Artikel 39

1. In addition to the power given in the preceding article, a Party, in acceding to the present General Act, may make his acceptance conditional upon the reservations exhaustively enumerated in the following paragraph. These reservations must be indicated at the time of accession.
2. These reservations may be such as to exclude from the procedure described in the present Act:
(a) Disputes arising out of facts prior to the accession either of the Party making the reservation or of any other Party with whom the said Party may have a dispute;
(b) Disputes concerning questions which by international law are solely within the domestic jurisdiction of States;
(c) Disputes concerning particular cases or clearly specified subject-matters, such as territorial status, or disputes falling within clearly defined categories.
3. If one of the parties to a dispute has made a reservation, the other parties may enforce the same reservation in regard to that party.
4. In the case of Parties who have acceded to the provisions of the present General Act relating to judicial settlement or to arbitration, such reservations as they may have made shall, unless otherwise expressly stated, be deemed not to apply to the procedure of conciliation.
