After a case was transfered to the District of Columbia, the Fifth Circuit granted mandamus relief about that transfer in In re Clarke, focusing on the district court’s analysis of the “local interest” factor
[E]vents giving rise to the suit can be separated into two categories: The first concerns individual traders who purchased contracts on the marketplace. Five of them are based in Austin, bought their contracts from Austin, and have been harmed in Austin. The second category deals with marketplace service providers—Aristotle and PredictIt. Based in D.C., they “expended significant resources to assist Victoria University in developing and operating the PredictIt Market” and “will be forced to incur massive administrative, labor, time, and other costs if forced to liquidate pending contracts prematurely.”
Given those events, there is an obvious connection between the facts giving rise to this case and the Western District of Texas. And, if we assume that Aristotle’s and PredictIt’s development and operations activities occurred in D.C., there is also a factual connection with D.D.C.
Additionally, the effect of this suit is completely diffuse. Should plaintiffs prevail on their APA challenge, this court must “set aside” CFTC’s ultra vires recission action, with nationwide effect. That affects persons in all judicial districts equally.
No. 24-50079 (March 1, 2024) (footnote omitted). As with last week’s decision in a similar posture involving SpaceX, it remains to be seen whether the transferee district court will return the case.
