KembaraXtra-Case Law- Harvey (1981) CA
Blackmail & Honest Belief
Core Issue: Blackmail under the Theft Act 1968, specifically the requirement of a "demand with menaces" without reasonable cause.

Facts:

D paid S £20,000 for what was believed to be cannabis.
The substance was not cannabis.
D kidnapped S's wife and child.
D threatened rape, maiming, and murder unless S returned the money.
D was convicted of blackmail.
Legal Reasoning:

The Judge directed the jury that threats of very serious offenses could never be considered "proper."
Held (Key Takeaway):

Section 21(1) of the Theft Act 1968 focuses on the individual defendant's honest belief in the situation.
Key Phrase: "honest belief of the individual D"
The objective standard of the "reasonable man" is irrelevant.
Key Phrase: "It does not matter what the reasonable man... would believe"
The defendant's subjective, honest belief is the crucial element.
Key Phrase: "D's honest belief is what matters"
Implications:

This case emphasizes a subjective test for determining the reasonableness of a demand in blackmail cases. The focus is on what the defendant honestly believed, not what a reasonable person would have believed.
