The Senate Committee on Health and Public Welfare conducted an investigation in aid of legislation to examine reported irregularities in the government's procurement of COVID-19 vaccines. Dr. Rodrigo Lim, the Chief Executive Officer of PhilHealth, was invited as a resource person. At the hearing, the Senate Committee asked Dr. Lim to identify the government officials who approved the allegedly overpriced vaccine contracts and to explain the approval process. Dr. Lim invoked his right against self-incrimination and refused to answer, asserting that his responses might expose him to criminal prosecution for graft and plunder. The Committee immediately cited Dr. Lim in contempt and ordered his indefinite detention until he answered the questions. Is the contempt order valid? (Bar 2026 Syllabus)
