j.  A  comprehensive  index  and  a  summary  index  covering  the  Constitution and statutes of the state of Iowa.   7.  The  Code  Supplement  published  after  the  first  regular  session  of  the  general assembly shall include:   a.  All of the statutes of Iowa of a general and permanent nature which were enacted or amended during that session, except as provided in subsection 3, and  an  indication  of  all  sections  repealed  during  that  session,  and  any amendments to the Constitution of the State of Iowa approved by the voters at the preceding general election.   b.  A chapter title and number for each chapter or part of a chapter included.   c.  An index covering the material included.   8.  A  Code  or  Code  Supplement  may  include  appropriate  tables  showing  the disposition   of   Acts   of   the   general   assembly   and   other   reference   material   as determined by the Iowa Code editor in accordance with policies of the legislative council.     [C97, p. 5; S13, p. 3; C24, 27, 31, 35, 39, § 168; C46, 50, 54, 58, 62, 66, 71, 73, 75, 77, 79, 81, § 14.12; 82 Acts, ch 1061, § 2--4]     91 Acts, ch 258, §12     C93, § 2B.12     94 Acts, ch 1107, § 19   49 A number of editorial powers and duties are set out in the law as well.  What this means in practice is that, every two years, the entire statute law of the State of Iowa is reprinted.  The 2003 Code amounts to four thick volumes of about 1500 pages each.    50 What I am trying to demonstrate here is that a modern method exists of providing the  law  in  an  accessible  form  and  systematic  manner,  without  the  need  to  go through the session laws as they were passed by the Iowa legislature.  The session laws  of  Iowa  are  drafted  in  such  a  way  as  to  amend,  add  or  subtract  from  the Code, accepting its pattern of organisation.  It is the arrangements of these laws and the indexing that is the key to this accessibility. 51 With  modern  technology,  such  a  process  should  not  be  impossible  in  New Zealand.  In my view, it needs to be seriously considered.24                                                     24   This suggestion is not new. I first put it forward in 1979, Geoffrey Palmer Unbridled Power (Oxford University Press, Wellington, 1979) 82.    18
