Bro, this is not a car or machinery that has become old. Laws rules and regulations are enacted at some point in time and remain applicable throughout until repealed. The do get amended from time to time to adjust any required parameters.
Quran ( A complete code of life) - more than 1400 years ago
Pakistans Consituition - 1971, Sales Tax Laws - 1990, Contract Act - 1872, Sales of Goods Act - 1930
Penal Code of Pakistan - 1860
The point being, a law or rule doesnt have to be of today, it could have been established at any point of time
