General File is the first time the full Legislature has the opportunity to debate and vote on bills. At this stage, senators consider amendments, which may be proposed by committees and by individual senators. Many people consider General File to be the most crucial stage of the legislative process because it is where most compromises are reached. It takes a majority vote of the Legislature (25 votes) to adopt amendments or move a bill from General File to the next stage of consideration.
