Judging by the early election season news coverage a California ballot initiative to tax and control cannabis -- for recreational, not just medicinal, uses -- is poised to be one of the most closely watched races of the cycle. So, just what would this ballot initiative do and how likely is it to pass? This post will provide a primer on the law and politics of California's marijuana legalization initiative.
The aspect of the ballot initiative that I've found catches most folks by surprise is what it won't do: make the sale of marijuana legal in the state of California. That's right, despite being billed in media reports as a vote on marijuana legalization, the proposal would not directly legalize the commercial sale, cultivation, or distribution of marijuana. Instead, it would allow local governments to enact ordinances to tax and regulate the commercial sale of marijuana.
In other words, Amsterdam-style marijuana coffee shops would be legal only in cities or counties that wanted to permit them. And, in the cities and counties that did not take up the ballot measure's invitation, buying and selling marijuana would remain illegal. In the near term, it is likely only a relatively small percentage of localities would decide to opt-in and so marijuana would remain illegal to buy and sell in most of the state even if the initiative were to pass.

The new Arizona law criminalizing being undocumented and permitting private citizens to sue for lax enforcement is likely to be struck down in court, according to The New York Times.
When the victims sued the railroad for damages caused by its negligent maintenance, they found the courthouse doors locked. A federal district court held that their claims were preempted by the Federal Railroad Safety Act (FRSA) of 1970, which contained a "preemption" clause that Congress enacted to prevent states and localities from enacting regulations that were inconsistent with the regulations issued by the Federal Railroad Administration (FRA), the federal agency that Congress created to protect citizens from irresponsible railroads.
The basic principle of preemption, that state laws cannot interfere with the operation of the federal government, is an important and uncontroversial feature of our constitutional system. However, over the past 25 years, preemption has become a weapon to defeat state regulations aimed at improving health and safety, as well as state tort suits seeking to compensate victims of malfeasance. Back in 1992, the United States Supreme Court issued a fractured opinion in the
