Social security – Disability living allowance. The Supreme Court referred to the European Court of Justice questions arising from the issue of whether the United Kingdom was precluded, by Council Regulation (EC) no 1408/71 (on the application of social security schemes to employed persons, self-employed persons and members of their families moving within the Community) from imposing a requirement of residence in Great Britain as a condition of entitlement to disability living allowance and thus depriving a claimant who had gone to live in another Member State of that benefit.
