A ruling this week by Venezuela’s Supreme Court stripping the nation’s legislative branch of all authority — and vesting that power in the court itself — moves a country already beset by violence and economic scarcity one step closer to outright dictatorship.  The decision means essentially that every arm of Venezuela’s government is now under the thumb of President Nicolás Maduro, whose supporters have gone to great lengths to wrest authority from the National Assembly, which has been dominated by a slate of opposition parties since early 2016. The country’s top court, which is packed with Maduro loyalists, had already invalidated every major law passed by Congress. On Wednesday, as part of a decision involving the executive branch’s authority over oil ventures, the court declared that henceforth the judicial branch would execute all powers normally reserved for the legislature.

The ruling provoked international condemnation and sent shock waves across the region. It also prompted a strikingly public rebuke from Luisa Ortega, a Maduro loyalist who serves as the nation’s chief prosecutor. She denounced the decision in a televised address during which she brandished a copy of Venezuela’s Constitution.  The court’s ruling represents a “rupture in the constitutional order,” Ms. Ortega said, speaking at the Public Ministry, which she leads. “We call for reflection so that democratic norms are followed,” she added, eliciting hearty applause from colleagues who appeared stunned by the gravity of the moment.
