May I please trespass on the combined erudition of this board to ask their opinion on a work-related issue in unravelling some tangled syntax? The following passage is from the Australian Copyright Act,describing what is a "reasonable portion" for the purposes of the fair dealing (USn = fair use) defence to copyright infringement.

<<<<Without limiting the meaning of the expression reasonable portion in this Act, where a literary, dramatic or musical work (other than a computer program) is contained in a published edition of that work, being an edition of not less than 10 pages, a copy of part of that work, as it appears in that edition, shall be taken to contain only a reasonable portion of that work if the pages that are copied in the edition:

(a)do not exceed, in the aggregate, 10% of the number of pages in that edition; or
(b)in a case where the work is divided into chapters exceed, in the aggregate, 10% of the number of pages in that edition but contain only the whole or part of a single chapter of the work.>>>


First point is - if the book is divided into chapters must you go under (b) and are you precluded from using (a)?

Next: Does it mean, for a 100 page book, that you can copy
(a) an 8 page chapter OR indeed a 15 page chapter;or
(b) you can copy an 8 page chapter plus 1 or 2 more pages from the book (10 pages in all) but no more, or
(c) you can copy an 8 page chapter but not any more, and you cannot copy a single 15 page chapter?

There are no case authorities on point.
