India's Parliament Winter Session 2025 commenced on December 1, 2025 and ran until December 19, 2025. The session saw the introduction and passing of landmark legislation. The most significant was the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Bill, 2025, which replaced the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010.

The SHANTI Bill was tabled in Lok Sabha on December 15, passed on December 17, cleared by Rajya Sabha on December 18, and received Presidential assent on December 20. The liability framework introduces a tiered structure ranging from ₹100 crore to ₹3,000 crore based on plant capacity. The session also witnessed passage of a Bill to replace the MGNREGS Act, insurance law amendments, tobacco excise duty bills, and financial reform legislation. In total, 10 Bills were introduced in Lok Sabha and 8 Bills were passed by both Houses during the session. The opening of the Winter Session signalled a heavy legislative agenda focused on energy transition, economic reform, and labour welfare.
