The adaptations made by virtue of paragraphs 2 and 3 of this article and imported without the authorization of the parties interested into a country where they are not lawful, may be seized there.

{Sidenote: Seizure to be made according to the laws of each country}

The seizure shall take place conformably to the domestic law of each State.

ARTICLE 17

{Sidenote: Each government to exercise supervision}

The provisions of the present Convention cannot in any way derogate from the right belonging to the Government of each country of the Union to permit, to control, or to prohibit, by measures of domestic legislation or police, the circulation, representation, or exhibition of any works or productions in regard to which the competent authority may find it necessary to exercise that right.

{Sidenote: Convention to apply to all works not in public domain}

The present Convention applies to all works which, at the moment of its coming into force, have not fallen into the public domain of their country of origin because of the expiration of the term of protection.

But if a work by reason of the expiration of the term of protection which was previously secured for it has fallen into the public domain of the country where protection is claimed, such work will not be protected anew.

{Sidenote: Special conventions and domestic legislation may govern}

This principle will be applied in accordance with the stipulations to that effect contained in the special Conventions either existing or to be concluded between countries of the Union, and in default of such stipulations, its application will be regulated by each country in its own case.

The preceding provisions apply equally in the case of new accessions to the Union and where the term of protection would be extended by the application of Article 7.

ARTICLE 19

{Sidenote: More extensive rights may be granted by domestic legislation}

The provisions of the present Convention do not prevent a claim for the application of more favorable provisions which may be enacted by the legislation of a country of the Union in favor of foreigners in general.

ARTICLE 20

{Sidenote: More extensive rights may be secured by special treaties}

The governments of the countries of the Union reserve the right to make between themselves special treaties, when these treaties would confer upon authors more extended rights than those accorded by the Union, or when they contain other stipulations not conflicting with the present Convention. The provisions of existing treaties which answer the aforesaid conditions remain in force.
