Three strikes and habitual offender lawsMontana has two repeat-offender laws. A 'persistent felony offender' is someone being sentenced for a third felony who has two earlier felonies (each punishable by more than 1 year) and committed the new offense within 5 years of the last conviction or release; at least one of the three must be a sexual or violent offense.
