Attacking and Defending Drunk Driving Tests
________________________________________

by Don Bartell and Anne ImObersteg

How to overcome the presumption of guilt in DUI trials


Voir dire strategies, cross-examination questions, and science to help you convince the jury that your DUI case deserves an honest review
Question-by-question and argument-by-argument, Attacking and Supporting Drunk Driving Tests explains how to soften resolute juries by picking apart unyielding police reports and bulletproof lab reports.

These courtroom-proven strategies are supported with understandable science in a coordinated trial attack that will leave the prosecution wondering how its formerly solid case became so weak.

This winning approach to DUI trials is presented step-by-step, and is heavily-supported with pattern arguments, model cross-examinations, case law, science, and motions. The text is filled with helpful suggestions.

More than a test-attack manual
This big book is a complete strategy, law, science, and forms guide containing tactics and arguments found nowhere else. While it focuses on attacking drunk driving tests, it also takes you step-by-step from discovery and investigation through motion practice to trial. It includes:
Pattern motions, with points and authorities
• Suppressing all evidence from a stop for weaving. §18:3
• Suppressing a breath or blood test taken after a PAS test. §18:4
• Challenging a drunk driving checkpoint. §18:7
• Excluding evidence of tolerance. §18:9
• Introducing partition ratio evidence. §18:11
• Denial of choice of test. §18:13
• Limiting the use of the horizontal gaze nystagmus test. §18:15
Proven trial tactics
• What response should you give to a judge who asks during the pretrial conference what is your defense? §20:50
• What formulas should you know before you go to court? §20:31
• Why develop a time line? §20:20
• What question should the defense ask every time there are two police officers testifying in the case? §20:99
• What can you do to minimize the effects of bad facts? §20:60
• How can you have the client testify without the client taking the stand? §20:51
• Where in the trial can the defense give a rebuttal statement? §20:75
