The tortuous thicket of laws, constitutional provisions, presidential orders, political history and legal mystifications surrounding Article 370 and Article 35A make it difficult to navigate through recent debates about its abrogation in an informed way. This series of three essays by Shrimoyee Nandini Ghosh, lawyer and legal researcher, aims to be a somewhat eclectic guidebook— at times proffering a no frills step-by-step road map, at others traversing some rather more unfrequented and adventurous legal diversions. In this first essay, Shrimoyee provides a legal-historical guide to terms like 370, 35(a) and the tricks, which were played to make these history.”
