SQE1 Criminal Law: Complete Guide
Candidates often lose marks on SQE1 Criminal Law by focusing on offence names rather than mastering the foundational distinction between actus reus and mens rea — the two-element framework that examiners test across every scenario. This guide shows you the systematic approach that rewards precision.

What Is Criminal Law?
Candidates frequently lose marks on SQE1 Criminal Law questions by failing to apply both actus reus and mens rea systematically — examiners test this foundational requirement across virtually every criminal topic.
Within SQE1, Criminal Law is tested as part of FLK1. The exam focuses on the substantive law — the definitions of offences and defences — rather than criminal procedure (which is covered separately under Criminal Practice). You need to be able to identify the correct offence on the facts, determine whether the required mens rea is established, and assess whether any defence applies. The precision demanded by scenario-based questions makes this one of the subjects where targeted MCQ practice has the greatest impact, particularly when distinguishing between homicide categories.

Key Principles for SQE1
Exam tip
Criminal Law rewards systematic, element-by-element analysis — break down every offence into actus reus, mens rea, and any additional requirements. Distinguish between the levels of non-fatal offence (common assault, s.47 ABH, s.20 GBH with recklessness, s.18 GBH with intention) based precisely on the harm and mental state. For defences, identify which apply to which offences (e.g., intoxication works differently for specific vs basic intent crimes). The difference between correct and incorrect often hinges on one factual detail: whether harm was intended or merely reckless, or whether the defendant's liability was primary or secondary.
How This Appears in SQE1 Questions
This is one of the most commonly tested areas in SQE1 — examiners regularly combine multiple criminal law principles in a single scenario. Criminal Law is assessed as part of FLK1 using single-best-answer questions with five options (A–E). Questions are scenario-based: you will be given a set of facts describing an incident and asked to identify the most appropriate offence, whether liability is established, or which defence is most likely to succeed. This is a classic SQE1 assessment structure that rewards precise element-by-element analysis.
Distractors are carefully designed. A common pattern is to present answer options that identify the correct area of law but apply the wrong offence level — for example, offering section 20 GBH when the facts support section 18, or suggesting murder when the scenario includes evidence supporting a loss of control defence. Other distractors may state the correct offence but misidentify the mens rea requirement.
Careful reading is critical. The difference between a correct and incorrect answer often turns on a single factual detail — such as whether the defendant intended serious harm or was merely reckless.
Common Mistakes Students Make
- Distinguishing between levels of non-fatal offence
- The boundaries between section 47, section 20 and section 18 are tested heavily. Candidates often select the wrong offence because they misjudge the level of harm or confuse the mens rea requirements — particularly the difference between intention and recklessness for GBH offences.
- Identifying the correct type of manslaughter
- Unlawful act manslaughter, gross negligence manslaughter and the voluntary manslaughter defences each have distinct elements. Scenarios may contain facts that engage more than one route, and candidates need to determine which applies on the specific facts given.
- Applying the intoxication rules
- The distinction between specific intent and basic intent offences, and between voluntary and involuntary intoxication, creates a matrix that many candidates find difficult to navigate under timed conditions.
- Handling questions with overlapping offences and defences
- Exam scenarios are often designed so that multiple offences or defences appear arguable. The skill the exam rewards is selecting the best answer — not just a plausible one — which requires careful analysis of every element.
Quick Summary
- Actus reus and mens rea are the two essential elements of criminal liability. Actus reus is the guilty act (acts, omissions or states of affairs); mens rea is the guilty mind (intention, recklessness or negligence).
- Fatal offences range from murder (intentional or reckless killing) to voluntary manslaughter (diminished responsibility or loss of control) to involuntary manslaughter (unlawful act or gross negligence).
- Non-fatal offences form a hierarchy: common assault, section 47 ABH, section 20 GBH (recklessness), section 18 GBH (intention).
- Property offences include theft (dishonest appropriation with intent to permanently deprive), robbery, burglary, fraud and criminal damage.
- Defences such as self-defence, intoxication, duress and necessity may excuse or justify otherwise criminal conduct, but their availability depends on the type of offence and the circumstances.

Question 1
Scenario
Two friends, a mechanic and a shop assistant, agree to burgle a warehouse on an industrial estate at night. They plan to steal computer equipment stored inside. The mechanic will drive the van and act as lookout outside while the shop assistant enters the warehouse through a window to collect the items. On the night of the planned burglary, the mechanic drives the shop assistant to the warehouse as agreed. The shop assistant climbs through an open window and enters the warehouse. Once inside, the shop assistant finds the warehouse manager asleep in a back office. The shop assistant had not expected anyone to be present. The shop assistant picks up a metal bar and strikes the warehouse manager on the arm, breaking it, to prevent the manager from calling the police. The shop assistant then takes three laptop computers and returns to the van. The mechanic sees the shop assistant return with the laptops but does not know about the assault on the warehouse manager. The mechanic had explicitly told the shop assistant before the burglary that no violence should be used under any circumstances. The pair drive away and are arrested the following day. The warehouse manager requires surgery for the broken arm.
Is the mechanic likely to be criminally liable for the assault on the warehouse manager?
Question 2
Scenario
A man stabs his neighbour in the abdomen during an argument over a parking space. The neighbour is taken to hospital by ambulance. At hospital, the neighbour undergoes surgery to repair the stab wound. The surgery is performed competently and is initially successful. Two days after the operation, the neighbour develops a blood clot in his leg. The blood clot is a recognised complication of abdominal surgery and occurs despite appropriate post-operative care. The clot travels to the neighbour's lungs, causing a pulmonary embolism. The neighbour dies as a result. Medical evidence confirms that the pulmonary embolism was caused by the blood clot, which developed as a direct consequence of the surgery required to treat the stab wound. The man is arrested and charged with murder. He argues that it was the blood clot, not the stabbing, that killed the neighbour. The man had previously quarrelled with the neighbour on several occasions about the parking space.
Is the prosecution likely to establish that the man's act of stabbing caused the neighbour's death?
Question 3
Scenario
A man is employed as a night-time security guard at a construction site. His duties include patrolling the site perimeter, checking access points, and reporting any suspicious activity. The site contains heavy machinery and open excavation pits that are fenced off but not covered. One evening, the guard notices that a section of fencing around an excavation pit has fallen over, leaving the pit exposed. He considers re-erecting the fence but decides it is 'not his job' to perform maintenance work and continues his patrol. He does not report the fallen fence to anyone. Later that night, an intruder climbs over the site boundary and falls into the exposed pit, suffering serious spinal injuries. The intruder was attempting to steal copper wiring from the site. The guard was on the opposite side of the site at the time and was unaware of the intruder's presence. The construction company's health and safety policy requires security guards to report any hazard identified during patrols. A solicitor advising the guard considers whether the guard's failure to report could also amount to a breach of regulatory duties, and whether the solicitor can advise both the guard and the construction company on the matter.
Which of the following best describes the guard's potential criminal liability for the intruder's injuries?
