Study Notes
Parties to a Crime/Complicity
- D's liability derives from proof of the principal offense, not from P's conviction for it
- D's liability depends on proof that their acts were relevant to a principal offense that has been committed by another party
Uncertainty: Principal Offenders and Accomplices
- Legal uncertainties: separating principal offenders and accomplices can emerge in cases of innocent agency
- Factual uncertainties: factual problems separating principal offenders and accomplices can emerge in cases where D's role in the principal offense is unclear
Complicity by Aiding, Abetting, Counselling, or Procuring
- D is labelled and punished as if they committed the principal offense
- Cases begin by identifying the crime that P has committed, and then discuss D's actus reus and mens rea in relation to that principal offense
Actus Reus of Aiding, Abetting, Counselling, or Procuring
- D's conduct only needs to satisfy one of these terms to complete the actus reus
- Aiding: assisting at the time P commits the principal offense or in advance of the offense
- Abetting: encouraging, including instigating or emboldening, or discouraging by threatening
- Counselling: encouraging, including instigating or emboldening
- Can D assist or encourage by omission? Yes, in certain circumstances
Must D Cause P's Offense?
- No casual link is necessary for inchoate assisting or encouraging
- D's liability in complicity derives from P's completion of a crime
Principal or Accomplice
- D as a principal offender: completes the AR and MR elements of the principal offense
- D as a coprincipal: each actor completes the AR and MR of the offense
- D as a principal via innocent agency: uses a party as a tool to commit an offense, and that party is unaware of the circumstances that would make their acts criminal
- D as an accomplice: aids, abets, counsels, or procures P to commit the offense and P does so
Mens Rea of Aiding, Abetting, Counselling, or Procuring
-
D's MR as to her own conduct: voluntarily performing the actus reus, and intending to assist or encourage P
-
D's MR as to the principal offense: intending that P will commit the offense and knowing the essential elements of P's offense### Omission to Secure Escape (OSE)
-
No OSE where P's change of target is unintentional
-
P's mens rea (intention to kill X) is transferred to V if P attempts to kill X but accidentally kills V
-
Same is true for D: her mens rea (intention of P killing X) is also transferred to V
Qualifications for OSE
- No OSE if the change is insubstantial
- Unlikely to be an OSE where P carries out the principal offence as planned and goes on to commit an additional event of the same type
OSE and Factual Differences
- Factual differences that break the nexus of responsibility between D and the principal offence may establish an OSE
- P acting in a considerably more dangerous way than that intended by D may be a basis for establishing an OSE
Joint Enterprise Liability
- Joint enterprise liability is a separate route to complicity
- Involves a coordination of behavior between D and P towards a common criminal end
- D is liable for Crime B if D had foreseen as a possibility that P might commit it with MR, and the manner in which P did so was not fundamentally different from what D had foreseen might happen
Complicity and Inchoate Liability
- D may be complicit in inchoate offences such as conspiracy to rape or assisting murder
- D assists, encourages, or procures the inchoate offence, and P goes on to commit that inchoate offence
Defences
- General defences and denials of offending apply to complicity as all other criminal offences
- Withdrawal: D cannot negate inchoate liability if she later withdraws by removing or renouncing her assistance or encouragement
- However, if D successfully withdraws in time, D will be able to limit her liability to the inchoate charge and avoid complicity liability
The Victim Rule
- Applies to offences designed to protect a specific class of victim
- Someone within that class is not complicit where they assist, encourage, or procure the offence to be committed against themselves
- Defence will not apply to D within the protected class if she assists or encourages P to commit the offence against another person within that class
