Important to note when discussing the SCOTUS Justices being members of the American Law Institute and 28 U.S. Code § 454.
ALI owns the copyright to the UCC and the UCC is it's long-term joint project with the NCCUSL.
UCC contained principles and concepts borrowed from German law. Notice the year it originally was released: 1952. Our Uniform Commercial Code was created through Project Paperclip.
