(1) For the purpose of an inquiry under section 8, the Court may depute, or issue a commission to, any suitable person to make such local or other investigation as may be necessary and to report thereon to the Court. Such report and any evidence recorded by such person shall be evidence in the inquiry.
(2) The Court may, from time to time direct such party to the suit as it thinks fit to deposit such sum as the Court thinks reasonable as the costs of the inquiry, and if the costs are not deposited within such time as the Court shall fix may, notwithstanding anything contained in any other Act, reject the plaint or, as the case may be the appeal, if such party is the plaintiff or the appellant and, in any other case, may recover the costs as a public demand:
Provided that when any plaint or appeal is rejected under this section, the court-fees already paid shall not be liable to be refunded.
