Which terms were recently upheld by the Supreme Court as being part of the Indian Constitution's Preamble?

The Supreme Court dismissed petitions challenging the constitutional validity of the 42nd amendment, which added ‘secular’ and ‘socialist’ to the Preamble during the Emergency in 1976. The court stated these terms have gained widespread acceptance and clarified that the Parliament’s power under Article 368 allows for amendments, including those to the Preamble. The ruling emphasized that the Constitution is a living document, reflecting the evolving interpretation of these concepts in Indian society.
