Article 2 of the European Convention on Human Rights (ECHR) protects the right to life. These Article 2: right to life A-Level Law revision notes explain the duties Article 2 places on the State, the tightly controlled circumstances in which potentially lethal force may be justified, and how these principles are applied to factual scenarios. Article 2 forms part of the Convention framework introduced through the Human Rights Act 1998 [Lesson 169. The Human Rights Act 1998] and is specifically required by AQA as Article 2.1 and Article 2.2.

Revision Notes 📚
What does Article 2 protect?
Article 2 of the European Convention on Human Rights protects the right to life.
AQA specifically requires knowledge of:
Article 2.1, the right to life
Article 2.2, justified exceptions to that right.
Article 2 gives particularly strong protection because loss of life cannot normally be reversed. However, it is important not to describe Article 2 as having no limitations. Article 2.2 expressly recognises limited circumstances in which a death resulting from State use of force will not violate the Convention.
The ECHR primarily places obligations on the State and its agents, such as the police. Under the Human Rights Act 1998 [Lesson 169. The Human Rights Act 1998], public authorities are required to act compatibly with Convention rights.
Article 2.1: the right to life
Article 2.1 requires the State to protect life. In examination answers, it is useful to separate this into two aspects:
Obligation | What it means |
Negative obligation | The State and its agents must not unlawfully or unjustifiably take life. |
Positive obligation | The State may sometimes be required to take reasonable steps to protect people whose lives are at serious risk. |
This distinction regularly appears in AQA assessment material. Article 2 has been interpreted as imposing both a duty on the State not to take life and a duty to protect and preserve life.
The negative obligation
The negative obligation means that State agents must not intentionally deprive a person of life unless the situation comes within the very limited provisions of Article 2.2.
The clearest examination example is the use of potentially lethal force by police.
If a police officer shoots and kills someone, the starting point should therefore be:
Article 2 is engaged.
The State has prima facie interfered with the person's right to life.
The issue becomes whether the use of force can be justified under Article 2.2.
Do not jump immediately to the conclusion that every death caused by police is automatically a breach. Article 2.2 must be considered.
The positive obligation
Article 2 is not limited to stopping the State from killing people. The State may also have a positive obligation to protect life.
A major authority used repeatedly in AQA materials is Osman v UK.
The principle is especially important where authorities such as the police know about a danger created by another person.
A useful examination test is:
Was there a real and immediate risk to life?
Did the authorities know, or ought they to have known, about that risk?
Were reasonable measures available within their powers which might have been expected to avoid the risk?
If these requirements are satisfied and the authorities fail to act appropriately, Article 2 may be breached.
Example
Police receive repeated reports that a violent former partner has threatened to kill an identified person. They then receive an emergency call stating that the former partner is outside the person's home carrying a weapon.
The facts strongly suggest:
an identified person is at risk
the danger is real and immediate
the police know about the danger
protective action may be available.
A failure to respond could therefore engage the State's positive obligation under Article 2.
AQA examiner material has specifically highlighted the importance of applying the Osman test, rather than merely stating that the police have a general duty to protect people.
You will develop this aspect further when studying protective policing [Lesson 184. Right to life: dangerous operations and protective policing].
Article 2 does not create a general right to die
Article 2 protects the right to life. It does not create a corresponding Convention right requiring the State to assist a person to die.
AQA tested this distinction directly in 2025. The false proposition was that Article 2 also gives everyone a right to die.
For Article 2: right to life A-Level Law revision, remember the direction of the protection:
Article 2 protects life. It should not be reversed into a general Convention right to have life deliberately ended.
Article 2.2: justified exceptions
Article 2.2 provides three tightly controlled circumstances involving the use of force.
A death will not necessarily violate Article 2 where it results from force which is no more than absolutely necessary for one of the following purposes.
Article 2.2 exception | Permitted purpose |
Article 2.2(a) | Defence of any person from unlawful violence |
Article 2.2(b) | Effecting a lawful arrest or preventing the escape of a person lawfully detained |
Article 2.2(c) | Action lawfully taken for the purpose of quelling a riot or insurrection |
These are specific exceptions. They are not a general licence for the police or other State agents to use lethal force whenever it appears convenient or merely reasonable.
