Section 1708.85 creates a private cause of action against a person who intentionally distributes, by any means, a photograph, film, videotape, recording or other reproduction of another without that person's consent. Three elements must be shown under subdivision (a): the distributor knew or reasonably should have known that the other person had a reasonable expectation that the material would remain private; the material exposes an intimate body part, or shows the person engaging in an act of intercourse, oral copulation, sodomy or other act of sexual penetration; and the person suffers general or special damages as described in § 48a. Subdivision (b) defines "intimate body part" as any portion of the genitals and, for a female, any portion of the breast below the top of the areola, uncovered or visible through less than fully opaque clothing.
The fact that the image was originally taken with consent is not a defence. What subdivision (a) turns on is the expectation that the material would stay private, which is exactly the position of images shared inside a relationship. Subdivision (c) lists six situations where there is no liability: the material was created under an agreement for public use or otherwise intended by the person for public distribution; the distributor had permission from the person appearing in it to publish or post it; the person waived any reasonable expectation of privacy by making it accessible to the general public; the material is a matter of public concern; it was recorded in a public place in circumstances with no reasonable expectation of privacy; or it had previously been distributed by another person — that last one only until the plaintiff serves a certified-mail notice to cease and the defendant fails to stop within 20 days.
Subdivision (d) allows equitable relief in addition to any other remedy, including a temporary restraining order and preliminary or permanent injunction ordering the material removed. The section also contains provisions allowing a plaintiff to proceed under a pseudonym. Taking action quickly, and preserving evidence of the distribution, are matters to discuss with a lawyer.
