Colin Yeo, a UK immigration barrister, talks more about Case C-423/12 Flora May Reyes v. Migrationsverket here. This extract from Colin Yeo's blog post is particularly interesting:
I could be wrong but the case law seems to be saying that you only have to show evidence of past remittances to prove 'real dependency'.The Court noted that dependency has to be ‘real’ (the case of Jia [2007] EUECJ C-1/05). The court however emphasised that:
there is no need to determine the reasons for that dependence or therefore for the recourse to that support (para 23)
and
The fact that, in circumstances such as those in question in the main proceedings, a Union citizen regularly, for a significant period, pays a sum of money to that descendant, necessary in order for him to support himself in the State of origin, is such as to show that the descendant is in a real situation of dependence vis-à-vis that citizen (para 24)
Here is some more analysis of Case C-423/12. An extract from the analysis about the judgment of the case:
It looks like it's particuarly good news for dependants of working age - they can prove dependency simply by receiving regular remittances from their EU family member. Dependants also do not have to prove that they can't find work or can't get social security to be able to claim dependency. They also do not have to justify their reasons for why they are dependent on their EU family member.The Judgment
The CJEU echoed Case C-1/05 Jia in its determination that the existence of a situation of real dependence must be established, that this is a factual situation, and that it must exist in the State of origin (paras 20-22). The Court found that there was no requirement for a national court to consider the reasons for the dependence upon a Union citizen, in order to follow the principle that the Citizens’ Directive should be broadly construed. As long as a Union citizen has regularly given support over a significant period to the descendant claiming to be a dependent family member in order for the latter to support themselves in their State of origin, that descendant is shown to be in a situation of real dependence. There is no additional requirement for the descendant to establish that he/she has tried without success to find work or obtain subsistence support from the authorities of the State of origin/elsewhere in order to support him/herself- such a requirement would be likely to “deprive Articles 2(2)(c) and 7 of Directive 2004/38 of their proper effect” (para 26).
