Q

Is it enough for the act to cause fear or apprehension?

A

No, fear alone is not sufficient; there must be a risk of physical harm.

26
Q

Can property damage qualify as a dangerous act in UAM?

A

Yes, if it carries a risk of physical harm to people.

27
Q

What case involved property damage in UAM?

A

R v Goodfellow, where an arson that killed people was considered a dangerous act.

28
Q

In R v Goodfellow, why was the property damage considered dangerous?

A

The arson carried an obvious risk of harm to people in the vicinity.

29
Q

Does R v Goodfellow show that intent to harm property can lead to UAM?

A

Yes, if the act creates a foreseeable risk of harm to others.

30
Q

Can an act against property be sufficient for UAM if there is no risk to people?

A

No, there must be a foreseeable risk of harm to others.

31
Q

Is fear or apprehension enough to qualify an act as dangerous in UAM?

A

No, there must be a risk of physical harm.

32
Q

What does R v Dawson demonstrate about fear and dangerous acts?

A

Causing fear alone, such as in a robbery, is insufficient if it does not carry a risk of physical harm.

33
Q

In R v Dawson, why was the robbery not considered a dangerous act?

A

The victim’s fear-induced heart attack was not foreseeable as there was no inherent risk of physical harm.

34
Q

What is required beyond fear to make an act dangerous?

A

A reasonable person must foresee a risk of physical harm.

35
Q

Can an act causing emotional upset qualify as a dangerous act?

A

No, emotional upset alone does not meet the standard for a dangerous act.

36
Q

What role does causation play in UAM?

A

The defendant’s act must cause the death of the victim.

37
Q

What is factual causation in UAM?

A

The ‘but for’ test – but for the defendant’s act, the death would not have occurred.

38
Q

What case demonstrates factual causation?

A

R v White (but not in UAM context, often applied generally).

39
Q

What is legal causation in UAM?

A

The act must be a significant and operative cause of death.

40
Q

What case illustrates legal causation as ‘more than a minimal cause’?

A

R v Kimsey.

41
Q

What is an intervening act?

A

An event that breaks the chain of causation between the defendant’s act and the victim’s death.

42
Q

How might medical intervention affect causation in UAM?

A

If medical treatment is grossly negligent, it could break the chain of causation.

43
Q

What case discusses medical intervention in the context of causation?

A

R v Cheshire.

44
Q

What does R v Kennedy say about voluntary acts by the victim in UAM?

A

A voluntary act by the victim, like self-injection, may break the chain of causation.

45
Q

Does the chain of causation break if the victim’s actions are voluntary?

A

Yes, if the act is truly voluntary and not coerced.

46
Q

In DPP v Newbury, what was the court’s ruling on foresight of harm?

A

There is no need for the defendant to foresee harm for UAM.

47
Q

What did R v Cato demonstrate regarding causation in UAM?

A

Administering drugs can be seen as the cause of death if the defendant prepared and administered them.

48
Q

Why was R v Cato criticized regarding causation?

A

It linked the defendant’s conduct directly to the victim’s death, which some found overly strict.

49
Q

What did R v Kennedy clarify about causation and drug administration?

A

If the victim voluntarily self-administers drugs, it breaks the chain of causation.

50
Q

How does causation relate to foreseeability of harm?

A

The dangerous act must be a foreseeable risk of harm to be causative in UAM.

51
Q

If someone throws a punch, intending to frighten but not hurt, and the victim dies, can this be UAM?

A

Yes, if a reasonable person would see it as dangerous and it leads to death.

52
Q

If a defendant accidentally causes death during an attempted robbery, is this UAM?

A

Yes, as robbery is an unlawful and dangerous act.

53
Q

If property damage results in a fatal fire, could this be UAM?

A

Yes, if a reasonable person would foresee the risk of harm to others.

54
Q

Can UAM apply if the defendant did not intend or foresee death?

A

Yes, intent to harm or foresee death is not required, only the intent for the unlawful act.

55
Q

If a victim has a pre-existing condition exacerbated by the defendant’s act, is this UAM?

A

Yes, under the thin skull rule, the defendant must take the victim as they find them.

56
Q

What did R v Larkin establish about dangerous acts in UAM?

A

It showed that a reasonable person would see waving a razor as dangerous.

57
Q

What principle did R v Church establish in UAM?

A

The ‘dangerousness test’ – a reasonable person must foresee a risk of harm.

58
Q

Why was the unlawful act in R v Dawson not sufficient for UAM?

A

The robbery only caused fear, not an actual risk of physical harm.

59
Q

How does R v Goodfellow illustrate UAM with property damage?

A

Arson was dangerous as it posed a risk of harm to others nearby.

60
Q

In R v Lamb, why was UAM not applicable?

There was no assault as neither party thought the gun would fire, so no unlawful act.
