Narrative Opinion Summary
The case concerns the appeal of a defendant convicted of driving under the influence of intoxicants (DUII), challenging the trial court's exclusion of evidence and limitation of cross-examination concerning the National Highway Traffic Safety Administration's (NHTSA) Field Sobriety Test Instructor’s Manual. The defendant contended that the trial court violated Oregon Evidence Code (OEC) 706 by preventing cross-examination of police officers using the NHTSA manual for impeachment, which was crucial to the defense's argument that the field sobriety tests were improperly administered due to misunderstanding the effects of prescribed medication. The trial court's exclusion of evidence related to the defendant's medical condition and medication effects was also challenged. The appellate court found that the trial court erred in limiting the cross-examination, noting that the error was not harmless due to its potential impact on the trial's outcome. The court concluded that the error was preserved for appellate review, as the substance of the evidence was adequately conveyed during the trial. Consequently, the court reversed the conviction and remanded the case for a new trial, declining to address additional evidentiary issues that could be reexamined upon retrial. The ruling emphasizes the necessity of allowing cross-examination based on reliable published materials and the importance of establishing a sufficient foundation for such evidence under OEC 706.

Application: The court determined that the trial court's error in excluding evidence was not harmless, as it impacted the defendant's ability to present his defense theory effectively.
Reasoning: The excluded evidence was critical to this theory and could not be deemed harmless error, as it was distinct from other evidence presented and likely would have influenced the jury's verdict.
Preservation of Error for Appellate Reviewsubscribe to see similar legal issues
Application: The court ruled that the defendant's challenge regarding the exclusion of evidence was preserved, as the substance of the evidence was made known to the court, fulfilling the requirements of OEC 103(1)(b).
Reasoning: The defendant's appeal contended that the error of denying cross-examination opportunity was not preserved due to the plaintiff's lack of an offer of proof. However, the court disagreed, stating that an error affecting a substantial right is preserved if the evidence's substance is made known to the court or is apparent from the context, as per OEC 103(1)(b).
