When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
This is the revised version from EUR-Lex dated 29/12/2006. There are no timeline of changes available for treaties, instead, previous dated versions from EUR-Lex (as pdf) can be accessed via the More Resources menu. This treaty was originally signed in Maastricht in 1992 (The Maastricht Treaty).
When enhanced cooperation is being established, it shall be open to all Member States. It shall also be open to them at any time, in accordance with Articles 27e and 40b of this Treaty and with Article 11a of the Treaty establishing the European Community, subject to compliance with the basic decision and with the decisions taken within that framework. The Commission and the Member States participating in enhanced cooperation shall ensure that as many Member States as possible are encouraged to take part.
