“15.— Permanent right of residence (1) The following persons shall acquire the right to reside in the United Kingdom permanently— (a) an EEA national who has resided in the United Kingdom in accordance with these Regulations for a continuous period of five years; (b) a family member of an EEA national who is not himself an EEA national but who has resided in the United Kingdom with the EEA national in accordance with these Regulations for a continuous period of five years; . . . ”
“58. Inasmuch as periods of residence of a Union citizen in a host Member State which were completed on the basis solely of a residence permit validly issued under Directive 68/360, but without the conditions governing entitlement to any right of residence having been satisfied, cannot be regarded as having been completed legally for the purposes of the acquisition of the right of permanent residence under art.16(1) of Directive 2004/38, the question then arises as to what the effect is on that acquisition of such a period of residence which occurred before April 30, 2006 and after a period of five years’ continuous legal residence already completed prior to that date. 59. In that connection, it should be borne in mind, first of all, that the Court has already ruled that art.16(4) of Directive 2004/38 refers to loss of the right of permanent residence by reason of absences of more than two consecutive years from the host Member State and that such a measure may be justified because, after an absence of that duration, the link with the host Member State is loosened (see Lassal [2011] 1 C.M.L.R. 31 at [55]). 60. Next, the Court has also held that that provision falls to be applied independently of whether the periods of residence in question were completed before or after April 30, 2006, for the reason that, since residence periods of five years completed before that date must be taken into account for the purpose of acquisition of the right of permanent residence provided for in art.16(1) of Directive 2004/38, non-application of art.16(4) thereof to those periods would mean that the Member States would be required to grant that right of permanent residence even in cases of prolonged absences which call into question the link between the person concerned and the host Member State ( Lassal [2011] 1 C.M.L.R. 31 at [56]). 61. Finally, the Court has held that the application of art.16(4) of Directive 2004/38 to continuous periods of five years’ legal residence completed before April 30, 2006 implies, in particular, that absences from the host Member State of less than two consecutive years occurring after those periods but before that date are not such as to affect the link of integration of the Union citizen concerned and, accordingly, those absences are not such as to affect the acquisition of the right of permanent residence pursuant to art.16(1) of Directive 2004/38 ( Lassal [2011] 1 C.M.L.R. 31 at [57] and [58]). 62. Such reasoning must also be applied by analogy to periods of residence completed on the basis solely of a residence permit validly issued pursuant to Directive 68/360, without the conditions governing entitlement to any right of residence having been satisfied, which occurred before April 30, 2006 but after a continuous period of five years’ legal residence completed prior to that date. 63. Even though art.16(4) of Directive 2004/38 refers only to absences from the host Member State, the integration link between the person concerned and that Member State is also called into question in the case of a citizen who, while having resided legally for a continuous period of five years, then decides to remain in that Member State without having a right of residence. 64. In that regard, it should be noted, as the A.G. has stated in points AG106 and AG107 of her Opinion, that the integration objective which lies behind the acquisition of the right of permanent residence laid down in art.16(1) of Directive 2004/38 is based not only on territorial and time factors but also on qualitative elements, relating to the level of integration in the host Member State. 65. As the situations are comparable, it follows that the rule laid down in art.16(4) of Directive 2004/38 must also be applied by analogy to periods in the host Member State completed on the basis solely of a residence permit validly issued under Directive 68/360, without the conditions governing entitlement to a right of residence of any kind having been satisfied, which occurred before April 30, 2006 and after a continuous period of five years’ legal residence completed prior to that date.”
