The Constitution of India is the lengthiest written constitution in the world. Originally in 1949, it comprised a Preamble, 395 Articles divided into 22 Parts, and 8 Schedules. Through subsequent constitutional amendments, it has expanded to over 470 Articles arranged in 25 Parts and 12 Schedules.
- Geographical Factors and Vast Diversity: The colossal size of the Indian subcontinent and its unmatched social, cultural, linguistic, and ethnic diversity required detailed safeguards for various communities and regions.
- Historical Influence of the Government of India Act, 1935: The 1935 Act was itself an exceedingly lengthy, cumbersome statute. The framers drew extensively upon its administrative framework and institutional mechanics.
- Single Unified Constitution: Unlike the United States, where the federal union and each individual state possess separate constitutions, India has a single comprehensive constitution governing both the Union and the States (except Jammu and Kashmir until 2019).
- Dominance of Legal Luminaries: The Constituent Assembly was heavily composed of eminent lawyers and jurists (such as Dr. B.R. Ambedkar, Alladi Krishnaswami Ayyar, and K.M. Munshi) who sought to anticipate every potential constitutional contingency and minimize ambiguous grey areas.
