- Cal. Evid. Code §§ 1400-1401, 1552, 1553 — presumption of accuracy
What the court held
Photographs and video from an automated traffic-enforcement system were adequately authenticated by the testimony of an investigating officer, and were not hearsay. Testimony from a technician with special expertise in the operation and maintenance of the system's computers was not a prerequisite, and the court declined to require a greater authentication showing for digital images merely because digital images can in theory be altered.
Why
The court treated authentication as a subset of relevance and a preliminary fact for the trial judge: the proponent need only produce evidence sufficient to sustain a finding that the writing is what it is claimed to be. It relied on the statutory presumptions that printed representations of computer information and of images stored on video or digital media are accurate, while noting those presumptions do not excuse the authentication requirement altogether. Perceived errors in a particular computer's operation go to the weight of the evidence rather than its admissibility unless specifically challenged.
Our reading — not the court’s words
Why this matters in practice
Goldsmith is the authority that keeps machine-generated output from requiring a systems engineer every time it is offered, and it is the clearest statement that the theoretical alterability of digital images does not raise the foundational bar. The practical consequence cuts both ways: a challenge to automated output has to be specific — this system, this configuration, this failure mode — because a generic argument that digital evidence can be faked will be treated as a weight argument for the jury. Note that California's statutory presumptions have no exact federal analogue; the federal route to the same place runs through Rules 902(13) and 902(14).
