R v Calhaem [1985] QB 808
Facts
Calhaem instructed another person, Z, to kill the victim. Z carried out the killing but claimed that he had initially decided merely to frighten the victim and then lost control during the encounter. Calhaem was prosecuted as a secondary party who had counselled murder. She argued that the prosecution needed to prove a substantial causal connection between her counselling and the eventual killing, and that Z's account broke that connection. Her conviction therefore raised the meaning of counselling under section 8 of the Accessories and Abettors Act 1861.
Legal Issue
Does liability for counselling require proof that the instruction was a substantial cause of the completed offence, or can it arise where the person counselled commits the offence within the scope of the instruction?
Held
The Court of Appeal dismissed the appeal. Counselling was given its ordinary meaning, including instructing or encouraging another person to commit an offence. It did not require the additional substantial causal connection for which Calhaem argued. The principal had committed the contemplated murder within the scope of the counselling, rather than causing the death by an unrelated accident. Z's asserted change of mind about his motivation therefore did not necessarily defeat Calhaem's liability. The decision does not dispense with the secondary party's required state of mind or make any earlier contact sufficient. The counselling must relate to the offence committed and satisfy the applicable requirements of complicity.
⭐ Legal Principle
Counselling an offence does not require proof that the counselling was a substantial factual cause of its commission. Liability may arise where the person counselled commits the offence within the scope of the instruction or encouragement, subject to the required mental element.
Significance
The case helps distinguish the conduct requirements of different forms of secondary liability. In particular, counselling should not be treated as identical to procuring, where a causal connection has a different role. For a modern analysis, read the case with R v Jogee [2016] UKSC 8 on intentional assistance or encouragement and the insufficiency of foresight alone. A defendant's association with the principal is not a substitute for identifying the relevant counselling and intention.
Common exam questions about this case
Why did Z's stated change of plan not necessarily defeat liability?
The relevant murder remained within the scope of the counselling. The prosecution did not have to establish that Calhaem's instruction was the substantial factual cause of Z's eventual decision to kill. His account of a change in motivation therefore did not itself dispose of her liability.
Does Calhaem remove the need for mens rea?
No. It addresses the causal requirement associated with counselling, not an exemption from proving the secondary party's state of mind. Modern analysis must take account of Jogee: intentional assistance or encouragement is required, and foresight that the principal might offend is not sufficient by itself.
Why compare counselling with procuring?
Different forms of secondary participation should not be collapsed into one test. Calhaem rejects an additional substantial-causation requirement for counselling, while procuring involves bringing about the offence. An answer should identify the alleged form of participation and apply its requirements to the evidence rather than relying on association alone.
