The Bharatiya Nyaya Sanhita (BNS), 2023, aims to replace the Indian Penal Code, 1860. - A) It does not remove sedition entirely; it redefines it. - B) Community service as a punishment for petty offences has been introduced. This is a significant change. - C) It does not abolish the concept of cognizable and non-cognizable offences. - D) Laws enacted by Parliament typically come into effect upon receiving presidential assent, and their applicability is not retrospective unless explicitly stated. The BNS is not stated to be retroactive. However, the introduction of community service is a novel aspect.
