In so many ways--AI, controlling your client, representing your kid's girlfriend's mother for free. Here is the district court order.
Note the apparent surprise about the severity of the sanctions against the attorney (much more money than other courts have imposed) and the sanction (dismissal) against the client. Courts are reluctant to bring the hammer down with severe sanctions. FRCP 11(c)(4) says the sanction "must be limited to what suffices to deter repetition of the conduct or comparable conduct by others similarly situated." Sanctions are not intended either to compensate the injured party or the punish the offending party. But the combination of an increase in "performative litigation" and the prevalence of AI may push courts to be harsher--whatever they are currently doing is not deterring.
