Ecuador's Constitutional Court ruled on Wednesday the opposition-dominated National Assembly can take up the question of whether to impeach President Guillermo Lasso over allegations of crimes against state security and corruption. The ruling was only a first step. The congress still must follow a formal process that requires the presentation of evidence and arguments before legislators may vote on impeachment. The court, which is the interpreter and guarantor of Ecuador's constitution, gave the go-ahead for impeachment proceedings on a 6-3 vote by the justices.
