Holding

The Court of Appeal allowed the appeal against a manslaughter conviction. The appellant, a trained native dresser, administered a bismuth injection that resulted in death. He measured the dosage using closed scissor blades in the absence of scales, a method he had been told was acceptable. The evidence did not disclose beyond doubt that the appellant was guilty of such negligence as to show a criminal disregard of human life.

Outcome

Conviction quashed

Facts

The appellant was a trained native dresser employed on a sisal estate in Tanganyika. He gave an injection of bismuth sodium tartrate to a native employee of the estate. The native subsequently died of bismuth poisoning. The maximum safe dosage for the drug was three grains. The appellant intended to inject half a grain but had no scales available, so he estimated the dosage by measurement with the closed blades of a small pair of scissors. He had been informed by Dr. Chiltern that this was an acceptable method in the absence of scales. The appellant had requested scales from his employers without success. After the death, Dr. Burfield asked the appellant to demonstrate his measuring method, and the quantity measured on that occasion weighed six grains. Medical evidence established that a medical dresser should be capable of giving a bismuth injection and that such training was expected of a dresser on a sisal estate. No post-mortem examination was conducted.

Issues

  1. Whether the manner in which the appellant measured the drug showed such a disregard of human life as to amount to the offence of manslaughter.

Orders

  • Appeal allowed.

Rules and key headnotes

Manslaughter — Criminal Negligence — Standard of Proof
For a conviction of manslaughter based on criminal negligence, the evidence must disclose beyond doubt that the accused was guilty of such negligence as to show a criminal disregard of human life.
Manslaughter — Medical Negligence — Error of Judgment Distinguished from Criminal Negligence
Where a trained medical dresser uses an improvised but previously sanctioned method of measuring medication in the absence of proper equipment, and has unsuccessfully requested such equipment from his employers, an error in dosage does not necessarily constitute criminal negligence amounting to manslaughter.
Criminal Cases — Sufficiency of Evidence — Post-Mortem Examination
The absence of a post-mortem examination and the failure to exhibit physical evidence in court may render the evidence unsatisfactory for establishing criminal negligence beyond reasonable doubt.
