All nine seats on Mexico’s Supreme Court were taken by people with links to the ruling party. A new disciplinary tribunal which is empowered to punish judges will probably have a similar hue. The electoral tribunal looks like it will tilt the same way.

Mexican voters are gearing up for the first-ever judicial elections Sunday after a contested reform last year ordered the elections, despite vocal objections from the legal sector. Critics warn it will make judges more vulnerable to corruption and organized crime.

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.
