RULES OF CONDUCT FOR THE 
UNDERSTANDING ON RULES AND PROCEDURES 
GOVERNING THE SETTLEMENT OF DISPUTES 
 
 
 I. Preamble  
 
 Members, 
 
 Recalling  that on 15 April 1994 in Marrakesh, Ministers welcomed the stronger and clearer 
legal framework they had adopted for the conduct of  international trade, including a more effective 
and reliable dispute settlement mechanism;  
 Recognizing  the importance of full adherence to th e Understanding on Rules and Procedures 
Governing the Settlement of Disputes ("DSU") and the principles for the management of disputes applied under Articles XXII and XXIII of GATT 1947, as further elaborated and modified by the 
DSU;   Affirming  that the operation of the DSU would be strengthened by rules of conduct designed 
to maintain the integrity, impartiality and conf identiality of proceedings conducted under the DSU 
thereby enhancing confidence in the new dispute settlement mechanism; 
  Hereby establish the following Rules of Conduct.  
 
 II. Governing Principle  
 
1. Each person covered by these Rules (as defi ned in paragraph 1 of Section IV below and 
hereinafter called "covered person") sh all be independent and impartial, shall avoid direct or indirect 
conflicts of interest and shall respect the confid entiality of proceedings of bodies pursuant to the 
dispute settlement mechanism, so that through th e observance of such standards of conduct the 
integrity and impartiality of that mechanism are pr eserved.  These Rules shall in no way modify the 
rights and obligations of Members under the DSU nor the rules and procedures therein.    III. Observance of the Governing Principle  
 
1. To ensure the observance of the Governing Principle of these Rules, each covered person is 
expected (1) to adhere strictly to the provisions  of the DSU;  (2) to disclose the existence or 
development of any interest, relationship or matter th at that person could reasonably be expected to 
know and that is likely to affect, or give rise to  justifiable doubts as to, that person's independence or 
impartiality; and (3) to take due care in the perfo rmance of their duties to fulfil these expectations, 
including through avoidance of any direct or indirect  conflicts of interest in  respect of the subject 
matter of the proceedings.  2. Pursuant to the Governing Principle, each cove red person, shall be inde pendent and impartial, 
and shall maintain confidentiality.  Moreover, such  persons shall consider only issues raised in, and 
necessary to fulfil their responsibilities within, th e dispute settlement proceeding and shall not 
delegate this responsibility to any other person.  Such person shall not incur any obligation or accept 
any benefit that would in anyway interfere with, or  which could give rise to, justifiable doubts as to 
the proper performance of that person's dispute settlement duties. WT/AB/WP/4 
Page 17 
 
 
 IV. Scope  
 
1. These Rules shall apply, as specified in the text, to each person serving:  (a) on a panel;  
(b) on the Standing Appellate Body;  (c) as an arb itrator pursuant to the provisions mentioned in 
Annex "1a";  or (d) as an expert participating in  the dispute settlement mechanism pursuant to the 
provisions mentioned in Annex "1b".  These Rules sha ll also apply, as specified in this text and the 
relevant provisions of the Staff Regulations, to those members of the Secretariat called upon to assist 
the panel in accordance with Article 27.1 of the DSU or to assist in formal arbitration proceedings 
pursuant to Annex "1a"; to the Chairman of the Te xtiles Monitoring Body (hereinafter called "TMB")

recommendations, findings or observations pursuant to the WTO Agreement on Textiles and 
Clothing; and to Standing Appellate Body support st aff called upon to provide  the Standing Appellate 
Body with administrative or legal support in accord ance with Article 17.7 of the DSU (hereinafter 
"Member of the Secretariat or Standing Appellate Bo dy support staff"), reflecting their acceptance of 
established norms regulating the conduct of such persons as international civil servants and the 
Governing Principle of these Rules. 
 2. The application of these Rules shall not in an y way impede the Secretariat's discharge of its 
responsibility to continue to respond to Memb ers' requests for assistance and information. 
 3. These Rules shall apply to the members of th e TMB to the extent prescribed in Section V. 
 
