What does a blood alcohol expert witness do?
A blood or breath alcohol expert witness provides independent expert reports for legal cases, particularly drink driving investigations.
Can blood or breath alcohol test results be challenged in court?
Yes. An expert can review laboratory procedures, sample handling, and the interpretation of results to determine whether the evidence is scientifically reliable.
When is blood and breath alcohol analysis used in legal cases?
Blood alcohol analysis is commonly used in drink driving prosecutions and other investigations where alcohol consumption may be relevant to the circumstances of an incident.
• Laced or Spiked Drinks Cases ("Back Calculations")
Could your drink have been unknowingly spiked with alcohol? We provide expert forensic analysis to determine if additional alcohol was present.
• Post-Incident Alcohol Consumption ("Hip Flask" Defence)
Did you consume alcohol after driving but before the police arrived? Our calculations help determine if this affected your test results.
• Drunk in Charge Cases
Need to establish when you would have been under the legal driving limit? We perform precise time-based alcohol calculations to support your case.
• Medication & Medical Conditions Impact
Certain medical conditions or medications can affect alcohol test results. Our expert reports analyse whether these factors played a role in your case.
• Roadside & Evidential Breath Testing Procedures
Was the breath test carried out correctly? Our experts review police procedures and breath test instruments (Intoxilyzer, Intoximeter, Camic) to check for errors in calibration or use.
