So I will start off with accepting that it is my responsibility and I know I should have paid for my rego on time.
Back story is: I moved houses and forgot to update my address. Months later I get pulled over for not having a registered vehicle. I obviously never got renewal letter and totally forgot. The registration was actually cancelled so I couldn't even pay for it. Had I not been pulled over I still probably wouldn't have realised. Was fined for non-rego and not updating address. Accepted both and paid for both.
I realised… I better check if I have any other fines that were sent to old address. Called fines Victoria and unfortunately there is a fine outstanding. My partner had been caught speeding, so I sent a nomination for that fine. However, attached with this speeding fine is a fine for driving an unregistered vehicle.
I have sent a review request asking for this to be waived with no success. Surely you can't be fined twice for the same reason?
Should I take this to court and what are the chances the magistrate would decide in my favour? I have no other traffic convictions for probably over 5 years.
//edit to add:
Paid the fine as it seems pretty unanimous that it'd be a waste of time.
You're lucky you got pulled over. Would have cost a lot more if you had an accident and found out that you had no TAC insurance and possibly no cover for property damages. You can get fined many times for driving the same unregistered vehicle, your partner should have checked the registration.
