Dr Karl Mackie CBE, the barrister, academic and business psychologist who did more than almost anyone to establish commercial mediation in England and Wales, has died at the age of 79. The Centre for Effective Dispute Resolution (CEDR), the organisation he co-founded, confirmed his death.

Mackie set up CEDR in 1990 with Eileen Carroll KC (Hon) at a point when mediation barely registered as a serious option in the English legal system. Litigation was the default, alternative dispute resolution was treated as a curiosity, and the pair began with two members of staff working from a borrowed room at Carroll's law firm. Three decades on, CEDR is one of the best known dispute resolution bodies in the world, and mediation is a routine step in commercial disputes rather than an exotic alternative to court.

From a borrowed room to an international institution

CEDR managing director John Munton said Mackie was 'one of those rare people who helped define an entire profession', crediting his 'vision, courage and determination' with turning mediation from an unfamiliar concept into a mainstream way of resolving conflict. Munton noted that Mackie and Carroll were championing the idea across the profession from the earliest days of the 1990s, and that Mackie led the organisation through the years in which it grew into an internationally recognised voice for mediation.

Susanne Schuler, CEDR's global director of development, said his reach extended well beyond the UK. 'Karl's influence reached every corner of the international mediation community,' she said. 'Wherever CEDR works today, we continue to encounter mediators, judges, lawyers and policymakers whose careers were shaped by his teaching, his writing or his personal encouragement.' He believed, she added, that mediation could improve not only legal systems but relationships, organisations and society itself — a commitment to excellence 'matched by his kindness'.

A career built across disciplines

Before CEDR, Mackie worked as an academic, a business psychologist and a barrister, an unusual combination that shaped his approach to conflict as much a human problem as a legal one. His appointments included vice-chair of the Civil Mediation Council and chief adjudicator of Ofsted's Independent Complaints Adjudication Service, alongside advisory roles with universities and international organisations. The Times gave him the label that stuck: 'Mr Mediation'.

Why it matters for law firm leaders

For firms running commercial disputes practices, the infrastructure Mackie helped create is now part of the operating model. Mediation training, accreditation routes, panel appointments and court expectations around settlement all trace back in some measure to the institutions built in the 1990s. Successive civil justice reforms, and more recent moves towards compulsory dispute resolution steps, rest on the assumption that a credible mediation profession exists — an assumption that was far from safe when CEDR opened its doors.

  • Commercial mediation moved from novelty to standard practice within a single generation
  • CEDR's founding in 1990 created the training and accreditation backbone still used today
  • Court and government policy increasingly assume settlement routes exist before trial

Tributes from CEDR were extended to Carroll, Mackie's family and those close to him.
