Section 6510 Of Chapter 6. Permit Requirements From California Labor Code >> Division 5. >> Part 1. >> Chapter 6.

. (a) If, after inspection or investigation, the division finds that an employer, without a valid permit, is engaging in activity for which a permit is required, it may, through its attorneys, apply to the superior court of the county in which such activity is taking place for an injunction restraining such activity.
  (b) The application to the superior court, accompanied by an affidavit showing that the employer, without a valid permit, is engaging in activity for which a permit is required, is a sufficient prima facie showing to warrant, in the discretion of the court, the immediate granting of a temporary restraining order. No bond shall be required of the division as a prerequisite to the granting of any restraining order.
