Section 6-124. Conventions; judicial

A judicial district convention shall
  be constituted by the election at the preceding primary of delegates and
  alternate delegates, if any, from  each  assembly  district  or,  if  an
  assembly  district shall contain all or part of two or more counties and
  if the rules of the party shall so provide, separately from the part  of
  such  assembly district contained within each such county. The number of
  delegates and alternates, if any, shall be determined  by  party  rules,
  but  the  number  of delegates shall be substantially in accordance with
  the ratio, which the number of votes cast for the  party  candidate  for
  the  office  of governor, on the line or column of the party at the last
  preceding election for such office, in any unit of representation, bears
  to the total vote cast at such election for such candidate on such  line
  or  column  in  the  entire  state.  The  number  of alternates from any
  district shall not exceed  the  number  of  delegates  therefrom.    The
  delegates certified to have been elected as such, in the manner provided
  in  this  chapter, shall be conclusively entitled to their seats, rights
  and votes as delegates to such convention. When a duly elected  delegate
  does  not  attend the convention, his place shall be taken by one of the
  alternates, if any, to be substituted in his place, in the order of  the
  vote  received  by  each  such  alternate  as such vote appears upon the
  certified list and if an equal number of votes were cast for two or more
  such alternates; the order in which such alternates shall be substituted
  shall  be  determined  by  lot  forthwith  upon  the  convening  of  the
  convention.   If  there  shall  have  been  no  contested  election  for
  alternate, substitution shall be in the order in which the name of  such
  alternate  appears  upon  the certified list, and if no alternates shall
  have been elected or if no alternates appear at  such  convention,  then
  the  delegates  present  from  the same district shall elect a person to
  fill the vacancy.
