Mexico’s ruling party Morena will gain control of the Supreme Court following the country’s first-ever judicial elections, which were marred by low voter turnout and allegations of a power grab.

The Morena party controls most of Mexico’s government. Its sway over the Supreme Court is set to increase after a judicial election that raised fears about democracy.

Nearly 90 percent of voters did not cast ballots on Sunday, one of the lowest turnouts in any federal election since Mexico became a democracy.
