Section 85.60. Modification of plan

At any time prior to the entry of an
  order approving or disapproving a repayment  plan  pursuant  to  section
  85.40  of  this  title,  the  municipality,  with  the  approval  of its
  financial emergency control board, or any such board with or without the
  approval of the municipality, may file modifications thereof, subject to
  the power of the court to enter an order prohibiting  the  filing  of  a
  further   modification   if   it  finds,  after  a  hearing,  that  such
  modification or any prior modification or the  repayment  plan  was  not
  filed  in  good  faith.  At any time subsequent to the entry of an order
  approving a repayment plan, any such modifications may only be filed  by
  leave  of the court, after a hearing. Upon the filing at any time of any
  modification of a  repayment  plan,  the  court  shall  hold  a  hearing
  pursuant  to  section  85.40  of  this  title  and  shall enter an order
  continuing or extending such stay as may then be in effect  pursuant  to
  section  85.30 or 85.40 of this title for such additional period of time
  as may be required to permit the court to enter  an  order  pursuant  to
  section 85.40 of this title with respect to the modified plan.
