Venezuela’s Supreme Court says it will take legislative power away from Congress, ruling late Wednesday that opposition lawmakers are in contempt of court for swearing in three lawmakers banned over charges of voter fraud. The ruling consolidated President Nicolas Maduro’s grip on power and drew outrage from opposition lawmakers. In Caracas, the president of the National Assembly, Julio Borges, tore up a copy of the Supreme Court’s order, calling it “trash.”

Julio Borges: “It is a coup in every possible way. It is a dictatorship, and the entire world needs to help Venezuela right now sound the alarm in every democratic nation of the world.”

Opposition parties are planning mass street demonstrations across Venezuela this weekend to protest the court’s ruling. The head of the Organization of American States called the ruling a “self-inflicted coup.” The ruling comes as Venezuela grapples with high inflation and a deep recession, which has led to shortages of food, medicine and other necessary goods.
