IPEX , the InterParliamentary EU information eXchange , is a platform for the exchange of information between EU national parliaments and the European Parliament concerning issues related to the European Union , especially in light of the provisions of the Treaty of Lisbon .  The Treaty of Lisbon explicitly sets out the role of the national parliaments in the Protocol on the role of national parliaments in the European Union and the Protocol on the Application of the Principles of Subsidiarity and Proportionality .
History and Role
IPEX came out as a result of a recommendation made by the Conference of the Speakers of the European Union Parliaments  in Rome in 2000. In Accordance with the Guidelines for Interparliamentary Cooperation , agreed in The Hague in 2004, the official launch of the website took place in June 2006 during the EU Speakers Conference in Copenhagen.  The website was later redesigned, launching its new format in 2011. 
IPEX aims to support: the Speakers Conference; the Conference of Parliaments of the European Union ( COSAC ); meetings of the specialized committees of the National Parliaments and the European Parliament; interparliamentary meetings; and the liaison offices of the national parliaments in Brussels. IPEX is thus one of the major pillars of interparliamentary communication on European affairs, drawing together information from each of the national parliaments across the EU.
IPEX is intended to enable the national parliaments of EU Member States to cooperate more closely and coordinate their approaches to European affairs. In this context, IPEX offers multilingual navigation and publishes fundamental texts and opinions of the national parliaments in English, French and other EU languages.
IPEX receives contributions from all national Parliaments of the Member States of the European Union, the national parliaments of the European Parliament and the candidates of the European Parliament. Interservice interparliamentary cooperation, IPEX is open to COSAC and the European Center for Parliamentary Research and Documentation (ECPRD) .
Organization of IPEX
According to the IPEX Guidelines , the IPEX Board is responsible for decisions regarding the development of IPEX. The Board is appointed by the Secretaries General of the National Parliaments and the European Parliament on behalf of their Speakers.
IPEX is managed by the Central Support, the permanent IPEX information officer and a network of national IPEX Correspondents.
