Research

Stefan’s research interests are broadly in public and constitutional law, as well as human rights. In his recent book Towards the Environmental Minimum (Cambridge University Press, 2021) he argues for the recognition of a comprehensive framework that addresses the relationship between human rights and environmental harm. The argument is based on a unique and comprehensive dataset of the case law of the European Court of Human Rights, along with other regional human rights courts that is freely available for research and teaching purposes here. Stefan has consulted on legal challenges against breaches of air quality and emission targets in Europe, and the legal relevance of environmental harms to humans more generally, notably under the Human Rights Act 1998.

The core research question of his work on free expression and protest is how the law should respond to the prevalence and abuse of private power, especially by structurally dominant online platforms. This may require the law to revisit some of the principles and assumptions underlying conventional offline approaches: chiefly with respect to the scope for legitimate suppression of hate speech as well as the limits that free expression and protest rights impose on the contractual autonomy of social media platforms with their users. Stefan has given interviews to media outlets on questions of free expression and social media, including the BBC World Service and contributed to the on-going internal policy debates of social media platforms, notably on Facebook's Oversight Board Charter.

Beyond human rights, Stefan is generally interested in public and constitutional law, particularly as it operates in the United Kingdom, Germany and the European Union. He spearheaded research in Oxford on the prorogation of the UK Parliament and appeared on BBC News television and various radio outlets outlets to offer legal commentary on the proceedings before the Supreme Court. He writes and blogs frequently on legal developments, often drawing comparisons between legal systems and reflecting on deepening European integration.

Teaching

Stefan lectures on the Constitutional Law paper, the Public Law LLM Seminar Paper and supervises in constitutional law and human rights. These subjects have evolved considerably over the last few years, especially following the constitutional shifts due to Brexit. In Oxford, Stefan lectured on the undergraduate Human Rights Law course and the BCL course Constitutional Principles of the EU.
