Sector: Police and criminal justice

Interpreting for police and criminal justice

From the custody suite to the courtroom, SILA Linguists provides vetted interpreters and evidential translation that protect the integrity of investigations and the rights of everyone involved.

In England and Wales, police may not interview a suspect who does not appear to speak or understand English unless an interpreter is present, except in tightly defined urgent cases. Across the EU, suspects and accused persons have the right to interpretation and to translation of essential documents. In both systems, poor interpreting can make evidence inadmissible and put a case at risk.

SILA Linguists provides interpreting for custody, interviews under caution, witness and victim statements, and the later stages of a case. Our interpreters are vetted, impartial and familiar with police procedure, including the caution, rights and entitlements, and the requirements for recording interviews conducted through an interpreter. England and Wales and Scotland each have their own procedures, and our interpreters follow the rules that apply.

Investigations increasingly depend on foreign-language material: phone downloads, messaging apps, social media, recorded calls and seized documents. We transcribe and translate this material for evidential use, and our forensic linguists support cases where a speaker's origin or identity is in question.

What this sector needs

Language challenges in police and justice

  1. Interviews under caution

    Interpreters must convey the caution, questions and answers exactly, so that the interview record can be relied on in court.

  2. Custody at any hour

    Detainees arrive day and night. Custody officers need quick access to an interpreter to explain rights and entitlements.

  3. Victims and vulnerable witnesses

    Victims of domestic abuse, trafficking and sexual offences need interpreters who are calm, neutral and, where requested, of a particular gender.

  4. Evidential translation

    Seized documents, messages and recordings must be translated and transcribed in a format suitable for disclosure and court bundles.

  5. Independence from the parties

    Interpreters must not have links to the suspect, victim or community involved, and conflicts must be declared at booking.

  6. Security of material

    Case material must stay inside secure, GDPR-compliant workflows with linguists bound by confidentiality agreements.

Questions

Frequently asked questions

Do your police interpreters work to PACE?

Our police interpreting follows the requirements of PACE Code C in England and Wales, including those for interviews conducted through an interpreter. Scotland has its own procedures, and elsewhere we follow the equivalent local rules.

Can we use telephone interpreting in custody?

Telephone or video interpreting is often suitable for booking-in, rights and entitlements and short contacts. For interviews under caution and complex statements, face-to-face interpreting is usually preferred.

Can you transcribe and translate recordings for court?

Yes. We produce verbatim transcripts with translations, timestamps and speaker labels so that the material can be checked against the original recording.

How do you avoid conflicts of interest?

We ask interpreters to declare any connection with the people or community involved and replace them if a conflict arises. Tell us any concerns when you book.
