Local votes and rules
⚖️ Court case
Several resident households appealed the land use approval for the PAX-1 data center. In September 2026 a judge refused to stop work while the case goes on, but also refused the developer's request to throw the case out.
✅ Approved
Middlesex Township's vote on final plans for the PAX-1 data center was postponed when too many people showed up for the meeting room, and was moved to August 19, 2026. Residents later took the township's land use approval to county court.
✅ Approved
Middlesex Township supervisors approved subdivision plans for PAX-1, an 18-building, 700-acre data center campus near Carlisle. Land development plans and power and water plans still needed approval.
🗺️ Zoning change
Middlesex Township created a Data Center Overlay District on farmland along Country Club Road at a landowner's request. This cleared the way for the large PAX-1 data center campus.
