Explanation:

• On April 24, 1973, the Supreme Court, with its then full strength of 13 judges, ruled in the Kesavananda Bharati case that secularism was part of the basic structure of the Constitution.
• It also held that elements constituting the basic structure were beyond Parliament’s power to amend the Constitution.
• The court reiterated this principle in 1994 in the S.R.Bommai case when dealing with the challenge to the dismissal of four Bharatiya Janata Party-ruled State governments after the demolition of the Babri Masjid.
