PRIMEXX ENERGY § OPPORTUNITY FUND, LP and § PRIMEXX ENERGY § OPPORTUNITY FUND II, LP, § Plaintiffs, § § Cause No. 24-BC01B-0010 v. § PRIMEXX ENERGY § CORPORATION, et al., Defendants §
═══════════════════════════════════════ ORDER ═══════════════════════════════════════
Before the court are special appearances by Defendants Angelo
Acconcia filed on October 30, 2024, and Blackstone Inc. filed on February 14,
2025. The court considered those special appearances, the responses, the
pleadings, the material on file, and counsels’ arguments.
Based on the above, the court concludes that it lacks personal
jurisdiction over those defendants and grants their special appearances. Accordingly, the court dismisses plaintiffs’ claims against Angelo Acconcia
and Blackstone Inc. without prejudice.
So ORDERED.
