Explain custody, interviews and evidence safeguards
Connect detention limits and suspect protections to fairness and the separate rules governing confession or evidence exclusion.
Section Paper 1 · English legal system
Exam scope and assessment notes
AS and full A Level · section 1.2.4. Original educational scenarios about the law of England and Wales, checked on 14 October 2026. Model answers are formative reasoning, not advice about a real dispute, Cambridge marks or predicted grades. Read the exact statute, case and exam-year source where a rule is disputed or changes. A larger annotated authority bank, full unseen papers and specialist law-teacher review remain outstanding.
Before you begin
- Read a short source carefully and separate its rule from the facts
- Explain which element a fact supports and what is still uncertain
Work on paper. Try each question before revealing help, and explain why your method works.

What you will learn
- Explain ordinary PACE detention, rights, interviews, searches and samples
- Distinguish PACE section 76 and section 78 consequences
Use the relevant clock and authority
For ordinary non-terrorism PACE detention before charge, the usual limit is 24 hours from the relevant time, with authorised extensions for qualifying cases: up to 36 hours under the appropriate senior-officer power and further court-authorised detention up to the 96-hour overall limit. These are limits with conditions, not an automatic entitlement to hold every suspect for four days.
The custody officer records and reviews the legal basis and safeguards. Suspects have rights including legal advice and having someone informed, subject to narrowly regulated delay powers. Children under 18 and vulnerable adults need the appropriate-adult safeguards. The appropriate adult supports communication and fairness; that role does not replace a solicitor's legal advice.
Analyse treatment and evidential consequences
PACE and Codes C, E and F regulate detention, questioning and recording; relevant provisions govern station searches, fingerprints and intimate/non-intimate samples with different authorisations and consent rules. Do not assume consent is needed in exactly the same way for every procedure. Interview conditions, breaks, health needs and records affect fair treatment and reliability.
Section 76 concerns confession evidence obtained by oppression or in circumstances likely to render it unreliable under its tests and burden. Section 78 gives the court a fairness-based discretion to exclude prosecution evidence considering how it was obtained. A breach matters, but does not mean automatic exclusion of all evidence in every case. Apply the relevant provision and explain the effect of the particular defect.

Pause and explain
Is 96 hours the ordinary automatic detention period for every PACE suspect?
Worked example
An ordinary non-terrorism suspect is held for 40 hours without any stated extension authority. A note says this is allowed because the maximum is 96 hours. Assess.
Show the worked solution
- Start with the ordinary 24-hour limit and relevant time.
- Extensions require their own conditions and authority.
- The outer maximum is not a blanket permission.
Answer The note is wrong. A 96-hour outer limit does not authorise forty hours without the required extension process. The analysis must check the relevant time, qualifying conditions, authorisations and review safeguards.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Explain the defect in relying only on the 96-hour maximum.
Give me a hint
An outer cap is different from a power to extend.
Compare my reasoning
- The ordinary clock must be identified.
- The extension route needs authority.
- The maximum cannot replace those steps.
The maximum caps properly authorised detention; it does not supply missing authority. The forty-hour example therefore needs the relevant extension conditions and decisions, not merely a comparison with ninety-six.
Look for these in your work
- Distinguishes cap and authority
- Identifies the missing process
- Uses the stated ordinary regime
Independent: A fictional 16-year-old suspect has an appropriate adult but no explanation of legal-advice rights. Is the adult's presence enough to settle all safeguards?
Give me a hint
The roles have different functions.
Compare my reasoning
- An appropriate adult supports welfare and communication.
- Legal advice is a separate right and professional role.
- The detention/interview safeguards must each be checked.
No. The appropriate adult does not replace legal advice or establish compliance with every detention and interview rule. The answer must examine the separate rights, information and any legally justified delay rather than treating one safeguard as the whole process.
Look for these in your work
- Distinguishes roles
- Preserves separate rights
- Checks the full process
Application: A confession is challenged as obtained through oppressive questioning, and other evidence is challenged as unfairly obtained. Which provisions need separate analysis?
Give me a hint
Confession and general evidence rules differ.
Compare my reasoning
- Apply section 76's confession tests and burden.
- Apply section 78's fairness discretion to prosecution evidence.
- Explain the effect of the actual circumstances.
Section 76 addresses the challenged confession through its oppression/reliability tests, while section 78 supplies a distinct fairness-based exclusion discretion. The analysis must use the relevant circumstances; neither label alone establishes the result for all evidence.
Look for these in your work
- Identifies both provisions
- Distinguishes their tests
- Avoids automatic exclusion
Common mistakes
- Treating 96 hours as the default period
- Confusing an appropriate adult with a lawyer
- Treating every breach as automatic exclusion
What can you explain now?
Is 96 hours the ordinary automatic detention period for every PACE suspect?
Compare with the explanation
No, authorised extensions and conditions are required
The ordinary limit and each extension must be justified under the applicable scheme.
