Plaintiff Sues Sen. Markwayne Mullin and Co-Defendants in Civil Action

A federal court issued a written opinion on April 20, 2026 in Tornike Daushvili v. Markwayne Mullin et al. The docket number and court of record are not yet confirmed in Juryvine's files, but the case is active and the opinion is the first substantive ruling on record.

Daushvili is the plaintiff. Mullin — the U.S. Senator from Oklahoma — is the lead defendant.

The 'et al.' signals at least one additional defendant, though the full defendant list has not been confirmed.

The key legal issues driving the case are not yet detailed in available filings. What is clear is that a court found the matter worth a written opinion, which means at least one contested legal question was ripe enough to decide. That opinion is the controlling document right now.

The judge assigned to the case has not been confirmed. No filing date for the original complaint is on record. Both gaps limit what can be said about the procedural posture — whether this opinion resolved a motion to dismiss, a summary judgment bid, or something else is unknown pending full docket access.

Daushvili suing a sitting U.S. Senator is the headline fact. Federal suits against sitting members of Congress face threshold questions about the Speech or Debate Clause, which shields legislators from civil liability for acts taken in their official capacity.

Whether that defense was raised or addressed in the April 20 opinion is the first thing to check in the actual ruling.
