What does the C1, C2, C3, etc., mean on the end of a bill number in bill history?
“C1” denotes a committee substitute, which is a substitute bill proposed by committee for a bill considered and amended by that committee. Each committee to which a bill is referred may adopt a committee substitute for that bill. If the previous committee of reference adopted a committee substitute for the bill, the next committee may adopt a committee substitute for that committee substitute. Occasionally, there will be a committee substitute for a committee substitute for a committee substitute for a committee substitute for a bill (C4). A committee substitute may also combine multiple Senate bills.
