Election Investigations Guidebook elements, like fire, water, and humidity.423 For example, Elections Canada uses locked fireproof rooms as designated evidence control areas.424 Finally, SOPs should clearly state accountability policies for persons with access to designated control areas and provide disciplinary actions for misconduct, malpractice, or negligence with respect to evidence.425 Inspection To monitor inventory and security measures, investigation supervisors should periodically inspect the designated evidence control area.426 Inspections serve as an “important internal control” that allows for the early identification of problems or deficiencies in the evidence management system.427 Inspections should cover key issues, such as “security, access control, [and] missing evidence,” “general cleanliness and housekeeping of the area,” and “inventory levels, safety practices, and training of [staff].”428 To promote institutional learning, supervisors should record inspection results in writing.429 As an accountability mechanism, external institutions should be empowered to conduct periodic audits of evidence management. Audits promote institutional integrity, compliance with legal requirements, and adherence to SOPs and policies.430 To prevent arbitrary auditing and undue interference with an investigative body’s operations, state policies should set the schedule and scope of audits in advance. 423 Nielsen & Kleffner, supra note 408, at 55. 424 Canadian Investigators’ Manual Ch. 9, supra note 401, at 4. 425 Cf.
