'What should we do when those who wield power fail? In a subtle and nuanced analysis, Michaela Hailbronner tackles this question with insight and originality. Drawing on case-studies from comparative constitutional law, the European Union, and international law, Hailbronner makes a powerful case that we need to take institutional failure seriously - not just as a cause for lament or an automatic licence to deviate from established legal norms, but as a stimulus for a more measured and context-specific approach. All public lawyers will benefit from engaging with Hailbronner's illuminating and compelling arguments.' Aileen Kavanagh, Professor of Constitutional Governance, Law, Trinity College Dublin
