(2) Where a right or privilege of the Crown by way of copyright subsists in a work or published edition of a work, a person does not infringe that right or privilege by doing, or authorizing the doing of, an act in relation to the work or edition without the licence of the Crown if, assuming that that right or privilege of the Crown did not subsist in the work or edition, but copyright subsisted under this Act in the work or edition and was owned by a person other than the Crown, the person would not infringe the copyright of that owner in the work or edition by doing, or by authorizing the doing of, that act without the licence of the owner.
(3) Nothing in subsection (2) shall be taken to limit the duration of the right or privilege of the Crown by way of copyright in a work or published edition of a work.
