Under the leadership of President Hugo Chávez and now President Nicolás Maduro, the accumulation of power in the executive branch and erosion of human rights guarantees have enabled the government to intimidate, censor, and prosecute its critics, leading to increasing levels of self-censorship.
Leading opposition politicians were arbitrarily arrested, prosecuted, convicted, and barred from running for office in legislative elections scheduled to be held in December 2015. The government prosecuted dozens of lesser-known opponents for criticizing the government.
Police abuse, poor prison conditions, and impunity for abuses by security forces—including arbitrary arrests, beatings, and denial of basic due process rights for largely peaceful protesters in early 2014—remain serious problems.
Other concerns include lack of access to basic medicines and supplies—the result of problematic government policies—and continuous harassment of human rights defenders by government officials.
