When the culprit has to serve two or more penalties, he shall serve them simultaneously if the nature of the penalties will so permit otherwise, the following rules shall be observed: In the imposition of the penalties, the order of their respective severity shall be followed so that they may be executed successively or as nearly as may be possible, should a pardon have been granted as to the penalty or penalties first imposed, or should they have been served out.
For the purpose of applying the provisions of the next preceding paragraph the respective severity of the penalties shall be determined in accordance with the following scale:
2. Reclusion perpetua,
3. Reclusion temporal,
4. Prision mayor,
5. Prision correccional,
6. Arresto mayor,
7. Arresto menor,
9. Perpetual absolute disqualification,
10 Temporal absolute disqualification.
11. Suspension from public office, the right to vote and be voted for, the right to follow a profession or calling, and
12. Public censure.
Notwithstanding the provisions of the rule next preceding, the maximum duration of the convict’s sentence shall not be more than three-fold the length of time corresponding to the most severe of the penalties imposed upon him.
No other penalty to which he may be liable shall be inflicted after the sum total of those imposed equals the same maximum period. Such maximum period shall in no case exceed forty years.
In applying the provisions of this rule the duration of perpetual penalties (pena perpetua) shall be computed at thirty years. (As amended).
