I'm thinking along the lines of Backgammon as well. If you're a citizen of UCAS, or have a SIN from a nation or corp that gives you most of the same rights in UCAS territory, you will get most of the rights we have today.
I guess that means no searches without probable cause, a maximum of 72 hours(?) detention without a trial. They probably need permission to wire(less)tap your data, or at least probable cause again. The nature of abundant and easy hacking makes it necessary that LS and even CorpSec have great leway in tracking down suspected hackers and even invading their commlinks to gather evidence or protect their intellectual property.
LS have the right to access your SIN at any time, but probably not look at your Porn Sims, unless they have reason to believe that you have illegal programs or an illegally modified Sim Module.
And any Sammie walking down the street with suspcious SMG bulges in his his Lined Coat can probably be required to show his "items."
But remember, the Star doesen't male the rules, it's the politicians (and their corporate sponsors/lobbyists) that does. Rules will be in theory very similar to today's law, with a few changes that look minor on paper but can have great repercussions on some individual and favor corps.
If the Star bend/break the rules too much some watchdogs will notice and they risk loosing their deal to another sec group.
Criminal SINners have very few rights, and probably can't own licences for any restricted items, vote, recieve free medical service (if any) or social security. The only benefit is that the Star can't just kill you as you're considered a (meta)human being. Well, unless they don't get caught
