European Union – Freedom of movement. The European Court of Justice Union ruled that art 41(1) of the Additional Protocol concluded, approved and confirmed on behalf of the Community by Council Regulation (EEC) No 2760/72 and annexed to the Association Agreement had to be interpreted as meaning that the 'standstill' clause set out in that provision precluded a measure of national law, introduced after the entry into force of that additional protocol in the member state concerned, which imposed on spouses of Turkish nationals residing in that member state, who wished to enter the territory of that state for the purposes of family reunification, the condition that they demonstrate beforehand that they had acquired basic knowledge of the official language of that member state.
