Provision 5 cont. 



documented statement of the relevant facts; when a request 

 is not supported by adequate evidence it shall be returned to 

 the author for revision. When an Opinion is challenged the 

 basis of the challenge shall be stated and supported by a 

 documented statement of the relevant facts. 



In suitable cases an Opinion shall be prepared which, 

 if approved by eight or more Conunissioners, shall be issued 

 and published, becoming thereby available for the guidance 

 of bacteriologists. All Opinions are reported to the Inter- 

 national Committee on Bacteriological Nomenclature and, 

 unless rescinded by majority vote of this Committee, such 

 Opinions become final. 



(3) To consider each proposal for amendment of the Inter- 

 national Bacteriological Code of Nomenclature and to 

 formulate a recommendation for such amendment. When 

 approved by eight or more Commissioners, it shall be sub- 

 mitted to the members of the International Committee on 

 Bacteriological Nomenclature and shall be considered as 

 tentatively approved when it has been accepted by seventy 

 per cent of the members voting. It shall be submitted for 

 final approval to the next Plenary Session of an Interna- 

 tional Congress. 



(4) To exercise the plenary powers conferred upon the Com- 

 mission by the International Bacteriological Code of Nomen- 

 clature and by the Fourth Congress of the International As- 

 sociation of Microbiologists to suspend the rules as applied 

 to any given case, where, in its judgment, the strict appli- 

 cation of the Rules will clearly result in greater confusion 

 than uniformity. If the suspension of the rules is by unani- 

 mous vote of the Commissioners, the decision is final, except 

 that an appeal may be taken to the International Commit- 

 tee on Bacteriological Nomenclature, which may rescind the 

 action by majority vote of those voting. If the suspension of 

 the rules is initially approved by nine or more Commis- 

 sioners, but the vote is not unanimous, the resolution for 

 suspension shall be submitted to the members of the In- 

 ternational Committee on Bacteriological Nomenclature 

 and will be validated by an affirmative vote of seventy per 

 cent of those voting. 



(5) To establish lists of the names of taxonomic groups (taxa) 

 that are to be conserved (nomina conservanda) on the basis 

 of Opinions issued relative to the status of such names. 

 There shall be included a list of conserved generic names 



{nomina generica conservanda) together with a list of the
