“Did HMRC and the First-tier Tribunal investigate sufficiently and explain adequately the basis for non-entitlement to child tax credit in that year[?] Being in work of itself is not a necessary condition for qualifying for child tax credit. As an Italian (i.e. EU) national it might provide a basis under the right to reside test for saying [the appellant] was not a qualifying person based on her being a “worker” (that is, in work) in 2013/2014. However given her evidence…..about having worked in the UK since 2011 and the school age of at least two of her children, did HMRC and the First-tier Tribunal look sufficiently at whether she could in 2013/2014 have had what is called a ‘derivative right to reside’ under article 10 of Regulation (EU) No. 492/2011 based on her work in 2011 (assuming it can be properly evidenced) and her children being in education? In other words, if the basis for the child tax credit decision was the right to reside test, ought HMRC and the First-tier Tribunal [to] not have addressed and explained why [the appellant] did not have a derivative right to reside under article 10 of Regulation (EU) No. 492/2011?”
