This book explores the legal conception of personhood in the context of contemporary challenges, such as the status of non-human animals, human-animal biological mixtures, cyborgisation of the human body, or developing technologies based on artificial autonomic agents.

This book analyses a middle position between single enumerations in a regular federal-like and a regular autonomy-like distribution of legislative powers by examining constitutional legislation in three countries (Canada, Denmark and Finland) that have established separate enumerations for the national level and the sub-state level.
