What constitutes burglary according to s12(1) of the Criminal Justice (Theft and Fraud Offences) Act 2001?

The definition of burglary under section 12(1) of the Criminal Justice (Theft and Fraud Offences) Act 2001 specifically requires that an individual enters a building with the intent to commit an arrestable offence, while also being a trespasser at the time of the entry. This means that mere entry into a building without permission, or without the intent to commit a serious crime, does not constitute burglary.

When the answer identifies the act of entering with intent to commit an arrestable offence as a trespasser, it highlights that the person's unlawful intention is a key component of the crime. This differentiates burglary from other unlawful entries that may not involve the specific intent to commit a serious crime.

Other options do not capture the essential elements of burglary as defined in the legislation. For instance, retrieving lost property does not involve the intention or the classification of being a trespasser in the criminal sense. Remaining in a building after permission lapses also lacks the initial required intent to commit an arrestable offence at the time of entering. Lastly, unlawfully entering a building without committing an offence does not meet the necessary threshold since it does not involve the intent to engage in a serious crime, thereby failing to align with the statutory definition
