Background

Charles M. Barker III was cited for operating a motor vehicle while using a mobile electronic device, in violation of Hawaii Revised Statutes § 291C-137(a). After a trial de novo, the District Court of the Third Circuit entered judgment against him on October 31, 2024.

Representing himself on appeal, Barker challenged the evidence and the citing officer’s credibility, alleged that body-camera evidence had been concealed, and argued that the State improperly failed to answer requests for admissions he served while the appeal was pending. His opening brief contained no statement of points of error or record references, but the Intermediate Court of Appeals nevertheless attempted to discern his arguments.

The Court’s Holding

The Intermediate Court of Appeals affirmed the traffic-infraction judgment. Barker did not order a transcript of the trial de novo, so the appellate record provided no basis to review his challenges to the sufficiency of the evidence or the officer’s observations. The court also declined to revisit witness credibility, explaining that credibility and evidentiary weight are matters for the factfinder.

The court rejected Barker’s remaining arguments. Although he asserted that the officer forged his signature and raised that allegation to impeach the officer’s credibility, the citation showed “COVID” in the signature space, and Hawaii’s civil traffic rules provide that the absence of a defendant’s signature does not void an infraction notice. The body-camera exhibit contained no grey or blank spots during the recording submitted to the court, and the State had no duty to answer Barker’s requests for admissions because Hawaii’s appellate rules do not provide for discovery.

Key Takeaways

  • An appellant must supply an adequate record, including necessary trial transcripts, to obtain review of evidence-based claims.
  • An appellate court will not reassess witness credibility or the weight of evidence determined by the trial court.
  • A missing defendant signature does not void a Hawaii civil traffic infraction notice, and appellate proceedings do not provide for requests for admissions.

Why It Matters

The order underscores that self-represented litigants must still provide the record and identify errors necessary for meaningful appellate review. Even when a court liberally attempts to discern inadequately presented arguments, it cannot evaluate trial evidence or credibility determinations without a sufficient record.

It also clarifies two procedural points in Hawaii traffic appeals: the lack of a defendant’s signature does not invalidate an infraction notice, and parties cannot use appellate proceedings to conduct discovery that should have occurred, if available, before or during trial.
