Introduction
This advice will consider the potential criminal liability of Priya and Daniel under section 3 of the fictional Park Safety Act 2026. The central issue is one of statutory interpretation: whether the actions of Priya and Daniel fall within the meaning of the words used in the provision. The function of the courts is to interpret the will of Parliament as expressed in the statutory text. However, words can be ambiguous, and so judges have developed several rules and approaches to assist them in this task.
This advice will first outline the main rules of statutory interpretation, including the literal, golden, and mischief rules, as well as the modern purposive approach. It will also explain relevant rules of language, such as the ejusdem generis rule. Following this, the law will be applied to the specific facts of Priya's and Daniel's situations to advise them on their respective legal positions. It will be argued that Priya is likely to have committed an offence, whereas Daniel has a strong argument that he has not.
The Principles of Statutory Interpretation
When a court is faced with a statute, its primary aim is to give effect to the intention of Parliament. The starting point for this is always the words of the Act itself. Over time, distinct approaches have emerged to guide this process.
The Traditional Rules of Interpretation
The most traditional approach is the literal rule, which dictates that the words of a statute should be given their ordinary, plain, and grammatical meaning, regardless of the outcome. As Lord Esher stated in R v Judge of the City of London Court [1892] 1 QB 273, "if the words of an act are clear, you must follow them, even though they lead to a manifest absurdity." An example of this rule in practice is Whitely v Chappell (1868) LR 4 QB 147, where the defendant was acquitted of impersonating a person ‘entitled to vote’ because the person he impersonated was dead and therefore not entitled to vote. The court applied the literal meaning of the words, even though this defeated the purpose of the law.
Where the literal rule leads to a particularly absurd result, one which Parliament could not have intended, the courts may apply the golden rule. This rule is a modification of the literal rule and can be used in two ways. The narrow approach, seen in R v Allen (1872) LR 1 CCR 367, allows a court to choose between two possible meanings of a word to avoid an absurdity. The wider approach, as applied in Re Sigsworth [1935] Ch 89, allows the court to modify the words of the statute to avoid a repugnant outcome. In Sigsworth, the court modified inheritance law to prevent a son who had murdered his mother from inheriting her estate, as this would be an abhorrent result.
The third traditional rule is the mischief rule, which was established in Heydon's Case (1584) 76 ER 637. This rule allows the court to look at the state of the law before the Act was passed to identify the ‘mischief’ or problem that the Act was designed to remedy. The court should then interpret the Act in such a way as to suppress that mischief. A well-known application of this is Smith v Hughes [1960] 1 WLR 830, where prostitutes soliciting from a balcony were found to be ‘in a street’ for the purposes of the Street Offences Act 1959. The court decided the mischief was to enable people to walk down the street without being solicited, and it did not matter whether the prostitute was in the street or above it.
The Modern Purposive Approach
The mischief rule is seen as the forerunner of the modern purposive approach. This approach goes further, requiring the court to consider the overall purpose of the legislation. Rather than just looking for the specific mischief, judges try to ascertain what Parliament was trying to achieve with the law (Bennion, 2005). The House of Lords' decision in Pepper v Hart [1993] AC 593 demonstrated a greater willingness to adopt a purposive approach, as it permitted courts, in limited circumstances, to refer to parliamentary debates recorded in Hansard to determine Parliament’s intention when a statute is ambiguous.
Rules of Language
In addition to these broad approaches, there are also secondary aids to construction, known as rules of language. One of the most relevant for this problem is the ejusdem generis rule (meaning ‘of the same kind’). This rule applies when a statute includes a list of specific words followed by general words. The general words are to be interpreted as being limited to the same kind or class as the specific words. In Powell v Kempton Park Racecourse [1899] AC 143, the phrase ‘house, office, room or other place’ was held not to include an open-air enclosure on a racecourse because the specific words created a class of indoor places.
Advice to Priya
Priya has been prosecuted under section 3, which states: “A person commits an offence if they operate a motor car, motorcycle, van or other vehicle in a public park.” The key issues for Priya are whether her electric scooter is an "other vehicle" and whether she was "operating" it.
The scooter is almost certainly a "vehicle". The term is not defined, but in its ordinary meaning, it is a means of conveyance. The more difficult question is whether Priya was "operating" it. She will argue she was walking beside it, not riding it. The prosecution will focus on the fact that she was controlling a powered machine.
