(Not) Proving the Public Good: Scientific Evidence and the Margin of Appreciation
Abstract The article offers a critical look at the complex relationship between the European Court of Human Rights (ECtHR) and policy-supportive (scientific) evidence. In particular, due to now commonplace, evidence-based policy-making of national governments, the Court is effectively supplemented with various statistics and studies and tasked with reviewing policy measures aiming to improve the public good. This article investigates the ECtHR’s use and interpretation of policy-supportive evidence in the proportionality analysis, and how this affects the margin of appreciation. The recent case of Dubská and Krejzová concerning the ban on home births, which the article explores in detail, is illustrative in this regard. Although the Court appears to review scientific evidence substantively, an increased proliferation of statistics and studies may bring about controversy in relation to legal cases, without having a conclusive impact upon the outcome of a dispute.
