The exception provided for in Article 1(2)(b) of Council Regulation No 44/2001 (EC) of 22 December 2000 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters must be interpreted as applying to a judgment of a court of Member State A regarding registration of ownership of shares in a company having its registered office in Member State A, according to which the transfer of those shares was to be regarded as invalid on the ground that the court of Member State A did not recognise the powers of a liquidator from a Member State B in the context of insolvency proceedings conducted and closed in Member State B.
