Wow, I read that whole thing (ok, i skimmed over the historical section on the legislative statues of California since the 19th century), here (on the last two pages btw) is the essence
So, plant limits are unconstitutional, and the affirmative defense afforded by CUA 1996 (Prop 215) is still the law. Reasonable limits for meeting the patients needs are to be observed in court. These limits may be set above the 'norm' by a physician.
SB 420 (Section 11362.77) is still valid insofar as the optional identification program is concerned. One may elect to enroll and be provided a document to provide law enforcement so as to be immune from arrest. 12 immature OR 6 mature plant, and 8 ounces of dried flowers are to be considered normal and fully protected under state law.
more than 6/12 watch out for the feds?
Technically, ANY number you can watch out for the Feds.
Practically speaking, you go more than 6/12 they can still bust you and fight it out later. Maybe you are right and win - then again, maybe not.
Just as there are no guarantees you are in the clear, there are no guarantees that you are not, either.
It's a helpful decision, but it's not the be all and end all. If you push your grow beyond all reason, they'll nail you for it. If you push it beyond 6/12, they may choose to nail you for it anyways and let the court decide. You'll be paying lawyers and have your plants and stash seized in the interim. Then there is bail and bail conditions to deal with too. Not a happy situation to be placed in.
What is beyond all reason varies from patient to patient. It is situational, to be sure.
In any event, there is no "opting in" to the limits by applying for a card. That argument was rejected. Accordingly, a card is wise to obtain. It only benefits you by providing you with protection against arrest. Meanwhile, the card does not harm or restrict you from maintaining your CUA defense, such as it is, in all of the circumstances. That's the point to take away from this.
Remember, Kelly had the defendant busted with seven mature plants instead of six; Kelly has in possession of 12 ounces of MJ instead of 8 oz. These were pretty small "overages" and could easily have fallen within the "boundaries of reason".
If you think the Cali Supreme Court just endorsed your transporting a duffle bag full of 30 lbs of weed and 300 plants in your grow op -- all for your "personal use" - guess again.
The CUA provides no protection from arrest; it simply provides a potential defense at trial.
SB420, with a card, provides protection from arrest if one falls within the plant and weight limits. That has not changed under People v. Kelly -- to the contrary, that protection was explicitly preserved..
