prosecution case.

alleged offence details (their version of events, substantive law, what police will
need to prove), client instructions, next steps.
Interview Prep:
o Options: answer all questions, no comment, selective silence, or written
statement on client’s behalf.
o Safest option depends on case strength, disclosure, and client
vulnerability.
Client's Interview Options
1. Answer All Questions:
o Pros: Puts version on record, important if raising specific defence, avoids
adverse inferences (CJPOA 1994), no previous convictions and admits
guilt- may get caution instead of charge, can tell court C co-operated and
saved time/money
o Cons: Risk of self-incrimination, credibility harm if flustered, confusion,
caught out if matter raised not disclosed to solicitor, attack on other’s
character
2. No Comment:
o Pros: Avoids incrimination, weak case- insufficient evidence
o Cons: Adverse inferences under CJPOA 1994 if charged and pleaded not
guilty
o Likely to be advised to give this when: inadequate disclosure of evidence
(and C denies involvement), physically/mentally unfit, elderly, immature,
complex/old facts, claims not to be guilty without viable case or defence,
good personal reasons (e.g. embarrassment)
3. Selective Silence: Risky—implies hiding something.
4. Prepared Written Statement:
, CRIMINAL PRACTICE NOTES
o Use if defence details are clear, to avoid adverse inferences.
o Set out facts they intend to rely on at trial
o Hand statement to the police just prior to charge or kept on client’s file
and not disclosed (especially if doubt)
o Normal to hand in at the start and answer no comment
o Will not prevent adverse inferences- C was not confident defence could
live up to scrutiny and not thought up all the details of this defence at the
time of the interview
