Business Court Retains Authority to Reconsider Remand After Plaintiff Amends to Eliminate Jurisdictional Claims

In In re ColossusBets Limited, the Fifteenth Court of Appeals denied mandamus relief to defendants challenging the Business Court's remand order after plaintiff Jerry Reed amended his lottery-rigging claims to eliminate all allegations implicating the court's statutory jurisdiction over internal affairs and governance. The court framed the central issue as whether removal to the Business Court operates as a "one-way door" that prevents reconsideration even when a plaintiff eliminates all jurisdictional predicates through amended pleadings.

Fifteenth Court Holds 'Action' Means Entire Lawsuit, Not Individual Claims, for Business Court Removal Eligibility

The Fifteenth Court of Appeals denied mandamus relief to relators seeking to remove derivative claims filed in December 2024 from a divorce action commenced in July 2024, holding that the term "civil action" in the Business Court Act's effective-date provision refers to the entire lawsuit—not individual claims added later—and thus the Act does not apply to any part of a case filed before September 1, 2024. The decision reinforces In re ETC Field Services and rejects arguments that later-added commercial claims could be severed and removed as a separate "action."

Amended Petition Adding Publicly Traded Party After September 1, 2024 Does Not 'Commence' New Action for Business Court Jurisdiction

The Fifteenth Court of Appeals denied mandamus relief to Kimco entities seeking to keep their case in the Business Court after being added as defendants via third-amended petition in September 2024, holding that a civil action 'commences' when originally filed, not when an amended petition adds a publicly traded company. The court rejected relators' argument that adding a publicly traded defendant after the September 1, 2024 effective date triggers Business Court jurisdiction, reaffirming its holding in In re ETC Field Services that removal or amendment does not commence a new civil action.

Removal Statute Does Not Apply to Pre-Effective Date Cases: Business Court Lacked Authority to Accept 2017-Filed Action

The Fifteenth Court of Appeals denied mandamus relief in In re ETC Field Services, holding that the Business Court properly remanded a 2017-filed breach of contract action because HB 19's removal provisions apply only to "civil actions commenced on or after September 1, 2024"—and removal transfers rather than commences an action. The court rejected ETC's attempt to remove a seven-year-old case just months before trial, establishing that the Legislature's choice of "commenced" forecloses removal of cases filed in district court before the Business Court's creation.
