Section 6301. Grounds for preliminary injunction and temporary restraining order

A preliminary injunction may be granted in any action  where  it
  appears  that  the defendant threatens or is about to do, or is doing or
  procuring  or  suffering  to  be  done,  an  act  in  violation  of  the
  plaintiff's  rights respecting the subject of the action, and tending to
  render the judgment ineffectual, or in any action  where  the  plaintiff
  has  demanded  and  would  be  entitled  to  a  judgment restraining the
  defendant from the commission  or  continuance  of  an  act,  which,  if
  committed  or continued during the pendency of the action, would produce
  injury to the plaintiff. A temporary restraining order  may  be  granted
  pending  a  hearing  for  a preliminary injunction where it appears that
  immediate and irreparable injury, loss or damage will result unless  the
  defendant is restrained before the hearing can be had.
