LEGAL PRINCIPLE: CRIMINAL LAW – Defences – Provocation – Requirement of Suddenness and Cooling Time
PRINCIPLE STATEMENT
Even though the accused set up the defence of provocation, no amount of provocation can excuse homicide or render it excusable except by virtue of section 318 of the Criminal Code which provides: 'When a person unlawfully kills another in circumstances which, but for (he provisions of this section, would constitute murder, does the act which causes death in the heat of passion caused by sudden provocation, and before there is time for his passion to cool, he is guilty of manslaughter only'.
RATIO DECIDENDI (SOURCE)
Per Ogwuegbu, JSC, in Uluebeka v. State (2000) NLC-341999(SC) at p. 9; Paras D–A.
"Even though the accused set up the defence of provocation, no amount of provocation can excuse homicide or render it excusable except by virtue of section 318 of the Criminal Code which provides: 'When a person unlawfully kills another in circumstances which, but for (he provisions of this section, would constitute murder, does the act which causes death in the heat of passion caused by sudden provocation, and before there is time for his passion to cool, he is guilty of manslaughter only'."
EXPLANATION / SCOPE
Section 318 requires that the killing occur in the heat of passion caused by sudden provocation, before cooling time. If there is sufficient interval for passion to cool and reason to return, the defence fails. Provocation does not excuse homicide; it reduces murder to manslaughter only when the killing is immediate, before cooling. The accused cannot delay retaliation. The test is whether a reasonable person would have cooled off in the intervening time. If the accused had opportunity to reflect but still acted, provocation is unavailable. This ensures the defence applies only to genuine, spontaneous reactions.
