2.4 Criminal Liability, Civil Liability and Human Rights

Key Takeaways

  • Unlawful or excessive force can be prosecuted as assault or battery; deaths linked to unlawful restraint may lead to very serious criminal charges including manslaughter investigations
  • Civil claims (for example negligence or personal injury) can be brought by the subject or third parties even when criminal charges are not pursued
  • Human Rights Act considerations include Article 2 (right to life), Article 3 (prohibition of torture and inhuman or degrading treatment), and Article 5 (right to liberty and security)
  • SIA licence suspension or revocation, employer discipline, and long-term career damage are realistic professional consequences of unlawful force
  • Accurate, timely reporting and cooperation with investigations are professional obligations after any use of force

2.4 Criminal Liability, Civil Liability and Human Rights

Quick Answer: If force is unlawful or excessive you can face criminal charges (assault/battery; far more serious offences if someone dies), civil claims for injury, human rights arguments under Articles 2, 3 and 5, plus SIA licence and employer sanctions. Report honestly; never rely on silence or a cover story.

Sections 2.1–2.3 explained authority, reasonable force, and duty of care. This section covers what happens when things go wrong — or when investigators must check whether they did. Understanding liability is not about scaring you out of protecting people; it is about showing why last resort, minimum force, monitoring, and reporting are non-negotiable.

Criminal liability

Assault and battery (everyday language for the exam)

In everyday and training language, unlawful physical contact or the infliction of unlawful force can amount to assault / battery type offences under the criminal law of the relevant UK jurisdiction. Exact offence labels and charging options vary, but the operational message is stable:

  • Force without legal justification is criminal
  • Force that starts justified becomes criminal if it becomes excessive or continues as punishment
  • “They deserved it” is not a legal defence

Examples that commonly create criminal risk:

  • Punching a person who is already restrained and compliant
  • Using a technique that foreseeably causes injury when a safer taught option was available and sufficient
  • Continuing a dangerous ground restraint after resistance has stopped
  • Striking someone solely for verbal abuse

More serious harm and manslaughter risk

If unlawful force causes grievous injury or death, investigators will consider much more serious offences. Where death follows restraint, police and prosecutors may examine whether the force was unlawful and whether the manner of restraint contributed to death (for example through positional asphyxia, neck compression, or failure to get medical help).

You do not need courtroom detail for Level 2. You do need this professional truth:

People can die under restraint. If the restraint was unlawful or grossly careless, criminal liability can include investigation for manslaughter or other serious homicide-related offences depending on the facts and jurisdiction.

Even when death is not intended, the criminal law can still treat fatal unlawful violence as extremely serious. Medical monitoring and early emergency calls are part of staying on the right side of both duty of care and criminal risk.

Self-defence and s.3 as defences, not slogans

If charged, an operative may rely on lawful authority — for example reasonable force under CLA 1967 s.3 or common-law defence principles in England and Wales. Those defences fail if the force was not necessary/reasonable or if the story is dishonest. CCTV, body-worn video, colleague evidence, and medical findings often decide credibility.

Civil liability

Criminal law is about public prosecution and punishment. Civil law is about claims between people (and companies), usually for compensation.

Typical civil routes after a security incident

Claim themeWho might claimTypical allegations
Personal injury / trespass to the personSubject of forceUnlawful contact, excessive force, injury
NegligenceSubject, sometimes third partiesBreach of duty of care causing loss
Employer vicarious liabilityClaim against company for staff actsStaff torts committed in the course of employment
Secondary victims / other injured personsColleagues or bystanders in some casesInjury from chaotic or negligent intervention

Important practical points:

  • A person can bring a civil claim even if the police take no criminal action
  • The standard of proof in civil cases is lower than in criminal cases (balance of probabilities)
  • Employers may be sued as well as or instead of the individual, but individuals can still be named and can still lose their job and licence
  • Settlements and judgments can be financially and reputationally severe for venues and officers

Civil risk is reduced by the same habits that reduce criminal risk: lawful necessity, proportionate techniques, welfare monitoring, first aid, and accurate records.

Human Rights Act considerations

The Human Rights Act 1998 gives effect in UK law to rights from the European Convention on Human Rights. Not every nightclub ejection is a full human-rights court case, but the Convention articles shape public expectations, training standards, and how serious incidents (especially involving public authorities or deaths) are investigated. Security staff should know the articles most relevant to restraint.

