16 International Code of Nomenclature 



Principle 10. 



PRINCIPLE 10. Bacteriologists are urged not to change the name of a taxon 

 without serious motives, based either on more profound knowledge of facts 

 or on the necessity of giving up a nomenclature that is contrary to the Rules 

 of this Code. 



ANNOTATIONS 



Principle 10. The corresponding Article 17 of the Botanical Code 

 (Seventh Botanical Congress, Stockholm, 1952) was included as a 

 Rule with a Recommendation which read: 



Art. 17. No one may change a name (or combination of names) 

 without serious motives, based either on more profound knowledge 

 of facts or on the necessity of giving up a nomenclature that is con- 

 trary to the rules of this Code. 



Recommendation 17A. Changes in nomenclature should be made 

 only after adequate taxonomic study. 



The Nomenclature Section of the eighth International Botanical 

 Congress (Paris, 1954) agreed that the above Article 17 should not 

 be included in the rules but transferred to Chapter I, Art. 2, under 

 "General Considerations, Guiding Principles and Definitions", and 

 that consideration should be given by the Editorial Committee to the 

 following substitute wording: 



No one can change a name (or a combination of names) without 

 serious motives based either on some adequate taxonomic study or 

 on the necessity of giving up a nomenclature that is contrary to the 

 rules of this Code. 



One may conclude that the phrase "based on more profound 

 knowledge of facts" may well be interpreted to mean "based upon 

 some adequate taxonomic study." 



The Zoological Code does not directly rule on the above problem.
