How New Hampshire classifies criminal offenses §651:2

New Hampshire divides criminal offenses into felonies and misdemeanors. The classification determines the maximum and minimum penalties a court may impose.

Felony classifications

  • Class A felony: 0–15 years, up to $4,000 fine - Class B felony: 0–7 years, up to $4,000 fine

Misdemeanor classifications §651:2

  • Class A misdemeanor: up to 12 months, $2,000 fine - Class B misdemeanor: up to 0 months, $1,200 fine
✓The classification of an offense determines not just the potential jail or prison time, but also fines §651:2 et seq., Probation length, and long-term consequences like employment restrictions and loss of civil rights.

The criminal process: arrest through resolution

1
Arrest
Law enforcement may arrest with or without a warrant §594:10. Officers may arrest without a warrant for felonies on probable cause and for misdemeanors committed in their presence. NH RSA § 594:10 governs warrantless arrest authority. You have the right to remain silent and the right to an attorney from this point forward.
2
Bail and pretrial release
New Hampshire Constitution Part I, Art. 32 guarantees bail for all except capital offenses when proof is evident. Courts set bail using risk assessment tools and statutory criteria. Pretrial detention without bail available for high-risk defendants under RSA 597:2. §597:1 et seq.
3
Arraignment
The court formally presents charges, and the defendant enters a plea. Nolo contendere (no contest) pleas are permitted.
4
Pretrial motions
The defense may file motions to suppress evidence, dismiss charges, or challenge procedures. This stage can determine the outcome of the case.
5
Trial or plea
Most criminal cases resolve through plea negotiations. If the case goes to trial, the state must prove guilt beyond a reasonable doubt to a 12-member jury that must reach a unanimous verdict.
6
Sentencing
If convicted, the judge imposes a sentence within the statutory range for the offense classification. Sentencing may include incarceration, Probation §651:2, fines, Restitution, and community service.

Your rights in a criminal case

Every person accused of a crime in New Hampshire has constitutional protections:

  • Right to remain silent — You cannot be compelled to testify against yourself §U.S. Const. amend. V
  • Right to an attorney — If you cannot afford one, one will be appointed §604-A:1 et seq.. New Hampshire Public Defender (NHPD) is a nonprofit contract agency providing statewide indigent defense under contract with the state. Covers trial and appellate work.
  • Right to a speedy trial — New Hampshire does not set a fixed number of days for speedy trial. New Hampshire has no fixed statutory speedy trial day limit. Constitutional Barker v. Wingo balancing test applies. NH courts consider length of delay, reason, assertion of right, and prejudice. Remedy is dismissal with prejudice.
  • Presumption of innocence — The prosecution bears the entire burden of proof. You do not have to prove anything.
  • Right to confront witnesses — You may cross-examine every witness the state calls against you
