This event represents severe constitutional damage through judicial validation of executive overreach against independent oversight. The firing of Inspectors General directly attacks institutional checks on executive power (separation:5, capture:5). The judicial refusal to halt this represents rule of law degradation (4) as courts fail to protect statutory independence of IGs. High corruption risk (4) as oversight removal enables unchecked executive action. Mechanism modifier 1.3 applies for judicial_legal_action that validates rather than checks executive overreach. Federal scope with moderate population yields 1.2 modifier. Severity multipliers: durability 1.2 (precedent for future IG removals), reversibility 0.9 (new IGs can be appointed but institutional damage persists), precedent 1.2 (establishes judicial deference to mass IG removal). A-score: 46.3. B-score moderate (20.9) due to technical legal nature limiting viral spread, though significant media coverage of oversight dismantling. Delta: +25.4 strongly indicates List A classification.
