The Senate impeachment court has authorized subpoenas for bank and tax records of Vice President Sara Duterte and her husband, lawyer Manases Carpio.Former congressman Oscar Moreno, who prosecuted former president Joseph Estrada, emphasized that financial documents are crucial in tracing the sources and movements of funds linked to Duterte's alleged unexplained wealth.Moreno argued that bank confidentiality should not shield corruption, calling for transparency and accountability in public office.He highlighted how records can reveal transactions, including cash payments, and noted that such data could expose hidden assets.The defense claims the subpoenas are illegal, but Moreno stressed that lawful court orders justify access to financial information.The case draws parallels to Estrada's impeachment, where a bank account was central to corruption allegations.Moreno also mentioned the role of Anti-Money Laundering Council reports in identifying suspicious transactions.The debate underscores tensions between financial privacy and public accountability in high-profile legal cases.
