Appellate Practice Attorney serving New York, NY
Assuming he got your phone number from publicly available information, it was not illegal for him to use it. It may constitute harassment if he calls back after being asked not to do so, but (although I'm not familiar with California law) I doubt that one or two unwanted phone calls, without any threats, would constitute the crime of harassment. You may want to speak to your phone company about what you can do, short of changing your number to an unlisted one.
