If an individual was convicted of a felony (cpc 12020) and could at the time prove he was exempt from this section, by virtue

I know of no occupational code section that carries a penal code exemption in the state of California.

Addendum to previous question, no prior strikes or citations of any kind, the trial lasted almost 3years, no gun,no fingerprints

Must be me, but I don't know what the question is.

So today I got an infraction, it was for possession of marijuana does that appear on my criminal record?

Yes.

What criminal or civil recourse do I have ? I want to press charges of assault, but have been told no DA would pick up the case.

With criminal, file a charge with the authorities. As to civil, file a small claims for battery.

If I recover from a slip and fall can I still sue?

Yes.

I currently havd edrug court and i have given some dirty tests but i missed a testdue to a funeral

A "few" dirty tests and a missed test. ? Probably not given a break for a bs reason.

What does 'default vacated' means?

The default was vacated for some reason. Ask the clerk.

Do the restrictions get any less on house arrest as i prove myself to probation as the months go on?

As a general answer, no, they do not. That is like getting points for what you are supposed to do.

Yes,, ex post facto has nothing to do with it.
