Within: Environment

CMS' environmental team works with other departments of the firm (including tax, real estate and corporate) to provide end-to-end support to clients in litigation, corporate and real estate transactions, development projects and day-to-day advice. Jointly led by counsels Ivan-Serge Brouhns and Gregory Verhelst, the group provides assistance with a broad cross-section of standalone environmental issues, such as waste, industrial emissions and noise. It also handles environmental matters as they relate to the energy sector (particularly wind energy), as well as town planning. Verhelst and associate Bert Van Weerdt acted for Aspiravi on the development of several onshore wind farms in Flanders. Brouhns was the lead adviser to Tesla on the application of Belgian environmental legislation to the Tesla Powerwall storage battery. The firm also acts for other clients, such as Honeywell, EDF Luminus, the Walloon Region and the City of Brussels.

  • Access to justice: protective costs orders in planning challenges

    Third parties and competing developers have no rights of appeal to the Secretary of State against planning decisions. Disappointed applicants can appeal to the Secretary of State and can have the merits of the application reconsidered. The only remedy available to a disappointed third party is a challenge by way of judicial review in the High Court on a point of law. The sense of frustration and disempowerment this creates has not been helped by the increasing complexity of the planning process and the use of consultation to legitimise decisions that many perceive may already have been taken.
