<h1>India Backs COP30, Faces Article 240 Chandigarh Row and NSA Detention Challenge as Justice Surya Kant Becomes CJI</h1> India has pledged support to Brazil's COP30 presidency and welcomed recent climate summit decisions, while domestically a proposed constitutional amendment to place Chandigarh under Article 240 faces opposition from regional leaders and political parties, raising federalism and governance concerns. The Centre's move to appoint an independent Chandigarh administrator has drawn criticism, though the ruling party's state unit asserts Chandigarh remains integral to Punjab. The Supreme Court will hear a petition challenging a climate activist's detention under the National Security Act as unconstitutional and violative of fundamental rights. Separately, Justice Surya Kant will assume office as the 53rd Chief Justice of India, impacting future constitutional and civil liberties jurisprudence.
