  216.
  
    Investigation
  
  of ownership of company.
  1.      Where it appears to
  
  the Central Government that there is a reason so to do, it may appoint one or
  
  more inspectors to investigate and report on matters relating to the company,
  
  and its membership for the purpose of determining the true persons—
  a.     
  
    who
  
  are or have been financially interested in the success or failure, whether real
  
  or apparent, of the company; or
  b.    
  
    who
  
  are or have been able to control or to materially influence the policy of the
  
  company.
  1.     
  2.      Without prejudice to
  
  its powers under sub-section (1 ), the Central Government shall appoint
  
  one or more inspectors under that sub-section, if the Tribunal, in the course
  
  of any proceeding before it, directs by an order that the affairs of the
  
  company ought to be investigated as regards the membership of the company and
  
  other matters relating to the company, for the purposes specified in
  
  sub-section (1 ).
  3.      While appointing an
  
  inspector under sub-section (1 ), the Central Government may define the
  
  scope of the investigation, whether as respects the matters or the period to 
  
  which it is to extend or otherwise, and in particular, may limit the
  
  investigation to matters connected with particular shares or debentures.
  4.      Subject to the terms
  
  of appointment of an inspector, his powers shall extend to the investigation of
  
  any circumstances suggesting the existence of any arrangement or understanding
  
  which, though not legally binding, is or was observed or is likely to be
  
  observed in practice and which is relevant for the purposes of his investigation.
