Opposition lawmakers in Brazil are maneuvering to extend the activities of the Parliamentary Commission of Inquiry (CPMI) related to the National Social Security Institute (INSS), aiming to pressure Senate President Davi Alcolumbre. The opposition's main strategy revolves around using historical precedents where similar commissions were extended during Senate sessions rather than requiring a full Congressional session. This comes as Alcolumbre has indicated to his allies that he is against extending the CPMI’s work, citing the need for a meeting of the National Congress to endorse any extension.

The opposition has identified at least four instances where CPMIs have been successfully extended during Senate sessions. They highlight such past CPMIs as the one related to Fake News in 2020, the one involving Petrobras in 2014, and the inquiries into Violence against Women in 2013, which were all extended without requiring a full session of Congress. These historical instances are being cited to argue that only a Senate or House session should suffice for the continuation of the CPMI investigations into the INSS, challenging the current stance of Senate President Alcolumbre.

The CPMI of the INSS is set to conclude its work by March 28, and the opposition's actions indicate a strategic approach not just to extend the inquiry but also to assert their influence and highlight potential governmental overreach within legislative procedures. This situation reflects the ongoing political tensions in Brazil and the complexities of legislative processes, particularly in a climate where opposition parties are seeking to gain leverage against the ruling government.
