The law on the subject, although frequently amended, is still based upon the Superannuation Act of 1859, which grants to "persons who shall have served in an established capacity in the permanent civil service of the state" for ten years, and retire at sixty years of age or by reason of infirmity, a pension equal to ten sixtieths of their final salary.

For every additional year of service another sixtieth is added up to a maximum of forty sixtieths.
