"Breathalyzer Elements for Admissibility"

A Rhode Island DUI Case will often times include evidence of breathalyzer or breath test results. Defense counsel should inform himself of the foundation that the prosecution must lay in order to qualify the particular intoxication test. In the absence of an adequate foundation, defense counsel should object to admission of results of the test. Although all states do not require proof of the same matters, items from the following list could reasonably be required by any court as a predicate, and defense counsel should be prepared to object to admission of the test results if any applicable items are not established by the prosecution:

1. That the subject was legally arrested for driving while intoxicated prior to the demand for the test;

2. That the operator of the device was properly trained and licensed;

3. That the operator and the device were under adequate supervision by an expert;

4. That the chemicals used were compounded properly;

5. That the test was administered in accordance with the test methods directed by the state agency that supervises intoxication test results.

6. That nothing alcoholic was in the subject's mouth for 15 to 30 minutes before the test;

7. That the person interpreting the results of the test was qualified to do so; and

8. That the reading of blood-alcohol content showed a violation of the state statute creating a presumption of intoxication.

In a Rhode Island DUI, DWI, or Driving Under the Influence criminal defense, the attorney of record should have an in depth knowledge of the constitutional requisites for the admissibility of evidence. All possible violations of the defendant's constitutional rights should be investigated. These would include (1) whether the police had probable cause to stop the defendant, (2) whether a legal arrest was made, (3) whether constitutional and statutory warnings were given, (4) whether probable cause to request a breath-alcohol or other scientific test existed, (5) whether a legal search and seizure occurred (6) whether the defendant's right to counsel was violated, and (7) whether a confession was legally obtained. In a Rhode Island Drunk Driving, DUI arrest or DWI prosecution, a criminal defense attorney should also be keenly aware that “operation” is an important element for the prosecution to prove. In other words, the prosecutor in Rhode Island must prove beyond a reasonable doubt that the DWI, DUI suspect actually was operating the vehicle while under the influence.
