For your lawyer
What this is, in evidence-law terms.
The record is designed to support self-authentication of electronic records under Federal Rules of Evidence 902(13) and 902(14). What weight it receives is for the court.
902(13)
Provides for self-authentication of a record generated by an electronic process or system that produces an accurate result, as shown by a certification of a qualified person.
902(14)
Provides for self-authentication of data copied from an electronic device, storage medium or file, if authenticated by digital identification, again as shown by a certification of a qualified person.
902(11) and 902(12)
Both operate through the certification route, which carries a notice requirement: the proponent must give an adverse party reasonable written notice of the intent to offer the record, and make the record and certification available for inspection, so the party has a fair opportunity to challenge it.
901(b)(9)
Remains available as the ordinary route: evidence describing a process or system and showing that it produces an accurate result.
What it establishes
- That a named reviewer made a specific declaration and signed a specific review of that exact file at the stated time, and that not one byte has changed since
What it leaves to the court
- Whether the declaration is accurate, and whether the review was sufficient. The software records what you state and never scores it
The four challenges
And the answers.
“Anyone could have made this file.”
The record is signed by a key created on the signer’s own machine. To establish who signed, a reader checks it against a key they already trust for that person, exactly as a signature is matched against one on file. On first contact the honest reading is: unchanged, signer not established. The record says so itself rather than implying more.
“Your client wrote the time themselves.”
Correct, if the record says self-asserted, and it does say so on its face. Where the time must be independent, the record can carry witnessed time from a public timestamp authority under RFC 3161, the same standard courts and archives already rely on. The verifier states which of the two it is looking at, in plain words.
“The declaration could be false.”
A signature does not make a false declaration impossible. It makes it permanent and attributable to the person who signed it, at a stated moment, bound to a specific file. A conversation you can talk your way around leaves no trace at all.
“So what? It only proves the file did not change.”
That is one of three. It also carries what a named person declared about their own process, and when. Taken together it is contemporaneous evidence of diligence, which is a different category from a declaration written after the question was asked.
