Arizona used car salesman Van Flury is a vexatious litigant, no doubt. He has filed 50 lawsuits over the last decade, and now a judge says he needs permission to file another one. But vexatious litigation laws ought to be unconstitutional, since we have a right to petition government. And if that right isn’t ironclad, the Fourteenth Amendment (due process clause) means it ought to apply to everyone, not just to pro se litigants. My take is that blocking access to the courthouse door allows for judicial bias against pro se litigants to go unchecked.
