Government Structure — Legislative, Executive & Judicial - Detailed Explanation
The Philippines follows a democratic system of government based on the principle of separation of powers. This means that the government is divided into three distinct branches: the Legislative (Congress), Executive (President and Cabinet), and Judicial (Courts). Each branch has specific roles and responsibilities, and they work together through a system of checks and balances to ensure good governance. Understanding this structure is crucial for the Civil Service Exam as it forms the foundation of Philippine government operations and public administration.
Concepts
Legislative Department (Congress)
The Legislative Department is the law-making branch of government, composed of two chambers: the Senate and the House of Representatives. This bicameral system ensures thorough deliberation of proposed laws. The Senate has 24 members elected nationally for 6-year terms (maximum of 2 consecutive terms), while the House of Representatives has a maximum of 250 members elected from districts and through the party-list system for 3-year terms (maximum of 3 consecutive terms). Congress holds the power to create, amend, and repeal laws that govern the country.
Examples
The minimum age for Representatives is 25 years (qualified), but for Senators it's 35 years (not yet qualified). The person meets all other requirements: natural-born citizen, able to read and write, and can be a registered voter.
Scenario
A 30-year-old Filipino lawyer wants to run for Congress
Solution
This person can only run for the House of Representatives, not the Senate
Under the party-list system, sectoral organizations like labor groups can have congressional representation if they receive at least 2% of total party-list votes, entitling them to one representative.

Solution
They can form a party-list and register with COMELEC

Executive Department (President and Cabinet)
The Executive Department is headed by the President, who serves as both the Head of State and Head of Government. The President is elected directly by the people for a single 6-year term with no possibility of reelection. The Executive branch is responsible for implementing and enforcing laws passed by Congress. The President appoints Cabinet secretaries, heads of bureaus, ambassadors, and other key officials. This branch also includes the Vice President, who serves the same term and may succeed the President if needed.
Examples
The President has the constitutional power to veto bills passed by Congress. However, Congress can override this veto with a two-thirds vote in both chambers, demonstrating the system of checks and balances.
Scenario
Congress passes a bill the President disagrees with
Solution
The President can exercise veto power to reject the bill
The President has direct authority over all military forces and can deploy them for disaster relief, national defense, or maintaining peace and order, subject to legal and constitutional limitations.

Judicial Department (Court System)
The Judicial Department is the branch responsible for interpreting laws and ensuring justice. It is headed by the Supreme Court, which has one Chief Justice and 14 Associate Justices. The court system is hierarchical, starting from Municipal/Metropolitan Trial Courts at the local level, progressing through Regional Trial Courts, the Court of Appeals, and finally the Supreme Court. Special courts like the Sandiganbayan and Court of Tax Appeals handle specific types of cases. The judiciary has the power of judicial review, allowing it to determine the constitutionality of laws and government actions.
Examples
Through the power of judicial review, the Supreme Court can examine laws passed by Congress and executive actions to ensure they comply with the Constitution. If found unconstitutional, the law becomes null and void.
Scenario
A law passed by Congress is challenged as unconstitutional
Solution
The Supreme Court can exercise judicial review to determine constitutionality
The Sandiganbayan is a special court created specifically to handle corruption cases involving government officials and employees. This ensures specialized handling of such cases with judges experienced in anti-graft laws.
Scenario
A government official is accused of graft and corruption

Constitutional Commissions
The 1987 Constitution established three independent Constitutional Commissions to ensure important government functions remain free from political interference: the Civil Service Commission (CSC), Commission on Elections (COMELEC), and Commission on Audit (COA). Each commission is composed of a Chairman and Commissioners with 7-year terms without reappointment. These commissions have constitutional independence and specific mandates that are crucial to democratic governance and public administration.
Examples
The CSC is responsible for ensuring merit-based appointments and promotions in government service. They investigate violations of civil service laws and can impose appropriate sanctions.
Scenario
A government employee files a complaint about unfair promotion practices
Solution
The Civil Service Commission would investigate and resolve the matter
COA has the constitutional mandate to examine all government expenditures and can disallow irregular, unnecessary, excessive, or unconscionable spending. They report findings and recommend corrective actions.

Local Government Structure
The Philippines has a decentralized system of local governance consisting of several levels: Regions, Provinces, Cities, Municipalities, and Barangays. This structure, implemented through the Local Government Code of 1991 (RA 7160), provides for local autonomy while maintaining national unity. Each level has specific functions and elected officials. Cities are classified as Highly Urbanized, Independent Component, or Component Cities based on population and income criteria. The barangay is the smallest political unit and the foundation of Philippine local governance.
Examples
To become a Highly Urbanized City, a locality needs at least 200,000 population and P100 million annual income. Component cities have lower requirements and remain under provincial supervision.
Scenario
A municipality wants to become a city
Solution
It must meet specific population and income requirements set by law
As the basic unit of government, barangays handle local issues through their elected officials. More complex matters may be elevated to municipal or city level.

A barangay issue needs to be resolved
Solution
The Punong Barangay (Barangay Chairman) and Sangguniang Barangay handle local matters

When both chambers pass identical versions of a bill, it goes to the President who has several options: sign it into law, veto it and return to Congress with objections, or allow it to become law without signature after 30 days (if Congress is in session).
Problem
A bill has been passed by both chambers of Congress with identical provisions. What happens next in the legislative process?
Solution
The bill is sent to the President for signature or veto.
The Supreme Court's power of judicial review is final regarding constitutional interpretation. Congress's options are limited to: crafting new legislation that complies with the Constitution, or initiating the constitutional amendment process to change the constitutional provision in question.
Problem
The Supreme Court declares a law passed by Congress as unconstitutional. Can Congress do anything about this decision?
Solution
Congress cannot directly overturn the Supreme Court's constitutional interpretation, but they can pass a new law that addresses the constitutional issues or propose a constitutional amendment.
