> that it justifies taking away their right to practice law in a given state.
This seems a little weird. As far as I understand it, no one has a right to practice law.
There is a privilege that can be acquired, it one meets the requirements. If you somehow got through without meeting those, or if you start to fail to meet those... time for a new career.
> We don’t know the full situation here, but a personal injury case against a bankrupt airline for striking someone in the knee with the serving cart seems remediable?
I don't know about this particular case, but many cases and circumstances can be a "one shot at it" scenario. You fuck it up, it's tossed and you can't refile. There are many reasons and details, any of which might be messed up by a lawyer relying on a silly chat program to draft motions. One might miss an absolute deadline. It might be dismissed with prejudice. Appeals might be exhausted. This could even be true of the case in question.
In some cases, it might even be true if it was a criminal trial and your defense attorney was incompetent, that you don't get a chance to appeal. In California, I think, those are Marsden cases (someone correct me if I'm wrong). For those, you have to raise an objection during the trial.
So, if someone found out that ChatGPT gave their lawyer bad advice the day after their conviction... well, oops. No appeal for you.
I'll say it again. I do not want to live in a world where law license proceedings are decided on a "what's fair to the bad lawyer" basis. No one has a right to be a lawyer, if you're bad at it there are plenty of other occupations you might make a living with where incompetence doesn't threaten so many lives and livelihoods.
