another, as well as lateral canals and channels constructed either to duplicate or to improve naturally navigable sections of the specified river system or to connect two naturally navigable sections of the same river.
Any part of the above-mentioned river system which is not included in the general definition may be declared international by an agreement between the riparian States.
Article 276.
On the waterways declared to be international in the preceding Article, the nationals, property and flags of all Powers shall be treated on a footing of perfect equality, no distinction being made, to the detriment of the nationals, property or flag of any Power, between them and the nationals, property or flag of the riparian State itself or of the most-favoured nation.
Article 277.
Hungarian vessels shall not be entitled to carry passengers or goods by regular services between the ports of any Allied or Associated Power without special authority from such Power.
Article 278.
Where such charges are not precluded by any existing convention, charges varying on different sections of a river may be levied on vessels using the navigable channels or their approaches, provided that they are intended solely to cover equitably the cost of maintaining in a navigable condition, or of improving, the river and its approaches, or to meet expenditure incurred in the interests of navigation. The schedule of such charges shall be calculated on the basis of such expenditure and shall be posted up in the ports. These charges shall be levied in such a manner as to render any detailed examination of cargoes unnecessary, except in cases of suspected fraud or contravention.
Article 279.
The transit of vessels, passengers and goods on these waterways shall be effected in accordance with the general conditions prescribed for transit in Section I above.
When the two banks of an international river are within the same State goods in transit may be placed under seal or in the custody of customs agents. When the river forms a frontier goods and passengers in transit shall be exempt from all customs formalities; the loading and unloading of goods, and the embarkation and disembarkation of passengers, shall only take place in the ports specified by the riparian State.
Article 280.
No dues of any kind other than those provided for in this Part shall be levied along the course or at the mouth of these waterways.
This provision shall not prevent the fixing by the riparian States of customs, local octroi or consumption duties, or the creation of reasonable and uniform charges levied in the ports, in accordance with public tariffs, for the use of cranes, elevators, quays, warehouses and other similar constructions.
Article 281.
In default of any special organisation for carrying out the works connected with the upkeep and improvement of the international portion of a navigable system, each riparian State shall be bound to take the necessary measures to remove any obstacle or danger to navigation and to ensure the maintenance of good conditions of navigation.
If a State neglects to comply with this obligation any riparian State, or any State represented on the International Commission, may appeal to the tribunal instituted for this purpose by the League of Nations.
Article 282.
The same procedure shall be followed in the case of a riparian State undertaking any works of a nature to impede navigation in the international section. The tribunal mentioned in the preceding Article shall be entitled to enforce the suspension or suppression of such works, making due allowance in its decisions for all rights in connection with irrigation, water-power, fisheries and other national interests, which, with the consent of all the riparian States or of all the States represented on the International Commission, shall be given priority over the requirements of navigation.
Appeal to the tribunal of the League of Nations does not require the suspension of the works.
