If measures taken in the circumstances referred to in Articles 346 and 347 have the effect of distorting the conditions of competition in the internal market, the Commission shall, together with the State concerned, examine how these measures can be adjusted to the rules laid down in the Treaties.

By way of derogation from the procedure laid down in Articles 258 and 259, the Commission or any Member State may bring the matter directly before the Court of Justice if it considers that another Member State is making improper use of the powers provided for in Articles 346 and 347. The Court of Justice shall give its ruling in camera.
