Michael Madden


Michael is a partner in our Competition & Antitrust team.

With almost 20 years’ experience, he is a regulatory specialist with particular expertise in advising on Irish and EU media and telecoms regulation.

Michael advises domestic and international clients on all aspects of Irish and EU audiovisual media services law, including well known video-sharing platforms on changes brought about by the revised AVMS Directive. 

He also advises many high profile online platforms on the regulation of harmful content and online safety regimes.  This is increasingly relevant as many jurisdictions, including Ireland, seek to minimise the online availability of harmful content through regulation.

Michael also has intimate knowledge of the Irish and EU telecoms regulatory frameworks.  He advises both domestic and international clients on all aspects of telecoms regulation.  He also advises many well-known online service providers on the scope and application of the new European Electronic Communications Code which will bring many such companies within the scope of telecoms regulation for the first time.

He advises clients on competition law matters, in particular in relation to media merger control and State aid.

Prior to joining Mason Hayes & Curran LLP, Michael worked with the telecoms regulator, ComReg.  This allows him to bring a unique mix of experience and expertise to bear in advising clients on regulatory matters and in ensuring a practical and effective approach to engagement with national and EU regulators.

Michael has taught at Irish and international universities and contributes to a wide variety of publications on regulatory matters.
