A High Court judge is expected to rule within weeks on whether or not planning permission at a quarry in Lizard Peninsula beauty spot was lawfully approved.

Action group Cornwall Against Dean Superquarry (CADS) who brought the appeal, led by Silke Roskilly, were at the High Court in Bristol on Friday after bringing the appeal against Cornwall Council for granting permission to quarrying company Shire Oak without an Environmental Impact Assessment (EIA).

In a statement following the hearing, spokesperson Alison McGregor said: "This [the result] is not expected today and may take two or more weeks to reach a conclusion.

"CADS believe that today's hearing went well for Silke Roskilly and her legal team from Stephens Scown LLP. We were encouraged that the arguments they put forward were well constructed and carefully considered by The Hon. Mr Justice Dove.

"As this is a UK planning test case of national environmental importance we at CADS are not surprised that The Hon. Mr Justice Dove requires time to carefully consider the evidence before making a decision."

In April the council granted permission for the work, which includes a perimeter fence, fuel and explosive storage, and office, reception and amenity areas, but Greg Clark, Secretary of State for Communities and Local Government, overturned the decision due to the lack of an EIA.

He said the scale of the quarry merited an assessment, and concerns were also raised that it had not been considered along with expected proposals to build a jetty and 500 metre breakwater out into a nearby Marine Conservation Zone.

Chris Tofts of Stephens Scown said: "It was clear that the judge was critical with the way that Cornwall Council had handled aspects of the planning application. This case turns on a novel point of law and due to the impacts it may have, the judge may wish to seek the views of the Secretary of State before giving his judgment."
