That being said, the adoption of English Common Law has been a major competative advantage for India. It was this, more than anything else, that truly was beneficial in terms of concepts brought from the UK.
Indian legal system is not simply an adoption of English Common Law. Thats a misconception that many people have. Many of the British laws were modified post independence. In fact it is more of an amalgamation of Irish, French and American and British system adapted to Indian tradition. In other word, its an “Indian product” whose individual components comes from many different sources.
BTW India has a single written and codified contstitution, while Britain does not.
