Something that I would advocate is to require plaintiffs that repeatedly sue on false allegations in order to make the defendant go broke in trying to pay legal fees to actually pay the legal fees themselves. If they continue this behavior, they incur a fine. It's an abuse of the legal system to force someone into bankruptcy.
That was actually my friend's model congress bill this year. It required a plaintiff, upon failure to sue (or if they lose a court battle) to pay all legal fees. However, even this might be abused.
The whole problem is that the legal system is an overcomplicated (because it is), slow, messy, bureaucratic pool of liquefied horsestuff that only big companies (money and workforce) can navigate.
