<p>Democracies in Europe fail to take adequate climate mitigation measures. In response, not only legal, but also illegal acts of climate protesters are multiplying in Europe. This paper examines the criminalisation of climate protests in France, Germany, Switzerland, and the UK. Against the overarching concept of dissensus to which this special issue is dedicated, this contribution reflects on the role of judges who deprive the disobedient from the opportunity to communicate about their motives. The paper pays particular attention to the case of David Nixon in the UK, in which the judge prohibited Mr. Nixon from sharing his motivation or mentioning climate change in the court room. This demeans civil disobedience to an ordinary criminal act and deprives democracy of its self-correcting potential.</p>
