Which decree reorganized the Executive Branch and affected the Tariff Commission?

• A. Presidential Decree No. 1
• B. Presidential Decree No. 34, s. 1972
• C. Republic Act No. 1937
• D. Tariff Act of 1909

Answer: (A)

Presidential Decree No. 1 is the instrument that reorganized the executive branch, centralizing authority and reshaping how agencies fit into the new administrative structure. When a broad reorganization of the executive could be implemented by decree, it automatically affects agencies under that branch, including the Tariff Commission, by changing their placement, reporting lines, and potentially their functions within the new framework. The other options refer to separate pieces of legislation or older laws that don’t enact the same wide reorganization of the executive and its agencies, so they wouldn’t be the decree responsible for reorganizing the entire Executive Branch and impacting the Tariff Commission.