Article 2.2(a): defence from unlawful violence
The most commonly examined exception is the use of force in defence of any person from unlawful violence.
This may include:
an officer defending themselves
an officer protecting another police officer
police protecting a member of the public
State agents responding to an apparently immediate threat of serious violence.
Example
An armed officer arrives at an incident and sees a person pointing what appears to be a loaded firearm at another person.
If the officer honestly believes that the victim is about to be shot, force may fall within Article 2.2(a).
That does not end the analysis. The force must still be no more than absolutely necessary.
Article 2.2(b): lawful arrest or preventing escape
Potentially lethal force may also fall within Article 2.2 where it is used:
to effect a lawful arrest, or
to prevent the escape of someone lawfully detained.
Again, the existence of a lawful arrest does not automatically justify killing the suspect.
The separate requirement of absolute necessity remains crucial.
Example
A suspect runs away from police after committing a minor offence. An officer has a lawful power to arrest the suspect.
That does not mean shooting the suspect is automatically lawful under Article 2.2(b). The court must still consider whether that degree of force was absolutely necessary and proportionate to the permitted purpose.
The domestic rules governing arrest connect this topic with later study of other Convention protections, including liberty and security [Lesson 173. Article 5: liberty and security].
Article 2.2(c): quelling a riot or insurrection
Article 2.2 also recognises force used in lawful action for the purpose of quelling a riot or insurrection.
As with the other exceptions, this does not remove the requirement of absolute necessity.
The correct examination approach is therefore not:
There was a riot, so lethal force was automatically lawful.
Instead ask:
Was the action genuinely directed towards the permitted Article 2.2 purpose?
Was the level of force no more than absolutely necessary?
Was the force strictly proportionate to the danger being addressed?
What does "no more than absolutely necessary" mean?
This is one of the most important phrases in Article 2.
AQA examiner material emphasises that the test is much stricter than simply asking whether force was sensible or reasonable.
In McCann v UK, the European Court of Human Rights explained that the force used must be strictly proportionate to one of the purposes allowed under Article 2.2.
This gives you a useful two-stage examination test:
Identify the Article 2.2 purpose.
Decide whether the degree of force was strictly proportionate to that purpose.
If less dangerous measures could realistically have dealt with the threat, that may support an argument that lethal force was not absolutely necessary.
McCann v UK and strict proportionality
McCann v UK is particularly important when applying Article 2 to police use of lethal force.
The case supports several principles used in AQA mark schemes and examiner reports:
lethal force must be no more than absolutely necessary
the force must be strictly proportionate
the circumstances as they appeared to the person using force are important
the planning and control of an operation may also matter.
The final point leads directly into dangerous operations and protective policing [Lesson 184. Right to life: dangerous operations and protective policing], where AQA requires more detailed consideration of operational planning.
What if the police make a mistake?
A factual mistake does not automatically mean there has been an Article 2 breach.
AQA materials use McCann v UK and Armani da Silva v UK to explain this principle.
A person using potentially lethal force may be able to rely on a mistaken belief where:
the belief was genuinely or honestly held, and
it was perceived for good reasons to be valid at the time.
The court considers the situation faced by the officer at the time, rather than judging the incident only with hindsight.
Example
An officer sees a person aiming what appears to be a real gun at members of the public. The officer shoots the person.
Afterwards, the weapon turns out to be a realistic replica.
The fact that the weapon was fake does not automatically establish a breach. The key questions include:
Did the officer honestly believe the weapon was real?
Were there good reasons for that belief?
Did the circumstances make lethal force appear absolutely necessary?
Was the force strictly proportionate to the perceived danger?
AQA's 2023 and 2025 examiner reports identify this type of reasoning as a feature of stronger responses.
Article 2 and the planning of operations
When potentially lethal State operations are involved, Article 2 is not concerned solely with the final split-second decision.
The way an operation was organised may also affect whether the State has complied with its obligations.
For example, Article 2 issues may arise where:
important intelligence was ignored
an operation involving firearms was badly planned
avoidable risks to life were created
officers were inadequately prepared for a foreseeable danger.
