European Journal of International Law, Volume 31, Issue 3, August 2020, pp. 797-827 ; Judges and scholars have long debated whether the European Court of Human Rights (the ECtHR or the Court) can only expand, never diminish, human rights protections in Europe. Recent studies have found that political backlashes and national-level restrictions have influenced ECtHR case law. However, analysing whether the ECtHR is shifting in a regressive direction faces an empirical challenge: How can we observe whether the Court is limiting rights over time if it has never expressly overturned a prior judgment in a way that favours the government? We gain traction on this question by analysing all separate and minority opinions of the ECtHR Grand Chamber between 1998 and 2018. We focus on opinions asserting that the Grand Chamber has tacitly overturned prior rulings or settled doctrine in a way that favours the respondent state, which we label as ‘walking back dissents’. We find that
walking back dissents have become significantly more common in the last decade, revealing that some members of the ECtHR themselves believe that the Grand Chamber is increasingly overturning prior judgments in a regressive direction.
