Owner of debtor corporation who was joined to a pendent civil suit does not have standing to challenge engagement of special counsel as veil-piercing expert in the bankruptcy suit on the basis that the appointee is affiliated with one of the creditors and would act in a manner adverse to the estate.
Standing is determined at the time of filing -- an after-acquired interest in the estate does not convert the plaintiff's interest to that of a creditor for purposes of standing.
