law: 304. Defining the regular line of streets.
  (1) The Commissioner may define a line on one or both sides of any public street in accordance with the bye-laws made in this behalf and may, with the previous sanction of the Corporation, redefine at any time any such regular line :
  Provided that, before according sanction the Corporation shall by public notice afford reasonable opportunity to the residents of premises abutting on such public street to make suggestions or objections with respect to the proposed redefined line of the street and shall consider all such suggestions or objections which may be made within one month from the date of the publication of the said notice:
  Provided further that the regular line of any public street operative under any law in force in any part of Delhi immediately before the commencement of this Act shall be deemed to be a line defined by the Commissioner under this subsection.
  (2) The line for the time being defined or redefined shall be called the regular line of street.
  (3) No person shall construct or reconstruct any building or a portion thereof or any boundary wall or other structure whatsoever within the regular line of a street except with the written permission of the Commissioner:
  Provided that if within sixty days after the receipt of application from any person for permission to construct or reconstruct a boundary wall or a portion thereof, the Commissioner fails to take steps to acquire the land within the regular line of the street in accordance with section 308, then, that person may, subject to any other provisions of this Act and the bye-laws made thereunder, proceed with the work of construction or reconstruction of such boundary wall or portion thereof.
  (4) When the Commissioner grants permission for the construction or reconstruction of any building or any boundary wall or other structure within the regular line of a street, he may require the owner of the building to execute an agreement binding himself and his successors-in-interest not to claim compensation in the event of the Commissioner at any time thereafter calling upon him or any of his successors by written notice to remove any work carried out in pursuance of such permission and to pay the expenses of such removal if, in default, such removal is carried out by the Commissioner and may for that purpose require such owner to deposit in the Municipal Fund such sum as may be determined by him.
  (5) The Commissioner shall maintain
  (a) a register containing such particulars as may be specified by him in this behalf with plans attached thereto showing all public streets in respect of which the regular line of the street has been defined or redefined and containing any other particulars which the Commissioner may deem necessary;
  (b) a register of all agreements executed under sub-section (4) and of all deposits made thereunder.
  (6) All such registers shall be open to inspection by any person on payment of such fee as may be prescribed by the Commissioner with the sanction of the Standing Committee.
  (7) Any agreement entered into in pursuance of sub-section (4) shall be in writing, shall be registered under the Indian Registration Act, 1908 (16 of 1908), and shall be deemed to be an agreement in respect of the land to which it relates and any condition contained in such agreement shall be deemed to be an obligation annexed to the ownership of the said land and enforceable against the successors-in-interest of the owner of such land.
