The Government Procurement Act (R.A. 9184) in the Philippines regulates procurement activities across all government branches, requiring transparency, competitiveness, and accountability. It mandates a structured approach to procurement, including the development of an annual procurement plan (APP) and the establishment of a Bids and Awards Committee (BAC) to oversee the procurement process. Violations can lead to significant penalties, including imprisonment for public officers and individuals involved in procurement offenses.
