For the first time in its history, Mexico’s Supreme Court has chosen a woman to be its president.

With a majority vote from her colleagues on Mexico’s high court, Justice Norma Piña was chosen to serve as its head for the next four years. In her first address as the court’s president, she thanked the majority for breaking through what she said had seemed an impenetrable “glass ceiling.”

“We will work and strive every day for a more just and more equitable society, one without violence against women,” she said. “Let there be no doubt about that desire.”

Piña’s fellow justice Yasmin Esquivel had also sought the role, but her candidacy was rocked by serious accusations of having plagiarized her undergraduate thesis.
