Dealing with Speech, Language and Communication Needs (SLCNs) can be a challenge for anyone, but for those in the criminal justice system (CJS) it can make the difference between being able to access support they are entitled to, or being unfairly discriminated against.

No research seems to have been conducted on defendants who specifically stammer within the CJS, but approximately ‘60%’ of people in the Youth Justice System and ‘80%’ of adults in a prison have been described as having SLCNs. We also know that ‘1-3%’ of the adult population stammer. It is therefore possible that many defendants are living with the impact of a stammer when pursuing their own defence at trial and experiencing a lack of support from the CJS and laws which support it.

Research by the Prison Reform Trust has highlighted the significant communication demands of the CJS. Everyone living with a stammer is unique, and there are of course people with whom the following will not resonate, but in our experience, people may recognise some of the following, which could significantly contribute to their vulnerability within the CJS:

  • Feeling ‘silenced’, finding it challenging to explain themselves optimally, or elaborate, clarify and ask questions.
  • Fear of speaking/ avoiding speaking.
  • Experiencing stigma and stereotyping around issues like intelligence, nervousness and trustworthiness.
  • Shame around speaking leading to reduced confidence, especially in public situations.

We argue that the law needs reforming and enforcing, to improve the support and assistance available to people who stammer as they navigate around and negotiate with the CJS. There are barriers to justice: including an increased risk of compromised liberty, dignity, and unfair sentencing, for people who stammer. Defendants need to contest the ‘legal burden of proof’ (i.e. being the ‘presumed innocent until proven guilty’ principle). Having a stammer can increase the challenges of self- expression, making this a more daunting and overwhelming experience compared to those who do not have SLCNs.

For example:

We suggest ways that SLT can help:

  • In SLT, disclosure of having a stammer or ‘advertising’ can be part of de-sensitisation. ‘Disclosure’ could involve explaining to the court the impact a stammer could have on them and for this to be taken into account.  
  • Improved and urgent access to a specialist SLT before court appearances is important. Currently, this is not easy in many parts of the UK.
  • Training/workshops for CJS staff and legal professionals
  • Support for compulsory screening of speech issues, not just for young offenders. Speech issues need to be dealt with on a par with how mental health is viewed and managed in court. Stammering and other SLCNs need to be recognised as something the court needs to accommodate for, by law.

Although we may be talking about small numbers, it is our hope that no person who has a stammer will be disadvantaged by it in court, as a victim, witness or defendant.

Esther Pritchard is a Law with Criminology graduate from the University of Sheffield, who also stammers and is currently working in the legal banking sector in New Zealand. She has conducted research which discusses how criminal procedures, especially around the availability of special measures for defendants, impacts upon the ability of defendants with a stammer to adequately pursue their own defence in trial.
