The European Parliament or the Council may request the opinion of the Commission throughout the procedure, which the Commission may also deliver on its own initiative.
Féadfaidh Parlaimint na hEorpa nó an Chomhairle a thuairim a iarraidh ar an gCoimisiún i gcaitheamh an nós imeachta, agus féadfaidh an Coimisiún tuairim a thabhairt ar a thionscnamh féin freisin.
