Erskine May is the authoritative book on parliamentary law and practice. It’s a description of how procedure in the House of Commons and House of Lords has evolved and the conventions that apply, rather than a set of rules.
Erskine May is currently available on Parliament’s intranet. The new edition, which is due to be published in 2019, will be publicly available on Parliament’s website. You can also buy a hard copy or borrow one from the House of Commons Library.
The first edition was published in the mid-nineteenth century and new editions are published approximately every six or seven years.
Its full title is A treatise on the law, privileges, proceedings and usage of Parliament but it’s referred to as Erskine May after its original author Thomas Erskine May.
