That is the only way to address the issue of bringing frivolous civil lawsuits. Change it to lawyers only bringing lawsuits they think they can win.
There are many states, including NC, where the charging party are assessed legal fees of the defending party. The problem is that federal courts have no such provisions, so attorneys will go thru amazing hoops to bring cases to federal courts. The legal system in the USA is the most corrupt, convoluted, twisted, and byzantine structure imaginable. I am not even a lawyer and I know it. I cannot imagine how jaded, burned out, and dispirited it must make a young da or aspiring champion of justice who enters that profession. I have never met a cop who has any experience working with these people who has anything but disdain in general for them, and I am no fan of cops as an institution, either. The whole thing is rotten.
EDIT: Heh, after typing that jeremiad, the thought entered my head "well, what about Daniel? You really think the courts/legal system in Babylon were models of decorum, justice, integrity, uprightness and not cesspools of avarice, revenge, greed and personal acquisition?" Reminds me that wherever I am, my goal cannot be to reform the structures. Too big a job for me. If I can reform ME and try to act like I wish everyone would act, that is the only "win" that is likely to go down in my column. Don't expect integrity in a world full of liars and thieves, and don't pump your own integrity, Eddie. If it is real, people will see it and notice.
I am all the time trying to play with the pros, when my proper place is in the Pop Warner leagues. Hard for me to remember, but it brings peace when I can.
Yes, the legal system is gamed for the legal professionals. It is what you expect in a corrupt society.
