I think that's probably too blunt an instrument since every case stands on its own. The courts have developed a meaningful test for what is a vexatious litigant. I don't think you need to recreate anything out of whole cloth. There's something already there. It always does take into account the nuances and the circumstances. I think that's probably appropriate.
I would not want to see an enormous amount of resources wasted for nothing, but again as I said, I'm concerned about cutting people off from effective redress.
