Determinations are classified by reversibility and impact: reversible acts use standard rules; partially reversible acts require heightened scrutiny; irreversible acts require supermajorities in both chambers plus mandatory independent review; emergency acts are time-bounded with mandatory ex post review.
The threshold model is the decision architecture of the Board Statute: determinations are classified by reversibility and impact, and quorum, voting rules and review triggers escalate accordingly.
It is the concrete mechanism that makes reversible-first enforceable. A determination that ignores its class is procedurally defective and is itself subject to review and remedy.
Reversible determinations use standard quorum and voting rules with rollback-ready remedies. Partially reversible determinations require heightened scrutiny, bounded pilots and an enhanced review cadence. Irreversible determinations require supermajorities in both chambers and mandatory independent review whose independence criteria, scope and outcome are docketed. Emergency determinations are narrow in scope, time-bounded and subject to mandatory ex post review. Quorum distinguishes normal from constrained participation such as recusal or suspension.
The model does not rank decisions by importance in the abstract; it ranks them by how hard they are to undo. A high-impact but reversible act remains in the lower tier.
