Some states have used civil commitment proceedings to remove habitual *** offenders from society for extended periods of time. The United States Supreme Court ruled in Kansas v. Hendricks (1997) that such laws do not violate the Constitution's double jeopardy or ex post facto clauses.
Minnesota's civil commitment law for habitual *** offenders is fairly typical. Under Minnesota law, a person classified as having a "***ual psychopathic personality" or denominated a "***ually dangerous person" may be committed indefinitely in a secure treatment facility. The commitment is intended to reduce the risk of future dangerous ***ual behavior. It is not meant to serve a punishment for past crimes. Civilly committed *** offenders may be held for an indeterminate amount of time. In other words, they may be held as long as warranted to successfully treat them and to satisfy public safety concerns.
According to Minnesota's law, a person with a ***ual psychopathic personality is one who:
  • Has engaged in a "habitual course" of misconduct in ***ual matters
  • Suffers from an "utter lack of power to control" ***ual impulses
  • As a result of this inability to control behavior is "dangerous to other persons"

A ***ually dangerous person is defined as someone who has "engaged in a course of harmful ***ual conduct." This conduct creates a "substantial likelihood" of serious physical or emotional harm to another. Moreover, the person must be diagnosed with a ***ual, personality or mental disorder, and found likely to engage in harmful ***ual conduct in the future.
A commitment hearing is held to determine whether civil commitment is warranted. This hearing is usually held shortly before a *** offender is to be released from prison. Commitment proceedings could also be commenced as part of a plea agreement. A petition may also be filed after a person has been released from prison on a conditional or supervised release. It is not necessary that a person have committed any further ***ual offenses after the release from imprisonment.
