summary - Wagner and Sancho sued CERN, the US Department of Energy, NSF, and Fermilab in US federal court (Hawaii) on 2008-03-21, seeking an injunction to halt the LHC until further environmental/safety review, on grounds it could produce a planet-destroying micro black hole or strangelet and that the US had failed to file a NEPA environmental impact statement. Judge Helen Gillmor granted the federal defendants’ motion to dismiss on 2008-09-26, holding the plaintiffs had not established the court’s jurisdiction (insufficient US governmental funding/control over CERN’s LHC operations to trigger NEPA) — the case turned entirely on jurisdiction, not on any judicial assessment of the physics. An appeal was dismissed in 2010.
relevance_note - The legal/public register of “was the risk put to rest”: the only judicial test of the safety case, and notably one that never reached the merits of the physical risk claim itself — a limit on what “the courts examined this” can be taken to mean.
