RULE 24
                        INTERVENTION

    (a) Intervention of Right. Upon timely application, anyone shall be
permitted to intervene in an action: (1) when a statute confers an
unconditional right to intervene; or (2) when the applicant claims an
interest relating to the property or transaction which is the subject of
the action and he is so situated that the disposition of the action may as
a practical matter impair or impede his ability to protect that interest,
unless the applicants interest is adequately represented by existing
parties.
    (b) Permissive Intervention. Upon timely application, anyone may be
permitted to intervene in an action: (1) when a statute confers a
conditional right to intervene; or (2) when an applicants claim or defense
and the main action have a question of law or fact in common. When a party
to an action relies for ground of claim or defense upon any statute or
executive order administered by a federal or state governmental officer or
agency or upon any regulation, order, requirements, or agreement issued or
made pursuant to the statute or executive order, the officer or agency upon
timely application may be permitted to intervene in the action. In
exercising its discretion the court shall consider whether the intervention
will unduly delay or prejudice the adjudication of the rights of the
original parties.
    (c) Procedure. A person desiring to intervene shall serve a motion to
intervene upon all parties as provided in rule 5. The motion shall state
the grounds therefor and shall be accompanied by a pleading setting forth
the claim or defense for which intervention is sought.
