Committees in charge of scrutinising subsidiarity   
There is no specific committee in charge of scrutinising subsidiarity.

Staff in charge of subsidiarity scrutiny  
One staff member is in charge of European Affairs.

Subsidiarity check  
Nature (selective/systematic): The Parliament has never performed subsidiarity checks, except on three occasions (in the area of environment and employment) in 2007 and 2008, at the initiative of the Committee of the Regions.

Procedure: Due to the tight deadlines involved in conducting a subsidiarity scrutiny, the European legislative documents are transmitted electronically directly after reception of the French and Dutch versions. This is disseminated by the Parliament administration to all the members of the relevant committees. The information transfer is further guaranteed by the availability of online documents and a bi-monthly update email. This information contains all of the documents sent out by the European institutions including non-legislative information.
The President of each committee acts as a promoter of this information.
The Parliament can ask for the collaboration and expertise of the government and of the regional administration when it has to formulate such a proposal.
The President will, either on his or her own initiative or by request of a third of the members of the committee, send a proposal on the members' point of view, in connection with the European legislative document pertaining to the principle of subsidiarity.
The opinion of subsidiarity is adopted in the form of a motion for a resolution by the committee. It is then passed on to the plenary session for its adoption and then transmitted to the Senate, and addressed to the European Commission.

Cooperation/coordination at the regional level  
See the answer to the previous point.

Cooperation/coordinationat the central level 
In 2008, the Belgian parliamentary assemblies (at federal, regional and community level) drafted an inter-parliamentary cooperation agreement organising the participation of the regional and community parliaments in the application of the subsidiarity scrutiny mechanism. This agreement has been blocked because of persisting legal and political difficulties, and accordingly, has not yet entered into force. However, the relevant institutions generally apply it de facto in concrete situations. The regional parliaments automatically receive all legislative proposals and consultation documents of the European Commission through the Senate, with no selection or priority-setting. Each parliament can separately and autonomously examine whether the legislative proposal respects the principle of subsidiarity. A system of vote distribution is established, i.e., the two Belgian subsidiarity votes are divided between the federal and the regional levels. There is no need for a consensus on a 'level basis' to make use of the subsidiarity vote. As soon as one chamber (at the federal level) considers a legislative proposal to be in breach of the subsidiarity principle, at least one subsidiarity vote is ‘activated’. Furthermore, if (at least) one parliament at the regional/community level has the same opinion, the second subsidiarity vote is also used. All reasoned opinions of the seven parliaments, together with the subsidiarity votes, are sent to the European Commission on behalf of the Belgian parliamentary system, making it clear which opinion has been given by which parliament. For the so-called exclusive legislative proposals (concerning exclusively federal or regional/community competences), the competent level controls the two Belgian subsidiarity votes. Once again, no consensus is needed; it is enough for two regional/community parliaments with a different linguistic status (e.g. the Flemish Parliament (Dutch speaking) and the Walloon Parliament (French speaking)) to consider that a proposal infringes the principle of subsidiarity, to trigger the two Belgian subsidiarity votes in the Early Warning System.
