The Hawaii Intermediate Court of Appeals has upheld a speeding ticket issued to Michael Yellen, affirming the lower court's decision regarding discovery and due process. This ruling affects individuals who contest traffic infractions and seek extensive documentation from the state.

The case, State v. Yellen, was filed under docket number CAAP-25-0000412. It began when Yellen received a Notice of Traffic Infraction on November 12, 2024, for exceeding the speed limit. The ticket indicated that a radar device measured his speed, and the police officer who issued the ticket was certified to use the device. Yellen contested the ticket, leading to a series of legal actions.

Yellen, who represented himself in court, sought to compel the state to provide documentation about the radar device used to measure his speed. He requested details on the manufacturer's recommended procedures for ensuring the device's accuracy, including calibration methods. However, the state did not produce the requested documents, and the district court denied Yellen's motion to compel discovery. Following a trial, the court ruled in favor of the state, leading Yellen to appeal the decision.

The court ruled on September 29, 2026, affirming the district court's judgment. Chief Judge Karen T. Nakasone, along with Associate Judges Keith K. Hiraoka and Sonja M.P. McCullen, stated, "No statute or rule authorizes the discovery Yellen sought to compel from the State." The judges clarified that traffic infraction trials do not provide for discovery, which was a central issue in Yellen's appeal.

The court further noted that traffic infractions are not classified as criminal offenses in Hawaii, and as such, do not afford the same rights to discovery as criminal cases. The judges explained that the applicable rules and statutes do not support Yellen's claims for the documentation he sought.

In addition to the discovery issue, Yellen argued that he was denied his constitutional right to due process. The court interpreted this as a claim of being deprived of a fair opportunity to defend himself. The judges pointed out that Yellen received notice of the radar evidence used against him and had the chance to challenge the officer's testimony during the trial.

The ruling emphasized that Yellen did not include the trial transcript in the appeal record, which limited the court's ability to assess whether he was indeed deprived of due process. The judges stated, "The burden is upon appellant in an appeal to show error by reference to matters in the record," indicating that it was Yellen's responsibility to provide sufficient evidence to support his claims.

The court ultimately concluded that Yellen did not meet the burden of proof required to show error in the district court's ruling. Therefore, the court affirmed the district court's judgment, maintaining the validity of the speeding ticket and the procedures followed in the case.

This ruling has implications for individuals contesting traffic infractions in Hawaii. It clarifies the limitations on discovery in traffic cases and reinforces the importance of adhering to procedural rules when appealing a decision. It also highlights the necessity for self-represented litigants to provide comprehensive records to support their claims in court.

Looking forward, this decision may influence how future traffic infraction cases are handled in Hawaii. Individuals contesting similar charges may need to reconsider their approach to discovery and ensure they understand the limitations set by existing laws and court rules. As for Yellen, it is unclear whether he plans to pursue further legal action or if there are related cases pending that could address similar issues.
