Competence in scrutinising and amending legislation is shared between the Council of the European Union and the European Parliament, while executive tasks are performed by the European Commission and in a limited capacity by the European Council (not to be confused with the aforementioned Council of the European Union).
Wewenang untuk meneliti dan mengamendemen legislasi dibagi antara Parlemen Eropa dan Dewan Uni Eropa, sementara tugas eksekutif ditangani oleh Komisi Eropa dan, secara terbatas, oleh Dewan Eropa (tidak boleh disamadengankan dengan Dewan Uni Eropa yang disebut terlebih dahulu).
