Theorising Evidence Law.

What does it mean for a specialist department of legal studies, such as the Law of Evidence, to have, or to acquire, 'philosophical foundations'? In what sense are the theoretical foundations of procedural scholarship and teaching distinctively or uniquely philosophical? The publication of Philosophical Foundations of Evidence Law (OUP, 2021), edited by Christian Dahlman, Alex Stein and Giovanni Tuzet, presents a valuable opportunity to reflect on these existential questions of disciplinary constitution, methodology and design. This review article critically examines the volume's idiosyncratic selection of topics, structural taxonomy, epistemological priorities, and enigmatic thesis that modern evidence law is turning from rules to reasons as its organising intellectual framework. Whilst the volume is impressively interdisciplinary and cosmopolitan in authorship and outlook, some doubts are expressed about its implicit US orientation, limited engagement with institutional or doctrinal details, and marginalisation of normative criminal jurisprudence.
