Why does legislation have to be some confusing. So I get that certain parts of the law have been signed, but what about the affiliate tax? Is that now the law.

Why does legislation have to be some confusing. So I get that certain parts of the law have been signed, but what about the affiliate tax? Is that now the law. The article says "Brown announced signing eight separate pieces of that package Wednesday, though not the main spending plan itself. The online sales tax law, AB 28 1x, would seek to force online retailers who have no physical presence in California, such as Amazon.com, to collect the same levies as bricks-and-mortar stores." The use of "would seek to force" seems to suggest this part hasn't passed yet. So the real question is did it pass or not?
