27 F.4th 657
8th Cir.2022Background
- Mycroft AI (Delaware corp.; open-source voice-assistant) and individual executives Montgomery and Lewis were sued by attorney Tod Tumey and his firm for alleged cyber-attacks, hacking, phishing, and harassment tied to underlying patent litigation.
- Tumey sought emergency injunctive relief (initially a TRO) to stop ongoing cyber-attacks and harassment; he circulated a proposed TRO that, one hour before the hearing, he asked the court to treat as a preliminary injunction.
- At the evidentiary videoconference, Tumey offered testimony and an expert (Webb) describing timing correlations; Webb’s “honeypot” had not forensically identified the perpetrator. Mycroft presented a digital-forensics witness (Perry) who said there was no evidence tying Mycroft to the attacks.
- The district court granted a broad preliminary injunction restraining Mycroft (and those acting in concert) from cyberattacks and from disclosing materials obtained through unauthorized means. The court did not analyze Mycroft’s constitutional or vagueness objections in depth.
- The Eighth Circuit vacated the injunction, holding (1) Mycroft likely lacked meaningful notice and adequate opportunity to prepare after Tumey converted the TRO to a PI on hour’s notice and prevented disclosure of certain alleged evidence at the hearing; (2) the record lacked sufficient evidence linking Mycroft to the attacks, and the other Dataphase factors (irreparable harm, public interest, balance of equities) did not support a PI; and (3) reassignment to a different district judge on remand was warranted because a reasonable person could question the judge’s impartiality.
Issues
| Issue | Plaintiff's Argument (Tumey) | Defendant's Argument (Mycroft) | Held |
|---|---|---|---|
| Adequacy of notice and opportunity under Fed. R. Civ. P. 65(a) | Immediate relief required; conversion to PI was appropriate to halt ongoing attacks | One hour’s notice to convert TRO to PI and court limits on disclosure denied meaningful opportunity to prepare and defend | Court: Notice was likely insufficient; PI issuance was procedurally dubious and prejudicial to Mycroft |
| Likelihood of success / nexus to defendants | Temporal proximity and testimony show attacks rose after litigation events; Tumey has evidence (some withheld) tying Mycroft | No forensic evidence ties Mycroft; alternate actors plausible; expert says no attribution possible | Court: Temporal correlation alone is inadequate; record lacks sufficient nexus to Mycroft; clear error to grant PI |
| Irreparable harm / adequacy of money damages | Cyber-attacks and harassment cause ongoing, non-quantifiable harm to safety and reputation | Alleged harms are quantifiable and compensable by money damages | Court: Plaintiff failed to show irreparable harm; money damages appear adequate |
| Reassignment on remand for impartial judge | (Implicit) No recusal needed; prior rulings appropriate | District judge’s conduct and rulings reflect antagonism; impartiality could reasonably be questioned | Court: Reassignment warranted; remand to different judge instructed |
