Forensic Evidence

Forensic evidence under the Director of Public Prosecution’s Guidance on Charging 2020

The Director of Public Prosecution’s Guidance on Charging (31st December 2020) provides a clear structure in which criminal allegations are investigated and prosecuted. Defence teams must have a detailed working knowledge of the Guidance as part of a proactive pre-charge engagement strategy.

The significance of the Guidance for defence teams

The Olliers Investigations Team place huge emphasis in monitoring the police and their compliance with the Guidance as part of our proactive approach to pre-charge work.

We look to engage with police at an early stage of an investigation. We always consider whether we can make representations against charge, by arguing that there is not a ‘realistic prospect of conviction’ or that it is not in the public interest to prosecute. The Guidance was published on the same day (31st December 2020) as the arrangements for ‘pre charge engagement’ (Annex B Attorney General’s Guidelines on Disclosure 2020).

Director of Public Prosecutions Max Hill QC; 

‘There has been a major shift in working practices and priorities throughout the criminal justice system in recent years and it is vital there is clear guidance to help police and prosecutors navigate these effectively.

‘The Attorney General’s guidelines focus on getting disclosure right and getting it done early so its impact on the evidence is known. These are significant changes and we must continue to work collaboratively to embed them.’

At Olliers we regard the Guidelines as a powerful resource during the pre-charge engagement process.

Pre-charge relevance of Forensic evidence in a criminal investigation 

At Olliers our Investigations team appreciates the potentially huge significance of forensic evidence during the investigation stage of a case.

Key Principles

Forensic evidence is evidence obtained by scientific methods, its significance will vary from case to case.

The impact of forensic evidence must be assessed before a charging decision is made (Full Code Test). In Threshold Test cases an informed decision should be made about the likely impact of forensic evidence.

Use of Streamlined Forensic Reports (SFRs) is encouraged. SFRs may cover fingerprint evidence, data/digital downloads, data material, DNA evidence, drugs, footwear, marks and traces, firearms and toxicology.

An SFR1 is a summary of the forensic evidence that is served on the defence to ensure that they are aware of the nature of the evidence and web evidence and where possible to secure an admission as to contents. It must contain sufficient detail for the defence to make the admission.

Information sent to the prosecutor should provide context such as location of recovered evidence and its significance. The prosecutor should also be informed about any other findings, such as DNA/fingerprints, which do not relate to the suspect, and their attribution, crime scene/exhibit photography should be provided if available. If a stage 1 SFR is not admitted, a stage 2 SFR may be required.

If the case proceeds to trial and the matter is complex or elements of the SFR are challenged then a full evidential statement will be required.

Controlled substances

If the case involves controlled substances and identification is challenged, further evidence will be required after charge. Investigators and prosecutors should have regard to up-to-date guidance in relation to the admissibility of the evidence.

Case progression

SFRs should be available both for charging purposes and as part of the Magistrates’ Court Initial Details of the Prosecution Case (IDPC). Delay may have an adverse impact on evidence being agreed and early guilty pleas.

In all cases the prosecution should be aware of the existence of forensic evidence and the stage reached in terms of preparation of reports etc. A proactive approach is required in custody cases due to custody time limits.

Unused material

The CPIA Code of Practice should be complied with. Full and accurate records must be maintained for scene examinations and these must be available for the disclosure officer. Where forensic analysis are negative and point away from the suspect or towards another individual, this must be communicate to the prosecutor as soon as possible (defence practitioners should be particularly alert to this issue).

The Guidance recognises ‘the overarching principles’  set  out  in  Sir  Brian  Leveson’s review of ‘Efficiency in Criminal Proceedings’, the most important of which is perhaps the concept of ‘getting it right first time’

Police officers and prosecutors must comply with this Guidance to ensure that charging  decisions  are  fair  and  consistent,  and  comply with the Police and Criminal Evidence Act, the PACE Codes of Practice, and the Code for Crown Prosecutors (“the Code”). As the police get to grips with the Guidance it is inevitable that mistakes will be made. Failure to follow the Guidance may risk cases failing or decisions being subject to legal challenge.

