"The meaning of 'permanent' appears, at first blush, to be clear. But just as a museum’s permanent collection does not mean the works will stay in the collection for posterity and a permanent hair wave does not last a lifetime, neither does the term permanent necessarily mean forever. The word permanent takes on meaning in context and, in this case, within a statutory framework."
As we used to say in the 80s, using a phrase that seems quite well-suited to this textual analysis:
Word.
