Police  Law & Public law

Dijen is consistently ranked by Chambers & Partners as a leading silk for Police Law and Inquests & Inquiries.

He advises and represents police forces and other police organisations in relation to matters of civil and public law unique to policing such as:

• Use of force by police
• Entry, search and seizure by police officers, under search warrants and/or under PACE powers;
• Police powers, including defending judicial review claims brought against police forces challenging their exercise of powers;
• Police involved shootings
• Counter terrorism;
• Defending claims brought against police alleging assault (including use of firearms), false imprisonment, malicious prosecution, misfeasance in a public office and discrimination;
• Defending human rights claims;
• Policing protests;
• Charging organisers for the cost of providing Special Police Services at events such as football matches and large concerts; and
• Information Law: data protection and freedom of information.

Notable cases include:

R (Commissioner of the Police of the Metropolis) v PAT [2024] EWHC 2348 (Admin), and (for remedy) [2024] EWHC 3263 (Admin) (Lieven J): Dijen represented the Commissioner of Police in his successful judicial review challenge to the PAT’s decision to set aside an officer’s dismissal for gross misconduct and to remit the matter to a fresh Panel with back pay. The High Court quashed the PAT’s decision on the ground that the misconduct panel’s findings were open to them and that their finding that the officer had deliberately misled them on important issues was a matter which could reasonably lead to a finding of gross misconduct. The officer’s dismissal therefore stood. In the subsequent remedy judgment, the Court acceded to the Commissioner’s application that the officer (the Interested Party in the claim) repay to him the back pay sums she had received for the period prior to her return to service under the PAT’s decision, a period during which she was not rendering service as a constable.

R (Dunne) v Independent Office for Police Conduct [2023] EWHC 3300 (Admin) (Ritchie J): a case in which the Claimant was deliberately struck on the head with the muzzle of a firearm by a police officer, causing him a catastrophic brain injury. His mother (as litigation friend) alleged that the Defendant’s investigation into the matter breached his rights under Article 2 ECHR. The Court held that Article 2 ECHR required the IOPC to provide to the Claimant sufficient disclosure during its investigation and a draft report to enable effective participation by her and ought to have conducted face to face interviews with the involved officers. He held that it was obliged to published its investigation report. The decision is most relevant to official investigations where grave injury, just short of death, is intentionally inflicted by agents of the state, given that there will be no inquest to discharge the state’s Article 2 investigative obligation.

ABC & others v Derbyshire County Council and Chief Constable of Derbyshire Constabulary [2023] EWHC 986 (KB) (Hill J): highly unusual case involving multi-agency working where Fabricated or Induced Illness, a form of child abuse, was suspected. The Claimants were parents (who had been arrested) and their children (who had been removed from their parents’ case by police pursuant to s.46 of the Children Act 1989). They claimed over £2.5m in damages and costs for false imprisonment, human rights violations and negligence. Dijen (leading Matthew Holdcroft) represented the Chief Constable before Mrs. Justice Hill, who dismissed all of the claims with costs.

R (Chief Constable of South Yorkshire) v Crown Court at Sheffield and Kelly [2021] EWCA Civ 1699, Court of Appeal (Moylan, Males & Phillips LJJ): appeal concerning a police injury pension sought 11 years after the officer’s retirement, his entitlement to a back-dated award, the jurisdiction of the Crown Court to hear and determine the claim and its power to award interest in pension appeals.

Eckland v Chief Constable of Avon and Somerset Constabulary [2021] EWCA Civ 1961, Court of Appeal (Underhill LJ (Vice-President of the Court of Appeal, Coulson & Carr LJJ): Dijen represented the police in an appeal concerning the liability of a chief constable for a discriminatory dismissal carried out by an independent police misconduct hearing panel over which she had no control and whose discrimination she could not have prevented. The force argued that the officer has a claim against the members of the panel for compensation for discrimination against him in the carrying out of a public function. The appeal was dismissed and the Supreme Court (Lord Reed PSC, Lord Sales and Lord Hamblen JJSC) refused permission to appeal.

Williams v Information Commissioner [2021] UKUT 149 (AAC), [2022] 1 WLR 259, Upper Tribunal (Judge Jones): this Upper Tribunal appeal concerned a Freedom of Information Act 2000 request seeking information concerning a port stop performed by police pursuant to Sch 7 of the Terrorism Act 2000. Dijen acted for the Chief Constable of Kent Police. The case was remitted to the first tier tribunal for a further hearing in which the Chief Constable succeeded.