This is particularly relevant to dangerous operations and protective policing [Lesson 184. Right to life: dangerous operations and protective policing].
For this lesson, the key point is that the words absolutely necessary can require consideration of the wider circumstances, not merely the instant in which lethal force was used.
Applying Article 2 to an examination scenario
A strong answer should work systematically through the facts.
Step 1: identify why Article 2 is engaged
Ask whether the facts concern:
State agents taking life
a serious threat to someone's life which the State may have been required to address.
Step 2: identify the relevant obligation
Is the issue:
the negative obligation not to take life, or
the positive obligation to protect life?
Some scenarios may involve both.
Step 3: if the State used lethal force, identify Article 2.2
Ask whether the purpose was:
defence from unlawful violence
effecting a lawful arrest or preventing escape
quelling a riot or insurrection.
Do not simply say "Article 2.2 applies". Identify the correct paragraph.
Step 4: apply absolute necessity
Ask whether the force was:
no more than absolutely necessary
strictly proportionate to the permitted purpose.
Use every relevant fact.
Step 5: consider what the State knew
Where the issue concerns failure to protect life, consider:
whether there was a real and immediate risk
what the authorities knew or ought to have known
whether reasonable protective measures were available.
Step 6: deal with mistakes carefully
If an officer acted on mistaken information, consider:
whether the belief was honestly held
whether there were good reasons for regarding it as valid at the time.
Step 7: reach a reasoned conclusion
Avoid absolute assertions unless the facts clearly support them.
A better conclusion is:
The shooting is likely to fall within Article 2.2(a) because the officer honestly perceived an immediate threat to another person's life, and the force may be regarded as strictly proportionate to that danger.
This is stronger than simply writing:
The police were allowed to shoot because the suspect was dangerous.
Article 2 and later right-to-life topics
This lesson focuses on Article 2.1 and Article 2.2 themselves. AQA separately requires the relationship between the Convention right and English law. The specification includes homicide, self-defence, policing operations, civil negligence and investigation of deaths.
These are developed later through:
criminal law protection of life [Lesson 183. Right to life: criminal law]
dangerous operations and protective policing [Lesson 184. Right to life: dangerous operations and protective policing]
civil law and investigation [Lesson 185. Right to life: civil law and investigation].
The lesson sequence places Article 2 before those domestic-law applications so that you first understand the Convention test itself.
Key Words 🔑
Key word | Student-friendly definition | How it may be used in an exam |
Negative obligation | The State's duty not to take life in breach of Article 2. | Identify this where police or another State agent causes a person's death. |
Positive obligation | The State's duty in appropriate circumstances to take reasonable steps to protect life. | Apply it where authorities knew, or should have known, of a serious threat to an identified person. |
Real and immediate risk | A sufficiently serious and current threat to life capable of triggering the State's protective obligation. | Use this when applying the Osman principle to police failure to protect someone. |
Absolutely necessary | The demanding Article 2.2 standard governing the degree of force used by State agents. | Explain why identifying a permitted purpose alone is not enough to justify lethal force. |
Strictly proportionate | The requirement that the degree of force corresponds closely to the permitted Article 2.2 purpose and danger faced. | Use McCann v UK when analysing whether lethal force was justified. |
Hints from the Examiner Reports 💡
Examiner hint: Learn the actual Article 2 tests and then apply them closely to the facts. In 2023, stronger responses showed sound knowledge of Article 2, Osman, McCann and Armani da Silva and then used the scenario to decide whether lethal force was justified. Weaker responses confused the terms of Article 2 or failed to apply them precisely.
Examiner hint: For positive obligations, do not merely say that "the police have a duty to protect life". The 2025 report identified weaker responses that omitted the Osman test. Address the real and immediate risk, what the police knew or ought to have known, and whether reasonable protective measures were available.
Examiner hint: Use the exact Article 2.2 standard. Strong responses explained that lethal force must be no more than absolutely necessary and strictly proportionate, rather than treating ordinary reasonableness as sufficient.
Examiner hint: Mistakes must be analysed rather than simply dismissed. Stronger candidates recognised that an officer may rely on an honest mistake perceived for good reasons to be valid at the time.
