Article 1
The High Contracting Parties agree to take all measures to discover, prosecute and punish any person engaged in committing any of the following offences, and accordingly agree that it shall be a punishable offence:
(1) for purposes of or by way of trade or for distribution or public exhibition to make or produce or have in possession obscene writings, drawings, prints, paintings, printed matter, pictures, posters, emblems, photographs, cinematograph films or any other obscene objects;
(2) for the purposes abovementioned, to import, convey or export or cause to be imported, conveyed or exported any of the said obscene matters or things, or in any manner whatsoever to put them into circulation;
(3) to carry on or take part in a business, whether public or private, concerned with any of the said obscene matters or things, or to deal in the said matters or things in any manner whatsoever, or to distribute them or to exhibit them publicly or to make a business of lending them;
(4) to advertise or make known by any means whatsoever, in view of assisting in the said punishable circulation or traffic, that a person is engaged in any of the above punishable acts, or to advertise or to make known how or from whom the said obscene matters or things can be procured either directly or indirectly.
Article 2
Persons who have committed an offence falling under Article 1 shall be amenable to the courts of the Contracting Party in whose territories the offence, or any of the constitutive elements of the offence, was committed. They shall also be amenable, when the laws of the country shall permit it, to the courts of the Contracting Party whose nationals they are, if they are found in its territories, even if the constitutive elements of the offence were committed outside such territories.
Each Contracting Party shall, however, have the right to apply the maxim non bis in idem in accordance with the rules laid down in its legislation.
Article 3
The transmission of rogatory commissions relating to offences falling under the present Convention shall be effected either:
(1) By direct communication between the judicial authorities; or
(2) Through the diplomatic or consular representative of the country making the request in the country to which the request is made; this representative shall send the rogatory commission direct to the competent judicial authority or to the authority appointed by the Government of the country to which the request is made, and shall receive direct from such authority the papers showing the execution of the rogatory commission.
In each of the above cases a copy of the rogatory commission shall always be sent to the supreme authority of the country to which application is made.
(3) Or through diplomatic channels.
Each Contracting Party shall notify to each of the other Contracting Parties the method or methods of transmission mentioned above which it will recognise for rogatory commissions of such Party.
Any difficulties which may arise in connection with transmission by methods (1) and (2) of the present Article shall be settled through diplomatic channels.
Unless otherwise agreed, the rogatory commission shall be drawn up in the language of the authority to which request is made, or in a language agreed upon by the two countries concerned, or shall be accompanied by a translation in one of these two languages certified by a diplomatic or consular agent of the country making the request or certified on his oath by a translator of the country to which request is made.
Execution of rogatory commissions shall not be subject to payment of taxes or expenses of any nature whatsoever.
Nothing in this Article shall be construed as an undertaking on the part of the Contracting Parties to adopt in their courts of law any form or methods of proof contrary to their laws.
Article 4
Those of the Contracting Parties whose legislation is not at present adequate to give effect to the present Convention undertake to take, or to propose to their respective legislatures, the measures necessary for this purpose.
Article 5
The Contracting Parties whose legislation is not at present sufficient for the purpose agree to make provision for the searching of any premises where there is reason to believe that the obscene matters or things mentioned in Article 1 or any thereof are being made or deposited for any of the purposes specified in the said Article, or in violation of its provisions, and for their seizure, detention and destruction.
Article 6
The Contracting Parties agree that, in case of any violation of the provisions of Article 1 on the territory of one of the Contracting Parties where it appears that the matter or thing in respect of which the violation of such Article has occurred was produced in or imported from the territory of any other of the Contracting Parties, the authority designated in pursuance of the Agreement of 4 May 1910 of such Contracting Party shall immediately render to the corresponding authority of the other Contracting Party, from whose country such matter or thing is believed to have come or in which it is believed to have been produced, full information so as to enable such authority to adopt such measures as shall appear to be suitable.
Article 7
The present Convention, of which the French and English texts are authoritative, shall bear this day's date, and shall be open for signature until 31 March 1924 by any State represented at the Conference, by any Member of the League of Nations, and by any State to which the Council of the League of Nations shall have communicated a copy of the Convention for this purpose.

In compliance with the provisions of Article 18 of the Covenant of the League of Nations, the Secretary-General will register the present Convention upon the day of its coming into force.

Adhesion shall be effected by an instrument communicated to the Secretary-General of the League of Nations to be deposited in the archives of the Secretariat.[2] The Secretary-General shall at once notify such deposit to all Members of the League of Nations signatories of the Convention and to other signatory States.
Article 10
Ratification of or adhesion to the present Convention shall ipso facto, and without special notification, involve concomitant and full acceptance of the Agreement of 4 May 1910, which shall come into force on the same date as the Convention itself in the whole of the territory of the ratifying or adhering Member of the League or State.
Article 4 of the abovementioned Agreement of 4 May 1910 shall not, however, be invalidated by the preceding provision, but shall remain applicable should any State prefer to adhere to that Agreement only.

The Secretary-General of the League of Nations shall notify the receipt of any such denunciation to all Members of the League of Nations signatories of or adherents to the Convention and to other signatory or adherent States.
Denunciation of the present Convention shall not, ipso facto, involve the concomitant denunciation of the Agreement of 4 May 1910 unless this is expressly stated in the instrument of notification.
Article 13
Any Member of the League of Nations or State signing or adhering to the present Convention may declare that its signature or adhesion does not include any or all of its colonies, overseas possessions, protectorates or territories under its sovereignty or authority, and may subsequently adhere separately on behalf of any such colony, overseas possession, protectorate or territory so excluded in its declaration.
Denunciation may also be made separately in respect of any such colony, overseas possession, protectorate or territory under its sovereignty or authority, and the provisions of Article 12 shall apply to any such denunciation.
Article 14
A special record shall be kept by the Secretary-General of the League of Nations, showing which of the parties have signed, ratified, adhered to or denounced the present Convention. This record shall be open at all times to any of the Members of the League of Nations or any State which has signed or adhered to the Convention. It shall be published as often as possible.
Article 15
Disputes between the Parties relating to the interpretation or application of this Convention shall, if they cannot be settled by direct negotiation, be referred for decision to the Permanent Court of International Justice. In case either or both of the Parties to such a dispute should not be Parties to the Protocol of Signature of the Permanent Court of International Justice, the dispute shall be referred, at the choice of the Parties, either to the Permanent Court of International Justice or to arbitration.
Article 16
Upon a request for a revision of the present Convention by five of the signatory or adherent Parties to the Convention, the Council of the League of Nations shall call a conference for that purpose.
