(1) Upon timely application anyone shall be permitted to intervene in an action (a) when a statute confers an unconditional right to intervene, or (b) when the applicant claims an interest relating to the property or transaction which is the subject of the action and is so situated that the disposition of the action may as a practical matter impair or impede the applicant's ability to protect that interest, unless that interest is adequately represented by existing parties.

(2) Anyone possessing a statutory right of intervention under (1)(a) above, may move the court to intervene in a pending action and, on failure of a party to file an objection within ten (10) days to the intervention and a notice of hearing on the objection, have an order allowing the intervention without appearing in court for a hearing.
