Either an Assembly member or a Senator introduces the bill (The bill is given a number which is preceded by either AB (Assembly author) or SB (Senate author).
The bills begin in the house of origin and are heard by a policy committee (Some bills may get double referred. This means two separate policy committees will hear the bill.)
If the bill passes policy committee, it is referred to the Appropriations committee if it has fiscal impact. If no fiscal impact, it is referred directly to the floor of the house of origin.
Once the bill has passed all the committees, it is sent to the floor for vote by the whole membership of Assembly or Senate.
If it passes off the floor it is sent to the other side of the house. (All Assembly bills will be heard by Senators and Senate bills will be heard by Assembly members).
The bill will be heard by policy committees and if passed, referred to either the Appropriations committee or the floor.
If the bill is amended in the house of non-origin and is passed off the floor, the bill will have to go back to the house of origin for the amendments to be concurred.
Once the bill has passed both houses (and if applicable, amendments were concurred), it is sent to the Governor's office for his signature. It is then law and will become enforceable on January 1 of the following year (unless the bill has an urgency clause which would make the bill enforceable as soon as the Governor signs it).
