The extension was requested by the Attorney General's Office, which argued that more time was needed to gather input from stakeholders and ensure a comprehensive set of rules. The original deadline was set to expire on March 10th, but the STF has now extended it to March 20th.

The new regulations are intended to streamline the process of amending the Brazilian constitution, which has been criticized for being overly complex and time-consuming. The STF's decision is expected to facilitate the passage of important reforms, such as those related to tax, social security, and political financing.

The government and Congress are expected to work together to develop the new rules, which will then be submitted to the STF for approval. Once approved, the regulations will provide a clearer framework for the amendment process and help to ensure that changes to the constitution are made in a transparent and accountable manner.
