Well, the suit that overturned his bonus was a single shareholder suit and that one was obviously successful.
I have been surprised there haven’t been more shareholder suits to be honest. They could challenge fiduciary responsibility on the basis of him robbing Peter to pay Paul by raiding Tesla for engineers, not to mention dividing his own time and effort between too many unrelated interests.
I believe that’s not the law though. The law outlines the conditions under which a person has an “expectation of privacy.” If you’re inside your house, you have an expectation of privacy and so should not be filmed. If you’re on the sidewalk in public, you have no expectation of privacy. If you’re in a private establishment (restaurant or store for instance), the owner or their representatives can ask you not to record and you have to comply.
All of street photography depends on this kind of legal framework.
