Artikel 138

1. Subject to the exceptions provided for in paragraphs 2 and 5, the following procedures shall govern the submission of proposals of all kinds to Congress by member countries:
1.1 proposals which reach the International Bureau at least four months before the date fixed for Congress shall be accepted;
1.2 no drafting proposal shall be accepted during the period of four months preceding the date fixed for Congress;
1.3 proposals of substance which reach the International Bureau in the interval between four and three months before the date fixed for Congress shall not be accepted unless they are supported by at least two member countries;
1.4 proposals of substance which reach the International Bureau in the interval between three and two months before the date fixed for Congress shall not be accepted unless they are supported by at least eight member countries; proposals which arrive after that time shall no longer be accepted;
1.5 declarations of support must reach the International Bureau within the same period of time as the proposal to which they refer.
2. Proposals concerning the Constitution or the General Regulations shall reach the International Bureau not later than four months before the opening of Congress; any received after that date but before the opening of Congress shall not be considered unless Congress so decides by a majority of two thirds of the member countries represented at Congress and unless the conditions laid down in paragraph 1 are fulfilled.
3. Every proposal must, as a rule, have only one aim and contain only the changes justified by that aim. Similarly, each proposal liable to lead to significant costs for the Union shall be accompanied by an indication of its financial impact, prepared by the member country submitting the proposal, in consultation with the International Bureau, so that the financial resources needed for its implementation can be determined.
4. Drafting proposals shall be headed “Drafting proposal” by the member countries which submit them and shall be published by the International Bureau under a number followed by the letter R. Proposals which do not bear this indication but which, in the opinion of the International Bureau, deal only with drafting points shall be published with an appropriate annotation; the International Bureau shall draw up a list of these proposals for Congress.
5. The procedure prescribed in paragraphs 1 and 4 shall apply neither to proposals concerning the Rules of Procedure of Congresses, nor to proposals submitted by the Council of Administration or the Postal Operations Council.
