A legal challenge on air quality grounds to the 2017 adopted local plan for the Canterbury district was considered by a high court judge on 21 March. 
The case, which was brought by Emily Shirley, a local environmental campaigner, was adjourned pending the decision of the Court of Appeal regarding an earlier high court case not to cancel the decision of the Secretary of State not to decide for himself the planning application for the contentious Mountfield Park development. Hearings on both cases are expected in the summer this year.
