Lesson 1: Introduction: criminal defences

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about criminal defences. Then check against the key terms: GCSE Law Exam Tips — Criminal Defences. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: GCSE Law Exam Tips — Criminal Defences.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: criminal defences. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Law because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: explain the key ideas of criminal defences

Your student states one thing they learned and one question they still have about criminal defences.

Lesson 2: Core Concepts: criminal defences

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on criminal defences. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Defences allow a defendant to avoid criminal liability even if the prosecution has proved actus reus and mens rea
Key Fact: Self-defence is available where the defendant used reasonable force to defend themselves, another person or property
Key Fact: The force used must be proportionate to the threat — excessive force negates the defence of self-defence
Key Fact: Insanity is governed by the M'Naghten rules — the defendant must have a defect of reason from a disease of the mind
Key Fact: Under M'Naghten, the defendant must not know the nature and quality of their act or that it was wrong
Key Fact: Automatism is an act done by the body without the mind's control — it negates actus reus (e.g. sleepwalking, convulsion)

Error Review

Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.

Lesson 4: Exam Practice: criminal defences

Duration: 50 minutes

Starter Activity (5 minutes)

Command Words

Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).

Extended Answer

Extended question: Full-Mark Response How far do criminal defences achieve justice for defendants? (15 marks) <div class="

Criminal defences achieve justice for some defendants by recognising that not all criminal acts deserve punishment, but significant gaps and inconsistencies mean that justice is not always served. Self-defence is an effective defence because it recognises the right to protect oneself and others — the requirement of reasonable force ensures proportionality. However, the test is applied subjectively for the belief and objectively for the force used, which can disadvantage those who genuinely but unreasonably perceive a threat. Insanity, governed by the M'Naghten rules from 1843, is deeply problematic — the archaic language ('defect of reason', 'disease of the mind') is medically meaningless and has led to illogical outcomes where diabetics and epileptics have been classed as insane. The special verdict of 'not guilty by reason of insanity' can result in indefinite hospital detention, which may be more restrictive than a prison sentence — hardly just for a person who was not morally blameworthy. Automatism provides a full acquittal but only where the cause is external, creating an artificial distinction with insanity. Duress recognises that people forced to commit crimes should not al

Exam Tips: Always identify whether the defence negates actus reus or mens rea — or is a general defence | Self-defence is a complete defence — know the two-stage test (honest belief + reasonable force) | The distinction between insanity and automatism turns on internal vs external causes — know this clearly | Duress limitations are a favourite exam topic — know what crimes it cannot be used for | Use case names to support your answers where possible — e.g. M'Naghten for insanity, Palmer for self-defence
Common Errors: ✗ Thinking self-defence allows any level of force ✓ The force must be reasonable and proportionate to the threat — using a weapon against an unarmed attacker may be excessive ✗ Confusing insanity and automatism ✓ Insanity = defect of reason from internal disease of the mind; automatism = external cause making actions involuntary. They have different outcomes (special verdict vs full acquittal) ✗ Saying voluntary intoxication is always a defence ✓ Voluntary intoxication is only a defence to specific intent crimes — it is never a defence to basic intent crimes (e.g. s20 GBH, assault, rape) ✗ Thinking duress is available for all crimes ✓ Duress is not available for murder, attempted murder, or
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how criminal defences connects to another Law topic you have studied
  • Real-world: research one real-world use or example of criminal defences
  • Critical: "What are the limitations of the models used in criminal defences?"
