Section 9. Power to ascertain net profits or market-value.

If the Court sees reason to think that the annual nett profits or the market-value of any such land, house or garden as is mentioned in section 7, paragraphs (v) and (vi), have or has been wrongly estimated, the Court may, for the purpose of computing the fee payable in any suit therein mentioned, issue a commission to any proper person directing him to make such local or other investigation as may be necessary, and to report thereon to the Court.
