Yesterday evening Mexico's Chamber of Deputies, the lower house of Congress, approved a transparency law requiring institutions receiving public funding to disclose how such resources were used. This would include political parties and labor unions. The law also stipulates that information on serious human rights violations cannot be withheld, although data that could harm the country's security or financial institutions can be kept from the public. The National Transparency System will be created to oversee the release of such information. Critics question whether the political will exists to ensure transparency and note that public officials will not be required to disclose their financial situation.
