Court of Appeal (Criminal Division) ยท Edmund Davies LJ gave the judgment of the Court of Appeal (Criminal Division).
Facts
The defendant, after drinking, climbed a ladder at night to the open bedroom window of a young woman's room. She woke to see him at the window, took him for her boyfriend and had intercourse with him before realising her mistake. He was charged with burglary with intent to rape under section 9(1)(a) of the Theft Act 1968. The issue was whether he had entered the room as a trespasser or only after she invited him in. He was convicted.
History
The defendant was convicted of burglary with intent to rape and appealed, arguing that the jury had not been properly directed on whether he entered as a trespasser, since the woman may have invited him in before he entered.
Issue
Whether a defendant is guilty of burglary only if he made an effective and substantial entry into the building as a trespasser, knowing or being reckless that he was entering without permission, and whether the jury had been properly directed on that.
Held
Appeal allowed; conviction quashed because the jury had not been properly directed on whether the defendant entered as a trespasser, knowing or reckless as to that.
Ratio
- For burglary under section 9(1)(a) of the Theft Act 1968 the defendant must have made an effective and substantial entry into the building as a trespasser, and must have known that he was entering as a trespasser or been reckless whether he was.
The judgments
Edmund Davies LJ (lead)
Edmund Davies LJ gave the judgment of the court. He held that the entry must be effective and substantial and made as a trespasser, with knowledge or recklessness as to being a trespasser, and that the jury had not been properly directed on whether the entry was made before the woman invited him in. The conviction was therefore quashed.
Key reasoning
- Entry as a trespasser involves a mental element: the defendant must know that he is entering without the consent of the person entitled to give it, or be reckless as to whether he has that consent.
- The jury had not been asked to consider whether the defendant had made an effective and substantial entry before the woman invited him in, and whether at that point he knew or was reckless that he was a trespasser, so the conviction was unsafe.
Where it fits in the module
Collins is a foundational case for Topic 5 (Property Offences) on burglary. It defines the mens rea of trespass under section 9 Theft Act 1968 and contrasts with later cases such as Jones and Smith [1976] (where entry beyond permission was held to be trespass) and Walkington [1979] (conditional permission). It illustrates the tension between subjective and objective approaches to dishonesty and permission in property offences, a theme running through the module alongside cases like Ghosh, Ivey, and Gomez.
Criticisms
- The purely subjective test allows a defendant to escape liability for burglary based on an unreasonable or even delusional belief in permission, which may undermine the protection of property rights.
- The decision creates a discrepancy between the mens rea for trespass in burglary (subjective) and the mens rea for the underlying offence (which may be objective), leading to doctrinal inconsistency.
- Later courts have struggled to reconcile Collins with the principle that a person who enters conditionally and exceeds the condition becomes a trespasser, as in Jones and Smith.
- The reliance on recklessness as an alternative to knowledge introduces uncertainty about what constitutes recklessness in this context, especially after the reformulation of recklessness in G and R [2003].
