STATE LAWS Whereas the Federal acts exempt cooperative associa- tions, when they have comped with certain regulations, from paying income taxes and from being viewed as operating in restraint of trade, State acts deal primarily with methods of control, property rights, restrictions of transfer of certificates of membership or capital stock, rights to make specific kinds of contracts between the association and its members, as well as operation in restraint of trade within the state. Before there was any Federal legislation favoring co- operative associations many of the states had provided special acts for the benefit of cooperative associations. The need for special legislation for cooperative associa- tions was apparent because it was difficult under the general corporation laws of the various states to operate an association primarily for the benefit of its users. There are three reasons why this was true. First, cooperative associations could not restrict the transfer of stock to non-patrons. Second, they could not limit the amount of stock held by one person. Third, no method of control was provided other than on a share basis. Consequently stock often drifted into the hands of a few who were more interested in operating the association for profit than for rendering service to the patrons.
