Conspiracy to murder

Conspiracy to murder is a statutory offence defined by the intent to commit murder.

England and Wales
The offence of conspiracy to murder was created in statutory law by section 4 of the Offences Against the Person Act 1861 and retained as an offence by virtue of section 1(1) of the Criminal Law Act 1977.

Mens rea: Although an intention to cause grievous bodily harm is sufficient for murder, it is not sufficient for conspiracy to murder.

Jurisdiction
Section 1(4) of the Criminal Law Act 1977 formerly provided that it was immaterial that the murder in question would not be triable in England and Wales if committed in accordance with the intention of the parties to the agreement. This reproduced the effect of section 4 of the 1861 Act.

See now section 1A of the Criminal Law Act 1977.

Sentence
A person guilty of conspiracy to murder is liable to imprisonment for life or for any shorter term.

As to the maximum sentence in a case where the agreement was entered into before Part I of the Criminal Law Act 1977 came into force, see section 5(5) of that Act.

See the Crown Prosecution Service sentencing manual.
