1. Jurisdictional attack  - refer to link for information DUI case
           Attack the jurisdiction (power) of the court in the pending criminal case
           Jurisdictional attack may be an important concept in defense of any given eluding case

2. Lack of reasonable suspicion for initial attempted contact by the law enforcement officer

3. Lack of probable cause for warrantless arrest or seizure of the defendant's person

4. Color of authority - peace officer acting within course & scope of his or her employment.  

5. Unlawful extra-jurisdictional arrest

6. Defendant's admissions the result of undue influence, duress and coercion - due process violation

7. Defendant's admissions taken in violation of
           5th Amendment privilege against self incrimination
           6th Amendment right to legal counsel

8. Alleged offense did not occur on public roadway or highway? - yes, the defense works in drag racing cases

9. Driving
           A third person, not defendant, was driving a motor vehicle

10. Officer observations - what didn't he observe which a jury member might expect?  What was the officer's opportunity to observe? - lighting, time spent, temperature, etc.  

11. Officer credibility.  Experience with traffic enforcement and training, over concern with conviction statistics, a cop's cop or an average Joe doing a job, would the jury members want this particular officer stopping him / her?  Has the officer overstated his / her observations in relation to the driving behavior?  How well was the stop and investigation conducted?

12. Eluding is a factual determination based upon the circumstances of the case.  The case may turn upon factual argument - defendant's conduct & driving pattern and officer conduct.

13. Reasonable doubt - state proof beyond a reasonable doubt

14. Cloak of innocence and burden of proof upon state - beyond a reasonable doubt.  A defendant is not required to prove innocence - the state must prove guilt.

15. When all else fails:

16. Trial lawyer's adage:
            If the facts are on your side - pound the facts.
            If the law is on your side - pound the law.
            If neither the facts nor the law are on your side - pound the table !
