Which type of offence can be tried either as a summary conviction or an indictable offence at the Crown's discretion?

The correct answer is hybrid offence. A hybrid offence, also known as a dual offence, is a category of crime that allows the Crown prosecutor to choose whether to proceed with the case as a summary conviction or an indictable offence. This flexibility enables the Crown to assess the specifics of the case, including the severity of the crime and the circumstances surrounding it, and decide the most appropriate legal route for prosecution.

This capability can greatly influence the potential penalties and the legal processes involved. For example, if the Crown decides to prosecute a hybrid offence summarily, it typically results in a quicker resolution and generally lighter penalties. Conversely, if it is pursued as an indictable offence, the potential consequences may be more severe, and the legal process can take longer due to the more complex procedures involved.

Other types of offences such as minor offences, summary offences, and indictable offences do not possess this characteristic. Minor offences are often less serious violations but do not fall under the dual classification. Summary offences are dealt with in a more streamlined manner with limited penalties and are not flexible to be treated as indictable. Indictable offences are typically more serious crimes that are always treated as such, without the option for summary handling.
