Past Notable Cases


CAN Europe intervention in the People’s Climate Case (2018) 
Garden Court barristers are representing CAN (Climate Action Network) Europe on its application to the European General Court to intervene in the People’s Climate Case. This is a case in which families and youth have challenged the EU in order to protect their fundamental rights from the insufficiency of the EU’s 2030 greenhouse gas emission reduction target. See coverage in The Independent.

Representing the Mayor of Malton in legal action against planned government changes to how fracking applications are handled (2018) 
The Government issued a written ministerial statement requiring local authorities to ‘recognise’ the statutory definition of fracking set out in the Infrastructure Act 2015. Applying that definition, which relates to the volume of fluid used in the process, rather than the nature of the process itself, could lead to fracking operations (which use slightly less fluid than the statutory threshold) being granted planning permission in areas of outstanding natural beauty and national parks, such as the North York Moors. See BBC coverage.

Work on Barbuda international airport halted by interim injunction (2018) 
The injunction was granted after the case was lodged outlining concerns about environmental damage that the Barbudans who brought the case, John Mussington and Jacklyn Frank, believe the project will cause. Department of Environment documents obtained by Mussington and Frank’s legal team revealed that the authorities had been warned about ecological as well as archaeological risks. See coverage in The Guardian.  

Anti-fracking campaigner pursues Supreme Court challenge in bid to overturn Government decision to approve fracking in Lancashire (2018)
Representing anti-fracking campaigner Gayzer Frackman. This is the first case in which a court has had to consider whether planning permission can be granted for shale gas exploration wells without the need to take account of the greenhouse gas emissions resulting from shale gas production at the same wells. See coverage in The Guardian.

Greenpeace India
Garden Court has been engaged in six cases in the Indian High Courts to defend Greenpeace India’s right to freedom of expression.  We have been successful in each case.

Oil and gas drilling licences in Norway
In Norway, we have worked on a lawsuit challenging the government’s grant of oil and gas licenses to 13 companies planning to drill in the dangerous and ecologically fragile Arctic.

KK & ors v AML (England & Wales High Court)
Garden Court Chambers represented 142 villagers who live near a large iron ore mine in West Africa. The claimants sought damages for personal injury, death and other damage allegedly caused by the actions and negligence of African Minerals Ltd, the British company that owns the mine.

Coal expansion in Turkey
The Turkish government planned over 60 new coal fired power stations, claiming that “energy security” makes it unnecessary to conduct environmental impact assessments, as required by international environmental law.  We worked on an amicus brief in support of a constitutional law challenge to this extreme threat to the health of people in Turkey and neighbouring states.

Legal Response Initiative
We have worked with the Legal Response Initiative to advise developing nations and charities on the UN Climate Change negotiations and the enforcement of the resulting Paris Agreement. The Legal Response Initiative provides legal support to poor and climate-vulnerable developing countries – on public international law issues encompassing environmental law, treaty law and human rights law.

defending environmental protestors

Garden Court is renowned as one of the leading chambers in the UK specialising in civil liberties, human rights and criminal defence. We are ranked as a leading chambers in both the Legal 500 and Chambers & Partners for our expertise in these areas of law. 

Our barristers have considerable experience defending environmental protesters in criminal proceedings, including: 

  • Greenpeace activists
  • Anti-fracking protestors
  • Anti-GM crop protesters
  • The ‘Heathrow 13’
  • G20 Climate Camp protesters 

We have pursued legal action in the High Court on human rights grounds against energy companies, such as Ineos and UK Oil & Gas, who seek draconian injunctions to restrict the legitimate right to protest. 

Our barristers have authored the key text on protest rights, The Protest Handbook.


international environmental law

Significant international work has included cases concerning land rights, corporate responsibility, oil exploration and drilling. 

Recent significant cases include legal action taken against the Government of Antigua & Barbuda on behalf of Barbudans affected by and opposed to the destruction of ancient forests, rare wildlife and sensitive ecosystems associated with the construction of an international airport on Barbuda. The legal action resulted in an interim injunction granted by the High Court of Antigua & Barbuda, which halted all construction on the airport. 

Through the Global Legal Action Network, our barristers are pursuing a high profile legal challenge in the European Court of Human Rights against the governments of Europe over their failure to cut green house gas emissions. 

Our barrister, Richard Harvey, is currently a consultant to Greenpeace International, assisting them with carrying out their environmental mission around the world.


funding your case

Given some of the difficulties in obtaining legal aid for these cases, we do our best to work with other funding arrangements, including ‘no win, no fee’ agreements where appropriate, fixed fees for some matters and crowd funding.

In some cases legal action to protect the environment is protected by the Aarhus Convention, which limits the amount a claimant would have to pay a defendant if the claim is unsuccessful. The limit is £5,000 for individual claimants and £10,000 for group claimants. The Aarhus regime also imposes a cap of £35,000 to limit the amount a successful claimant can claim from a public body.
