A new gun law takes effect in CA in Jan 2017 that requires all previously exempt antique black powder weapons to be registered with the State, and issued with a serial number that must be stamped or engraved in a clearly visible location and manner.
Please cite the specific law that you think imposes this requirement.
I know there have been cases where the owners of property lost value due to government action and were able to successfully argue that the loss was a "taking".
Can you cite any such case? If not, how do you purport to "know" these cases exist?
Anyone have an opinion as to whether that might work here?
The only case I've ever heard of involving an alleged taking of personal property is a case called Andrus v. Allard. I've never actually read the case, but my understanding is that holding essentially makes it almost impossible to prove a taking of personal property -- even if the governmental regulation renders the property without ANY economic value.
