Chief Justice of India DY Chandrachud on Saturday called the basic structure doctrine a North Star that guides and gives certain direction to the interpreters and implementers of the Constitution when the path ahead is convoluted. The remarks by the CJI came against the backdrop of the recent remarks by Vice President Jagdeep Dhankhar who questioned the landmark 1973 Kesavananda Bharati case verdict that gave the basic structure doctrine. Mr Dhankhar had said the verdict set a bad precedent and if any authority questions Parliament's power to amend the Constitution, it would be difficult to say "we are a democratic nation".
