Common questions
Frequently Asked
3
What distinguishes an unwarranted invasion of personal privacy from a justified disclosure?+
The distinction turns on whether the privacy harm outweighs any public interest in the information. Courts and agencies balance the intimate or stigmatizing nature of the material against legitimate needs such as law enforcement, public safety, or government accountability.
Supporting sources
Does truth of the disclosed facts defeat a claim of unwarranted invasion of personal privacy?+
No. Privacy torts such as public disclosure of private facts protect against publication of true but highly offensive private information. Defamation requires falsity, but privacy claims often proceed on accurate yet intimate details taken from confidential sources.
Supporting sources
Can commercial or promotional use of personal images constitute an unwarranted invasion?+
Yes when the use involves intimate or identifying material obtained without consent and distributed for marketing purposes. The commercial motive often strengthens the finding that the publicity is unreasonable and lacks public-interest justification.
