Our firm has been successful in getting breath tests thrown out due to errors in administration of the test as well as mechanical defects and failure to properly maintain the equipment pursuant to the state regulations. With regard to blood testing, few lawyers have the experience or track record in challenging the collection, chain of custody and laboratory protocols. We use this extensive experience to suppress the blood test in Court and at the DMV.

In the last few years Matthew has also prevailed in perfecting successful challenges to the state's blood tests. Matthew has been trained on the gas chromatograph machine that many California Labs use to test the blood alcohol concentration of a suspect following a DUI arrest. He has received special training to interpret the "chromatograms" that are generated in each analysis of blood, looking for anomalies and problems that can often be pointed to in detecting errors by lab workers.

In recent years California has seen an increase in the prosecution of marijuana DUI cases, it is in this area that Matthew has kept abreast of the scientific testing and legal defenses unique to cannabis and pot cases. For example, he understands the nuances in blood testing that can make the difference between a dismissal and a conviction for driving under the influence.