Examiner hint: Stay focused on the facts you have been given. Examiner reports in both 2023 and 2025 noted that some students wasted time discussing matters such as when life begins or ends when those issues were irrelevant to the scenario.
Common Mistakes ⚠️
Mistake: Saying Article 2 has no exceptions
Why this is incorrect: Article 2.2 expressly recognises three limited situations involving the use of force.
How to improve: Memorise Article 2.2(a), (b) and (c), then identify which specific exception is relevant to the facts.
Mistake: Saying lethal force only needs to be "reasonable"
Why this is incorrect: Article 2 uses the much more demanding test that the force must be no more than absolutely necessary. McCann also requires strict proportionality.
How to improve: Use the phrases absolutely necessary and strictly proportionate explicitly in an application answer.
Mistake: Assuming a lawful arrest automatically justifies shooting
Why this is incorrect: Article 2.2(b) identifies a permitted purpose, but the degree of force must still satisfy the absolute-necessity test.
How to improve: Treat purpose and degree of force as two separate questions.
Mistake: Assuming every police mistake creates liability
Why this is incorrect: A mistaken belief may still be compatible with Article 2 where it was honestly held and perceived for good reasons to be valid at the time.
How to improve: Ask what the officer actually believed and what information available at the time supported that belief.
Mistake: Stating the positive obligation without applying the Osman test
Why this is incorrect: It is not enough to write that police generally protect the public.
How to improve: Apply the three key points: a real and immediate risk, knowledge or constructive knowledge of the danger, and reasonable protective measures that could have been taken.
Mistake: Discussing irrelevant Article 2 issues
Why this is incorrect: Lengthy discussion of unrelated questions, such as when life begins or ends, does not answer a scenario about police use of force or failure to protect someone.
How to improve: Underline the factual trigger in the question and select only the Article 2 rules that address it.

[5 marks]
Question 5
Police officers attend an armed incident at a petrol station. Nia sees a man, Omar, pointing what appears to be a handgun directly at a cashier. Omar ignores repeated instructions to lower the weapon and moves his finger towards the trigger. Nia shoots and kills him. The weapon is later discovered to have been a highly realistic replica which could not fire.
Having regard to Article 2, advise whether Nia's use of force is likely to be justified.
[10 marks]
Question 6
Pavel is suspected of stealing a bicycle. A police officer lawfully tells Pavel that he is under arrest. Pavel runs away across an empty playing field. The officer knows that Pavel is unarmed and has no history of violence. To prevent his escape, the officer shoots Pavel, killing him.
Advise whether Article 2.2(b) is likely to justify the officer's use of force.
[10 marks]
Question 7
During serious disorder, a group begins throwing petrol bombs towards police officers and nearby members of the public. Police initially retreat and issue repeated warnings. One person continues preparing another petrol bomb while standing close to a crowd. An armed officer shoots the person.
Explain how Article 2.2 may apply to the officer's actions.
[10 marks]
Question 8
A police operation is organised to arrest an armed suspect. Intelligence correctly indicates that the suspect is likely to carry a firearm, but this information is not passed to the officers sent to make the arrest. During the confused operation, an officer mistakenly believes the suspect is reaching for a gun and fatally shoots him.
Analyse the Article 2 issues raised by the shooting.

Answers and Indicative Mark Scheme
Question 1
Answer: C. [1 mark]
Article 2 has been interpreted as imposing a positive obligation on the State to protect life in appropriate circumstances.
Question 2
Award one mark for each:
Defence of any person from unlawful violence.
Effecting a lawful arrest or preventing the escape of a person lawfully detained.
Lawful action for the purpose of quelling a riot or insurrection.
Maximum: 3 marks.
Question 3
Indicative content:
Article 2 imposes a negative obligation requiring the State and its agents not to take life contrary to the Convention.
Article 2 also creates a positive obligation requiring the State in appropriate circumstances to take reasonable steps to protect life.
The positive obligation may arise where authorities know or ought to know of a real and immediate risk to an identified person.
Reasonable measures within the authorities' powers which could have been expected to avoid the danger should be considered.
Relevant reference to Osman v UK may strengthen the explanation.
