She also acted for the Council in the Proceeds of Crime Act proceedings in the Crown Court.
    • Junior counsel acting for the London Borough of Enfield in Koumis v Secretary of State for Communities and Local Government [2014] EWCA Civ 1723 regarding whether an erroneous notice under s.173A of the 1990 Act, purporting to vary an existing valid enforcement notice, rendered the enforcement notice a nullity.

    • Emmaline acted for Ashford Borough Council in the case of R (oao Camilla Swire) v Ashford Borough Council [2021] EWHC 702 (Admin) in which the Council had issued a lawful negative screening opinion but the grant of planning permission for a winery in the AONB was challenged; there had to be a change in circumstances after the screening opinion and that change had to be rationally capable of leading to a change in the view that the development was not EIA development for an issue under regulation 3 to arise.
    • Emmaline acted for the local authority in Gardiner v Hertsmere BC [2021] EWHC 1875 (Admin) and in the subsequent proceedings in the Court of Appeal, regarding whether the self-build exemption from the community infrastructure levy, provided for in the Community Infrastructure Levy Regulations 2010 was available if development had first been authorised by retrospective planning permission under s.73A of the Town and Country Planning Act 1990.
