Section 85.50. Termination of stay

Any order extending a stay pursuant to
  section 85.40 of this title may be vacated or modified if,  upon  motion
  of  any creditor affected thereby, the court finds, after a hearing: (a)
  that the municipality has failed to comply with a material provision  of
  the   repayment  plan;  or  (b)  that,  due  to  a  material  change  in
  circumstances,  the  repayment  plan  no  longer   complies   with   the
  requirements  of section 85.40 of this title. Upon the occurrence of the
  final act necessary to carry out fully all of the terms  and  provisions
  of  the  repayment  plan  with respect to those creditors who accept the
  plan or any benefits thereunder, the court, after a hearing, upon motion
  of any creditor or  of  the  municipality  or  its  emergency  financial
  control board, shall enter an order vacating any stay then in effect and
  permanently  enjoining  any  creditors  who  accepted  the  plan  or any
  benefits thereunder from commencing or continuing any action or  special
  proceeding  or  doing any other act within the scope of section 85.30 of
  this title relating to any contract, debt or obligation included in  the
  plan.
