I can hazard a guess on this one.
We often have situations like that when people have summary offences. They come to us at the point that they need the pardon. Unfortunately, a lot of people aren't proactive when they try to get a pardon; some of our clients have been eligible for 10 to 20 years and just didn't know the program was in existence.
At lot of the time, through processing the paperwork, we find people have outstanding fines. That fact prevents them from getting the pardon for another three, five, or possibly ten years, so people who have been marginalized already for lack of being able to afford things are then held back for that much longer as well, because everything has to be done under the completion of the sentence. If you have an outstanding fine, you haven't completed your sentence, and therefore your timeframes haven't started. We have seen some people in lower socio-economic circumstances held back for that much longer.
As for a summary offence turning into an indictable offence, that's not my area of expertise.