 
 V. Textiles Monitoring Body  
 
1. Members of the TMB shall discharge their functions on an ad personam  basis, in accordance

 VI. Self-Disclosure Requirements by Covered Persons  
 
1. (a) Each person requested to serve on a pa nel, on the Standing Appellate Body, as an 
arbitrator, or as an expert shall, at the time of  the request, receive from the Secretariat these Rules, 
which include an Illustrative List (Annex 2) of examples of the matters subject to disclosure. 
 
 (b) Any member of the Secretariat describe d in paragraph IV:1, who may expect to be 
called upon to assist in a dispute, and Standing Appe llate Body support staff, shall be familiar with 
these Rules.  2. As set out in paragraph VI:4 below, all covered persons described  in paragraph VI.1(a) 
and VI.1(b) shall disclose any information that coul d reasonably be expected to be known to them at 
the time which, coming within the scope of the Gove rning Principle of these Rules, is likely to affect 
                                                     
 
1These working procedures, as adopted by the TMB on  26 July 1995 (G/TMB/R/1), currently include, 
inter alia , the following language in paragraph 1.4: "In discharging their functions in accordance with 
paragraph 1.1 above, the TMB members and alternates shall undertake not to solicit, accept or act upon 
instructions from governments, nor to be influenced by any other organisations or undue extraneous factors.  
They shall disclose to the Chairman any information that they may consider likely to impede their capacity to discharge their functions on an ad personam  basis.  Should serious doubts arise during the deliberations of the 
TMB regarding the ability of a TMB member to act on an ad personam  basis, they shall be communicated to the 
Chairman.  The Chairman shall deal with  the particular matter as necessary". WT/AB/WP/4 
Page 18  
 
or give rise to justifiable doubts as to their independence or impartiality.  These disclosures include the type of information described in  the Illustrative List, if relevant. 
 3. These disclosure requirements shall not exte nd to the identification of matters whose 
relevance to the issues to be considered in the pr oceedings would be insignificant.  They shall take 
into account the need to respect the personal privacy  of those to whom these Rules apply and shall not 
be so administratively burdensome as to make it impracticable for otherw ise qualified persons to 
serve on panels, the Standing Appellate Body , or in other dispute settlement roles. 
 4. (a) All panelists, arbitrators and experts, prior to confirmation of their appointment, shall 
complete the form at Annex 3 of these Rules.  Such  information would be disclosed to the Chair of 
the Dispute Settlement Body ("DSB") for cons ideration by the parties to the dispute. 
 
(b) (i) Persons serving on the Standing Appellate Body who, through rotation, are 
selected to hear the appeal of a particular panel case, shall review the factual 
portion of the Panel report and comple te the form at Annex 3.  Such 
information would be disclosed to th e Standing Appellate Body for its 
consideration whether the member concer ned should hear a particular appeal. 
 
(ii) Standing Appellate Body support sta ff shall disclose any relevant matter to 
the Standing Appellate Body, for its consideration in deciding on the 
assignment of staff to assist in a particular appeal. 
 
(c) When considered to assist in a dispute, members of the Secretariat shall disclose to 
the Director-General of the WTO the information required under paragraph VI:2 of these Rules and 
any other relevant information required under th e Staff Regulations, including the information 
described in the footnote.
** 
 5. During a dispute, each covered person shall al so disclose any new information relevant to 
paragraph VI:2 above at the earliest  time they become aware of it. 
 6. The Chair of the DSB, the Secretariat, parties to the dispute, and other individuals involved in 
the dispute settlement mechanism shall maintain the confidentiality of any information revealed 
through this disclosure process, even after the pane l process and its enforcement procedures, if any, 
are completed.   
                                                     
