Artikel 7

The Contracting States undertake to take the most appropriate measures by their national legislation and administration both to prevent the arbitrary or unjust application of their laws and regulations with regard to Customs and other similar matters, and to ensure redress by administrative, judicial or arbitral procedure for those who may have been prejudiced by such abuses.
All such measures which are at present in force or which may be taken hereafter shall be published in the manner provided by Articles 4 and 5.
