Hi there.

The notion of basic structure is only a judicial creation designed to prevent Parliament from abusing its power of modification. The concept is that the fundamental aspects of the Indian Constitution should not be changed to the point that the Constitution's uniqueness is lost.

The idea of fundamental structure supports that the Indian Constitution upholds certain principles that are the governing norms for the Parliament; any amendment cannot modify these principles. The theory as we know it now did not always exist, but it has been propounded and defended by the country's judicial officials over the years.
