The check is what the case is essentially being brought on. Everyone agrees that the firearm was purchased for the uncle, and that he legally could own the firearm.
The questions are basically three:
1. Did the BATF have the authority to change their interpretation of the law without a change in the statute?
2. Did the Congress intend for it to be illegal for a private party to purchase a gun for another private party if both of them could legally possess the firearm?
3. Was it illegal for the purchaser to lie on the 4473 form if the form did not represent the will of Congress?
Which was this.
