The European Court of Human Rights (ECtHR) announced on Friday, 29th April, that the Swiss Climate case will be dealt with by the Grand Chamber. In this blog post, I focus on a key aspect of the admissibility issues in relation to articles 2 and 8 (the right to life and the right to private life). The question of how the Court will interpret victim status in this case will tell us more about how Court defines its engagement with complex, urgent and large-scale threats to human rights and its understanding of subsidiarity in a context in which political and scientific factors are particularly prominent.
