Botanical nomenclatural query

If I may restate the issue here at hand (as I understand it):
If a taxon is raised to a new rank it is the custom to retain the epithet of
the former rank.
The question is, does this custom have a basis in the ICBN, either as a rule
or as a recommendation? Or is this by implication only?
What is to stop anybody who dislikes current epithets from moving these taxa
to a new rank (say from a variety to a subspecies or vice versa) and
attaching new epithets?
