In a groundbreaking episode of The Animal Law Podcast, we explored radical new concepts that could fundamentally transform how constitutional law treats animals. Host Mariann Sullivan welcomed Cambridge University’s Raffael Fasel and Queen Mary University’s John Adenitire to discuss their book “Animals and the Constitution: Towards Sentience-Based Constitutionalism” – a work that challenges centuries of legal tradition by proposing constitutional frameworks that recognize the inherent worth of all sentient beings.

While traditional constitutions rely on the “hypothetical consent of the governed,” this revolutionary approach acknowledges that billions of sentient beings are governed by constitutional systems but have no voice in shaping them. The authors argue for a dramatic shift from anthropocentric legal structures to ones that provide “due concern” for all creatures capable of experiencing pain, pleasure, and complex emotions.

Key Discussion Points:

• The historical evolution of constitutionalism from divine right monarchy to modern democratic systems
• Why sentience, rather than rationality or autonomy, should be the foundation for constitutional worth
• How existing animal welfare protections in constitutions worldwide fall short of true recognition
• The application of proportionality principles when animal and human interests conflict
• Practical challenges of implementing constitutional rights for domesticated and wild animals
• The role of micro-boards and participatory democracy in determining animal interests
• Real-world examples from Ecuador’s rights of nature to Switzerland’s animal dignity provisions
• Why this “realistic utopia” framework offers hope for incremental progress toward comprehensive animal rights

This episode challenges listeners to reconsider fundamental assumptions about law, democracy, and moral consideration – making complex constitutional theory accessible to animal advocates seeking systemic change.
