How The House Works (via Wikipedia):
Delegates submit bill proposals to the Office of Legislative Services or legislative staff counsel, who draft the bill. Once the bill draft is approved by the delegate, it is submitted for introduction. Bills then undergo committee review and three readings in the house of origin and then the other house of the state legislature.
An unusual feature of the West Virginia legislative process is that revenue bills can originate in either house. The state constitution also prohibits multiple subjects in a single bill.
If approved by both the West Virginia House of Delegates and the West Virginia Senate, bills are submitted to the governor, who may sign them into law or veto them. State legislators can override the governor’s veto of bills with a simple majority vote of both houses, unless the bill is a revenue bill, in which case two-thirds of the members elected to each house are required to override the governor’s veto or line-item veto.
