RWE has tried to intimidate activists by sending out declarations to cease and desist before, in 2012 and 2013.
One court case took place in 2012.
Activists fought back against the repression through civil law with a campaign in 2013. People were invited to send declarations to cease and desist to RWE themselves, asking the energy company to cease to mine for coal.
