Jane is currently ranked in the Legal 500 as a leading junior at the London Bar in both Crime and Professional Discipline and Regulatory, and on the South-Eastern Circuit in Crime. She is described as “an outstanding advocate… She strikes a perfect balance between approachability and delivering balanced, legally sound and understandable advice.” and “an excellent lawyer who has extensive experience in her field, excellent legal knowledge and a strong character that allows her to deal with complex cases and issues”.

She is a persuasive advocate and an adept technical lawyer with the organisational and communication skills necessary for varied and complicated cases.  Her commitment to detailed case analysis, combined with her intellect and friendly manner, have enabled her to build a successful and diverse practice as a criminal and regulatory barrister.  She is expert at witness handling, both in examination-in-chief and cross-examination, and has a style which adapts easily to the various different forums in which she appears.



Jane Oldfield has built a strong all-round criminal practice. As well as accepting instructions from a number of highly respected defence firms, Jane is a Grade 4 CPS prosecutor and has also prosecuted on behalf of various public and private bodies, including the Health & Safety Executive, RSPCA, the Department for Business, Innovation and Skills, and local authorities. Her practice embraces the entire range of criminal conduct. She is an extremely experienced jury advocate, and has appeared before the appellate courts on numerous occasions.

As a prosecutor, Jane is fair but robust, and works well as part of a team. As a defender she is tenacious and committed, and takes very seriously the trust reposed in her by her clients.

Sexual OffencesViolent CrimeOrganised CrimeFraudProceeds of CrimeRoad Traffic

Jane is regularly instructed for both the prosecution and the defence in cases of serious sexual offences, involving both adults and children. She is on the CPS Rape Panel, and her wide experience encompasses offences of rape, sexual assaults, inciting a child to engage in sexual activity, brothel-keeping, grooming and indecent images, amongst others.

Jane has regularly mounted and defended arguments relating to s.41 cross-examination about a complainant’s sexual history, abuse of process based on delay, hearsay and bad character.

She is an approachable advocate who possesses excellent judgment. She is committed to providing first class client care and is particularly strong in working with vulnerable witnesses.

From privately-instructed magistrates’ court trials for battery to the most serious offences of s.18 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 has built up considerable experience in complicated confiscation proceedings and is well-versed in the Proceeds of Crime Act (POCA), the Drug Trafficking Act (DTA) and Criminal Justice Act (CJA) confiscation regimes as well as the restraint legislative framework. 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 s.17 POCA defendant’s responses and has also represented clients in contested cash forfeiture proceedings.

Jane has a strong practice defending in private road traffic cases of all kinds. She gives fair, realistic advice on the law and prospects of success. She has a wide knowledge of road traffic case law and the myriad of defences available.

Jane understands the paramount importance of road traffic cases for those whose livelihood depends on their own and their employees’ driving records, as well as the implications that a conviction can have on licensing and standing with the Traffic Commissioners.

  • R v G (2018) Represented a high-profile professional on charges of drink driving arising from a road accident in which a cyclist was injured. Secured a favourable sentence and avoided adverse publicity.
  • R v DD (2015) A favourable sentence for an individual who worked in the transport industry and was charged with driving with excess alcohol.

  • R v JR (2017) Causing death by careless driving whilst unfit through drink.

Regulatory & Professional Discipline

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.

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.

HealthcareHealth & Safety and Environment

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 Committees (now one Committee) of the Nursing and Midwifery Council and has appeared to defend before the Health and Care Professions Council and the General Osteopathic Council.

  • NMC v AT (2018) Represented a nurse who admitted dishonesty by writing a false reference for another healthcare professional. Managed to secure a short suspension despite the seriousness of the charges.
  • GMC v Dr G (2018) For the GMC: a doctor convicted abroad of indecent acts with significant health problems. Several experts were called as to the link between the offending and the doctor’s health.
  • GOsC v TV (2017) Defence of an osteopath accused of clinical misconduct, data protection breaches and failing to properly obtain consent. Expert evidence called by both sides. The vast majority of the charges were not found proved and the least sanction available was imposed.
  • HCPC v RC (2017) For the HCPC: allegations against a paramedic for driving a marked ambulance car at excessive speeds.
  • HCPC v CB (2017) Represented a physiotherapist regarding allegations of dishonesty and poor record-keeping. Despite factual admissions made, no misconduct found proved.
  • GMC v Dr J (2016) For the GMC: allegations of sexual misconduct against two patients.
  • NMC v DC (2016) Defence of an NHS Direct nurse accused of multiple allegations of clinical misconduct, including an allegation of contributing to the death of a child.
  • GMC v Dr A (2016) For the GMC: multiple allegations of clinical misconduct, dishonesty, breach of interim conditions and serious attitudinal and communication failings.

As a List C Specialist Regulatory Advocate in Health and 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 provides advice at every stage of proceedings and assists in directing the course of the investigation and prosecution within this specialist area of work.

  • R v JM (2017) Advised a client regarding allegations brought by the Environment Agency of operating a waste facility without a permit.
  • • HSE v F Ltd (2015) Led junior successfully prosecuting a multi-national corporation charged with breaching its duty to non-employees. Part of the transport system for a wind turbine blade fell, killing one and seriously injuring another construction worker. Succeeded in marshalling witnesses from all over the world to give evidence via Skype. [Press Report ]
  • R v A & A (2014) Prosecuted for a local authority for breach of a planning enforcement notice. Successfully opposed an abuse of process argument and application to dismiss, on complicated and novel legal points about interpretation of planning permissions, ‘change of use’ and validity of the enforcement notice. The rulings were later upheld on appeal.
  • R v T (2012) Represented 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.

International Representation


Jane has appeared in extradition cases both at first instance and before the High Court on appeal, and has experience of the complex legal arguments and thorny factual issues which can arise.

  • Germany v DJ (2015) Appeared 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) Represented 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.


Jane has been described in previous editions of Legal 500 as:

  • showing “initiative, firmness of purpose and ability beyond her call.”
  • “she can be relied upon to crystallise complex arguments clearly and concisely.”
  • “hardworking, committed and determined.”
  • “Bright and hardworking, with exceptional judgement.”
  • “Client-friendly, and noted for her meticulous preparation.”
