Horse Hill: Court of Appeal to hear challenge to controversial oil drilling permission

  • UK government to defend council’s controversial decision in court
  • 9am, campaigners with placards will gather outside the Royal Courts of Justice on the Strand to mark their opposition to oil drilling at Horse Hill

A woman who opposes Surrey County Council’s decision to allow oil drilling in greenbelt countryside, near Gatwick airport, is taking her legal battle to the Court of Appeal today.

The challenge has been brought by Sarah Finch, supported by the Weald Action Group, and is due to last a day and a half.

Permission for the oil drilling was granted by Surrey County Council in 2019, just months after it declared a climate emergency.

Friends of the Earth has been given permission to intervene in the challenge and will support Sarah’s case. The UK government has also been given permission to take part in the  case as an interested party and is defending the decision by Surrey County Council.

It is estimated that the development could lead to more than 10 million tonnes of CO2 equivalent being released into the atmosphere when the oil is ultimately burned.

The legal challenge centres around Surrey County Council’s decision not to take into account the full climate impact of the oil development in the context of the current climate emergency.

The Court of Appeal will be asked to rule on whether the environmental impact assessment used as part of the decision-making process should have considered all the climate impacts of the development – including greenhouse gas emissions arising from the burning of the oil produced at the site when it is actually used. That is where the majority of emissions will arise.

This legal challenge is likely to have wide-ranging implications. The High Court’s original judgement that Surrey County Council did act lawfully is already being cited by other fossil fuel developers to try to justify excluding GHG emissions that aren’t operational emissions.   For example, West Cumbria Mining Limited sought to do this in the recent Whitehaven coal mine planning inquiry.

Sarah Finch said: 

“If Councils don’t assess all the climate impacts of a proposed development before giving it permission, then we have no chance of reaching net zero. Surrey County Council didn’t do this in the case of Horse Hill, which I believe was wrong, legally as well as morally.

“The Prime Minister said at COP26 ‘If we don’t get serious about climate change today, it will be too late for our children to do so tomorrow’. He’s right. And getting serious means leaving fossil fuels in the ground.”

Friends of the Earth lawyer, Katie de Kauwe, said:

“Granting planning permission for more oil extraction in the middle of a climate crisis without considering its full impact on our planet is ludicrous, and, as our legal team will argue, also unlawful.

“A number of other countries assess ‘end-use’ emissions as part of their environmental impact assessments, the UK should too.

“It’s astonishing that the UK government is defending this decision in court, only days after the conclusion of COP26. So much for its commitment to building a carbon-free future.

“We’re proud to be backing Sarah’s legal challenge. In the wake of weakness from both the government and Surrey County Council, she is standing up strongly for both her community and our environment.”

Leigh Day solicitor, Rowan, Smith said:

“The eyes of the world are on Glasgow right now, and as Governments around the world re-commit to step up action in response to the climate emergency, the Court of Appeal will this week consider a hugely important case for the future of the planet.

“Our client, and the campaigners she represents, make a simple point: Surrey Council cannot lawfully grant planning permission for the production of fossil fuels without first assessing its total climate change impact, including the carbon emitted when the fuels are burned. Our client hopes that the Court of Appeal will reverse the earlier judgment and conclude that planning permission ought to be quashed on that basis.”
