Yes, breath test results can be excluded in Mississippi when the testing process or device maintenance is defective or when statutory procedures are not followed. Courts look at whether the testing device was properly calibrated, whether officers followed required observation protocols, and whether the operation of the device complied with applicable standards. If documentation reveals gaps, a motion to suppress may be granted to keep those test results from jury consideration. Successful exclusion often hinges on timely acquisition of records and careful legal briefing that ties procedural or scientific faults to admissibility standards. In Beechwood, as elsewhere in Warren County, courts consider both the technical facts and how they fit the state’s legal requirements. Prompt action to request and preserve records increases the chance of a successful challenge.
