Obviously you mean plaintiff, but nevertheless I don't much like it, nor do I see it being practical.

Without contingency fees, poor people cannot afford to sue. That's a bad idea, since it allows tortfeasors to do bad things to poor people with impunity, as long as they avoid criminal prosecution.

And not every case can support punitives, you know.

I have yet to see a balanced argument for tort reform, I'm afraid, and I don't see serious problems with the status quo.
