With a view to providing this clarification, the Constitution defines the Union's competences, dividing them into three categories, each with a different legal status and each implying a different degree of Union intervention: the Union's exclusive competences; the competences it shares with the Member States; and action to support or complement action by the Member States.
Ar nodomu sniegt šo skaidrojumu, Konstitūcija definē Savienības kompetences, sadalot tās trīs kategorijās, katrai no tām ir cits juridiskais statuss un cita Kopienas iejaukšanās pakāpe – Savienības īpašās kompetences, kompetences, kuras tā dala ar dalībvalstīm, un darbības, kas domātas dalībvalstu atbalstam.
