R v Miller
Factual and Procedural Background
The Appellant had been sleeping on a mattress in a house where he had been staying for several weeks. After returning from an evening out, he lay on the mattress, lit a cigarette, and fell asleep. He later awoke to find the mattress smouldering. Instead of attempting to extinguish the fire or summoning assistance, he moved to another room and went back to sleep. The fire spread and damaged the house.
The Appellant was indicted in The Crown Court for arson contrary to section 1(1) and (3) of the Criminal Damage Act 1971. He did not testify, and the facts contained in his police statement were undisputed. A jury convicted him and he received a six-month custodial sentence.
On a single ground of law—that the admitted facts disclosed no offence—the Appellant appealed to the Court of Appeal (Criminal Division). That court dismissed the appeal but certified a question of general public importance. Leave to appeal to the House of Lords followed, culminating in the present judgment.
Legal Issues Presented
- Whether, under section 1(1) and (3) of the Criminal Damage Act 1971, the offence of arson is made out when a person accidentally starts a fire but, on becoming aware of it, intentionally or recklessly fails to take steps to extinguish the fire or prevent damage to property belonging to another.
Arguments of the Parties
Appellant's Arguments
- The undisputed facts amounted only to an accidental ignition followed by inaction; this, it was contended, did not constitute the actus reus of arson because the statute requires a positive destructive act.
- An omission can found liability only where the legislation expressly imposes a duty, which (the Appellant argued) section 1 does not.
Respondent's Arguments
- Once the Appellant created the dangerous situation, his subsequent failure to act, coupled with the requisite mental state, satisfied the statutory elements of arson.
- An offender who becomes aware of a risk he has created and chooses to ignore it is reckless within the meaning of the Criminal Damage Act 1971.

| Judge Commissioner [1969] 1 Q.B. 439 (Continuous-Act Principle) | Concept that a single criminal act may be viewed as continuing over time. | Referenced in academic debate; contrasted with the “duty/responsibility” analysis ultimately favoured by the House. |
Court's Reasoning and Analysis
Judge Diplock, delivering the leading opinion, emphasised that arson under the Criminal Damage Act 1971 is a “result-crime”: the offence is complete only when property belonging to another is destroyed or damaged. The analysis therefore extends over the period from the initial act that created the danger until the damage is complete.
The Court rejected the idea that criminal liability requires a further positive act after ignition. Once an accused creates a dangerous situation, a responsibility arises to take reasonable steps—personally or by summoning assistance—to avert or mitigate the harm. Failure to do so can constitute the conduct element of the offence.
The Court considered two doctrinal routes—(1) treating the conduct as a single continuous act and (2) recognising a duty (or responsibility) triggered upon awareness of the risk. Both lead to liability, but the latter was preferred for its clarity in jury directions.
Applying Caldwell, the House held that recklessness is established where the risk would have been obvious to anyone who gave thought to it and the accused either failed to consider the risk or, having considered it, proceeded regardless. Here, upon awakening to the smouldering mattress, the Appellant was aware—or ought to have been aware—of an obvious risk to the house and consciously chose to do nothing.
Accordingly, the certified question was answered in the affirmative: the statutory elements of arson are satisfied when an individual, having accidentally caused a fire, recklessly omits to act to prevent ensuing damage.
Holding and Implications
APPEAL DISMISSED; CONVICTION AFFIRMED.
The certified question of law was answered “Yes,” confirming that an omission to act after creating a dangerous situation can constitute the conduct element of arson when coupled with the requisite mental state. Costs incurred by the Respondent, represented by Company A, are to be paid from central funds under the Costs in Criminal Cases Act 1973.
Implications: The decision clarifies that under English criminal law a person who, by his own act, creates a hazardous situation must take reasonable steps to prevent foreseeable harm. Failure to do so—where the risk is obvious—suffices for liability under section 1 of the Criminal Damage Act 1971. The ruling strengthens the principle that omissions can ground criminal liability when a prior act has generated the danger, providing authoritative guidance for future cases on arson and analogous result-crimes.