 
**Pending adoption of the Staff Regulations, members of the Secretariat shall make disclosures to the 
Director-General in accordance with the following draft provision to be included in the Staff Regulations: 
"When paragraph VI:4(c) of the Rules of Conduct for the DSU is applicable, members of the 
Secretariat would disclose to the Dir ector-General of the WTO the information required in paragraph VI:2 of 
those Rules, as well as any information regarding thei r participation in earlier formal consideration of the 
specific measure at issue in a dispute under any provisions of the WTO Agreement, including through formal 
legal advice under Article 27.2 of the DSU, as well as an y involvement with the disput e as an official of a WTO 
Member government or otherwise professionally , before having joined the Secretariat. 
The Director-General shall consider  any such disclosures in deciding on the assignment of members of 
the Secretariat to assist in a dispute. 
When the Director-General, in the light of his co nsideration, including of available Secretariat 
resources, decides that a potential conflict of interest is not sufficiently material to warrant non-assignment of a 
particular member of the Secretariat to  assist in a dispute, the Director-G eneral shall inform the panel of his 
decision and of the relevant supporting information." WT/AB/WP/4 
Page 19 
 
 
 VII. Confidentiality  
 
1. Each covered person shall at all times main tain the confidentiality of dispute settlement 
deliberations and proceedings together with any info rmation identified by a party as confidential.  No 
covered person shall at any time use such info rmation acquired during su ch deliberations and 
proceedings to gain personal a dvantage or advantage for others. 
 2. During the proceedings, no c overed person shall engage in ex parte  contacts concerning 
matters under consideration.  Subject to paragr aph VII:1, no covered person shall make any 
statements on such proceedings or the issues in dis pute in which that person is  participating, until the 
report of the panel or the Standing Ap pellate Body has been derestricted. 
  
 VIII.  Procedures Concerning Subsequent Disclos ure and Possible Material Violations  
 1. Any party to a dispute, conducted pursuant to the WTO Agreement, who possesses or comes 
into possession of evidence of a material violation of  the obligations of independence, impartiality or 
confidentiality or the avoidance of direct or indir ect conflicts of interest by covered persons which 
may impair the integrity, impartiality or confidentia lity of the dispute settlement mechanism, shall at 
the earliest possible time and on a confidential basis,  submit such evidence to the Chair of the DSB, 
the Director-General or the Standing Appellate  Body, as appropriate according to the respective 
procedures detailed in paragraphs VIII:5 to VIII: 17 below, in a written statement specifying the 
relevant facts and circumstances.  Other Members who possess or come into possession of such evidence, may provide such evidence to the parties to the dispute in the interest of maintaining the 
integrity and impartiality of the dispute settlement mechanism.  
2. When evidence as described in  paragraph VIII:1 is based on an  alleged failure of a covered 
person to disclose a relevant interest, relationship or matter, that failure to disclose, as such, shall not 
be a sufficient ground for disqualification unless there is also evidence of a material violation of the 
obligations of independence, impa rtiality, confidentiality or the avoidance of direct or indirect 
conflicts of interests and that the integrity, impar tiality or confidentiality of the dispute settlement 
mechanism would be impaired thereby. 
 
3. When such evidence is not provided at the earliest practicable time, the party submitting the 
evidence shall explain why it did not do so earlier a nd this explanation shall be taken into account in 
the procedures initiated in paragraph VIII:1.  
4. Following the submission of such evidence to th e Chair of the DSB, the Director-General of 
the WTO or the Standing Appellate Body, as sp ecified below, the procedures outlined in 
paragraphs VIII:5 to VIII:17 below shall be  completed within fifteen working days.

Page 20  
 
7. If, after having consulted with the person con cerned, the matter is not resolved, the Chair of 
the DSB shall forthwith provide all the evidence,  and any additional information from the person

inform the parties to the dispute and, as the case may be, the panelists, the arbitrator(s) or experts. 
 
