The Philippines is an archipelago of 7,107 islands with a land area of 299,740 sq. kilometers. It is surrounded by the Pacific Ocean on the East, South China Sea on the North and the West and the Celebes Sea on the South. This comprises the National Territory of the Philippines. Article I of the 1987 Constitution provides that the "national territory comprises the Philippine archipelago, with all the islands and waters embraced therein and all other territories which the Philippines has sovereignty or jurisdiction."

The Filipino culture was molded over more than a hundred ethnic groups consisting of 91% Christian Malay, 4% Muslim Malay, 1.5% Chinese and 3% others. As of the 2000 national census, the population of the Philippines is 76.8 million and is now estimated at 88,706,300 million. The census is scheduled to be undertaken this 2007.

Filipino is the national language (1987 Constitution, Art. XIV, sec. 6). However, Filipino and English are the official languages for the purpose of communication and instruction (Art. XIV, sec 7). There are several dialects or regional languages spoken throughout the different islands of the country, but there are eight major dialects, which include Bicolano, Cebuano, Hiligaynon or Ilongo, Ilocano, Pampango, Pangasinense, Tagalog, and Waray.

There are two major religions of the country: Christianity and Islam. Christianity, more particularly Catholicism, is practiced by more than 80% of the population. It was introduced by Spain in 1521. The Protestant religion was introduced by American missionaries.

Aglipay, or the Philippine Independent Church, and the Iglesia ni Kristo are two Filipino independent churches. Other Christian religious organizations like the El Shaddai and 'Jesus is Lord' have been established and have a great influence to the nation.

Religion has a great influence in the legal system of the Philippines. For the Muslim or Islamic religion, a special law, the Code of Muslim Personal Laws, was promulgated and special courts were established, the Shari'a courts.

2. Political Structure

The Constitution is the fundamental law of the land. The present political structure of the Philippines was defined by the 1987 Constitution, duly ratified in a plebiscite held on February 2, 1987.

The 1987 Constitution provides that the Philippines is a democratic and republican state where sovereignty resides in the people and all government authority emanates from them (Article II, section 1).

3. Government Structure

The government structure differs as one goes through the history of the Philippines, which may be categorized as follows: a) Pre-Spanish; b). Spanish period; c). American period; d). Japanese period; e). Republic; and f). Martial Law Period

a) Pre-Spanish (before 1521)

The Barangays or independent communities were the unit of government structures before Spain colonized the Philippines. The head of each barangay was the Datu. He governs the barangays using native rules which are customary and unwritten. There were two codes during this period: the Maragtas Code issued by Datu Sumakwel of Panay Island and the Code of Kalantiao issued by Datu Kalantiano in 1433. The existence of these codes is questioned by some historians.

Just like many ancient societies, trial by ordeal was practiced.

b) Spanish period (1521-1898)

The Spanish period can be traced from the time Magellan discovered the Philippines when he landed on Mactan Island (Cebu) on March 16, 1521. Royal decrees, Spanish laws, and/or special issuances of special laws for the Philippines were extended to the Philippines from Spain by the Spanish Crown through the councils. The chief legislator is the governor-general who exercises legislative functions by promulgating executive decrees, edicts or ordinances with the force of law. The Royal Audencia, or Spanish Supreme Court, in the Philippines also exercised legislative functions when laws are passed in the form of autos accordados. Melquiades Gamboa, in his book entitled " An Introduction to Philippine Law" (7th ed, 1969), listed the most prominent laws in this period: Fuero Juzgo, Fuero Real, Las Siete Partidas, Leyes de Toros, Nueva Recopilacion de las Leyes de Indias and the Novisima Recopilacion. Some of these laws were also in force in other Spanish colonies. Laws in force at the end of the Spanish rule in 1898 are as follows: Codigo Penal de 1870, Ley Provisional para la Aplicaciones de las Dispociciones del Codigo Penal en las Islas Filipinas, Ley de Enjuciamento Criminal, Ley de Enjuciameniento Civil, Codigo de Comercio, Codigo Civil de 1889, Ley Hipotecaria, Ley de Minas, Ley Notarial de 1862, Railway Law of 1877, Law of Foreigners for Ultramarine Provinces and the Code of Military Justice. Some of these laws remained in force even during the early American period and/or until Philippine laws were promulgated.

