The European Commission (EC) is the executive body of the European Union responsible for proposing legislation, implementing decisions, upholding the Union's treaties and day-to-day running of the EU. Commissioners swear an oath at the European Court of Justice in Luxembourg, pledging to respect the EU Treaties and to be completely independent in carrying out their duties during their mandate.
The Commission operates as a cabinet government, with 28 members of the Commission (informally known as "commissioners").