Article 2 — Right to life

Article 2 protects the right to life. For restraint practice it implies:

  • State and public systems must take restraint deaths seriously
  • Methods that create foreseeable lethal risk must be tightly controlled and avoided unless truly justified
  • After a death or near-death, thorough investigation and learning are expected
  • Operatives must get medical help promptly and not use force that foreseeably endangers life without justification

Even in private security settings, a restraint death will attract intense scrutiny from police, coroners (or equivalent), regulators, media, and civil lawyers. Article 2 language appears in official reviews of restraint-related deaths and informs why positional asphyxia and neck holds are treated as high risk in training.

Article 3 — Prohibition of torture and inhuman or degrading treatment

Article 3 is absolute in the sense that torture and inhuman or degrading treatment are forbidden — there is no “reasonable torture”. For security work, the relevant risk is inhuman or degrading treatment, for example:

  • Deliberate humiliation as part of ejection
  • Pain or injury inflicted as punishment rather than control
  • Holding someone in a degrading way when unnecessary
  • Ignoring severe suffering during restraint

Not every rough incident meets the Article 3 threshold, but training that forbids pain compliance as a goal and demands dignity aligns with Article 3 values. Conduct that looks like a beating in uniform is exactly what Article 3 is designed to prevent.

Article 5 — Right to liberty and security

Article 5 protects people from arbitrary deprivation of liberty. Restraint, locked rooms, prolonged detention by security pending police, or blocking someone from leaving can raise liberty issues.

Key operational ideas:

  • Any deprivation of liberty must be lawful and for a legitimate purpose recognised by law
  • Holding someone “because we are annoyed” is not enough
  • Detention should last only as long as necessary (for example until police arrive after a lawful citizen’s arrest situation, or while imminent violence is prevented)
  • People should be told, where practicable, what is happening and why
  • Hand over to the police promptly; private security is not a private prison service

False imprisonment style civil claims can overlap with Article 5 themes when someone is unlawfully detained.

How the three articles work together in PI

ArticleRestraint angle
2 LifeDo not use foreseeably life-threatening force/positions without true justification; get help fast
3 Inhuman/degradingNo punishment beatings; no gratuitous humiliation or cruelty
5 LibertyOnly lawful, necessary, time-limited restriction of freedom

Professional and licence consequences

Separate from courts, your career can end after a bad use-of-force incident.

SIA licence

The Security Industry Authority can refuse, suspend, or revoke licences where an individual is not considered fit and proper. Criminal convictions, serious complaints, and evidence of violent misconduct are classic risk factors. Losing a licence can mean losing the legal ability to work in licensable roles.

Employer discipline

Venues and security companies may:

  • Suspend pending investigation
  • Dismiss for gross misconduct
  • Refuse future shifts or references
  • Cooperate with police and SIA by providing CCTV and reports

Insurance and deployability

Companies may find insurance harder or refuse to deploy staff with violent incident histories. “Nobody pressed charges” does not mean “you are fine to work tomorrow”.

Reporting obligations and good practice

After any use of force, professional practice includes:

  1. Immediate welfare — subject, colleagues, public
  2. Inform supervisors and follow site protocols
  3. Call police/medical services when required (often already done mid-incident)
  4. Write an incident report while facts are fresh — what you saw, believed, said, which techniques, duration, injuries, witnesses, CCTV availability
  5. Be honest — do not invent threats or omit the “extra shove”
  6. Do not collude on false accounts; that can add separate criminal offences (for example perverting the course of justice type risks) on top of the original force issue
  7. Support investigations — provide statements as required
  8. Reflect and learn — debrief, CPD, and technique correction

Reporting is not bureaucracy for its own sake. It is how employers spot dangerous patterns, how innocent staff defend lawful actions, and how injured people get a fair account.

Putting the chapter together

ThemeSection
When force may be authorised (statute/common law; no special SIA powers)2.1
How much force (necessary, proportionate, reasonable belief)2.2
Welfare during and after; challenge excess; employer duties2.3
Criminal, civil, human rights, licence, reporting2.4

If you remember only one sentence from Chapter 2, make it this:

Use physical intervention only when the law allows it, only as much as necessary and proportionate, care for everyone involved until they are safe, and account for what you did.

That sentence keeps people alive, keeps you employable, and matches what the SIA Level 2 Physical Intervention theory paper is designed to test.
