism designed to determine economic settlements in claims where liability is not challenged. Functioning much like a constrained auction, the system allows parties to submit offers while keeping some or all information about those bids concealed from the other side. A resolution is formally declared by the platform at the close of a negotiating session once all participants have accepted one or more settlement packages. Because the technology handles the negotiation directly, it can at times take the place of the third-party neutral entirely, as the ODR literature explicitly notes. The approach exemplifies how ODR can go beyond merely digitizing existing ADR procedures and instead introduce novel resolution techniques that leverage digital infrastructure to produce meaningful time savings and cost reductions for disputants.
Frequently Asked Questions
Who is Alternative dispute resolution?
ADR (also called external dispute resolution) is a collection of third-party-assisted settlement methods—such as mediation, arbitration, and conciliation—that parties use when they cannot agree on their own but want to sidestep full court litigation. The umbrella label was coined in Frank Sander's academic paper, which gave these previously separate techniques a shared identity.
Why is Alternative dispute resolution important?
ADR matters because it typically resolves conflicts faster, at lower cost, and with less adversarial heat than a full trial, often preserving the working relationship between the parties. Its rise mirrors a wider legal-culture shift toward consensual, flexible settlement over winner-takes-all courtroom battles.
What is Alternative dispute resolution's origin story?
Before Sander's paper unified the field, mediation, arbitration, and conciliation existed as loosely connected, independently named practices. Sander's contribution was to bundle them under the single phrase 'alternative dispute resolution,' giving the whole family a recognizable name and a coherent academic framework.
