V. Niranjan (One Essex Court) has posted Legislative Competence: The Union and the States (This appeared in the Oxford Handbook of the Indian Constitution (OUP 2016)) on SSRN. Here is the abstract:
This Chapter analyses a number of controversial questions relating to legislative competence in India. It argues that the current state of the law is unsatisfactory because the Supreme Court has conflated the concept of competence with the quite distinct concept of repugnance. It suggests that, properly analysed: (a) there is no 'aspect theory' under the Indian Constitution; (b) article 254 applies not only to laws passed under List III but also to laws passed under List I or List II; and (c) Mar Appraem Kuri and VK Sharma were wrongly decided.
