This work investigates the complex intersection between legal frameworks and the ontological status of non-human animals. The authors, Edward Mussawir and Yoriko Otomo, utilize critical legal theory and post-humanist philosophy to examine how the law constructs, categorizes, and regulates the existence of animals. By analyzing historical and contemporary legal precedents, the text argues that the law functions as a primary mechanism for defining the boundary between human subjects and animal objects.

Scholars in the field of critical animal studies and legal theory identify this text as a rigorous contribution to the discourse on non-human rights. Readers frequently note the dense, academic prose that requires a foundational understanding of jurisprudence and continental philosophy.
