Canon 1412

1. One who is bound by the law or a precept is also subject to

the penalty attached to it. 2. If the law is changed after the

offense was committed, the law more favorable to the accused is

to be applied. 3. If the subsequent law abolishes the law or

at least the penalty, it ceases at once irrespective of the manner in which it had been imposed. 4. The penalty binds the

guilty party everywhere even after the authority of the one who

has imposed the penalty has lapsed, unless it is expressly provided otherwise in common law.
