The maximum penalty for a disorderly persons offense is 6 months in jail, but that penalty is usually unlikely. Harassment is often improperly charged, and difficult for the state to prove, since it is the only offense cognizable in municipal court where the State has to prove the highest mens rea (criminal intent) standard or purpose to harass. Courts have held, for example, that cursing out a 911 dispatcher is not harassment since the purpose was not to harass. If the matter is in the shore area (Ocean or Monmouth Counties), feel free to call my office at 732-793-8808.
