(1) When it appears that a person has engaged in, is engaging in, or is about to engage in any activity in violation of the uniform business practices set out in this chapter, the city may cause to be served a written investigative demand upon any person believed to have information, documentary material, or physical evidence relevant to the alleged or suspected violation. An investigative demand may require the person to testify under oath, to answer written interrogatories, or to produce relevant documentary material or physical evidence for examination, at a reasonable time and place.
(2) Prior to the time required to answer an investigative demand, or within 20 days after the demand’s service, whichever period is shorter, a petition to extend the return date, or to modify or set aside the demand may be filed in the Municipal Court.
(3) Service of any investigative demand under subsections (1) and (2) of this section shall be made in accordance with the laws of the State of Oregon governing service of summons in an action, or as otherwise directed by the municipal court.
(4) If any person after being served with an investigative demand under this section fails or refuses to obey the investigative demand, the city may, after notice, apply to the Municipal Court and, after hearing, request an order:
(a) Granting injunctive relief to restrain the person from engaging in any aspect of the business or activity that involved the alleged violation;
(b) Granting such other relief as may be required, until the person obeys the investigative demand.
(5) Any disobedience of any order of the Municipal Court under this section shall be punished as contempt of court.