In between the Spanish and the American period is what Philippine historians consider the first Philippine Republic. This was when General Emilio Aguinaldo proclaimed the Philippine Independence in Kawit , Cavite on June 12, 1898. The Malolos Congress also known as Assembly of the Representatives, which can be considered as revolutionary in nature, was convened on September 15, 1898. The first Philippine Constitution, the Malolos Constitution was approved on January 20, 1899. General Emilio Aguinaldo was the President and Don Gracio Gonzaga as the Chief Justice. A Republic, although with de facto authority, was in force until the start of the American Sovereignty when the Treaty of Paris was signed on December 10, 1898.

c) American period (1898-1946)

The start of this period can be traced after the Battle of Manila Bay when Spain ceded the Philippines to the United States upon the signing of the Treaty of Paris on December 10, 1898. A military government was organized with the military governor as the chief executive exercising executive, legislative and judicial functions. Legislative function was transferred to the Philippine Commission in 1901 which was created by the United States President as commander-in-chief of the Armed forces and later ratified by the Philippine Bill of 1902. This same Bill provided for the establishment of the First Philippine Assembly which convened on October 16, 1907. The Jones law provided for the establishment of a bicameral legislative body on October 16, 1916, composed of the Senate and the House of Representatives.

The United States Constitution was recognized until the promulgation of the Philippine Constitution on February 8, 1935, signed by U.S. President Franklin Delano Roosevelt on March 23, 1935 and ratified at a plebiscite held on May 14, 1935.

The organic laws that governed the Philippines during this period were: President McKinley's Instruction to the Second Philippine Commission on April 7, 1900; Spooner Amendment of 1901; Philippine Bill of 1902; Jones Law of 1916 and the Tydings McDuffie Law of May 1, 1934. The later law is significant for it allowed the establishment of a Commonwealth government and the right to promulgate its own Constitution. The 1935 Constitution initially changed the legislative system to a unicameral system. However, the bicameral system was restored pursuant to the 1940 Constitutional amendment. The Commonwealth government is considered as a transition government for ten years before the granting of the Philippine independence. Cayetano Arellano was installed as the first Chief Justice in 1901. The Majority of the Justices of the Philippine Supreme Court were Americans. Decisions rendered by the Supreme Court of the Philippines were appealed to the United States Supreme Court, which were reported in the United States Supreme Court Reports.

Manuel L. Quezon and Sergio Osmeña were elected as President and Vice-President respectively during the September 14, 1935 elections. In this election, President Quezon won over General Emilio Aguinaldo and Bishop Gregorio Aglipay, the President of the First Philippine Republic (1898) and the head of the Aglipayan church, respectively. This Commonwealth government went into exile in Washington DC during the Japanese period from May 13, 1942 to October 3, 1944. President Manuel L. Quezon died on August 1, 1944 and was succeeded by President Sergio Osmena who brought back the government to Manila on February 28, 1945.

d) Japanese period (1941-1944)

The invasion of the Japanese forces when Clark Field, an American military airbase in Pampanga, was bombed on December 8, 1941, marked the start of the Japanese period which lasted for three years. A Japanese Republic was established with Jose P. Laurel as its President. Jose Yulo was the Chief Justice of the Supreme Court. This period was considered as a military rule by the Japanese Imperial Army. The 1943 Constitution was ratified by a special national convention of the Kapisanan sa Paglilingkod ng Bagong Pilipinas (KALIBAPI). This period lasted for three years and ended in 1944 with the defeat of the Japanese forces.

e) Republic period (1946-1972)

July 4, 1946 was the inauguration of Philippine independence. A Philippine Republic was born. A republic means a government by the people and sovereignty resides in the entire people as a body politic. The provisions of the 1935 Constitution defined the government structure which provided for the establishment of three co-equal branches of government. Executive power rests in the President, legislative power in two Houses of Congress and judicial power in the Supreme Court, and inferior courts. Separation of powers is recognized.

