Competition & Regulation

Our Competition & Regulation Department combines technical expertise with a practical problem-solving approach to legal issues. We are consistently ranked in the top tier of Irish advisers for Competition & Regulation work by leading directories including Chambers Europe, Global Competition Review and the Legal 500 EMEA.

Areas of expertise include:

We represent clients regarding competition investigations before the Irish Competition and Consumer Protection Commission (formerly the Competition Authority) and the European Commission. We have wide experience of practising competition law in the UK, Brussels and Luxembourg, having represented clients before the UK's Competition and Markets Authority (Formerly the Office of Fair Trading), the European Commission, the Court of Justice of the EU and the General Court.  We also focus on cartel investigations.

Our expertise in merger control notifications under both Irish and EU merger control rules is widely acknowledged. We frequently co-ordinate multi-jurisdictional merger control filings.

We advise Irish and international clients across a range of regulated sectors, including telecoms, broadcasting, energy and transport. We also advise on certain white-collar crime issues including anti-money laundering.

Our experience in both EU and Irish public procurement law has proven invaluable to contracting authorities (including utility companies) in running projects in compliance with applicable EU and Irish rules.

We are experienced in all areas of EU law, including free movement issues, rights of establishment and customs and trade law.  We also advise on both the EU and Irish export licensing regimes for dual-use and military goods. 

On contentious issues, we work with our Litigation & Dispute Resolution Department to achieve a positive outcome for clients.

Our experience includes advising:
