The Venezuelan congress voted President Maduro powers to
legislate
by decree on economic matters.
This is in accord with the constitution, but that doesn't mean it is a
good idea. Price controls tend to cause shortages, and Venezuela
already has shortages. I feel no sympathy for store owners that
gouge, but preventing future gouging requires changing the system that
generates the gouging.
The corruption accusations against Asambleadora Aranguren are not
inherently implausible, but this still seems fishy. The alleged
corruption took place before she ran for election as a supporter of
Chavez. However, the accusations were made in September 2013, after
she had switched parties, and when her vote became inconvenient.
It is proper to take action against corrupt legislators, but it should
be done in an unbiased way, not selectively based on their politics.
