# Acquittal
**The model:** The formal verdict that the prosecution failed to prove guilt beyond a reasonable doubt. An acquittal is not a finding of innocence — it is a finding that the state didn't carry its burden, and (via double jeopardy) it is *final*: the state gets one shot. The asymmetry is designed: convictions can be appealed; acquittals cannot.
## The Mechanism
Acquittal finality is a deliberate constraint on the state's most dangerous power — the power to retry forever until some jury convicts. It accepts false negatives (guilty people going free) as the price of blocking a worse failure mode: prosecution as attrition warfare. Jury nullification lives in the same protected space: because acquittals are unreviewable, juries hold an unappealable veto over enforcement, for good (fugitive-slave prosecutions) and ill (civil-rights-era murder acquittals).

### Impeachment acquittals and the impunity ratchet
Senate acquittals (2020, 2021) functioned less as verdicts than as precedents — each survived accountability attempt raised the demonstrated cost of the next attempt, the ratchet mechanism catalogued in [[Elite Impunity]]. The acquittal-as-vindication spin ("total exoneration") exploits the public's conflation of *not proven* with *innocent* — a burden-of-proof illiteracy worth naming every time. See [[Prima Facie]] for the underlying logic.
### Nullification politics
Organized appeals for jurors to acquit allies regardless of proof — visible at the edges of January 6 discourse — weaponize the unreviewable veto. The design tolerates it; the norm system has to answer it.
