If it hasn't worked in TX I don't see why it would work in CA.It depends on exactly what the SC
It depends greatly on what the exact case is. If it was an attempt to shield abortion clinics from lawsuits, then locus standii could not be achieved. However, if it was an attempt to overturn the abortion law (which I believe it was), then locus standii is a breeze.
I suggest the legal attack would be to challenge the proposed (California) law banning the sale of handguns. Locus standii would be easy, and prior decisions would likely have the SCOTUS strike down that law.
I decided to become a computer developer, but I might have become a lawyer to good effect. :^)
Newsom said he directed his staff to draft a bill that would allow private citizens to seek injunctive relief “against anyone who manufactures, distributes, or sells an assault weapon or ghost gun kit or parts in the State of California.”
There is no proposal to ban the purchase of handguns. If you find one I’d like to see it.
