Protection Of Vulnerable Witnesses
1. Introduction
Vulnerable witnesses are individuals who may be particularly susceptible to intimidation, trauma, or manipulation during legal proceedings. They include:
Children
Victims of sexual offences
Individuals with mental disabilities or learning difficulties
Individuals with significant fear of the accused
The law recognizes that these witnesses may require special measures to give evidence safely and effectively.
The aim is to ensure justice while minimizing additional trauma to the witness.
2. Legal Framework
Protection of vulnerable witnesses is governed by:
Youth Justice and Criminal Evidence Act 1999 (UK) – Introduced “special measures” for vulnerable witnesses.
Criminal Procedure (Attendance of Witnesses) Act 1965 – Related to witness summoning.
Common Law Protections – Courts have inherent jurisdiction to protect witnesses from intimidation or harm.
Special Measures Include:
Screening from the accused – Physical barriers or separate rooms.
Live link evidence – Giving testimony via video.
Removal of wigs and gowns – Reduces intimidation.
Use of intermediaries – Professionals who help communicate with witnesses.
Evidence in private – Excluding the public from court.
Pre-recorded evidence – Especially for children or vulnerable adults.
3. Key Principles
Fair Trial vs Witness Protection: Must balance protection of witnesses with the accused’s right to a fair trial.
Early Identification: Vulnerable witnesses should be identified early to plan special measures.
Court Discretion: Judges have discretion to authorize appropriate protections.
Minimizing Trauma: Measures aim to prevent retraumatization during testimony.
