Numbering of Parliamentary Papers

  • Parliamentary session

In the UK, the Fixed-term Parliaments Act 2011 sets the interval between general elections at five years. Each Parliament is usually divided into five parliamentary years called ‘sessions', beginning and ending in the spring.  Note before 2010 the sessions generally ran from autumn to autumn.

  • Types of parliamentary papers

House of Commons paper: HC Paper
House of Commons bill: Bill
House of Lords paper: HL Paper
House of Lords bill: HL Bill
Command paper

  • Numbering

Numbering for HC and HL papers and bills begins at ‘1’ at the beginning of each parliamentary session.  

Command paper numbering runs from 1 to nearly 10, 000 across many parliamentary sessions. Command papers with the same numbering are differentiated by the letter prefix.
