Constitutional Provisions

The United Kingdom does not have a single written constitution, "but an unwritten one formed of Acts of Parliament, court judgments and conventions."Robert Blackburn, "Britain's unwritten constitution", British Library, 13 March 2015. With regard to human rights, it is recalled that:

During the constitutional conflicts of the 17th century, the Petition of Right (1628) relied on [the 1215] Magna Carta for its legal basis, setting out rights and liberties of the subject including freedom from arbitrary arrest and punishment. The Bill of Rights (1689) then settled the primacy of Parliament over the monarch’s prerogatives, providing for the regular meeting of Parliament, free elections to the Commons, free speech in parliamentary debates, and some basic human rights, most famously freedom from "cruel or unusual punishment". 

The 1998 Human Rights Act gives domestic effect to the United Kingdom's obligations under the 1950 European Convention on Human Rights.

Police Use of Force

Rules on police use of force are spread across statutory instruments and the common law. Under the 1967 Criminal Law Act: 

A person may use such force as is reasonable in the circumstances in the prevention of crime, or in effecting or assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large.

This is also the position at common law with respect to self-defence or the defence of others, including by police officers and other law enforcement officials.College of Policing, "Armed Policing, Legal Framework", at: https://www.app.college.police.uk/app-content/armed-policing/legal-framework/#common-law.Within this general framework, the notion of what is to be determined as "reasonable" is clarified by the 2008 Criminal Justice and Immigration Act: 

The question whether the degree of force used by D [the person charged with the offence] was reasonable in the circumstances is to be decided by reference to the circumstances as D believed them to be...

if it is determined that D did genuinely hold it, D is entitled to rely on it ... whether or not—

(i) it was mistaken, or

(ii) (if it was mistaken) the mistake was a reasonable one to have made.S. 76(3) and (4), 2008 Criminal Justice and Immigration Act.

There is thus both a subjective and an objective element to this defence. The question of whether the degree of force used by a person was reasonable in the circumstances is to be decided by reference to those circumstances as that person genuinely and honestly believed them to be. This is so even if their belief is mistaken. Whether the degree of force used in the circumstances--as the person believed them to be--was actually reasonable will, however, be assessed objectively by the courts.

Particular rules on use of firearms exist in Scotland. Under the common law, three conditions must be met before the defence of self-defence or defence of another is available. These requirements, coming from the 1954 judgment in the case of HM Advocate v. Doherty,HM Advocate v. Doherty, 1954 JC 1 at 4-5.are:

i. There must be imminent danger to the life or limb of the accused,

ii. The force used in the face of this danger must be necessary for the safety of the accused – by this it is meant that the force must be both necessary in the circumstances and should be proportional to the threat which is being combated, and,

iii. If the person assaulted has means of escape or retreat, they are bound to use them.

In Scottish law the concept of ‘reasonable belief’ is outlined in the following guidance to officers

A police officer is not entitled to discharge a firearm against a person unless the officer has reasonable grounds for believing that the person is committing, or about to commit, an action likely to endanger the life or cause serious injury to the officer or any other person, and there is no other way to prevent the danger.

With respect to conducted electrical weapons (Taser©), the College of Policing sets policy guidelines, but these do not describe in which circumstances a Taser should and should not be used.

Use of Force in Custodial Settings

Under the Prison Service's use of force policy: 

2.1  The use of force by one person on another without consent is unlawful unless it is justified. 

2.2.  The use of force will be justified, and therefore lawful, only:
•    If it is reasonable in the circumstances
•    If it is necessary
•    If no more force than is necessary is used
•    If it is proportionate to the seriousness of the circumstances.HM Prison Service, "Use of Force", Prison Service Order No. 1600, 31 August 2005.

This complies with international legal standards. 

Police Oversight

The Independent Police Complaints Commission was mandated to conduct and oversee the investigation of complaints about police officers.S.10, 2002 Police Reform Act.Under the 2017 Policing and Crime Act, the Independent Police Complaints Commission (IPCC) was renamed the Independent Office for Police Conduct (IOPC). This change resulted, in part, from a widespread loss of confidence in the IPCC.

The IOPC declares that it

oversees the police complaints system in England and Wales. We investigate the most serious matters, including deaths following police contact, and set the standards by which the police should handle complaints. We use learning from our work to influence changes in policing.

We are independent, and make our decisions entirely independently of the police and government.

The Police Ombudsman for Northern Ireland is an independent system for the handling of complaints about the conduct of police officers in Northern Ireland.

There is also the possibility to hold police services accountable under criminal law for manslaughter by virtue of the 2007 Corporate Manslaughter and Corporate Homicide Act.In England, Wales and Northern Ireland, the offence is called corporate manslaughter, and in Scotland it is called corporate homicide.Under Section 1(1) of the 2007 Act, an organisation is guilty of an offence if the way in which its activities are managed or organised:

a. Causes a person’s death; and

b. Amounts to a gross breach of a relevant duty of care owed by the organisation to the deceased.

