What to do when the only appropriate offence is one with a six month maximum? You need to address this if you think all custodial sentences under 6 months should be abolished.
The thing here is that, minor though the offence is, it occurs in the context of a wider picture of our elected representatives being abused for performing their public service.
Seen that way, there plainly is a need for the courts to retain the power to impose short custodial sentences.
