law: Trade Monopolies and Restrictive Trade Practices Act, 1969 
  42. Power of Director General to Obtain Information.
  (1) If the Director General has
  
  reasonable cause to believe that any person is a party to an agreement subject
  
  to registration under section 35, he may give notice to that person requiring
  
  him within such time, not less than thirty days, as may be specified in the
  
  notice, to notify to the Director General whether he is a party to any such
  
  agreement and, if so, to furnish to the Director General such particulars of
  
  the agreement as may be specified in the requisition.
  (2) The Director General may give
  
  notice to any person by whom particulars are furnished under section 35 in
  
  respect of an agreement or to any other person being a party to the agreement
  
  requiring him to furnish to the Director General such further documents or
  
  information in his possession or control as the Director Genral may consider
  
  expedient for the purpose of, or in connection with, the registration of the
  
  agreement.
  
  
  (3) Where a notice under this section is given to a trade association, the
  
  notice may be given to the secretary, manager or other similar officer of the
  
  association and for the purposes of this section any such association shall be
  
  treated as a party to an agreement to which members of the association, or
  
  persons represented on the association by those members, are parties as such.
  (4) If the particulars called for
  
  under sub-section (1), or sub-section (2) are not furnished, the Commission
  
  may, on the application of the Director General-
  (a) order the person
  
  or, as the case may be, the association to furnish those particulars to the
  
  Director General within such time as may be specified in the order, or
  (b) authorise the
  
  Director General to treat the particulars contained in any document or
  
  information in his possession as the particulars relating to the agreement, or
  (c) in case the
  
  Commission is satisfied that the failure to furnish the particulars is wilful,
  
  make an order restraining wholly or partly the parties to the agreement from
  
  acting on such agreement and from making any other agreement to the like
  
  effect.
