Section 1124. Execution thereof

The commissioner or commissioners possess
  the same powers, and must proceed in the  same  manner,  as  a  referee,
  appointed  by  an order requiring the production of the tenant for life,
  or proof of his existence; except that  they  cannot  proceed  unless  a
  person  is  produced  before them, as being the person whose death is in
  question. The return to the commission must expressly state whether  any
  person was or was not so produced. The testimony respecting the identity
  of  a  person  so  produced  must  be  taken, unless otherwise specially
  directed by the court, as prescribed by law, for taking  the  deposition
  of  a  witness upon oral interrogatories except that it is not necessary
  to give any other notice of the time and place of examination than  that
  prescribed in section 1123.
