(a) Entities Entitled to Accept or Reject Plan; Time For Acceptance or Rejection. A plan may be accepted or rejected in accordance with § 1126 of the Code within the time fixed by the court pursuant to Rule 3017. Subject to subdivision (b) of this rule, an equity security holder or creditor whose claim is based on a security of record shall not be entitled to accept or reject a plan unless the equity security holder or creditor is the holder of record of the security on the date the order approving the disclosure statement is entered or on another date fixed by the court, for cause, after notice and a hearing. For cause shown, the court after notice and hearing may permit a creditor or equity security holder to change or withdraw an acceptance or rejection. Notwithstanding objection to a claim or interest, the court after notice and hearing may temporarily allow the claim or interest in an amount which the court deems proper for the purpose of accepting or rejecting a plan.
(b) Acceptances or Rejections Obtained Before Petition. An equity security holder or creditor whose claim is based on a security of record who accepted or rejected the plan before the commencement of the case shall not be deemed to have accepted or rejected the plan pursuant to § 1126(b) of the Code unless the equity security holder or creditor was the holder of record of the security on the date specified in the solicitation of such acceptance or rejection for the purposes of such solicitation. A holder of a claim or interest who has accepted or rejected a plan before the commencement of the case under the Code shall not be deemed to have accepted or rejected the plan if the court finds after notice and hearing that the plan was not transmitted to substantially all creditors and equity security holders of the same class, that an unreasonably short time was prescribed for such creditors and equity security holders to accept or reject the plan, or that the solicitation was not in compliance with § 1126(b) of the Code.
(c) Form of Acceptance or Rejection. An acceptance or rejection shall be in writing, identify the plan or plans accepted or rejected, be signed by the creditor or equity security holder or an authorized agent, and conform to the appropriate Official Form. If more than one plan is transmitted pursuant to Rule 3017, an acceptance or rejection may be filed by each creditor or equity security holder for any number of plans transmitted and if acceptances are filed for more than one plan, the creditor or equity security holder may indicate a preference or preferences among the plans so accepted.
(d) Acceptance or Rejection By Partially Secured Creditor. A creditor whose claim has been allowed in part as a secured claim and in part as an unsecured claim shall be entitled to accept or reject a plan in both capacities.
