ChargeOWI First Offense
Reported Test.17 Breath Result
CourtOutagamie County
AttorneyDan Skarie
The client was a woman in her late 50s with no prior legal issues. After drinking beer at a fall festival in the Appleton area, another motorist reported that her vehicle had been weaving and had nearly entered a ditch.
An officer later stopped the vehicle and reported slurred speech, bloodshot eyes, and clues on field sobriety testing. The defense compared those claims with the available video and challenged the administration and scoring of the tests.
The court found enough reasonable suspicion for the initial stop, but it determined that the State had not established probable cause for the arrest.
Why the Distinction Mattered
A lawful traffic stop does not automatically make a later arrest lawful. The State must justify each stage independently.
Case Timeline
How the Matter Developed
The sequence matters because each stage carries its own evidentiary and legal requirements.
02
Traffic Stop
The officer observed the vehicle near the fog line and initiated the stop.
03
Suppression Hearing
Video and cross-examination challenged the field-test scoring and the officer’s interpretation of impairment.
04
Court Ruling
The stop was upheld, but the court found insufficient probable cause for arrest.
05
Dismissal
Once the .17 breath result was suppressed, the State dismissed the case.
Evidence Review
What Mattered Most
The defense focused on the evidence capable of changing how the allegation was understood.
01
Police Video
The footage allowed the court to compare the written report with the client’s actual behavior and test performance.
02
Field-Test Administration
Cross-examination addressed how HGN and the divided-attention tests were administered and scored.
03
Client Context
Age, fatigue, balance, and the circumstances of the day were relevant to interpreting roadside performance.
Defense Strategy
Build the Motion Around Objective Evidence
The defense did not rely on a general claim that the officer was wrong. It identified specific discrepancies between the report, the video, and the test administration.
- Analyze reasonable suspicion and probable cause as separate legal issues
- Compare every reported clue with the available recording
- Challenge test administration and scoring through cross-examination
- Place balance and fatigue evidence in the correct context
- Connect the evidentiary weaknesses to the legal standard for arrest
Final Outcome
Motion Granted. Evidence Excluded. Case Dismissed.
The court suppressed the breath-test evidence after finding that the State had not established probable cause for the arrest. Without that evidence, the prosecution dismissed the case.
- Traffic stop upheld
- Probable cause for arrest rejected
- .17 breath result excluded
- OWI case dismissed
Past results do not guarantee a similar outcome. Every matter depends on its own facts, evidence, court, prosecutor, prior record, and applicable law.

These answers are general. The correct analysis depends on the facts, notices, evidence, and procedural history of the individual matter.

Yes. Instructions, timing, scoring, surface conditions, footwear, medical issues, fatigue, and video can affect reliability.
It allowed the court to evaluate the client’s conduct directly instead of relying only on the written report.
No. The result must still be lawfully obtained, reliable, and admissible.
