Inchoate offences & parties
Inchoate offences criminalise conduct before the full crime is completed, while the rules on parties (accessorial liability) determine who besides the principal is liable. Both extend criminal responsibility beyond the direct perpetrator.
What "Inchoate offences & parties" covers
- Attempt (s.1 Criminal Attempts Act 1981): an act more than merely preparatory to the offence, with intent to commit it (Gullefer; Geddes on the more-than-merely-preparatory line).
- Attempt requires intent even where recklessness suffices for the full offence; attempting the impossible is still an attempt (s.1(2)-(3); Shivpuri).
- Conspiracy (s.1 Criminal Law Act 1977): an agreement between two or more that a course of conduct will be pursued which will necessarily amount to an offence; the agreement itself is the crime.
- Encouraging or assisting crime (ss.44-46 Serious Crime Act 2007) replaced common law incitement; the offence is complete on the act of encouragement/assistance regardless of whether the offence occurs.
- A principal offender directly commits the actus reus; an accessory aids, abets, counsels or procures the offence (s.8 Accessories and Abettors Act 1861).
- Accessorial liability requires the accessory to intend to assist/encourage and to know the essential matters of the principal's offence (Jogee restored intention as the fault element for secondary liability).
- Withdrawal from participation may negate liability, but generally requires timely and (for spontaneous violence) unequivocal communication of withdrawal.

How it's tested in SQE1
SQE1 uses single best answer questions: a short factual scenario, one precise question, and five options of which only one is the best answer on the law applied to the facts. For inchoate offences & parties, expect to be asked what the correct legal position is, what a party may or must do, or which outcome follows — with more than one option looking arguable. Reading the facts carefully and eliminating the near-misses is the skill that earns the mark.
Where candidates lose marks
- Applying the old 'parasitic accessory liability' foresight test — R v Jogee held foresight is only evidence of intent, not a substitute for it.
- Thinking attempt can be committed recklessly — it requires intention to commit the substantive offence.
- Assuming impossibility is a defence to attempt or conspiracy — under statute it generally is not (Shivpuri).
