  4. Neighboring landowners asked a district court to review the approval, arguing it was procedurally flawed because one council member should not have voted; the city defended the approval, and the landowner and the developer asked to join its defense. (BoiseDev, Feb. 10, 2026)

Conflicts and open questions

  • A guest opinion column estimated the campus's demand at 600 to 800 MW; that figure is not from a record or the developer and is not used.
  • The Supreme Court appeal's case number and status were not checked in court records.
