Section 8. If  a  majority  of  votes  cast  upon  an  initiated  or  a  referred  measure  are 
affirmative, it shall be deemed enacted. An initiated or referred measure which is approved 
shall become law thirty days after the election, and a referred measure which is rejected shall 
be  void  immediately.  If  conflicting  measures  are  approved,  the  one  receiving  the  highest 
number of affirmative votes shall  be law. A measure approved by the electors may not be 
repealed or  amended by the  legislative  assembly  for  seven years  from its  effective  date, 
except by a two-thirds vote of the members elected to each house.
