two words: Loser pays
I know it will offend do gooder sensitivities and the trial lawyers. But unless there is a downside cost to frivolous lawsuits, you cannot solve the problem. Plaintiffs dont have resources for loser pays. who does? the trial lawyers. who gets a huge payoff if litigation wins. trial lawyers ( litigants themselves are most ofetn not made whole anyway). so who should eat downside cost? He who has both resources and who gets the payoff. So- Loser pays but payer is plaintiff attny. think about it.
