Section 7-707. Preliminary injunction

(a) Generally. Pending an action for a
  permanent   injunction   as  provided  for  in  section  7-706  of  this
  subchapter, the court may grant a  preliminary  injunction  enjoining  a
  public  nuisance  within  the scope of this subchapter and the person or
  persons conducting, maintaining or permitting the public  nuisance  from
  further  conducting,  maintaining  or permitting the public nuisance. An
  order granting a preliminary injunction shall  direct  a  trial  of  the
  issues  within  three  business days after joinder of issue or, if issue
  has already been joined, within three business days after the  entry  of
  the  order.  Where  a preliminary injunction has been granted, the court
  shall render a decision with respect to a  permanent  injunction  within
  three  business  days  after  the  conclusion  of the trial. A temporary
  closing order may  be  granted  pending  a  hearing  for  a  preliminary
  injunction  where  it  appears  by  clear and convincing evidence that a
  public nuisance within the scope of this subchapter is being  conducted,
  maintained  or  permitted  and that the public health, safety or welfare
  immediately requires the  granting  of  a  temporary  closing  order.  A
  temporary  restraining  order  may  be  granted  pending a hearing for a
  preliminary injunction where it appears by clear and convincing evidence
  that a public nuisance within the scope  of  this  subchapter  is  being
  conducted, maintained or permitted.
    (b)  Enforcement  of  preliminary injunction. A preliminary injunction
  shall be enforced by the city agency at  whose  request  the  underlying
  action  is  being  brought.  In the event the underlying action is being
  brought at the direction of the mayor, or at the request of several city
  agencies or by the corporation counsel, on his or her own initiative, or
  upon the request of a  district  attorney,  or  a  member  of  the  city
  council,  the  order  shall  be enforced by the agency designated by the
  mayor. The police department shall,  upon  the  request  of  the  agency
  involved  or  upon the direction of the mayor, assist in the enforcement
  of the preliminary injunction.
    (c) Preliminary injunctions, inventory, closing of  premises,  posting
  of  orders  and  notices,  offenses.  If  the court grants a preliminary
  injunction, the provisions of section 7-711 of this subchapter shall  be
  applicable.
