An offence that may be tried on indictment. Most serious common-law offences are indictable (e.g. murder, rape) and many are created by statute. When a statute creates an offence without specifying how it is to be tried, it is automatically an indictable offence. The most serious indictable offences (indictable-only offences) may only be tried in the Crown Court. However, some less serious indictable offences (offences triable either way) may be tried either in the magistrates' court or in the Crown Court.