8. In all cases, the Chair of the DSB, in consu ltation with the Director-General and a sufficient 
number of Chairs of the relevant Council or C ouncils to provide an odd number, and after having 
provided a reasonable opportunity for the views of th e person concerned and the parties to the dispute 
to be heard, would decide whether a material  violation of these Rules as referred to in 
paragraphs VIII:1 and VIII:2 above has occurred.  Wher e the parties agree that a material violation of 
these Rules has occurred, it would be expected that, consistent with maintaining the integrity of the 
dispute settlement mechanism, the disqualificati on of the person concerned would be confirmed. 
 9. The person who is the subject of the evidence sh all continue to participate in the consideration 
of the dispute unless it is decided that a material violation of these Rules has occurred. 
 
10. The Chair of the DSB shall thereafter take  the necessary steps for the appointment of the 
person who is the subject of the evidence to be form ally revoked, or excused from the dispute as the 
case may be, as of that time.   Secretariat  
 
11. If the covered person who is the subject of th e evidence is a member of the Secretariat, the 
party shall only provide the evid ence to the Director-General of  the WTO, who shall forthwith 
provide the evidence to the person who is the subjec t of such evidence and shall further inform the 
other party or parties to the dispute and the panel. 
 12. It shall be for the Director-General to take  any appropriate action in accordance with the Staff 
Regulations.
*** 
 13. The Director-General shall inform the parties to the dispute, the panel and the Chair of the 
DSB of his decision, together with relevant supporting information. 
  
Standing Appellate Body  
 14. If the covered person who is the subject of  the evidence is a member of the Standing 
Appellate Body or of the Standing Appellate Body support staff, the party shall provide the evidence 
to the other party to the dispute and the eviden ce shall thereafter be provided to the Standing 
Appellate Body.  15. Upon receipt of the evidence referred to in  paragraphs VIII:1 and VIII:2 above, the Standing 
Appellate Body shall forthwith provide it to the person who is the subject of such evidence, for 
consideration by the latter.  16. It shall be for the Standing Appellate Body  to take any appropriate action after having 
provided a reasonable opportunity for the views of th e person concerned and the parties to the dispute 
to be heard. 
                                                     
 
***Pending adoption of the Staff Regulations, the Dir ector-General would act in accordance with the 
following draft provision for the Staff Regulations: "If paragraph VIII:11 of the Rules of Conduct for the DSU 
governing the settlement of disputes is invoked, the Dir ector-General shall consult with the person who is the 
subject of the evidence and the panel and shall, if  necessary, take appropriate disciplinary action". WT/AB/WP/4 
Page 21 
 
 
 17. The Standing Appellate Body shall inform the parties to the dispute and the Chair of the DSB 
of its decision, together with relevant supporting information.  
*** 
 
18. Following completion of the procedures in paragr aphs VIII:5 to VIII:17, if the appointment of 
a covered person, other than a member of the Sta nding Appellate Body, is re voked or that person is 
excused or resigns, the procedures specified in the DSU for initial a ppointment shall be followed for 
appointment of a replacement, but the time peri ods shall be half those specified in the DSU.
****  The 
member of the Standing Appellate Body who, under that  Body's rules, would next be selected through 
rotation to consider the dispute, would automatica lly be assigned to the appeal.  The panel, members 
of the Standing Appellate Body hearing the appeal , or the arbitrator, as the case may be, may then 
decide after consulting with the parties to the di spute, on any necessary modifications to their working 
procedures or proposed timetable. 
 
19. All covered persons and Members concerned shall resolve matters involving possible material 
violations of these Rules as expeditiously as possibl e so as not to delay the completion of proceedings, 
as provided in the DSU.  20. Except to the extent strictly necessary to carry  out this decision, all information concerning 
possible or actual material violations of  these Rules shall be kept confidential. 
  
 IX. Review  
 1. These Rules of Conduct shall be reviewed with in two years of their adoption and a decision 
shall be taken by the DSB as to whether to continue, modify or terminate these Rules.
