At the bottom of the following quote from Greenpeace you'll find a Q&A on the law - just click the link
Landowners near Fernhurst, Sussex have signed up to our Wrongmove legal block, denying permission for fracking on their land which sits inside the South Downs National Park. So when Celtique Energie marched into town they found the site they had permission to drill on was surrounded by a legal block. If they drill sideways more than a few hundred meters in any direction they will break the law. This makes it nearly impossible for them to operate.
This tactic is being replicated across Britain with more than 25,000 people signed up to the legal block. But the government is fighting back. Ministers are considering changing the law to allow fracking under people’s homes without the owner’s permission. However, changing a long-established piece of law such as this is not easy, will take a long time and would require a vote in Parliament. It is not something they can simply do.
In the meantime, the law stands. If you do not give them permission, they cannot drill. Join the legal block and make your own check-mate move against fracking.
