Partner | Serious Crime, Terrorism Defence and Professional Discipline Elizabeth Syddall is a Partner at Clifford Johnston & Co and an experienced criminal defence and professional discipline solicitor, specialising in serious and complex criminal investigations, terrorism-related offences, homicide, organised crime and regulatory proceedings. Elizabeth has developed particular expertise in defending individuals facing allegations under terrorism legislation, including the preparation of terrorist acts, suspected involvement in terrorist activity and complex counter-terrorism investigations. Her experience encompasses high-profile and sensitive cases involving national security concerns, extensive digital evidence, online radicalisation and vulnerable defendants. As an accredited duty solicitor, Elizabeth provides strategic advice and representation at every stage of the criminal justice process, from initial police investigation and interview through to Crown Court proceedings and post-conviction matters. Terrorism and National Security Investigations Elizabeth has considerable experience representing clients investigated or prosecuted for some of the most serious offences under terrorism legislation. Her work has included complex prosecutions under section 5 of the Terrorism Act 2006, investigations arising from major terrorist incidents, and allegations involving extremist organisations, online communications and the suspected possession or importation of materials intended for terrorist purposes. These cases frequently involve substantial volumes of digital and forensic evidence, complex questions of criminal intent and significant public and media scrutiny. Elizabeth adopts a meticulous, evidence-led approach, challenging the prosecution's interpretation of material and ensuring that allegations are assessed against the precise legal requirements of the offences charged. She has particular experience representing young and vulnerable defendants, including individuals with mental health conditions or neurodevelopmental disorders, where questions of capacity, susceptibility to influence and online radicalisation require careful consideration. Her terrorism defence work has secured significant outcomes, including acquittals following contested Crown Court trials and investigations concluded without prosecution. Serious and Organised Crime Alongside her terrorism practice, Elizabeth represents clients nationwide in serious and complex criminal proceedings, including murder, manslaughter, serious violence, sexual offences, large-scale drug conspiracies, organised crime and high-value money laundering. She has acted in multi-defendant prosecutions involving organised criminal groups, complex financial investigations and cases requiring detailed examination of extensive evidential material. Elizabeth has particular experience defending clients charged with homicide and serious violent offences, including cases involving defendants with significant psychiatric conditions. Her approach combines thorough preparation, sound tactical judgement and determined representation, with particular emphasis on identifying evidential weaknesses and developing an effective defence strategy. Professional Discipline and Regulatory Law Elizabeth also represents professionals facing disciplinary investigations, allegations of misconduct and fitness-to-practise proceedings that may place their careers, professional registration and reputations at risk. Her regulatory experience includes proceedings involving the Teaching Regulation Agency, General Dental Council, Health and Care Professions Council, and Nursing and Midwifery Council. Her combined expertise in criminal defence and professional regulation is particularly valuable where allegations give rise to parallel criminal and disciplinary proceedings, requiring careful coordination of the client's legal and professional interests. Notable Cases Terrorism — Acquittal Following Crown Court Trial Represented a 19-year-old defendant charged with preparation of terrorist acts contrary to section 5 of the Terrorism Act 2006. The prosecution relied on extensive online communications, ideological material and physical evidence. Following a lengthy trial at Manchester Crown Court, the defendant was acquitted of the section 5 offence. Counter-Terrorism Investigation — No Further Action Represented an individual arrested as part of a major counter-terrorism investigation following a fatal terrorist attack in Greater Manchester. The investigation examined allegations of potential involvement arising from the client's association with another individual. The matter concluded with no further action. Terrorism — Vulnerable Young Defendant Represented a young defendant charged with preparing terrorist acts following alleged online involvement with a proscribed extreme-right-wing organisation. The case involved complex issues of autism, vulnerability, online radicalisation and potential grooming by older extremists. Following a Crown Court trial in which the jury could not reach a verdict, the prosecution elected not to pursue a retrial on the section 5 allegation. Counter-Terrorism — Suspected Importation of Radioactive Material Represented a businessman arrested following the discovery of uranium in materials imported during legitimate commercial activities. The investigation concerned suspicions that radioactive material had been imported for terrorist purposes. Following representations and investigation, no criminal proceedings were brought and the matter concluded with no further action.
