Use of Search Warrants to obtain blood samples in DUI cases

Mr. Chang was successful in litigating the use of a search warrant to forcibly obtain a blood sample from an individual who refused to take breath test in a DUI case. He prevailed at the trial level and the State of Florida appealed the matter to the Florida Supreme Court. Currently, the law stands that law enforcement may NOT use a search warrant to obtain a blood sample in a misdemeanor DUI case.

Admissibility of Ballistics expert’s opinions that bullets are a “match” to a specific firearm

Mr. Chang most recently challenged the admissibility of a State’s Ballistic’s expert who initially testified that a cartridge casing was fired from a specific firearm to the “exclusion of every other firearm in the world”. He was successful in obtaining an order from the trial court limiting the State’s expert and their opinion of individualization. This litigation and the challenge to the admissibility of the “junk science” of ballistics is ongoing.
