If Del Beccaro is prepared to a lawsuit tomorrow, be assured, the powers that be already have it.
Unfortunately, I think this may backfire based on the language in the Constitution.
My guess is the focus of the ultimate argument will be on the word "admitted" (vs. active, licensed, etc.).
The argument will probably come down to something like legislative intent. They'll argue that the law was meant to exclude someone who just graduated from law school and immediately wanted to file for A.G. without having the necessary experience as a lawyer. I can see how Brown will win this one. Bummer.
