Final answer:
The legal department should be advised of requests for reviewing or providing certified copies of original recordings that may serve as evidence in a non-government investigation due to their responsibility in handling legal and privacy aspects.
Step-by-step explanation:
When dealing with requests for reviewing or providing certified copies of original recordings that may be used as evidence in a non-government investigation, advisement is typically a job for the legal department. This department is responsible for managing the organization's legal affairs, including compliance with laws and regulations related to evidence handling and privacy concerns. The legal department will coordinate with other departments such as IT for technical aspects, with privacy officers for data protection issues, and with compliance officers for adherence to regulatory requirements. Knowing when to involve these various departments can be informed by principles found in the Constitution, such as 'he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices...' Additionally, the Freedom of Information Act (FOIA) includes reasonable exceptions such as the nondisclosure of medical records for government employees, showcasing the importance of having a knowledgeable legal team to navigate these complexities.
