The theoretical research methodology examines the historical development of
the theory of law itself and frequently uses theory as a springboard to critique
existing law, legal reform and practice. The model for reform research is based
on the research methodologies used within the law reform commissions to
provide advice on changes to existing law. While public policy research has
many common aspects with law reform research, it emanates from within
government and hence tends to have a more pragmatic approach.83 These
expanded frameworks often incorporate empirical research methodologies into
traditional doctrinal methodologies, at least to some extent.
