Mischief can generally be categorized as an offence against someone’s property. It can be either public property or private property. Any change in such property or even its destruction can be classified as an offence of mischief under the Penal Code. Mischief can be of several forms, from acts that do not necessitate a regulatory framework to much more severe acts.
The Offence of Mischief
Section 425 characterizes mischief as a wide variety of offences. This involves maiming and murdering animals, as well as ruining roads, trains, and diverting water. Mischief is committed when a person intends or knows that he is likely to cause wrongful loss or damage to the public or another individual. He may have also meant to destroy or modify any property, or the status of any property, or destroy, lower the utility of any property or adversely affect the property.
The person or owner of the property that is injured or destroyed must suffer wrongful loss or damage. The offender doesn’t need to intend to cause loss or damage if the property is somehow impacted in such a way that its value or usability is impaired. As a result, if the criminal is fully aware that he is likely to inflict wrongful damage or loss, he is guilty of mischief.
Elements of Mischief
To prove the offence of mischief, one has to show that the elements of the offence have been met by the perpetrator. The elements of the offence of mischief are:
1. Destroys the property, diminishes its value/utility or affects it injuriously.
2. With the intent to cause or knows that one is likely to cause wrongful loss or damage to the public or any person.

Cases concerning Mischief
1) Public Prosecutor v Teo Chang Heng  SGHC 315
The respondent had purposefully damaged his spouse’s car with his vehicle. The respondent had consented for her to utilise rental income from their property to pay for a portion of the overdue car instalment payments, which was undisputed. He had also previously contributed to the expense of the car’s repair. Even though the driver had not contributed to the car’s instalment payments or maintenance fees, he was the primary user of the vehicle. The respondent and his spouse were separated at the time of the incident, but he hoped to reconcile. The respondent sped up behind the automobile and tailgated it. He rear-ended it while following it closely down Boon Lay Way and was unable to stop in time. He then decided to drive past it and swipe it on the side. Not satisfied with that, he continued to do two U-turns when he noticed the driver had pulled over to the side of the road and stepped out onto the pavement to check the damage. The respondent then collided with the car from behind, forcing the automobile’s front left wheel to hit the kerb. Before a District Judge, the respondent pled guilty to a charge of mischief, which is punishable under Section 426 of the Penal Code. The prosecution challenged the District Judge’s decision to impose a 10-day jail sentence and 120 hours of community service. They sought a two-week sentence on the grounds that general deterrence and retributive principles demand it. The court determined that the 10-day sentence plus 120-hour CSO was not manifestly insufficient and was suitable in the circumstances. As a result, the appeal against the sentence was dismissed, and the District Judge’s sentence was upheld.
2) Public Prosecutor v Ng Guan Hup  SGHC 170
The three allegations against the respondent stated that the respondent used a syringe to administer a drug to three racehorses belonging to Charles Leck at the Singapore Turf Club in July 2007. The horses underperformed during a race on July 20, 2007, as a result of the drugs. The respondent pled guilty to the accusation and acknowledged the statement of facts without qualification before the district judge on April 8, 2008. He was found guilty of mischief under Penal Code Section 425. The respondent also accepted and agreed to the court taking the other two offences into account when sentencing him. The district court adjourned the trial until 15 April 2008 for sentencing after hearing the mitigating plea. On the postponed date, however, the prosecution notified the court that new evidence had been discovered that put doubt on the respondent’s admissions and guilty plea. The prosecution requested that the respondent be awarded a discharge that did not equate to an acquittal on the three offences under section 184 of the Criminal Procedure Code. The application was denied by the district court, and the prosecution filed an appeal. The court concluded that the facts of the case supported accepting the prosecution’s appeal for a discharge that did not amount to an acquittal. As a result, the court approved the prosecution’s appeal and granted its plea for a discharge not equivalent to an acquittal against the respondent under section 184 of the CPC.
