“Whenever any person, convicted in any court of this Commonwealth of any crime, shall be sentenced to imprisonment in either the Eastern or Western Penitentiary, the court, instead of pronouncing upon such convict a definite or fixed term of imprisonment, shall pronounce upon such convict a sentence of imprisonment for an indefinite term; stating in such sentence the minimum and maximum limits thereof; fixing as the minimum time of such imprisonment, the term now or hereafter prescribed as the minimum imprisonment for the punishment of such offense; but if there be no minimum time so prescribed, the court shall determine the same, but it shall not exceed one fourth of the maximum time, and the maximum limit shall be the maximum time now or hereafter prescribed as a penalty for such offense: Provided, however, That when a person shall have twice before been convicted, sentenced and imprisoned in a penitentiary for a term of not less than one year, for any crime committed in this State, or elsewhere within the limits of the United States, the court shall sentence said person to a maximum of thirty years: And provided further, That no person sentenced for an indeterminate term shall be entitled to any benefits under the act, entitled ‘An act providing for the commutation of sentences for good behavior of convicts in prisons, penitentiaries, workhouses, and county jails in this State, and regulations governing the same,’ approved the eleventh day of May, Anno Domini one thousand nine hundred and one.” This section has been amended to read: “Whenever any person, convicted in any court of this Commonwealth of any crime, shall be sentenced to imprisonment in any penitentiary of the State, the court, instead of pronouncing upon such convict a definite or fixed term of imprisonment, shall pronounce upon such convict a sentence of imprisonment for an indefinite term; stating in such sentence the minimum and maximum limits thereof; and the maximum limit shall never exceed the maximum time now or hereafter prescribed as a penalty for such offense: Provided, That no person sentenced for an indeterminate term shall be entitled to any benefits under the act, entitled ‘An act providing for the commutation of sentences for good behavior of convicts in prisons, penitentiaries, workhouses and county jails in this State, and regulations governing the same,’ approved the eleventh day of May, Anno Domini one thousand nine hundred and one.” It will be seen that this amendment puts it into the power of the _court_ to fix _any_ minimum below the maximum, instead of a minimum not exceeding one fourth of the maximum; that it permits the court to name a lower maximum than the one now prescribed by law for any given offense; and that it strikes out the thirty-year clause altogether.
