Background
Svyatoslav Mangushev filed a petition for a writ of certiorari seeking Florida Supreme Court review of a final order. The matter arose from proceedings bearing lower-tribunal numbers 4D2025-2201 and 062017CA000351AXXXCE.
The court treated the certiorari petition as a petition invoking its authority to issue all writs. Justice Tanenbaum stated separately that the court had initially treated the filing as a notice invoking review jurisdiction, but that procedural account appeared in his concurrence rather than in the court’s dismissal order.
The Court’s Holding
The Florida Supreme Court dismissed the petition for lack of jurisdiction. It held that Mangushev had not identified an independent jurisdictional basis permitting the court to exercise its all-writs authority, and that no such basis was apparent from the petition. The court also stated that it would not consider a motion for rehearing.
Chief Justice Couriel and Justices Labarga, Muñiz, Grosshans, and Francis concurred in the dismissal and its rationale. Justice Barrios concurred only in the result. Justice Tanenbaum also concurred in the result, writing that dismissal was proper because the court lacked review jurisdiction but criticizing the court’s invocation of “all writs jurisdiction” as constitutionally inaccurate and unnecessary.
Key Takeaways
- The Florida Supreme Court’s all-writs authority does not supply jurisdiction when a petition identifies no independent basis for the court to act.
- The court dismissed Mangushev’s petition rather than reaching the merits of the underlying final order.
- Justice Barrios concurred in the result, while Justice Tanenbaum separately argued that the court should have dismissed solely for lack of review jurisdiction.
Why It Matters
The order underscores that a request for an extraordinary writ cannot substitute for a recognized basis of Florida Supreme Court jurisdiction. A petitioner must identify an independent source of jurisdiction before the court may use its all-writs authority in aid of that jurisdiction.
Justice Tanenbaum’s concurrence highlights an internal disagreement over terminology and analytical method: although every justice agreed that dismissal was warranted, not every justice joined the court’s stated rationale.
