<P> It is imposed for an initial period of six months and can last for a maximum period of three years with repeated parliamentary approval every six months . The 42nd amendment act of 1976 extended the initial time duration of state emergency from 6 months to 1 year . Subsequently , 44th CAA 1978 restored the 1 - year period back to 6 months . Originally , the maximum period of operation of state emergency was 3 years . This 3 - year period was divided into 1 year of ordinary period and 2 years of extra ordinary period for which certain conditions are to be fulfilled . Therefore , from now on after every 1 year Parliament needs to approve the same . If the emergency has to be extended for more than three years , it can only be done by a constitutional amendment , as has happened in Punjab and Jammu and Kashmir . </P>
