The Commission claims that the Court should declare that, by restricting, to groups whose members exercise a limited number of professions, the exemption from VAT for the supply by independent groups of persons carrying on an activity which is exempt from VAT, or in relation to which they are not taxable persons, of services to their members for the direct purposes of the exercise of that activity where those groups merely claim from their members exact reimbursement of their share of the joint expenses, Germany has failed to fulfil its obligations under Article 132(1)(f) of the VAT directive.