For a high-level response, both obligations should be clearly distinguished rather than merely named.
Maximum: 5 marks.
Question 4
Indicative content:
AO1
Article 2 creates a positive obligation to protect life.
Under the Osman principle, consider a real and immediate risk, knowledge of the authorities and reasonable measures available.
AO2
Idris has previously attacked Joel.
Police have received repeated death threats.
Joel's emergency call identifies an immediate armed threat.
The police therefore knew, or clearly ought to have known, of a real and immediate danger.
Sending officers promptly appears to have been a measure within police powers which might reasonably have reduced the risk.
The unexplained forty-minute failure to respond therefore supports the argument that Article 2 was breached.
A reasoned alternative conclusion based on the facts should also receive credit.
Maximum: 5 marks.
Question 5
Indicative content:
AO1
Nia is a police officer and therefore a State agent.
Omar's death engages the negative obligation under Article 2.
Article 2.2(a) permits force no more than absolutely necessary in defence of any person from unlawful violence.
Under McCann v UK, lethal force must be strictly proportionate.
An honest belief perceived for good reasons to be valid at the time may still justify force even if later shown to be mistaken.
AO2
Omar appeared to be aiming a firearm directly at the cashier.
He ignored instructions to lower it.
His movement towards the apparent trigger increased the perceived immediacy of the danger.
Nia did not know that the firearm was a replica.
There were therefore strong reasons for an honest belief that the cashier faced an immediate threat to life.
AO3
Shooting was potentially strictly proportionate because the apparent threat was immediate and potentially fatal.
The later discovery that the firearm was incapable of firing does not automatically make the force unlawful.
On the facts, Article 2.2(a) is likely to justify the shooting.
Maximum: 10 marks.
Question 6
Indicative content:
AO1
Article 2.2(b) can apply where force is used to effect a lawful arrest or prevent escape.
The force must still be no more than absolutely necessary.
Strict proportionality must be considered.
AO2
Pavel's arrest is lawful, so the permitted purpose in Article 2.2(b) is potentially present.
However, Pavel is suspected only of bicycle theft.
He is known to be unarmed.
He poses no apparent threat of unlawful violence.
He is simply running away across an empty field.
AO3
Shooting him is highly unlikely to be strictly proportionate to the purpose of preventing escape.
The existence of a lawful arrest does not itself make lethal force lawful.
The officer is therefore likely to have violated Article 2.
Maximum: 10 marks.
Question 7
Indicative content:
AO1
Article 2.2(a) may apply because police and members of the public face unlawful violence.
Article 2.2(c) may also be relevant if the situation amounts to serious disorder falling within its terms.
Any force must be no more than absolutely necessary and strictly proportionate.
AO2
Petrol bombs present a potentially lethal danger.
The group has already attacked police and endangered members of the public.
Warnings were given and police initially retreated.
The person shot was apparently preparing another petrol bomb near a crowd.
AO3
These facts support an argument that there was an immediate threat of serious or fatal violence.
The officer may therefore argue that the shooting was absolutely necessary to protect life.
The precise availability of less dangerous alternatives would also be relevant.
A supported conclusion either way should receive credit.
Maximum: 10 marks.
Question 8
Indicative content:
AO1
Article 2's negative obligation is engaged because a State agent caused the death.
Article 2.2(a) may justify force used to protect against perceived unlawful violence.
McCann requires absolute necessity and strict proportionality.
An honestly held mistaken belief may be relied upon where perceived for good reasons to be valid at the time.
The broader planning and control of a potentially lethal operation may also be relevant.
AO2
The individual officer may genuinely have believed that the suspect was reaching for a firearm.
Whether there were good reasons for that belief depends on the circumstances at the scene.
However, police already possessed important intelligence that the suspect was likely to be armed.
The failure to communicate that information created avoidable confusion during a dangerous operation.
AO3
Even if the individual officer's immediate decision could be justified on the basis of an honest perceived threat, the State may still face Article 2 concerns arising from the planning and control of the operation.
A high-quality answer should therefore distinguish the officer's split-second decision from the wider conduct of the operation.
The final conclusion should weigh both aspects rather than treating the shooting in isolation.
Maximum: 10 marks.
