Features of Emergency:

Once an emergency is proclaimed, the federal distribution of powers remains practically suspended and all the powers are concentrated in the hands of the union government. Secondly, the government also gets the power to curtail or restrict all or any of the Fundamental Rights during an emergency. From the wording of the provisions of the Constitution, it is clear that an Emergency is seen as an extraordinary condition in which normal democratic politics cannot function. Therefore, special powers are granted to the government.
