Serious Violence

From privately-instructed Magistrates’ Court trials for battery to the most serious offences of s18 grievous bodily harm and attempted murder, violent crime remains a staple of Jane’s practice. She has also developed a specialism in prosecuting allegations involving parents or other caregivers accused of causing or allowing serious injury to children.

With experience ranging from successfully applying to read the complainant’s statement as hearsay in prosecutions for domestic violence, to persuading a reluctant judge not to send her university student client to prison, Jane is adept at all aspects of advocacy in every kind of violent crime.

Jane is highly skilled in the essential elements of a fraud practice – she is able to marshal large amounts of evidence, distil it into a workable and comprehensible form and home in on the key issues.

She has advised on the impact of property freezing orders, restraint orders, management receivership orders and confiscation orders upon the recovery of debt by a local authority. She has drafted s17 POCA defendant’s responses and has also represented clients in contested cash forfeiture proceedings.

Healthcare Regulation

A large part of Jane’s practice is dedicated to regulatory work in Healthcare Regulation and in criminal regulatory cases. She has an impressive ability to master even the most technical of concepts, which has stood her in excellent stead when presenting allegations of clinical misconduct against a doctor, understanding clinical allegations made against her registrant clients, cross-examining experts of all specialisms, and, in one instance, constructing an argument on causation based upon the structure of heavy machinery.

In 2013 Jane completed a nine-month secondment at the General Medical Council as an in-house Legal Advisor with a caseload of close to 30 active investigations. Having demonstrated her ability to handle complex cases and provide sound advice, she now receives regular instructions from the GMC to appear before the Medical Practitioners’ Tribunal Service (MPTS). She also acts for the Health and Care Professions Council.

Jane also defends in regulatory proceedings. In particular, she regularly represents registrant nurses before the Committee of the Nursing and Midwifery Council and has appeared to defend before the Health and Care Professions Council, the General Osteopathic Council and the Association of Optometrists.

Regulatory & Professional Disciplinary

As a List C Specialist Regulatory Advocate in Health & Safety and Environmental Law, Jane has considerable experience of criminal regulatory prosecution. Her skill-set is well-suited to the technical analysis required for this niche area of work.

Jane has often acted for local authorities in prosecutions under the Environmental Protection Act 1990 (e.g. disposal of waste and breach of enforcement notices) and the Food Safety Act 1990.

Jane has acted for Ipswich Borough Council in obtaining civil closure orders under the Anti-Social Behaviour Act 2003 at the Magistrates’ Court. Given the emergency nature of these applications, she was briefed not more than 48 hours before each hearing. Jane has also appeared in quasi-criminal applications in the magistrates’ and Crown Court, such as applications for Football Banning Orders and Anti-Social Behaviour Orders, which incorporate both civil and criminal rules of evidence.

Jane provides advice at every stage of proceedings and assists in directing the course of the investigation and prosecution within this specialist area of work.

Featured cases

  • R v A & A (2014) – Instructed to prosecute for a local authority for breach of a planning enforcement notice.

  • R v T (2012) – Instructed to represent South Cambridgeshire District Council in the prosecution of an individual for managing an unlicensed House in Multiple Occupancy contrary to the Housing Act. The property was badly maintained and judged by the Fire Department to be a fire hazard.

Featured cases

  • Germany v DJ (2015) – Instructed to appear in the magistrates’ court and in the Administrative Court to oppose the extradition on human rights grounds a British national accused of large-scale tax fraud.
  • France v BF (2009) – Instructed to represent a British national, whose extradition was sought by French authorities for murder (or equivalent). Unusual case because the authorities only knew of the client’s involvement in the death because he had disclosed it as part of the cleansing process before giving evidence for the prosecution as a convicted defendant. Opposed extradition on the grounds of delay, at first instance and in the Administrative Court.
