its maximum period, adding one year for each additional 10,000 pesos; but the total penalty which may be imposed shall not exceed twenty years. xxx Under Section 1 of Act 4103,xviii[18] the maximum term of the penalty is that which, in view of the attending circumstances, could be properly imposed under the Revised Penal Code, and the minimum should be within the range of the penalty next lower to that prescribed for the offense. The penalty next lower should be based on the penalty prescribed by the Revised Penal Code for the offense, without first considering any modifying circumstance attendant to the commission of the crime. The minimum of the indeterminate penalty is left to the sound discretion of the court, to fix from within the range of the penalty next lower without reference to the periods into which it might be subdivided. The modifying circumstances are considered only in the imposition of the maximum term of the indeterminate sentence.xix[19] In Criminal Case Nos. 93-129377, 93-129378, 93-129380-84, the amount involved in each case is P15,000.00. Since the penalty prescribed by law therefor is prision correccional maximum to prision mayor minimum, the penalty next lower thereto is prision correccional minimum to prision correccional medium. Thus, the minimum of the indeterminate sentence to be meted here should be two (2) years, eleven (11) months and ten (10) days. Explicit is the said Indeterminate Sentence Law, that the maximum of the penalty shall be that which, in view of the attending circumstances, could be properly imposed under the Revised Penal Code. Accordingly, the maximum of subject indeterminate sentence of six (6) years, eight (8) months and twenty (20) days of prision mayor. In Criminal Case Nos. 93-129376 and 93-129379, the amount involved in each case is P22,600.00. Since the penalty prescribed by law therefor is prision correccional maximum to prision mayor minimum, to be imposed in its maximum period, the penalty next lower in degree should be four (4) years and two (2) months of prision correccional, and the maximum penalty therefor should be seven (7) years and four (4) months of prision mayor, in each case.
