The Legal 500 2019

Alastair acts for clients in the public and private sector promoting and opposing major infrastructure schemes and advising on legislation and public law.

His infrastructure work requires specialist knowledge of planning law, compulsory purchase, environmental and highways law and practice.

His recent work includes advising clients on transport and energy related development consent orders (DCOs), in particular on strategic highway, off-shore wind farm and nuclear power proposals (including advising on a significant proportion of highway DCOs, a number of energy DCOs for objectors and for Suffolk County Council on Sizewell C).

He also promotes legislation for public and other bodies that require additional statutory powers, requiring knowledge and expertise in all aspects of public law and regulatory work.

As a Roll A Parliamentary Agent, Alastair is one of a very small number of lawyers entitled to promote and oppose private and hybrid legislation in Parliament and since he qualified, he has promoted more private Bills in Parliament than any other agent.

He has also acted on most of the major infrastructure projects that have attracted parliamentary scrutiny, including Crossrail and HS2 (acting for most local authorities and a number of significant landowners and national organisations).  He drafts primary and secondary legislation (including rules and charters) and advises on Bill amendments and Parliamentary procedures.

Alastair’s recent work includes acting for central government, local government, major developers and transport bodies including highway authorities, rail interests and port and harbour authorities.

Alastair has been ranked in the top tier of the parliamentary section in Chambers UK and the Legal 500 for a number of years.
