Resolution plan modification permitted once and committees must reject late, ineligible, or non compliant plans. Amendments impose an obligation on committees and members to comply with Board guidelines in conducting corporate insolvency resolution processes; restrict modification of invitations for expression of interest to the original manner and to a single instance; authorize the resolution professional to allow a one-time modification of a resolution plan or use a challenge mechanism; and require the committee to reject plans submitted after the committee deadline, from persons not on the final applicant list, or not meeting statutory submission requirements and regulatory conditions.