The guidance is issued by the DPP for police use, but the provisions apply equally to other investigators where cases are prosecuted by the CPS

At Olliers we recognise the importance of defence teams being at least as familiar with the obligations upon the police as are their police counterparts.

Case Studies

Case Study One
21-year-old male of good character faced allegation of date rape in which the complainant claimed to have been unconscious for ten hours. Olliers were able to prove social media activity throughout the night and downloading of an app together with text activity from the alleged victim the following day. Olliers also provided police with details of a flatmate who witnessed sexual activity. Police were also provided with a motive for the fabricated complaint. Following representations to the police, matter came to a swift conclusion without even going to the Crown Prosecution Service for a charging decision.

Case Study Two
Young man faced allegation of sexual assault in a nightclub. It was suggested that he had assaulted a complete stranger without any earlier interaction. Olliers were able to show that alleged victim had in fact connected with the suspect on WhatsApp at the time of the incident which would have been impossible on her version of events. Olliers were also able to show that complainant’s boyfriend had unexpectedly arrived in the nightclub which gave an explanation and motive for the false allegation. No charges were brought.

Case Study Three
Client faced an allegation of historic rape based upon one incident thirty years earlier. Olliers were able to produce to the police a poem sent to the defendant by the complainant ten years previously i.e. twenty years after the alleged incident in which she admitted to her infatuation with the suspect at the time of the incident. Representations were made including a defence explanation for the allegations being made.  Crown Prosecution Service took the view that there was not a realistic prospect of conviction and no charges were brought.

Case Study Four
Client  was arrested and interviewed under caution in connection with historic allegations of rape. He was subsequently released under investigation pending further police enquiries. On contacting Olliers, we immediately adopted a proactive approach and established contact with both the officer in the case and the duty solicitor who had represented the client at the police station. Following detailed consideration of the police station notes, and on taking thorough instructions from our client, we drafted representations against charge on his behalf. The aim of our representations was to persuade the Crown Prosecution Service that there was ‘not a realistic prospect of conviction’ as required by the Code for Crown Prosecutors. The police investigation was ongoing for some time and we periodically liaised with the investigating officer to provide the client with updates. Having considered our representations, the police decided to take no further action against our client and the matter came to a close.

Case Study Five
Our client was arrested and interviewed under caution in relation to historic allegations of rape, sexual assault and controlling or coercive behaviour. He was subsequently released under investigation pending further police enquiries. The client contacted Olliers shortly after his arrest. Following this, we obtained the case papers from the duty solicitor who had represented him during interview. We also established contact with the investigating officer and drew their attention to some initial points about the case which would require further investigation. As the investigation developed, we drafted comprehensive representations against charge based on our client’s detailed instructions and relevant material he had provided. On considering our representations, the police decided to take no further action against our client and the matter was concluded.

Case Study Six
Our clients were directors of a payment processing company. This was a multi-jurisdictional investigation involving restraint of assets on several continents. Extensive police liaison took place, a substantial amount of exculpatory material was provided to the police. Complex and ultimately successful applications to vary and discharge restraint orders were made. Representations against charge were submitted. The matter concluded following a successful application under the Criminal Justice and Police Act 2001 for return of items unlawfully seized by police and decision was made to take no further action against our clients.

Case Study Seven
Client E was arrested and interviewed under caution concerning allegations of rape and sexual assault. He was released under investigation as the police continued with their enquiries. Client E contacted Olliers only a few days following his arrest to request pre-charge representation. We swiftly proceeded to make contact with the investigating officer to establish a line of communication. We also quickly obtained the case papers from the duty solicitor whom represented Client E at the police station. For the following five months, we maintained contact with the investigating officer and regularly liaised with them regarding bail requirements and the progress of their investigation. After in-depth consideration of the police station notes and all of the information and instructions provided by the client, we disclosed some material to the investigating officer concerning the allegations. Following review by the police and consideration of their lines of enquiry, a decision to take no further action was reached thereby concluding the investigation.
