Joinder of charges permits charging multiple or alternative offences and conviction for the offence proved by evidence. Where facts leave doubt which of several offences is constituted, the provision permits joinder of charges: the accused may be charged with multiple offences or in the alternative and such charges may be tried together. If evidence shows the accused committed an offence different from the one charged but within those that could have been joined, conviction may follow for the offence shown by evidence though it was not originally charged.
