The case studies throw up a wealth of factors, but two major factors stand out, one structural, the other agential. The major structural factor is federalism. In the three federal nation-states the national jurisdiction shares power and competencies with subnational jurisdictions, with implications for human rights legislation at the federal level. This contrasts with the UK, a unitary state, but with its sovereignty now constrained by the European Union. The major agential factor is the nature, institutional location and timing of activism promoting human rights. The study highlights several prominent political and academic actors, who initiate new policy proposals in response to (and utilising) critical junctures in the history of human rights institutions in each country. The thesis concludes by indicating that a fertile area of future research lies in the exploration of the lineage, transmission and development of the ideas centred on human rights and justice argued by such entrepreneurs.