An organisation is guilty of an offence only if the way in which its activities are managed or organised by its senior management is a substantial element in the breach. Section 5 of the 2007 Act makes it clear that it applies to policing and law enforcement operations.

Views and Concluding Observations of United Nations Treaty Bodies

In its 2015 Concluding Observations on the United Kingdom's seventh periodic report on its implementation of the ICCPR, the Human Rights Committee noted with concern with respect to Northern Ireland 

the multiple independence and effectiveness shortcomings alleged in relation to the Police Ombudsman’s ability to investigate historical cases of police misconduct.Human Rights Committee, Concluding observations on the seventh periodic report of the United Kingdom of Great Britain and Northern Ireland, UN doc. CCPR/C/GBR/CO/7, 17 August 2015, §8. 

With respect to the use of conducted electrical weapons (e.g. Taser©), in its 2013 Concluding Observations on the United Kingdom's fifth periodic report on its implementation of CAT, the Committee against Torture expressed deep concern

at instances where electrical discharge weapons have been used on children, persons with disabilities and in recent policing operations where the serious threat of violence was questioned....Committee against Torture, Concluding Observations on the United Kingdom's fifth periodic report, UN doc. CAT/C/GBR/CO/5, 24 June 2013, §26.

It called on the United Kingdom to ensure

that electrical discharge weapons are used exclusively in extreme and limited situations – where there is a real and immediate threat to life or risk of serious injury – as a substitute for lethal weapons and by trained law enforcement personnel only. The State party should revise the regulations governing the use of such weapons with a view to establishing a high threshold for their use and expressly prohibiting their use on children and pregnant women.Committee against Torture, Concluding Observations on the United Kingdom's fifth periodic report, UN doc. CAT/C/GBR/CO/5, 24 June 2013, §26.

The Committee was of the view

that the use of electrical discharge weapons should be subject to the principles of necessity and proportionality and should be inadmissible in the equipment of custodial staff in prisons or any other place of deprivation of liberty.Committee against Torture, Concluding Observations on the United Kingdom's fifth periodic report, UN doc. CAT/C/GBR/CO/5, 24 June 2013, §26.

It urged the United Kingdom "to provide detailed instructions and adequate training to law enforcement personnel entitled to use electric discharge weapons, and to strictly monitor and supervise their use".Committee against Torture, Concluding Observations on the United Kingdom's fifth periodic report, UN doc. CAT/C/GBR/CO/5, 24 June 2013, §26.

Regional

A number of cases concerning alleged unlawful use of force in law enforcement by the UK police and security forces have come before the European Court of Human Rights. The most important are the McCann and da Silva cases.

McCann and others v. United Kingdom

In its 1995 judgment, the European Court found a violation of the right to life by the United Kingdom, not for the decision by British soldiers to shoot and kill three members of the Irish Republican Army (IRA) who were on a bombing mission in Gibraltar, but for the failure to arrest them beforehand. This judgment is one of the most important the European Court has ever made, recognising a "duty of precaution" under Article 2 (the right to life) of the 1950 European Convention on Human Rights.

da Silva v. United Kingdom

In the da Silva case, which concerned the police shooting to death of a Brazilian electrician, Jean-Charles de Menezes, in the London Underground in 2005. Mr de Menezes was mistaken for a wanted terrorist. The European Court reaffirmed that an honest but mistaken belief on the part of the police did not amount to a violation of the right to life. 

National

Many cases, investigations, and reports have sought to address unlawful police use of force in the United Kingdom. The following are a number of key examples.

In 1999, a judge-led inquiry into the Metropolitan Police Force's investigation of the death of a Black youth, Stephen Lawrence, concluded that the Met was guilty of "institutional racism". Fifteen years later, in 2014, Janet Hills, the chair of the Met's association for black police officers, called on the Metropolitan Police Commissioner, Sir Bernard Hogan-Howe, to admit that the force was still institutionally racist.

In 2011, the Independent Police Complaints Commission concluded that a police officer had used "excessive force" in dragging a protester in a wheelchair across a road and that the Metropolitan Police Service was wrong not to recommend criminal charges against him. The IPCC criticised the internal inquiry into the incident and called on the Met to apologise to the disabled student, Mr Jody McIntyre. Criminal charges could not be brought against the officer as a six-month legal deadline had already expired. The IPCC recommended that the officer become subject to "management action".

In 2012, the IPCC urged the Metropolitan Police to reduce the use of excessive force following complaints against specialist riot officers.

In 2015, it was reported that 3,000 police officers were under investigation for alleged assault in England and Wales.

In 2016, a police officer and a police community support officer were convicted of misconduct in a public office and sent to prison for their failure to protect a disabled Iranian refugee, Bijan Ebrahimi. The 44-year-old was punched and kicked to death outside his Bristol home and his body set on fire by neighbour Lee James, who wrongly suspected he was a paedophile. In 2017, the IPCC suggested that Avon and Somerset police officers may have been biased against Bijan Ebrahimi because of his race.
