What does public interest immunity (PII) permit?

• A. It permits disclosure of sensitive documents to the court.
• B. It allows withholding sensitive documents if disclosure would damage the public interest.
• C. It applies only to criminal cases.
• D. It requires disclosure of all documents in a party's possession.

Answer: (B)

Public interest immunity exists to protect information whose disclosure would harm the public, not to force disclosure. It allows the withholding of sensitive documents or evidence when releasing them would damage important public interests, such as national security, public safety, or the proper functioning of government. It isn’t limited to criminal cases and can apply in civil proceedings as well, and it doesn’t require every document to be disclosed—where PII applies, documents may be withheld or redacted.

So the statement that it permits withholding sensitive documents if disclosure would damage the public interest is the correct understanding.
