The extension was requested by the government and Congress, who argued that they needed more time to reach a consensus on the new rules. The STF's decision comes as Brazil faces a backlog of proposed amendments, with over 150 currently pending. The new guidelines are expected to streamline the amendment process and ensure that only the most essential changes are made to the constitution. The STF's decision has been welcomed by legal experts, who believe that it will help to protect the integrity of the constitution and ensure that it remains a stable foundation for Brazilian democracy.
