House prosecution panel members in the impeachment case involving Vice President Sara Duterte request the opening of a sealed box from the Bureau of Internal Revenue (BIR) that is said to contain Duterte’s tax documents. The request is made during the ongoing impeachment pretrial conference, with House public prosecutors explaining that the materials are needed for the proceedings. According to statements cited by multiple outlets, the prosecution panel seeks the box’s opening to allow an inventory of its contents and to facilitate the documents’ use as evidence. Prosecutors say the tax records may be relevant to allegations in the case, including claims related to Duterte’s alleged unexplained wealth. One report notes the move is a formal request by the House prosecution panel, while another specifies that public prosecutor Leila de Lima confirms the request and ties it to the stage of pretrial in which evidence handling and documentation can be addressed. The coverage focuses on the procedural step of opening and inventorying the sealed BIR materials, rather than on any determination of their contents or evidentiary weight.