R (AB) v Chief Constable of Hampshire Constabulary [2019] EWHC 3461 (Admin), Divisional Court (Dame Victoria Sharp PQBD & Lewis J): Dijen successfully defended the Chief Constable in a judicial review claim alleging a failure to discharge her duty to investigate credible allegations of Article 3 harm made by a 15-year old boy with severe learning and communication difficulties where it had not been possible to find a registered intermediary to assist in his police interview. The Court also gave important guidance concerning the admissibility of, and prerequisites for the admission of, expert evidence which has been followed a number of times since.

Re M (Children) (Disclosure to the Police) [2019] EWCA Civ 1364, [2019] 4 WLR 115, Court of Appeal (Sir Andrew McFarlane (President of the Family Division), Simon and Nicola Davies LJJ): Acting for the Chief Constable of Leicestershire Police, Dijen successfully resisted an appeal, brought by parents in care proceedings, against an order for disclosure to police of their witness statements given under compulsion in those proceedings. The parents are among the many people returning to the UK from Syria with their children.

Capita Customer Management Ltd v Ali & Chief Constable of Leicestershire v Hextall [2019] EWCA Civ 900, [2020] ICR 87, Court of Appeal (Sir Terence Etherton MR, Bean and Rose LJJ): represented the Chief Constable in his successful appeal against the decision of the EAT (Slade J) that paying men statutory shared parental leave pay potentially constitutes indirect sex discrimination. The EAT decision had been the cause of widespread concern among employers. An appeal to the Supreme Court by the officer in the Hextall case was refused permission.

MLIA & CLEL v Chief Constable of Hampshire Constabulary [2017] EWHC 292 (QB) (Lavender J): Dijen successfully defended the police (leading Mark Thomas) in a claim brought by a mother and daughter who reported serious allegations of domestic violence against the daughter’s ex-partner to police in 2005.

R (A & others) v The Central Criminal Court & Anor [2017] EWHC 70 (Admin), [2017] 1 WLR 3567 (Gross LJ & Ouseley J): Dijen appeared at the Old Bailey in order to apply for search warrants in a highly sensitive investigation and successfully defended claims for their quashing. The police were permitted to retain the mobile phones seized.

Ipswich Town Football Club Co Ltd v Chief Constable of Suffolk Constabulary [2017] EWCA Civ 1484, [2017] 4 WLR 195, Court of Appeal (Lord Briggs, Gloster & Gross LJJ): Dijen represented the police (leading Catriona Hodge) in a claim concerning the right of police to charge for the policing of events. The force were successful at first instance but the Court of Appeal overturned the judgment.

Koraou v Chief Constable of Greater Manchester Police [2015] EWCA Civ 646, [2016] QB 161, Court of Appeal (Lord Dyson MR, Laws & Kitchin LJJ): Dijen acted for the Chief Constable, defending the claimant’s appeal in one of the first two cases (the other being DSD v Commissioner of Police, with which it was heard) to reach the Court of Appeal, concerning whether Article 3 imposes an investigatory duty, the breach of which sounds in damages. The Chief Constable was successful.

Chief Constable of Devon and Cornwall Constabulary v Allard [2015] EWCA Civ 42, [2015] ICR 875, Court of Appeal (Longmore, Patten & Gloster LJJ): with Jeremy Johnson KC, Dijen represented the Chief Constable (as he had below) in this appeal concerning overtime entitlements of police informant (source) handlers.

R (M) v Chief Constable of Hampshire Constabulary & Secretary of State for the Home Department [2014] EWCA Civ 1651, [2015] 1 WLR 1176, Court of Appeal (Moore-Bick, Tomlinson & King LJJ): Dijen represented the Chief Constable before the Court of Appeal who held that the force did not breach a sex offender’s Article 8 rights by conducting unannounced visits to assess his risk of reoffending.

R (Mackaill & ors) v Independent Police Complaints Commission & ors [2014] EWHC 3170 (Admin), [2015] ACD 19, Divisional Court (Davis LJ & Wilkie J): This case arose out of a meeting between Police Federation officers and the Rt Hon Andrew Mitchell MP shortly after the notorious ‘Plebgate’ incident at the gates of Downing Street which ended Mitchell’s career.

Greatrex v Chief Constable of Gwent Constabulary: Dijen acted for the Chief Constable whose officers had arrested a 67-year old man, who had never before been in trouble with the police and who was released without charge. Every aspect of the arrest was challenged but the focus was on necessity. After a 5-day trial before HHJ Seys-Llewellyn KC and a jury, the jury returned verdicts in the chief constable’s favour.

