The extension of the six month deadline is not possible even in cases when foreign right holders fail to meet the deadline. In this case the presumption of law is rebutted. This, however, does not affect the rights of the foreign right holder, because provisional measures could be granted by the court under the general rules of the Code of Civil Procedure (Article 156). In such procedure the court is entitled to examine whether the ordering of the provisional measure is, inter alia, necessary to protect the petitioner's rights deserving special appreciation.
