Act vs. Rules: Understanding the Differences
An Act is substantial law, while a Rule is procedural law. This means that an Act is something done by law or by force of law, regardless of whether the person executing it is willing or not. According to the General Clauses Act, the meaning of a Rule is "a rule made in exercise of a power conferred by any enactment, and shall include a regulation made as a rule under any enactment." This definition was provided by the Hon'ble Apex Court of India in the case titled Sukdev Singh vs. Bhagatram Sardar Singh – AIR 1975 SC 1331.
