The provisions of the TFEU relating to freedom of establishment preclude, in circumstances, such as those in the main proceedings, where the trustees, under national law, are treated as a single and continuing body of persons, distinct from the persons who may from time to time be the trustees, legislation of a Member State, such as that at issue in the main proceedings, which provides for the taxation of unrealised gains in value of assets held in trust when the majority of the trustees transfer their residence to another Member State, but fails to permit payment of the tax payable to be deferred.