Applying the literal rule, a court would look for the ordinary dictionary meaning of "operate". The Oxford English Dictionary defines 'operate' as to "control the functioning of (a machine, process, or system)". Priya was holding the handlebars, steering the scooter, and had activated its powered "walking assistance" mode. In a literal sense, she was controlling the functioning of the machine. Therefore, a literal interpretation would suggest she was "operating" it.
The golden rule is unlikely to assist Priya. Finding that her actions constitute "operating" a vehicle does not lead to a manifest absurdity that would require the court to depart from the literal meaning. While it might seem harsh, it is not a logically impossible or repugnant outcome.
The mischief rule and the purposive approach are less favourable to Priya. The Act was passed to address "noise and incidents in which pedestrians were injured or narrowly avoided injury by vehicles travelling through public parks." An electric scooter, even at walking speed, is a powered machine that could cause injury if Priya lost control or it malfunctioned. Its presence in the park creates the kind of risk, albeit a low one, that the Act seems designed to prevent. Interpreting "operate" to include controlling a powered vehicle, even while on foot, would promote the statutory purpose of ensuring "Park Safety". A court adopting a purposive approach would likely find that Parliament intended to prohibit the use of such powered devices in parks to protect pedestrians.
Therefore, on balance, it is likely that Priya would be found to have committed the offence. The literal meaning of "operate" seems to encompass her actions, and a purposive interpretation supports this conclusion by focusing on the underlying safety objective of the Act.
Advice to Daniel
Daniel’s situation is different. He was riding an electric bicycle but had switched off the motor and was using it as a conventional pedal bicycle. The key question is whether his bicycle, in this state, falls within the category of "other vehicle" under section 3.
The prosecution would argue that because the bicycle is equipped with a motor, it is a motorised vehicle and therefore falls within the statute. Daniel's counter-argument would rely on the rules of language, specifically the ejusdem generis rule.
Section 3 lists "motor car, motorcycle, van or other vehicle." Applying the ejusdem generis rule, the general words "or other vehicle" should be interpreted in light of the specific words that precede them. The common characteristic, or genus, of "motor car, motorcycle, van" is that they are all vehicles that are propelled by a motor. They are inherently motorised. The question is whether Daniel’s electric bicycle belongs to this class.
Daniel's argument would be that at the time of the alleged offence, his vehicle was not being propelled by a motor; it was being propelled by human pedal power. As such, it was functioning as an ordinary bicycle, not as a motorised vehicle. It did not share the key characteristic of the other items in the list. This is a strong argument. He would contend that the statute is aimed at the use of motorised vehicles, not the mere presence of a vehicle that has the capacity to be motorised. This interpretation is consistent with the decision in Powell v Kempton Park Racecourse, where the nature of the place was key. Here, the nature of the vehicle's propulsion at the relevant time could be seen as decisive.
A purposive approach also supports Daniel’s case. The mischief is noise and danger from vehicles. A standard pedal bicycle, ridden slowly and carefully as Daniel was, does not create the noise associated with motors and poses a significantly lower risk of serious injury to pedestrians than a motor car or motorcycle. By using his bicycle without the motor, Daniel was not contributing to the mischief the Act was designed to prevent. Interpreting the statute to convict him would not seem to further the purpose of the Act.
The prosecution could counter-argue that the Act is intended to be a blanket ban on any vehicle capable of being motorised to avoid difficulties in enforcement (i.e., proving whether the motor was on or off). However, Daniel would argue that the wording "motor car, motorcycle, van" creates a class of vehicles whose primary and essential mode of propulsion is a motor, a class to which a pedal bicycle (even one with motor assistance switched off) does not belong.
Given the strength of the argument based on the ejusdem generis rule, combined with a purposive interpretation, Daniel is in a much stronger position than Priya. It seems unlikely that a court would find that his pedal-powered bicycle falls within the class of vehicles targeted by the statute.
Conclusion
In conclusion, the advice to Priya is that she is likely to be convicted. The literal meaning of "operate" covers her actions, and a purposive interpretation focused on park safety would support a finding of guilt. Her best argument is that she was not using the scooter for transport, but this is weakened by the fact she was still controlling a powered machine.
By contrast, Daniel has a strong defence. His argument rests on the ejusdem generis rule: that his bicycle, when used without its motor, does not belong to the class of motorised vehicles listed in the Act. This argument is reinforced by the purposive approach, as his actions did not create the mischief the Act was intended to remedy. Therefore, it is likely that Daniel would be acquitted of the offence. This demonstrates how the application of different rules of interpretation can lead to different outcomes based on the specific facts of each case.
