Act Summary
The Criminal Damage Act 1971 is the leading piece of legislation, concerning offences involving damage to property.
1. Why was it introduced? (Political/Sociological Context)
In April 1969, the Law Commission released a working paper and subsequently in 1970 – a report, which aimed to review the criminal law on the offences of damage to property. Prior to the enactment of the Criminal Damage Act 1971, the criminal law on damage to property was covered by the Malicious Damage Act 1861, which survived for over 100 years. In the 1960s and 1970s, the Law Commission was running a programme which envisaged the codification of criminal law.
In the run-up to the adoption of the Criminal Damage Act 1971, malicious damage offences were very prevalent among juveniles and in the cases of arson, well over half of the convicted persons were juveniles. Furthermore, there were very few cases which called for heavy sentences such as life imprisonment. Yet, there were no less than 25 provisions of the Malicious Damage Act 1861, under which the maximum sentence of imprisonment was 14 years or more.
2. What was the aim of the Act? (Legal Context)
In the report, the Law Commission concluded that the offences and penalties under the Malicious Damage Act 1861 were extremely complicated. Further to that, the Law Commission found that the Malicious Damage Act 1861 was unsatisfactory in many aspects, e.g. there were too many offences, the variety of penalties were excessively wide, there were overlapping offences between the Act and other pieces of legislation and the mental element required in the offences was described in technical language, which made it difficult to understand. As the majority of the cases under the Malicious Damage Act 1861 were dealt with by the magistrates’ courts, it was deemed necessary to create a simple and straightforward law, founded on more rational provisions. For instance, under the Malicious Damage Act 1861, there were multiple classifications of the offences of damage to property, e.g. according to the type of property damaged, the method used, the status of the offender, the circumstances of aggravation, the offender’s object and the extent of damage done. This detailed classification was abandoned in the Criminal Damage Act 1971 in favour of a broad statement of the conduct to be punished, so that there is one offence to cover the whole field of damage.
3. What main changes did it make to the law?
The Act consolidated the definition of property that is capable of forming the subject matter of criminal damage. While in the Malicious Damage Act 1861 there was a division between criminal damage inflicted on a number of objects such as buildings, goods, machinery, corn, trees, vegetable products, fences, mines, sea and river banks, etc., under the Criminal Damage Act 1971 this was formulated as simply “tangible property” under s. 10(1).
S. 1(2) of the 1971 Act creates the new offence of aggravated criminal damage. It includes all elements of general criminal damage but with the additional element of being reckless as to creating danger to life.
S. 1(3) of the 1971 Act draws a distinction between damage by fire and damage by other means. The former is treated with more severity and is charged as arson and punishable by life imprisonment. The reasoning behind this provision is that causing damage by fire has always been regarded with abhorrence. Further to that, life imprisonment is necessary because most people who cause damage by fire are mentally unbalanced, yet they do not qualify for committal to hospital. By giving the flexibility of life imprisonment, it was made possible to keep such individuals in detention for as long as it proves necessary.
Ss. 2 and 3 of the 1971 Act clarify the position on two subsidiary offences – threats to commit criminal damage and possession of anything with the intent to destroy or damage property. Prior to the Criminal Damage Act 1971, threats were only limited to written threats, but now cover all means of threatening. Also, threats to destroy were limited to specific types of tangible property, but now cover all types of tangible property. As far as possession of items with the intent to destroy is concerned, the changes were in the same line of thought. The Malicious Damage Act 1861 used to provide a list with prohibited items, whereas the Criminal Damage Act 1971 makes it illegal to possess anything with the intent to destroy property.
S. 5(2) of the 1971 Act sets out a specific defence against charges for criminal damage, separate from the general self-defence excuse available for all offences involving violent acts. Under the Act, the defendant has a lawful excuse for criminal damage if the person who was entitled to consent to the destruction had consented to it or would have consented to it, had they known the circumstances or the person who committed criminal damage did so in order to protect his property and his actions were reasonable, given the circumstances.
S. 4 significantly simplifies the punishments for acts of criminal damage. Under the 1876 Act there were a number of sections attracting a sentence of life imprisonment, 8 sections, carrying a maximum sentence of 14 years imprisonment and generally, the maximum sentences of imprisonment used to vary widely in an irrational manner. Under the 1971 Act this was simplified and for arson, the maximum sentence is life imprisonment, whereas for the other offences under the Act – no more than 10 years.
2026 update:
Recklessness: R v G [2003] UKHL 50
If this page discusses the mens rea for criminal damage, students must understand that the meaning of “recklessness” under the Act was fundamentally changed by the House of Lords in R v G [2003]. This case overruled the earlier decision in R v Caldwell [1982], which had applied an objective test for recklessness. The law now applies a subjective test: the defendant must personally have foreseen the risk of damage and unreasonably decided to take that risk. A defendant who genuinely did not realise there was a risk of damage cannot be convicted on the basis that a reasonable person would have realised. This is particularly important in cases involving young defendants or those with limited mental capacity.
Sentencing
Sentencing law has been consolidated by the Sentencing Act 2020, which is now the primary source for sentencing procedures and powers. The maximum penalties under the Criminal Damage Act 1971 remain unchanged: life imprisonment for arson or offences involving intent to endanger life (Section 1(2)), and up to 10 years for other offences on indictment. The Sentencing Council has published guidelines for criminal damage offences which courts must follow when determining sentences.
Threshold for “Damage”
Case law continues to develop on what constitutes “damage” to property. The courts take a broad approach, and damage can include temporary impairment of value or usefulness even where there is no permanent physical harm. Students should be familiar with cases such as Hardman v Chief Constable of Avon [1986] on temporary damage and A (a juvenile) v R [1978] on the cost of restoration.
2026 update
The Criminal Damage Act 1971 remains in force as the leading legislation on damage to property in England and Wales. Its core provisions are unchanged. However, students should note the following developments.
The mental element: R v G [2003]: The above discussion notes that one aim of the 1971 Act was to replace the technical language describing the mental element under the Malicious Damage Act 1861. However, the interpretation of “recklessness” under the 1971 Act was itself the subject of significant judicial development. In R v Caldwell [1982], the House of Lords applied an objective test, meaning a defendant could be convicted if a reasonable person would have recognised the risk, even if the defendant personally did not. This controversial approach was overruled by R v G [2003] UKHL 50, which restored a subjective test. The law now requires that the defendant personally foresaw the risk of damage and unreasonably chose to take it. This is fundamental to understanding the mens rea for offences under Section 1.
Sentencing: The above discusses how the Malicious Damage Act 1861 had excessively wide penalties, with 25 provisions carrying maximum sentences of 14 years or more. The 1971 Act’s maximum penalties remain unchanged (life imprisonment for arson or endangering life under Section 1(2); up to 10 years on indictment for basic criminal damage). However, sentencing practice is now governed by the Sentencing Act 2020 and Sentencing Council guidelines, which provide structured guidance to courts on appropriate sentences based on culpability and harm.
