In R v. Collins (1973), what was determined as necessary for a conviction of burglary?

In R v. Collins (1973), the court established that for a conviction of burglary, there must be an effective and substantial entry into the property. This means that the entry should not only be physical but also significant in terms of the nature and intention behind it. The decision highlighted that mere presence or minor encroachments do not meet the legal threshold for burglary; rather, there must be an intention to commit a crime within the premises, combined with a genuine and effective entry.

The case emphasized the importance of the defendant's state of mind and the circumstances surrounding the entry. The requirement for the entry to be effective and substantial ensures that there is a clear indication of the perpetrator's intention to commit an unlawful act, which is a crucial element of burglary under the law. Thus, the emphasis on both the physical aspect and the intention behind the entry aligns with the legal definitions and expectations surrounding burglary offenses.
