Competition and Regulation

Our Competition and Regulation group is ranked as an ‘Elite’ practice by leading trade publication, Global Competition Review (GCR), and consistently features in the highest tier of competition advisers in the top legal directories. We are a diverse and experienced group of specialists, with many having previously worked in major international competition practices in London and Brussels.

We advise on all aspects of Irish and EU competition and regulatory law, including merger control and foreign direct investment (FDI) screening, competition enforcement and litigation, State aid, procurement, consumer law regulation,  sectoral regulation including the Digital Markets Act (DMA) regime, the EU Foreign Subsidies Regulation (FSR) regime.

We adopt a pragmatic and commercial approach which consistently delivers successful outcomes in the most complex cases.  In particular:

  • the group has led on many Phase 2 Irish merger reviews, acted on the only ever Phase 2 Irish media plurality review, and acted on FDI review processes involving the imposition of conditions;
  • has advised on all EU Commission investigations and dawn raids in Ireland in recent years and many recently completed high-profile competition investigations by the Competition and Consumer Protection Commission; and
  • advising on the most complex competition litigation matter (Trucks Litigation) currently before the Irish courts.
