Section 213. Enforcement proceedings against redevelopment corporations

Whenever  a  redevelopment  corporation  shall  not  have  obtained  the
  certificates of approval of its development plan required by section two
  hundred  three  of  this  article  within twelve months of the date upon
  which  it  became  a  redevelopment  corporation,  or  shall  not   have
  substantially  complied with its development plan within the time limits
  for the completion of each stage thereof as therein  stated,  reasonable
  delays  caused  by unforeseen difficulties excepted, or shall do, permit
  to be done or fail or omit to do anything contrary to or required of it,
  as the case may be, by this article, or shall be about so to do,  permit
  to  be  done  or fail or omit to have done, as the case may be, then any
  such fact may be certified by the planning commission or the supervising
  agency, whichever shall have supervision thereof,  to  the  chief  legal
  officer  of  the  city,  who  may thereupon commence a proceeding in the
  supreme court of the state of New York in its name for  the  purpose  of
  having  such  action, failure or omission, or threatened action, failure
  or omission, established by order of the court for the purpose stated in
  subdivision two of section two hundred five of this article, or stopped,
  prevented or otherwise rectified by order, injunction or otherwise. Such
  proceeding shall be  commenced  by  a  petition  to  the  supreme  court
  alleging the violation complained of and praying for appropriate relief.
  It  shall  thereupon  be  the duty of the court to specify the time, not
  exceeding twenty days after service of a copy of  the  petition,  within
  which  the  redevelopment  corporation  complained  of  must  answer the
  petition. The court shall, immediately after a default in  answering  or
  after   answer,  as  the  case  may  be,  inquire  into  the  facts  and
  circumstances in such manner as the court shall direct without other  or
  formal  proceedings,  and without respect to any technical requirements.
  Such other persons or  corporations  as  it  shall  seem  to  the  court
  necessary  or  proper  to  join as parties in order to make its order or
  judgment effective may be joined as parties. The final judgment or order
  in any such action or proceeding shall dismiss the action or  proceeding
  or  establish  the  failure complained of or direct that an order, or an
  injunction, or both, issue, or grant such other relief as the court  may
  deem appropriate.
