The Constitution of India strengthens the system of adoption of amendments that can quickly change the basic law of the country. Most of the amendments are adopted by Parliament in a rather simple way.

The draft of amendment is made by a deputy to one of the Houses of Parliament.

After receiving approval in each chamber (2 / 3 vote), it is transmitted to the president, who must sign it. After this Amendment the Act comes into force and is inserted in the text of the Constitution.

For the most important articles, a more complex procedure is used: after the adoption, but before transfer of the amendment to the President for signature, it must be ratified by not less than half of legislative meetings of the states.

The high degree of effectiveness of the Constitution of India is provided in a certain degree by particular flexibility of constitutional regulation and the application of combined flexible-rigid order of its change.

This applies to economic relations, the legal status of rights, diversity of federal relations, electoral law, as well as the provisions of the most socially disadvantaged groups.
