Article 368, the three ways to amend the Constitution, and the basic structure doctrine that limits Parliament's power.
Article 368 lays down the formal procedure for amending the Constitution. India's amendment process is neither purely rigid (like the US) nor purely flexible (like the UK) β it's a deliberate middle path, with different provisions requiring different levels of difficulty to amend.
Can Parliament amend any part of the Constitution, including Fundamental Rights? This question went through several twists: Golaknath (1967) said FRs cannot be amended at all; Kesavananda Bharati (1973) overturned this, holding Parliament can amend any part, including FRs, but cannot alter the "basic structure" of the Constitution β a limit not written anywhere in the text, but read into it by the judiciary.
The 42nd Amendment, 1976 (often called the "Mini-Constitution") made sweeping changes, several of which were later reversed by the 44th Amendment, 1978, once the political climate that produced the Emergency had passed.
