Intervention of Parties
Section 101
Section 101.402 Intervention
of Parties
a) The Board may permit any person to intervene in any
adjudicatory proceeding. If a person seeks to intervene in an adjudicatory
proceeding, the person must file a motion to do so with the Clerk and serve a
copy of the motion on all parties to the proceeding. The motion must state the
grounds for intervention.
b) In determining whether to grant a motion to intervene, the
Board will consider the timeliness of the motion and whether intervention will
unduly delay, materially prejudice, or otherwise interfere with an orderly or
efficient proceeding.
c) Subject to subsection (b), the Board will permit any person to
intervene in any adjudicatory proceeding if:
1) The person has an unconditional statutory right to intervene
in the proceeding; or
2) It may be necessary for the Board to impose a condition on the
person.
d) Subject to subsection (b), the Board may permit any person to
intervene in any adjudicatory proceeding if:
1) The person has a conditional statutory right to intervene in
the proceeding;
2) The person may be materially prejudiced absent intervention;
or
3) The person is so situated that the person may be adversely
affected by a final Board order.
e) An intervenor will have all the rights of an original party to
the adjudicatory proceeding, except that the Board may limit the rights of the
intervenor as justice may require. The limits may include providing that: the
intervenor is bound by Board and hearing officer orders already issued or by
evidence already admitted; that the intervenor does not control any decision
deadline; and that the intervenor cannot raise issues that were raised or might
more properly have been raised at an earlier stage of the proceeding.