Efforts to amend the 1935 Constitution started on August 24, 1970 with the approval of Republic Act No. 6132 where 310 delegates were elected on November 10, 1970. On June 1, 1971, the Constitutional Convention met. While it was still in session, President Ferdinand E. Marcos declared Martial Law on September 21, 1972. The Constitutional Convention completed the draft Constitution on November 29, 1972. It was submitted for ratification through citizens' assemblies on January 17, 1973. This is known as the 1973 Constitution.

f) Martial Law Period (1972-1986).

The Congress of the Philippines was abolished when Martial Law was declared on September 21, 1972. The Martial Law period was governed by the 1973 Constitution which established a parliamentary form of government. Executive and legislative powers were merged and the Chief Executive was the Prime Minister who was elected by majority of all members of the National Assembly (Parliament). The Prime Minister had the power to advise the President. The President is the symbolic head of state. This parliamentary government was never implemented due to the transitory provision of the 1973 Constitution. Military tribunals were also established. Amendments to the Constitution were made wherein by virtue of amendment No. 3, the powers of the President and the Prime Minister were merged into the incumbent President Ferdinand E. Marcos. Amendment No. 6 authorized President Marcos to continue exercising legislative powers until Martial law is in effect. Amendment No. 7 provided for the barangays as the smallest political subdivision and the sanggunians, or councils. The 1981 amendment introduced the modified presidential/parliamentary system of government of the Philippines. The President shall be elected by the people for a term of six years while the Prime Minister shall be elected by a majority of the Batasang Pambansa (Parliament) upon the nomination of the President. He was the head of the Cabinet and had supervision over all the ministries.

Proclamation No. 2045 (1981) lifted Martial Law and abolished military tribunals. Elections were held on June 16, 1981 and President Marcos was re-elected into office as President. The constitution was again amended in 1984 and a plebiscite was held on January 27, 1984 pursuant to Batas Pambansa Blg. 643 (1984). Elections were held on May 14, 1984 for the 183 elective seats in the 200 member of the Batasang Pambansa.

An impeachment resolution by 57 members of the opposition was filed against President Marcos but was dismissed. A special presidential election, popularly known as Snap Election, was called by President Marcos on November 3, 1985 and was held on February 7, 1986. The National Movement for Free Elections, or NAMFREL, results showed that Corazon Aquino led by over a million votes. However, the Batasang Pambansa declared that Ferdinand E. Marcos and Arturo M. Tolentino won over Corazon C. Aquino and Salvador H. Laurel as President and Vice-President, respectively. This event led to the People Power revolution, which ousted President Marcos on February 25, 1986.

g) Republic Revival (1986-present)

The Republic period was revived after the bloodless revolution popularly known as People Power or the EDSA Revolution.

Corazon C. Aquino and Salvador H. Laurel took their oath of office as President and Vice President of the Philippine Republic on February 25, 1986. Proclamation No. 1 (1986) was promulgated wherein the President and the Vice President took power in the name and by the will of the Filipino people. Proclamation No. 3 (1986) adopted as the Provisional Constitution or Freedom Constitution, provided for a new government.

A Constitutional Commission was constituted by virtue of Article V of the Provisional Constitution and Proclamation No. 9 (1986). The Constitutional Commission, composed of 48 members, was mandated to draft a Constitution. After 133 days, the draft constitution was submitted to the President on October 15, 1986 and ratified by the people in a plebiscite held on February 2, 1987. Under the transitory provision of the 1987 Constitution, the President and Vice President elected in the February 7, 1986 elections were given a six year term of office until June 30, 1992. Congressional elections were held on May 11, 1987. The Republican form of government was officially revived when the 1987 Constitution was ratified and Congress was convened in 1987. Legislative enactments again rested in the Congress. Republic Acts were again issued by Congress, the number of which took off from the last number used before Martial Law was declared. The numbering of Republic Acts continued from the number last used before Martial Law (Republic Act No. 6635 (1972) and Republic Act No. 6636 (1987). The Republic form of government by virtue of the 1987 Constitution was the same type of republican government prior to Martial law by virtue of the 1935 Constitution with three co-equal branches: Executive, Legislative and the Judiciary.

