Nicholas Aroney (University of Queensland - TC Beirne School of Law) has posted The Formation and Amendment of Federal Constitutions in a Westminster-Derived Context (International Journal of Constitutional Law (2018)) on SSRN. Here is the abstract:
This article offers an account of the formation and amendment of federal constitutions in a Westminster-derived or post-Westminster context. The four countries considered are Canada, Australia, India, and the United Kingdom. These countries are chosen for comparison due to their common historical relationship to Britain and the exercise by the British Parliament of sovereign legislative and constitutive authority over their respective territories. While Canada, Australia and India are today constitutionally independent of Britain, and while substantial autonomy has been conferred on the devolved parliaments of Scotland, Wales and Northern Ireland within the United Kingdom, such independence and autonomy were secured differently in each country. Similarly, the constitutional relationship between the federated polity and its constituent polities in each of these countries has evolved in unique ways.
