MEXICO CITY, (Reuters) - Mexico’s Supreme Court temporarily suspended on Friday parts of a controversial electoral reform pushed by the country’s president, while also confirming it will consider a lawsuit from independent electoral institute INE that seeks to overturn it.

The congressional electoral reform passed by allies of President Andres Manuel Lopez Obrador last month was a scaled-down version of a failed constitutional reform he originally sought, but it still managed to slash the institute’s budget and headcount ahead of presidential elections next year.

The court stressed in a statement that it has frozen the articles of the reform challenged by INE.

“The case before us involves the possible violation of citizen’s political-electoral rights,” according to the court statement, which noted the lawsuit also involves constitutional questions that must be settled.

Late last month, Mexico’s Senate gave its final approval to the electoral reform known locally as “Plan B,” which critics warn will undermine democracy since it significantly downsizes the INE while giving more power to local officials, many of whom are members of Lopez Obrador’s MORENA party.