The Philippines once again became a Republic by virtue of the 1987 Constitution. The same type of republican form of government prior to Martial law was established with three co-equal branches were organized, Executive, Legislative and the Judiciary.

3.1 Executive Branch

The President is vested with the executive power. (Art. VII, sec. 1, 1987 Constitution). The President is both the Chief of State (head of government) and the Commander-in-Chief of all the Armed Forces of the Philippines (Art. VII, sec. 18). Since 1898 when the First Philippine Republic was established, the Philippines has had thirteen (13) Presidents.

The other members of the Executive Branch are the Vice-President and the Heads of Executive Departments or Cabinet members.

The following are the Departments under the Executive Branch:

There are specific bureaus and offices directly under the Office of the President.

Both the President and the Vice-President are elected by direct vote of the Filipino people for a term of six years. The President is not eligible for a reelection while the Vice President cannot serve for more than two terms. Congress is empowered to promulgate rules in the canvassing of certificates of election. The Supreme Court sitting en banc is the sole judge of all election contests relating to their election, returns and qualifications (Art VII, sec. 4). The Supreme Court en banc thus acts as the Presidential Electoral Tribunal. The Supreme Court promulgated the 2005 Rules on the Presidential Tribunal (A.M. No. 05-11-06-SC). Both may be removed from office by impeachment (Art. XI sec. 2) to be initiated by the House of Representatives (Art. XI, sec, 3) and tried and decided by the Senate (Art. XI, sec, 3 (6)). The Cabinet members are nominated by the President, subject to the confirmation of the Commission on Appointments (Art. VII, sec, 16) which consists of the President of the Senate, as ex- officio Chairman, twelve Senators and twelve members of the House of Representatives (Art. VI, sec. 1).

Cabinet members are nominated by the President, subject to the confirmation of the Commission on Appointments (Art. VII, sec, 16), which consists of the President of the Senate, as ex officio Chairman, twelve Senators and twelve members of the House of Representatives (Art. VI, sec. 1).

The President exercises control over all the executive departments, bureaus and offices (Art. VI, sec, 17).

3.2 Legislative Department

Legislative power is vested in the Congress of the Philippines, consisting of the Senate and the House of Representatives (Art. VI, sec. 1). History has provided that the legislative structure has undergone numerous changes. To better appreciate its transition, the Philippine Senate has provided a detailed account and is found on Senate website.

(Art. VI, sec. 17). The Senate Electoral Tribunal has approved on November 12, 2003 its Revised Rules.

House of Representatives

The House of Representatives is composed of not more than two hundred fifty (250) members, elected by legislative districts for a term of three years.

3.3 Judicial Department/System

Organizational Chart of the whole Judicial System and those of each type of Court is available in 2002 Revised Manual of Clerks of Court . Manila: Supreme Court, 2002. Amended by Republic Act No. 9282 (CTA)

Judicial power rests with the Supreme Court and the lower courts, as may be established by law (Art. VIII, sec. 1). The judiciary enjoys fiscal autonomy. Its appropriation may not be reduced by the legislature below the appropriated amount the previous year (Art. VIII, sec. 2). The Rules of Court of the Philippines as amended and the rules and regulations issued by the Supreme Court define the rules and procedures of the Judiciary. These rules and regulations are in the form of Administrative Matters, Administrative Orders, Circulars, Memorandum Circulars, Memorandum Orders and OCA Circulars. To inform the members of the Judiciary, legal profession and the public of these rules and regulations, the Supreme Court disseminates this rules and regulations to all courts, publishes important ones in newspapers of general circulation, prints in book or pamphlet form and now downloads them in the Supreme Court website and the Supreme Court E-Library website.

