PURPOSE: This rule describes who may intervene in an action and how to intervene.

1. (1) The commission may permit any person to intervene if the person—

   1. (A) Files a motion for intervention within such time as not to delay unduly the hearing on the complaint; and
   2. (B) Has an interest in the action which is different from the general public interest and which cannot be represented adequately by the parties.

2. (2) A motion to intervene shall—

   1. (A) Be in writing;
   2. (B) Set forth facts showing that the person is entitled, or should be permitted, to intervene;
   3. (C) Be signed by the person or the person’s attorney;
   4. (D) Be accompanied by a pleading.
3. (3) The commission’s order, ruling on the motion to intervene, shall set the date on which intervenor’s pleading is filed. When the commission grants a motion to intervene as petitioner, a responsive pleading to the intervenor-petitioner’s complaint shall be due thirty (30) days after the date on which such intervenor-petitioner’s complaint is filed, as set by the commission’s order. A responsive pleading to the intervenor-petitioner’s complaint shall be otherwise governed by rule 1 CSR 15-3.380.
