Exemplifying a comprehensive environment and planning offering, McCann FitzGerald LLP is particularly well-placed to guide domestic and international clients through consenting processes and regulation for infrastructure projects, notably in the transport and energy sectors. The team provides strategic advice on a range of contentious and non-contentious mandates, including those related to transactions, complex environmental assessments and the prosecution and defence of judicial review challenges. The team is jointly led by expert Brendan Slattery, who specialises in energy security and the delivery of significant local and national projects; and Michelle Doyle, who is a strong choice for regulatory guidance and contentious mandates. Sinéad Martyn is another key lawyer for advice on onshore and offshore project developments, judicial review defence, and transactional and regulatory support.
