Was there a benefit to the website owner posting it on his site? Also, how did you even come to learn of this?
Is any of the information copyrighted?
Here is the problem I am seeing, potentially. Someone had it and someone gave it away, unless it was copyrighted. If that someone stole it, I could see a possible problem. But if it was given to someone and that someone gave it to someone else, without limitation, and that unlimited information (which is obviously known by many people, so it is not necessarily private, i.e. known by family members, friends, etc.) is then posted on someone's website, I am not finding a single NJ or CA law that would likely be implicated. People hear things they are permitted to repeat them - it is a freedom of speech
issue. You can hope they don't repeat a secret, for instance, and if you had a binding agreement with all the necessary elements to be a binding agreement, you could feasibly sue the breacher for divulging. But here there is no such allegation I don't think.
Same with documents, unless copyrighted OR otherwise privileged - i.e. medical records in the hands of your doctor - legally retains the right of confidentiality
/privacy. Cell phone numbers - not terribly private since dozens of people have them AND you could legally divulge your friend/family member's cell phone number if you wanted (not protected)...family history? Again, not privileged, from what I can see.
I wish had better news for you but I am not finding in a review of NJ or CA and definitely not federal. I wish I did!
Good luck, I hope it all works out for you.
