Virginia Code Title 27. Fire Protection § 27-60. Department to conduct investigations in certain cases; investigations may be private

The Department may petition an appropriate judicial officer to summons and compel the attendance of witnesses to testify in relation to any matter which is, by the provisions of this chapter, a subject of inquiry and investigation. It may also administer oaths and affirmations to such witnesses, and false swearing in any such matter shall be deemed perjury, and shall be punished as such. It may in its discretion take or cause to be taken the testimony on oath of all persons supposed to be cognizant of any facts or to have means of knowledge in relation to the matters as to which any examination is, in this chapter, required to be made, and shall cause the same to be reduced to writing. Investigations in relation to such matters may, in the discretion of the Department, be private, and persons other than those required to be present by the provisions of this chapter may be excluded from that place where such examination is held, and witnesses may be kept separate and apart from each other, and not allowed to communicate with each other until they have been examined.
