Legislatures may give bills numbers as they progress.
Australia Bills are not given numbers in Australia and are typically cited by their
short titles. They are only given an act number upon
royal assent.
Brazil In Brazil, bills originating in both the
Senate and the
Chamber of Deputies are numbered sequentially, prefixed with "PL" () and optionally suffixed with the year they were proposed, separated by a slash, as in PL 1234/1988. Until 2019, each house used a different numbering and naming system, but the system was unified by a 2018 joint act by the secretaries of both houses. Before the 2019 unification, the Senate numbered bills starting at the beginning of each year, while the lower house numbered bills starting at the beginning of each legislature. This meant that bills sent from one house to another could adopt two or more different names.
Canada In the
House of Commons of Canada, the
pro forma bill is numbered C-1, Government Bills are numbered C-2 to C-200, numbered sequentially from the start of each
parliamentary session, and
Private member's bills are numbered C-201 to C-1000, numbered sequentially from the start of each Parliament. The numbering system is identical in the
Senate of Canada, except that bills first introduced in the Senate of Canada begin with "S" instead of "C".
Ireland In the Irish
Oireachtas, bills are numbered sequentially from the start of each calendar year. Bills originating in the
Dáil and
Seanad share a common sequence. There are separate sequences for public and private bills, the latter prefixed with "P". Although
acts to amend the constitution are outside the annual sequence used for other public acts,
bills to amend the constitution are within the annual sequence of public bills.
Philippines In the Philippines, all bills passed into law, regardless of whether they were introduced in the
House of Representatives or the
Senate, are numbered sequentially beginning with the first Republic Act that became law on July 15, 1946. There have been 11,646 Republic Acts as of January 21, 2022. All laws passed by Congress, once given presidential assent, become law and are given a sequential number and are prefixed with "Republic Act" or "R.A." for short. They are also given a secondary sequential number by the chamber they are introduced in. Aforementioned numberings restart every three years after the formation of a new Congress.
United Kingdom In the United Kingdom, for example, the
Coroners and Justice Act in 2009 started as Bill 9 in the House of Commons. Then it became Bill 72 on consideration by a
public bill committee; after that it became House of Lords Bill 33. Then it became House of Lords Bill 77, returned to the House of Commons as Bill 160, before finally being passed as Act 29. Parliament recommences numbering from one at the beginning of each session. This means that two different bills may have the same number. Sessions of parliament usually last a year. They begin with the
State Opening of Parliament, and end with
prorogation.
United States In the United States, all bills originating in the
House of Representatives are numbered sequentially and prefixed with "H.R." and all bills originating from the
Senate begin with an "S.". Every two years, at the start of odd-numbered years, the
Congress recommences numbering from 1, though for bills the House has an order reserving the first 20 bill numbers and the Senate has similar measures for the first 10 bills. Joint resolutions also have the same effect as bills, and are titled as "H. J. Res." or "S. J. Res." depending on whether they originated in the House or Senate, respectively. This means that two different bills can have the same number. Each two-year span is called a
congress, tracking the terms of Representatives elected in the nationwide biennial House of Representatives elections, and each congress is divided into year-long periods called
sessions. ==See also==
