Yes. Breath and blood test results can be excluded when the defense demonstrates that testing or handling procedures were flawed, documentation is missing, or lab practices were unreliable. Courts in Pascagoula consider the reliability of evidence and whether procedures met applicable standards. A suppression motion can outline these deficiencies and request exclusion of the test results from trial. Successful exclusion often depends on the specific facts, records, and legal arguments presented in Jackson County court. A thorough document review and clear presentation of procedural defects are usually necessary to prevail. To build such a motion, counsel will obtain and analyze calibration logs, operator records, chain of custody documentation, and laboratory reports. If those records contain omissions or reveal deviations from required protocols, the defense can argue that the results lack the necessary foundation to be admitted. Judges will evaluate the evidence under Mississippi law, and the result depends on demonstrating that reliability or admissibility is reasonably in doubt given the record.
