"It cannot be right that the court's power is limited to the six months' maximum imprisonment for the distinct criminal offence. That would treat the breach as if it were a stand-alone offence, which at the time when it was committed did not amount to a breach of the court order. In reality, the breach is a distinct offence in its own right, created by stature and punishable by up to five years' imprisonment. We therefore reject the submission that it was wrong in principle for the judge to have imposed a custodial sentence where for the instant offence of drunkenness a maximum sentence would have been a fine."
