The Model Byelaws are issued by the office of the Commissioner of Co-operation. Copies of the latest version of the byelaws are available from the office of the Mumbai District Co-operative Housing Federation Ltd. near Horniman Circle. Most probably the 2014 issue is the latest. The Byelaws have to conform to the Maharashtra Co-operative Societies Act, 1960 and the Rules, 1961.Hence when the Act is amended the Byelaws get revised, if necessary, though it does not always happen. There were amendments to the Act in 2018 or 19 by the Fadnavis Government. Soon the Government changed. I do not know whether the amendments affect the Byelaws. They affect the election processes. The election processes themselves are on hold due to Covid.
