(a) INTERVENTION OF RIGHT. On timely motion, the court must
permit anyone to intervene who:
(1) is given an unconditional right to intervene by a federal
statute; or
(2) claims an interest relating to the property or transaction
that is the subject of the action, and is so situated that dispos-
ing of the action may as a practical matter impair or impede
the movant’s ability to protect its interest, unless existing
parties adequately represent that interest.
(b) PERMISSIVEINTERVENTION.
(1) In General. On timely motion, the court may permit any-
one to intervene who:
(A) is given a conditional right to intervene by a federal
statute; or
(B) has a claim or defense that shares with the main ac-
tion a common question of law or fact.
(2) By a Government Officer or Agency. On timely motion, the
court may permit a federal or state governmental officer or
agency to intervene if a party’s claim or defense is based on:
(A) a statute or executive order administered by the offi-
cer or agency; or
(B) any regulation, order, requirement, or agreement is-
sued or made under the statute or executive order.
(3) Delay or Prejudice. In exercising its discretion, the court
must consider whether the intervention will unduly delay or
prejudice the adjudication of the original parties’ rights.

(c) NOTICE AND PLEADING REQUIRED. A motion to intervene must
be served on the parties as provided in Rule 5. The motion must
state the grounds for intervention and be accompanied by a plead-
ing that sets out the claim or defense for which intervention is
sought.
