Article 4
1. Any Member State may withdraw a navigability licence which it has issued. 2. Any Member State may interrupt the passage of a vessel, where the vessel is found on inspection to be in a condition which constitutes a danger to the surroundings, until the defects have been corrected. That Member State may also do so where the vessel or its equipment is found on inspection not to satisfy the requirements set out in the navigability licence or in the other documents referred to in Article 3 as the case may be. 3. A Member State which has interrupted the passage of a vessel, or which has indicated its intention to do so if the defects are not corrected, shall inform the competent authorities of the Member State where the navigability licence or the other documents referred to in Article 3 were issued of the reasons for the decision it has taken or it intends to take. 4. All decisions to interrupt the passage of a vessel taken pursuant to measures adopted in implementation of this Directive shall state in detail the reasons on which they are based. A decision shall be notified to the party concerned, who shall at the same time be informed of the remedies available to him under the laws in force in the Member States and of the time limits allowed for the pursuit of such remedies.
