laws are based on the Constitution - when there is a
change in a Law, a Regulation or a NOM (official Mexican
standard) - the new cancels the old. A reformed law
cancels earlier versions - this is always stated in the
"Transitorios" or Transitional articles at the end of
the Law, Regulation, or NOM. The old law disappears. All
laws, Regulations and NOMs are published in the DOF
(Official Daily of the Federation) before they become

many give a future date that can be months or years when
the new legislation takes effect.

to adapt their programs and actions to be fully
compliant when the law, regulation or NOM takes effect.
example, when there is a new HEALTH AND SAFETY or
ENVIRONMENTAL STANDARD published - you are required to
adapt your program to be fully compliant on the date
