In political science, constitutional autochthony is the process of asserting constitutional nationalism from an external legal or political power. The source of is the Greek word αὐτόχθων translated as springing from the land. It usually means the assertion of not just the concept of autonomy, but also the concept that the constitution derives from their own native traditions. The autochthony, or home grown nature of constitutions, give them authenticity and effectiveness. It was important in the making and revising of the constitutions of Bangladesh, India, Pakistan, Ghana, South Africa, Sierra Leone, Zambia and many other members of the British Commonwealth. This proposition found doctrinal support in the influential theory propounded by the legal philosopher, Hans Kelsen, which had it that it was inconceivable for a legal system to split into two independent legal systems through a purely legal process. One of the implications of Kelsen’s theory was that the basic norm of the imperial predecessor’s Constitution would continue to be at the helm of the legal system of the newly liberated former colony despite the legal transfer of power, precisely because the transfer of power was recognised as ‘legal’ by the Constitution of the imperial predecessor.
Independence was formally granted to India by the enactment of the Indian Independence Act 1947 though the executive decision to grant India independence was arrived at earlier in the Cabinet Mission Plan in 1946. It was under this Plan that the Constituent Assembly was envisaged and charged with the mandate of drafting the new Constitution for India. This was legally recognised in Section 8 of the Independence Act. The Cabinet Mission Plan had envisaged that the new Constitution would be put to the Crown-in-Parliament for approval. The framers introduced two deliberate procedural errors in the enactment of the Constitution of India in violation of the Independence Act:
They did not put the Constitution to the approval of the either the British Parliament as envisaged by the Cabinet Mission Plan or the Governor-General as envisaged in the Indian Independence Act 1947;
Following the Irish precedent, Article 395 of the Constitution of India repealed the Indian Independence Act — something the Constituent Assembly did not have the authorisation to do.
In doing so, the framers not only repudiated the source which authorised them to enact the Constitution but it was also a denial, albeit symbolic, of Indian independence being a grant of the imperial Crown-in-Parliament.
