Roli kryesor i Komisionit është të propozojë dhe implementojë legjislacione dhe të mbikqyrë [[traktatet e BE]]-së, të cilat formojnë bazën ligjore të BE-së.
The Commission consists of 25 Commissioners, one from each member state of the EU, supported by an administrative body of several thousand European civil servants divided into departments called [[Directorate-General]]. The term "the Commission" is generally used to refer both to the administrative body in its entirety, and to the team of Commissioners who lead it.
Unlike the [[Council of the European Union]], the Commission is intended to be a body independent of member states. Commissioners are therefore not permitted to take instructions from the government of the country that appointed them, but are supposed to represent the interests of the citizens of the EU as a whole.
The Commission is headed by a [[President of the European Commission|President]] (currently [[José Manuel Durão Barroso]]). Its headquarters are located in [[Brussels]] and its [[working language]]s are [[English language|English]], [[French language|French]] and [[German language|German]].
