R v Beedie (1996)

The tenant of a property died of carbon monoxide poisoning caused by the use of a defective gas fire. The landlord was prosecuted and pleaded guilty to an offence under the Health and Safety at Work etc. Act 1974 arising from a breach of the duty to ensure that the appliance was maintained and repaired. He was fined £1,500.
He then pleaded guilty as manager of the premises to an offence under the Housing Act 1985 in relation to other gas installations at the same premises. He was granted a conditional discharge.
The following year he was charged with manslaugter. The judge rejected his application to halt the proceedings, so the landlord pleaded guilty.

On appeal:
HELD: The Court of Appeal quashed his appeal because the manslaughter charge had been based on substantially the same facts as the earlier prosecutions, which is considered ‘double jeapardy’ and not allowed by the English legal system.
