Niall Michel


A Client Choice™ award winner and recommended by Legal 500, Niall is a litigation partner on our Tier 1 ranked Public, Regulatory & Investigations team.

Amongst other things, he shares his industry-leading experience and expertise with clients in the regulatory sphere.  A large part of his practice is in the areas of sectoral and professional regulation, and professional discipline.  In particular, he advises clients extensively in the areas of financial services, utilities, aviation and legal services regulation.  Here, he assists both regulators and regulated persons in navigating complex issues, including compliance, regulation, supervision, investigation and enforcement.  He frequently advises and represents clients in optimally navigating through regulatory and other investigations and inquiries.  This includes guiding clients on the exercise of regulatory powers, the procedures to be followed, the rights and obligations of the parties involved, and on the extent of information and document-provision that can be expected or required.
