Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether breath test results were properly admitted. | State argues proper foundation via admin procedures or expert. | Healy argues no adequate foundation due to procedural defects. | Yes; district court within discretion to admit with expert foundation. |
| Role of Charan in allowing admission despite procedural defects. | Charan supports admission when expert explains reliability. | Charan requires reliability despite defects; expert must explain safeguards. | Charan requires expert justification of reliability in case-specific context. |
| Effect of calibration procedure failings on reliability. | Procedures not mandatory; other safeguards exist. | Noncompliance with 4-sample check undermines reliability. | Reliability preserved by safeguards; four-sample check missing, but other safeguards suffice. |
| Whether breath testing specialist’s credentials suffice for expert foundation. | Specialist qualified by training and certification; admissible. | Not officially labeled as expert; may be insufficient. | Specialist qualified as expert based on training and experience. |
| Whether other safeguards aside from exact procedures ensure accuracy. | Safeguards like expiration dating, concentration range, and negative slope indicator. | Without full procedure compliance, safeguards may be inadequate. | Additional safeguards supported reliability of the test results. |
