These variables are employed first to analyze the decision of the court to refer defendants for presentence investigation when such a referral is not mandatory, then to examine how these referrals, once made, influence disposition. The relationship of legal representation to disposition is also explored. The findings contradict conventional wisdom regarding the advantages to defendants of legal representation and of presentence reports. Lawyers do not appear to influence either referral or sentencing. The presentence reports are requested by judges seeking to individualize their sentencing decisions, but this process of individualization is as likely to result in harsher sentences as in greater leniency.
