Constitution of 1917, written after the Mexican
Revolution. It addresses in detail some of the
fundamental causes of that Revolution. Article 123,
which defines the Federal Labor law, and Article 27,

Laws
|
Laws are based
directly on the Constitution; all Mexican laws
receive their authority from the Constitution. Some
Laws like the Labor law are defined in great detail
in the Constitution. Laws define and assign
authority and responsibility for enforcement.
Laws begin as
initiatives from State or Federal Diputados, or
Senators, or from the Executive branch.
They are approved
by Congress and signed by the President. Each law
designates which Secretary (cabinet branch) is
responsible for oversight. |
Regulations
|
Regulations define the
Laws, Regulations are created by the Secretaries,
the President's cabinet and detail the procedures,
processes, etc. for compliance. |
Standards
(Norma Oficial Mexicana, NOM's)
|
NOM's have the force
of law. Most laws have several, some many. They
detail the form, format, documentation that must be
maintained for laws and regulations; they also
detail fines and sanctions.
