(2) Admission of the secondary evidence would be unfair.
(b) Nothing in this section makes admissible oral testimony to prove the content of a writing if the testimony is inadmissible under Section 1523 (oral testimony of the content of a writing).
(c) Nothing in this section excuses compliance with Section 1401 (authentication).
(d) This section shall be known as the “Secondary Evidence Rule.”
