We already have barratry laws on the books. Someone just needs to enforce them. Advancing disingenuous arguments in court should be an automatic year's suspension.
The standard for permissible arguments in court is having a good faith basis in law or fact, or a good faith argument for extending or changing the law. It's not clear to me that's wrong. Fee-splitting with non-lawyers is the bigger issue. That is impermissible for all sorts of good reasons.
Out of (sincere) curiosity, what are some of those reasons? Thanks.
