New/Unique in this Election:

On 2 March 2023, Congress approved a set of reforms to laws on elections, political parties, judicial powers, and electoral crimes. These reforms would have cut the budget  and staff of the National Electoral Institute (INE) and relaxed restrictions on partisan speech and activities by public officials. However, the Supreme Court struck down part of these reforms on 8 May 2023 and struck the remainder on 22 June 2023 on the basis that Congress had violated the constitutional principle of democratic deliberation in their haste to pass the reforms. The Court also reinstated prior electoral laws.
