On 19 June 1990 the ECJ court (as "full court" of 11 justices) "en banc" gave its ruling, rephrasing the question posed as "whether a national court which, in a case before it concerning Community law, considers that the sole obstacle which precludes it from granting interim relief is a rule of national law, must disapply that rule". Following the Advocate-General's opinion, the ECJ held that a national court, in fact, has a duty to grant interim relief to safeguard alleged Community rights of individuals until the decision of the ECJ on the interpretation of Community law is available, and where a rule of national law would deny such relief, to set aside that rule. The basis of such a duty lies in the nature and object of directly effective Community law rights which are intended to be fully effective throughout the EU, and where, in order to safeguard such a right, it is necessary to grant interim measures, a national court must do so. This is especially true where a national court is awaiting a clarification or interpretation of the right claimed by the ECJ.
