This is a very important decision of the Supreme Court concerning a challenge brought under Articles 8 and 12 ECHR, read alone and with Article 14, to the restriction of the individual element of child tax credit to an amount calculated by reference to two children. The Supreme Court rejected the challenges under Articles 8 and 12 and, of more relevance to this blog, rejected arguments about direct and indirect discrimination against children, though it accepted that there were prima facie cases of sex discrimination and of direct discrimination against children living in households with more than two children, as compared with children living in households with two or fewer children.
The challenge ultimately failed on justification grounds but the case, which has been cited extensively in virtually every Article 14 decision of the domestic courts since it was decided, is significant because the Court revisited the “manifestly without reasonable foundation” which had been the orthodox approach to Convention challenges to economic/ social policy in the domestic courts since at least 2012. The case was also significant in that it reimposed an orthodox approach to the treatment of unincorporated international obligations (here the Convention on the Rights of the Child) and included extensive consideration of the reliance which might be placed by the courts on Parliamentary debates and other Parliamentary material when considering whether primary legislation is compatible with Convention rights.
