If proof necessary to establish the grounds for eviction depends, in whole or in part, upon the affidavits or testimony of witnesses who are not peace officers, the court may, upon a showing of prior threats of violence or acts of violence by any defendant or any other person, issue orders to protect those witnesses, including the nondisclosure of the name, address, or any other information which may identify those witnesses. (1995, c. 419, s. 1.)
