The CENAM belongs to the Economic Secretary.  My understanding is that this is the official department that would set the policy - similar to NIST in the US.

There were conflicting reports about this back when Mexico was
considering doing the change in October of this year.  As I understand
it, Mexico decided to move the change up to this month, and to stay on
EST all year.  For a brief summary please see:


It could well be that this is wrong.  There's at least one
English-language source saying that it hasn't been decided whether
Quintana Roo will observe DST:


and perhaps we'll need a further update once this becomes decided or
sufficiently clear.  That being said, my (admittedly limited)
understanding of QRoo politics suggests that they won't observe DST this
year.  That CENAM web page is reasonably generic and perhaps its author
didn't think about (or want to think about) predicting exactly what will
happen in April.
