Any insurance rating bureau which files any rating plan, manual, classifications, rules or rates for fire, marine or inland marine and allied risks insurance with the insurance department of the state of Indiana for its members or subscribers shall as a condition precedent to the filing of an application to act as a rating bureau in the state of Indiana, establish in its constitution or by-laws the right of domestic insurers organized and operating under the laws of the state of Indiana, who are members of such rating bureau, to have representation on the board of directors, board of governors or any other governing body whatsoever, controlling said rating bureau, in an amount of not less than thirty-three and one-third percent (33 1/3%) of all of the voting members of such governing body. The constitution and by-laws of said rating bureau shall also contain the condition that all meetings of the governing body of said rating bureau shall be held either in Chicago, Illinois or in Indianapolis, Indiana. However, this section does not limit the representation of such domestic insurers on said governing body. Indiana representatives on such governing body shall be nominated by special meeting of the Indiana members of such rating bureau at least ten (10) days preceding the election of representatives on the governing body of such rating bureau. The insurance commissioner of the state of Indiana shall have no right to approve any such rating bureau as a rating bureau in the state of Indiana until the aforesaid conditions are met by such bureau.
