‘A couple of years ago a lot of lawyers practising in housing, immigration and welfare benefits got very excited by the case of Ruiz Zambrano (European citizenship) [2011] EUECJ C-34/09. The reason for this excitement was that the ECJ said that art.20, of the Treaty, required member states to grant a right of residence to a third country national, who was the primary carer of an EU national, if a refusal to would result in the EU national being forced to leave the EU..More excitingly, this applied to EU nationals who had not left their member state, i.e. it would apply to the parents of British nationals.’
