About CaseTag

A specialised legal research platform built by EU competition law experts, for legal professionals who need verified, structured case law analysis.

Why CaseTag exists

EU competition law and digital regulation are evolving faster than ever. The Digital Markets Act has created an entirely new enforcement landscape alongside the established body of Articles 101 and 102 TFEU case law. Keeping track of how legal principles develop across courts, institutions, and regulatory frameworks is a growing challenge for practitioners, academics, and in-house teams alike.

CaseTag was created to solve a specific problem: making it easy to find, understand, and connect EU case law across the areas that matter most for competition and digital regulation. Not through AI-generated summaries that may hallucinate or miss nuance, but through expert-curated analysis you can rely on.

Who's behind it

CaseTag is built and maintained by Daniel Geradin, who works at the intersection of EU competition law, digital regulation, and legal research — affiliated with both Leiden University and Geradin Partners.

Every case in the database is selected, structured, and analysed based on deep expertise in EU competition enforcement, merger control, and the DMA regulatory framework. The Master Files are written by specialists, not generated by algorithms.

Expert curation, not automation

While AI tools can generate case summaries, they cannot guarantee accuracy, verify doctrinal connections, or make the editorial judgments that legal research demands. CaseTag's value lies in the quality of its curation — every Master File reflects a specialist's analysis of what a case stands for and how it fits into the broader legal landscape.

What CaseTag covers

The database covers two core areas of EU law:

EU Competition Law
Articles 101 and 102 TFEU, merger control under the EU Merger Regulation, and state aid enforcement.
EU Tech Regulation
Starting with the Digital Markets Act (DMA) — gatekeeper obligations, compliance decisions, and the intersection with competition enforcement. Further regulatory areas will be added as enforcement develops.

Open beta

CaseTag is currently in open beta. Every feature — search, Master Files, doctrinal mapping, and case correlations — is freely accessible while we build out the database. We are adding new cases regularly, with priority given to landmark decisions and cases that establish or refine significant legal principles.

If you have suggestions for cases that should be included, or feedback on the platform, we would love to hear from you at support@casetag.eu.
