PMB

Any MP Can Introduce a Law. Almost None of Them Pass. Here's the Lottery That Decides Which Ones Even Get a Chance.

Legislation in the House of Commons comes in two streams. Government bills carry the government's agenda, get priority access to House time, and are backed by the whip — most pass. Private members' bills (PMBs) are introduced by MPs who are not ministers (backbenchers and opposition members) and travel a far harder road. Which MPs even get a chance is set by a random draw at the start of a Parliament that orders members on the "List for the Consideration of Private Members' Business"; only those near the top will realistically reach debate, since private members' business gets a limited slot (about one hour on most sitting days). A PMB that is reached gets two hours of second-reading debate spread across separate days, a committee stage, report stage, and third reading — each competing for scarce slots — and votes on PMBs are more often free (unwhipped) than government bills. The combination of the lottery, the time scarcity, the free-vote unpredictability, and the government's control of the broader calendar means the large majority of PMBs never become law. The ones that do tend to be narrowly scoped, broadly sympathetic, or quietly backed by the government; private members' bills cannot directly appropriate public money (a "royal recommendation" from the government is required for spending), which rules out an entire category. Despite the odds, PMBs are a real avenue: they put issues on the record, force recorded votes, and occasionally pass into law.
