A fine is a penalty that requires the convicted person to pay to the public treasure a sum of money fixed by law after an offense has been committed. The fine may be increased if the payment deadlines are not respected.
It is applicable in criminal (fairly rare), correctional (as a principal penalty along with imprisonment) and contraventional (as an exclusive principal penalty) matters.
Its amount varies according to the class of contravention. The fine may be suspended except for contraventions in the first four classes.
