Definitions and coding guidance for the variables used across the UK-CLAD datasets.
Limitations: CAT proceedings only (High Court claims are out of scope); most cases settle confidentially, so the data captures litigated outcomes rather than all disputes. See the codebook for detail.

Analysing Judicial Case Data for Access to Justice: A Methodological Framework
This article presents the first comprehensive analysis of cases adjudicated before the Competition Appeal Tribunal (CAT) between 2004 and 2025. Employing a structured coding framework to classify party types, case outcomes, durations, and other salient variables, it investigates the obstacles faced by consumers and small and medium-sized enterprises (SMEs) in accessing justice in UK competition law litigation. The findings demonstrate that structural and economic barriers, rather than doctrinal complexity, constitute the principal impediments to redress. The article details the study's methodological design and reflects critically on its strengths and limitations.
