The legislature versus judiciary debate has gone up a notch after the Rajya Sabha chairman Jagdeep Dhankhar's comments and the sharp reaction of the Congress. While Mr Dhankhar has questioned the basic structure doctrine and indicated that the judiciary should know its limits, the Congress has declared that he should "get back to textbooks" and the "Constitution is supreme, and not the legislature". Mr Dhankhar's criticism of a 1973 supreme Court judgment considered a landmark, was an "extraordinary attack on the judiciary," the Congress said.
