History: 1971 act removed requirements that offenders under Subsecs. (a) and (b) have been previously convicted and imprisoned “two or more times” and “at separate times” and redefined persistent larceny offender as one who stands convicted of larceny in “the third or fourth degree” rather than in “the second or a lesser degree” in Subsec.

(c) to reflect the establishment of six degrees of larceny pursuant to P.A. 82-271 by including persons convicted of larceny in the third degree “in violation of the provisions of section 53a-124 in effect prior to October 1, 1982” and larceny in the “fifth or sixth” degree; P.A. 85-603 made a technical change to Subsec.

(a), (b) and (d); P.A. 94-37 amended Subsec. (f) to revise the penalty for a person found to be a persistent dangerous felony offender by replacing the provision that permitted the court to impose the sentence of imprisonment authorized for a class A felony with the provision requiring the court to sentence such person to a term of imprisonment of not more than 40 years and by adding the provision requiring the court to sentence such person to a term of imprisonment of not more than life if such person has been twice convicted and imprisoned for any of the crimes enumerated in Subsec.

Finding by trial court, rather than jury, that imposing extended incarceration would best serve the public interest clearly violated defendant's constitutional rights under the sixth amendment to U.S. Constitution; section is unconstitutional to the extent it does not provide that defendant is entitled to have jury make a required finding that exposes defendant to a greater punishment than that authorized by jury's guilty verdict. 283 C. 748.

(a) and of his conviction of attempt to escape from custody under Subsec. (b) and defendant's arguments that his conviction of robbery in the first degree under Subsec. (a) precludes a sentence enhancement under Subsec. (b) and that the legislature did not intend for more than one recidivist enhancement to apply to the conviction of multiple current charges because he was not afforded the opportunity to reform are without merit. 173 CA 119.

Purpose is to allow sentencing court to impose a more severe sentence than would be allowed for the substantive offense; Subsec. requires sentencing court to consider defendant's history and character and the nature and circumstances of his criminal conduct and whether extended incarceration and lifetime supervision will best serve the public interest; there is no requirement that sentences imposed be strictly proportional to the nature of substantive offense or offenses of which defendant was convicted; nature of substantive offense is only one factor to be considered by sentencing court. 254 C. 613.
