Upon commencement of CIRP, management vests in the Interim Resolution Professional, rendering an appeal filed in the corporate debtor's name by a suspended director incompetent. A later amendment to prosecute the appeal personally cannot relate back to cure that lack of authority or bypass the statutory appellate limitation; the appeal was therefore not maintainable. For an operational creditor's insolvency application, a pre-existing dispute must be real and plausible rather than feeble, spurious, or illusory, without requiring a mini-trial at admission. Quality and contractual-compliance objections concerning the HDPE pond liner did not meet that threshold, so debt and default supported CIRP admission.
