Question referred

Does the principle of EU law based on a single social security scheme applicable to workers, whether employed or self-employed, active or retired, preclude a Member State of residence from requiring, as in the present case, a retired official of the European Commission, who pursues an activity as a self-employed person, to be subject to its social security scheme and the payment of purely ‘solidarity’ social security contributions, where the retired official is subject to the compulsory social security scheme of the European Union and does not derive any benefits, be they contributory or non-contributory, from the national scheme to which he or she is subject by force?
