Mr. Chair, there are two comments that should be made in response to the question.
The general intent is that if a non-commissioned member is sentenced to the punishment of detention, they are reduced in rank to private for the period of the detention, and then their rank is restored. Let's take the hypothetical example of a sergeant who was sentenced to detention and reduced in rank to private. They would continue to be paid, but at the private level while they served that sentence, and once the sentence was done they'd go back to their previous rank.
What clause 20 is actually referring to is the specific case where there's an intermittent sentence, which is, you will recall, one of the new sentencing options provided for in the bill. This particular clause says “until the sentence of detention is completed”, which is meant to address the situation where you may have a person who is sentenced to detention but is serving it intermittently—over the space of several weekends, for example—just to avoid any uncertainty about what their status is during the period when they are not actually in detention.
Let's say, again, a sergeant is sentenced to detention. They serve the sentence intermittently. During the period when they are in custody, they are a private. But if there isn't a rule providing clarity, there'd be massive confusion if they showed up at the armoury in the middle of the week before they went back to serve their detention again on the weekend. What is this person's rank? What is this person's status?
So this is just meant to provide clarity. While they're undergoing intermittent sentence, they're a private throughout that period.
