Every bill after it is passed by the assembly or by the both the houses in case of a bicameral legislature is presented to the governor for his assent .There are four alternatives before the governor
1.he may give his assent to the bill
4.he may reserve the bill for the consideration of the president .
if the governor gives his assent to the bill the bill becomes an Act and is placed on the statue book .if ends and does not become an act .if the governor returns the bill for reconsideration and if the bill with or without amendment and presented to the governor for his assent the governor must give his assent to the bill .thus the governor enjoys only a suspensive veto .the position is same at the central level also . **Assent of the president**
when a bill is reserved by the governor of the consideration of the president the president may either give his assent to the bill or withhold his assent to the bill or return the bill for reconsideration of the house or houses of the state legislature . when a bill is so returned the house or houses have to reconsider it with in a period of six months . the bill is presented again to the presidential assent after it is passed by the house or houses with or without amendments . it is not mentioned in the constitution whether it is obligatory on the part of the president to give his assent to such a bill or not
