LL.B. (Hons) University of Sheffield.

David Armstrong read law at the University of Sheffield. He was admitted as a Solicitor in 1990 and began his career as a litigator in private practice, eventually taking up a position as Head of Litigation of a Metropolitan Local Authority. David is highly experienced in all areas of local authority management, regulation and contentious work, from ASB, housing and environmental to licensing and planning enforcement.

David returned to the private sector in 2001, practising as a Solicitor Advocate and as a specialist consultant to local and national government and national agencies prior to his Call to the Bar.

David is widely acknowledged nationally as an expert in local authority and public sector management, contentious and regulatory matters, with a particular specialism in environmental, ASB and housing regulation. Confirming his place as a nationally acknowledged expert, David acted as the Defra nominated Chair of the host Boroughs’ 2012 Olympic coordinating committee.

David has conducted all forms of court proceedings, both civil and criminal, at various levels. In 2015 David obtained the country’s first ASB Crime and Policing Act 2014 injunction from the High Court to prohibit traveller incursions across the Borough of Blackpool and in 2016 he obtained the country’s first rogue landlord Criminal Behaviour Order following a Housing Act 2004 prosecution. David had conduct of the largest food prosecution case ever brought by a local authority in England, requiring coordination of 27 warrant searches and over 400,000 exhibits. David also, notably, had conduct of two significant Court of Appeal cases concerning education catchment areas, and won the first appeal test case on the scope of Part I Environmental Protection Act 1990 authorisations.

As a result of his specialist support and consultancy work with Mallard Consultancy, Defra and agencies such as Keep Britain Tidy, Keep Wales Tidy, Chartered Institute of Wastes Management, Chartered Institute of Environmental Health and Keep Northern Ireland Beautiful, David is known to officers and legal departments of local authorities throughout the country as “the Wig”.

David has worked with central government on the drafting of key environmental legislation and authored several of Defra’s guides on environmental regulation, including those relating to litter and waste regulation, litter clearing and street litter control. He has also been a Solicitors Regulation Authority accredited CPD trainer to the legal profession since 1996.

He is particularly renowned for his creative approach and his ability to find solutions or pathways for clients, and often where traditional approaches have failed. David relishes a challenge and is known for his positive approach and tenacity on behalf of his clients.

David is available for instruction nationally.
