Alabama DUI: Mastering the Motion in Limine Defense

Introduction: The Threshold of an Alabama DUI Trial

Facing a DUI charge in Alabama is a serious matter with potentially life-altering consequences, including jail time, license suspension, and mandatory substance abuse programs. Before the trial even begins, a skilled Legal Expert focuses on pretrial procedure to dismantle the prosecution’s case. The strategy of filing a strong pretrial motion package, specifically utilizing the Motion in Limine, is one of the most successful methods to challenge the admissibility of the state’s evidence.

Differentiating Motions: Limine vs. Suppress

While often discussed together, it is essential to understand the difference between a Motion in Limine and a Motion to Suppress:

Targeted Defense Strategies via Motion in Limine

In the context of Alabama DUI defense, the motion is used to proactively exclude or limit reference to several categories of evidence, making the prosecution’s case much harder to prove.

1. Challenging Expert Testimony and Qualifications

One powerful strategy is to challenge the State’s “expert” witnesses, often the officers who administered the tests or the analysts who handled blood samples. A motion can be filed to:

Motion Target	Goal
Exclude Cumulative Experts	Avoid a “parade” of witnesses repeating the same opinion, which can unfairly amplify the prosecution’s claims.
Exclude Speculative Opinions	Strike down unsupported, speculative expert opinions that lack proper scientific foundation.
Challenge Officer Certification	Require strict proof of the testing officer’s current certification for administering breath or blood tests, a flaw that can sometimes lead to dismissal.

2. Excluding Field Sobriety Test (FST) Reliability References

While a Motion to Suppress challenges the *administration* of the FSTs (e.g., failure to follow proper procedure), a Motion in Limine can challenge the *opinion* that FSTs reliably prove intoxication. The defense may seek to exclude testimony that the tests are “fail/pass” or otherwise scientifically conclusive, arguing that factors like a medical condition, fatigue, or uneven surface make the results unreliable and unduly prejudicial.

3. Limiting Reference to BAC Test Results

In Alabama, a Blood Alcohol Concentration (BAC) of .08% or greater gives rise to a legal presumption of being under the influence. A strong defense can use a motion to limit how the prosecution references these results, especially in cases where the defense argues the reading was still in the absorption phase at the time of the arrest (retrograde extrapolation). They may also attempt to exclude results entirely if:

• The equipment was not properly calibrated or maintained.
• The chain of custody for a blood sample was compromised.
• The administration procedures for the test were violated.

Summary: Leveraging the Pretrial Advantage

1. The Motion in Limine is a crucial pretrial strategy to exclude evidence based on admissibility and prejudicial effect, complementing the Motion to Suppress, which addresses constitutional violations.
2. Key targets include highly prejudicial material, such as prior criminal history, to maintain focus solely on the facts of the current DUI charge.
3. A defense will challenge the admissibility of FSTs by highlighting subjectivity and external factors like medical conditions or environmental conditions.
4. Motions are used to challenge the foundation of scientific evidence, including the calibration records and chain of custody for BAC Testing equipment and samples.
5. A successful pretrial motion can significantly weaken the prosecution’s case, often leading to reduced charges or dismissal before a jury is even empaneled.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between a Motion in Limine and a Motion to Suppress in an Alabama DUI case?

A: A Motion to Suppress challenges evidence based on constitutional violations or illegal collection (e.g., no probable cause for the stop). A Motion in Limine challenges evidence based on admissibility, arguing it is too prejudicial, irrelevant, or confusing for the jury to hear under the Rules of Evidence.

Q: Can a Motion in Limine be used to exclude an officer’s observations?

A: Yes. A motion can be filed to exclude or limit an officer’s subjective or inflammatory observations that are contradicted by objective evidence (like video) or that are deemed unreliable due to factors like the defendant’s medical conditions.

Q: If I refuse a chemical test in Alabama, can that refusal be used against me?

A: Yes. While Alabama’s implied consent law allows for the refusal of a chemical test (with penalties like automatic license suspension), that refusal itself can be used as evidence against you in court, suggesting that you knew you were impaired.

Q: What is “Actual Physical Control” and how does it relate to DUI defense?

A: In Alabama, you can be charged with DUI if you are in “actual physical control” of a vehicle, even if you are not driving. Defense strategies often focus on challenging the elements of control, such as where the keys were located, whether the vehicle was running, and the location of the motorist in the car.
