This paper is a review of Maryland's Defective Delinquency
Law, which identifies a group of chronic criminals who are
dangerous to society and provides for their treatment along with,
perhaps, their indeterminate detention in Patuxent Institution.
Several sections of the law have come under legal attack; among
them, the indeterminate sentence provision has been most se
verely and most frequently attacked, although it is, from the
therapist's point of view, the single most effective tool in the
treatment of these men. In recent decisions, all the way up to
the United States Court of Appeals, the law has been held to be
constitutional, and treatment practices under it have led to one
of the lowest recidivism rates in the United States.
