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.
