The research used information provided by online legal information provider Lawtel. The statistics, which relate to all civil litigation, save for immigration cases, were obtained for 22 of the UK's leading chambers. An appearance is recorded for a judgment handed down during the last judicial year, which ran from October 1999-July 2000. The outcomes of cross appeals, or short interlocutory applications, have not been recorded. Some barristers have since moved sets, but appearances are credited to the chambers where they held tenancy during the relevant period.
