To simplify the Rules of the Code I propose abolishing these ranks. The rank of Kingdom is mentioned once in the Code, in an example to Rule 8, but it is not further defined. Therefore, I propose modifying that example so that the rank of Kingdom is no longer mentioned in the Code. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003317
