1. Penalties that maybe imposed (Article 21)
No felony shall be punishable by any penalty not prescribed by law prior to its commission.
Note: Article 21 simply announces the policy of the State as regards punishing crimes.
This provision prohibits the government from punishing any person for any felony with any penalty which has not been prescribed by the law.
Article 21 - Is not a penal provision. It neither defines a crime nor provides a punishment for one. It has simply announced the policy of the government with reference to punishment of alleged criminal acts.

No penalty prescribed by law prior to its commission.
Example:
A was charged with “fraud or infringement of literary rights or property,” because A allegedly reproduced and sold fraudulent copies of another’s literary work.
