<P> A state emergency is declared on failure of constitutional machinery in a state . Every state in India except two states, Chhattisgarh and Telangana has been under a state of emergency at some point of time or the other . The state of emergency is commonly known as' President's Rule' . </P> <P> If the President is satisfied, based on the report of the Governor of the concerned state or from other sources, that the governance in a state cannot be carried out according to the provisions in the Constitution, he may declare an emergency in the state . Such an emergency must be approved by the Parliament within a period of two months . </P> <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> <P> During such an emergency, the President can take over the entire work of the executive, and the Governor administers the state in the name of the President . the Legislative Assembly can be dissolved or may remain in suspended animation . The Parliament makes laws on the 66 subjects of the state list (see National emergency for explanation). All money bills have to be referred to the Parliament for approval . In this occasion ministers of state legislature do not perform actions in state . </P>