R (A) v Chief Constable of Kent Constabulary [2013] EWCA Civ 1706, Court of Appeal (Pitchford, Beatson & Gloster LJJ): Enhanced Criminal Records Certificate case concerning a nurse.

R (Minter) v Chief Constable of Hampshire Constabulary & Secretary of State for the Home Department [2013] EWCA Civ 697, [2014] 1 WLR 179, Court of Appeal (Laws, Moore-Bick & Beatson LJJ): claimant held to be subject to the sex offenders’ notification regime for life. Dijen represented the successful chief constable.

Inquests & Inquiries

Dijen has decades of experience in the field of inquests and inquiries. His experience as a doctor often gives him the edge in inquests, especially where there are complex scientific and medical questions to be answered. His work includes deaths in custody and following contact with the police, and unexpected deaths in hospital, both in the National Health Service and in the private sector. Chambers & Partners has previously noted that he’s “a creative thinker and an absolutely outstanding cross-examiner” and “an enormously impressive and engaging advocate, he is very precise both orally and in writing, and he takes no prisoners.”

He represented (with Alex dos Santos) the Building Control Surveyor responsible for the Grenfell Tower refurbishment who was a core participant in the Grenfell Tower Inquiry.

Notable Cases Include:

Personal Injury & Clinical Negligence

As a former practising doctor, Dijen is regularly instructed in cases involving personal injury and clinical malpractice, including professional misconduct and clinical negligence claims. His medical background makes him a particularly effective cross-examiner of medical experts and gives him a natural facility with medical and scientific material (including reading indecipherable doctors’ notes!).

Between 1986 and 1991, Dijen read medicine at the United Medical and Dental Schools of Guy’s and St Thomas’. In 1988, he won the Sir Frederick Gowland Hopkins’ Prize for Biochemistry, awarded for the best examination and viva performance in that subject, and in 1991, Dijen was awarded a M.B., B.S. degree with Distinction in Surgery. Less than 10% of all London University medical graduates gained a Distinction in any of the Finals subjects in 1991.

He then practised medicine full time for a year, gaining Full Registration with the General Medical Council (which he continues to hold today), and continued to practise on a locum basis thereafter to fund his legal training.

Notable cases include:

•  Representing a primary care trust in a case involving a doctor accused of indecently assaulting a patient in which the doctor mounted an unsuccessful appeal to the Administrative Court on a point concerning legal professional privilege;
• Acting for a young man who sustained a very serious brain injury in a car accident and negotiating a settlement of just over £1.2 million plus costs.
• Acting for a husband and wife who sustained psychiatric injury when they witnessed their daughter being struck by a car driven by a drunk driver on Christmas morning. She succumbed to her injuries a month later and the couple recovered (in settlement) over £1 million in damages.
• Appearing on behalf of a man gravely injured when knocked off his motorcycle by a Range Rover being driven by a well-known footballer. He secured settlement just short of £1 million.
• Representing a former SAS soldier who was crushed by a 2-tonne machine being moved negligently by his business partner. The defendant disputed liability, alleging that the claimant had devised the negligent system of moving the machine. The liability trial in the High Court ended with the claimant succeeding on liability and recovering his costs on the indemnity basis. He settled his claim for £750,000.

Employment

Dijen has extensive experience in employment law, both generally and specifically in the police and medical sectors. Many of his cases are at Court of Appeal level. Illustrative examples of his work include:

Kalam v Chief Constable of West Midlands Police (2023) 1301519/2021, Employment Tribunal (Employment Judge Camp): leading Aaron Rathmell, represented the Chief Constable of West Midlands Police in one of the largest sex discrimination claims brought by a police officer against the police force.

R (Chief Constable of South Yorkshire) v Crown Court at Sheffield and Kelly [2021] EWCA Civ 1699, Court of Appeal (Moylan, Males & Phillips LJJ): appeal concerning a police injury pension sought 11 years after the officer’s retirement, his entitlement to a back-dated award, the jurisdiction of the Crown Court to hear and determine the claim and its power to award interest in pension appeals.

Scope v Thornett [2006] EWCA Civ 1600, [2007] ICR 236, Court of Appeal: Dijen successfully represented the charity in its appeal against a ruling of the EAT against it on the assessment of compensation. The Court of Appeal agreed that, even if there was a degree of speculation involved in the question whether the employee would have lost her job in any event, it was the duty of the tribunal to assess the probability that that would happen in determining compensation.

National Power v Young [2001] ICR 328: Court of Appeal: Time Limits in Equal Pay claims brought in an employment tribunal.
