The Brazilian Supreme Court’s Chief Justice Luiz Fux on Wednesday issued a sharp rebuttal to President Jair Bolsonaro, one day after the right-wing leader escalated his feud with the court by vowing to no longer abide by one of its justice’s rulings.

“Encouraging non-compliance with court decisions is undemocratic, illicit and intolerable,” Fux said in a nationally televised message. He added that if Bolsonaro were to disobey a court ruling, or someone else were to do so at his urging, it would constitute a crime.
