(a) Any trained intervenor or fact-reporter who participates in an intervention shall not be liable in tort for any personal injuries caused by any act or omission in the course of an intervention unless the act or omission constitutes willful or wanton misconduct, and no such intervenor or fact-reporter shall be liable for any cause of action in the nature of invasion of privacy, infliction of emotional distress, interference with family or business relationships, or defamation, unless that person acted with actual malice or willful intent to injure the subject of the intervention.
     (b) No public or private organization or agency, or any officer, director, trustee, employee, consultant, or agent of any such entity, that sponsors, authorizes, supports, finances, or supervises the training of intervenors or fact-reporters shall be liable for damages in any civil action based on the training of intervenors, unless the allegedly wrongful act or omission constitutes willful or wanton misconduct. In addition, no such entity or person shall be liable for any cause of action in the nature of invasion of privacy, infliction of emotional distress, interference with family or business relationships, or defamation, unless that entity or person acted with actual malice or willful intent to injure the subject of the intervention.
     (c) No person who instructs a course for intervenors or fact-reporters shall be liable for damages in any civil action based on the acts or omissions of an intervenor or fact-reporter who received instruction on interventions by that instructor, unless the instruction given by such instructor constitutes willful or wanton misconduct. In addition, no such instructor shall be liable for any cause of action in the nature of invasion of privacy, infliction of emotional distress, interference with family or business relationships, or defamation, unless that instructor acted with actual malice or willful intent to injure the subject of the intervention.
     (d) Any fact-reporter who encourages an individual or an individual’s family members to seek treatment or who, as part of the intervention process, makes a report in good faith to a trained intervenor of any conduct that reasonably appears to indicate that an individual suffers from alcoholism or drug addiction shall have immunity from any liability, civil or criminal or otherwise, that might result as a consequence of making such a report, unless the person making the report is subject to a privilege recognized by the law of this State. The good faith of any fact-reporter making such a report shall be a rebuttable presumption.
     (e) All reports, findings, proceedings, and data relating to the course of any intervention, including steps taken in preparation and implementation, are confidential and privileged and are not subject to discovery or disclosure nor are they admissible in any proceeding including, but not limited to, any civil, administrative, or criminal proceeding, and no person who participates in an intervention shall be permitted or required to testify in any proceeding as to any evidence or other matters produced, presented, or considered during an intervention. However, information, documents, or other records otherwise available from original sources are not to be construed as immune from discovery or use in a proceeding merely because they were presented during an intervention.
