“when a Community national who availed himself or herself of those (Treaty) rights returns to his or her country of origin, his or her spouse must enjoy at least the same rights of entry and residence as would be granted to him or her under Community law if his or her spouse chose to enter and reside in another Member State.”
“A national of a Member State could be deterred from leaving that Member State in order to pursue gainful employment in the territory of another Member State if he does not have the certainty of being able to return to his Member State of origin, irrespective of whether he is going to engage in economic activity in the latter State. That deterrent effect would also derive simply from the prospect, for that same national, of not being able, on returning to his Member State of origin, to continue living together with close relatives, a way of life which may have come into being in the host Member State as a result of marriage or family reunification. Barriers to family reunification are therefore liable to undermine the right to free movement which the nationals of the Member States have under Community law, as the right of a Community worker to return to the Member State of which he is a national cannot be considered to be a purely internal matter.”