Department of Justice Administrative Order No. 162 dated August 1, 1946 provided for the Canon of Judicial Ethics. Supreme Court of the Philippines promulgated a new Code of Judicial Conduct for the Philippine Judiciary effective June 1, 2004 (A.M. No. 03-05-01-SC), which was published in two newspapers of general circulation on May 3, 2004 (Manila Bulletin & Philippine Star) and available on its website and the Supreme Court E-Library website.

The Supreme Court promulgated on June 21, 1988 the Code of Professional Responsibility for the legal profession. The draft was prepared by the Committee on Responsibility, Discipline and Disbarment of the Integrated Bar of the Philippines.

A Code of Conduct for Court Personnel (A.M. No. 03-06-13-SC) was adopted on April 13, 2004, effective June 1, 2004, published in two newspapers of general circulation on April 26, 2004 (Manila Bulletin & Philippine Star) and available at its website and the Supreme Court E-Library website.

Supreme Court of the Philippines

The barangay chiefs exercised judicial authority prior to the arrival of Spaniards in 1521. During the early years of the Spanish period, judicial powers were vested upon Miguel Lopez de Legaspi, the first governor general of the Philippines where he administered civil and criminal justice under the Royal Order of August 14, 1569.

The Royal Audencia was established on May 5, 1583, composed of a president, four oidores (justices) and a fiscal. The Audencia exercised both administrative and judicial functions. Its functions and structure were modified in 1815 when its president was replaced by a chief justice and the number of justices was increased. It came to be known as the Audencia Territorial de Manila with two branches, civil and criminal. Royal Decree issued July 24, 1861 converted it to a purely judicial body wherein its decisions were appealable to the Supreme Court of the Philippines to the Court of Spain in Madrid. A territorial Audencia in Cebu and Audencia for criminal cases in Vigan were organized on February 26, 1898. The Audencias were suspended by General Wesley Merrit when a military government was established after Manila fell to American forces in 1898. Major General Elwell S. Otis re-established the Audencia on May 29, 1899 by virtue of General Order No. 20. Said Order provided for six Filipino members of the Audencia. Act No. 136 abolished the Audencia and established the present Supreme Court on June 11, 1901 with Cayetano Arellano as the first Chief Justice together with associate justices, the majority of whom were American. Filipinization of the Supreme Court started only during the Commonwealth, 1935. Administrative Code of 1917 provided for a Supreme Court with a Chief Justice and eight associate Justices. With the ratification of the 1935 Constitution, the membership was increased to 11 with two divisions of five members each. The 1973 Constitution further increased its membership to 15 with two (2) divisions.

Pursuant to the provisions of the 1987 Constitution, the Supreme Court is composed of a Chief Justice and fourteen Associate Justices who shall serve until the age of seventy (70). The Court may sit En Banc or in its three (3) divisions composed of five members each. A vacancy must be filled up by the President within ninety (90) days of occurrence.

Article VIII, sec. 4 (2) explicitly provides for the cases that must be heard En Banc and sec. 4 (3) for cases that may be heard by divisions. (Constitution, Art. VIII, sec. 4, par.1) Judiciary Reorganization Act of 1980 transferred from the Department of Justice to the Supreme Court the administrative supervision of all courts and their personnel. This was affirmed by Art. VIII, sec. 6 of the 1987 Constitution. To effectively discharge this constitutional mandate, The Office of the Court Administrator (OCA) was created under Presidential Decree No. 828, as mended by Presidential Decree No. 842, and and its functions further strengthened by a Resolution of the Supreme Court En Bans dated October 24, 1996. Its principal function is the supervision and administration of the lower courts throughout the Philippines and all their personnel. It reports and recommends to the Supreme Court all actions that affect the lower court management. The OCA is headed by the Court Administrator, three (3) Deputy Court Administrators and three (3) Assistant Court Administrators.

According to the 1987 Constitution, Art. VIII, sec. 5, The Supreme Court exercises the following powers:

Exercise jurisdiction over cases affecting ambassadors, other public ministers and consuls, and over petitions for certiorari, prohibition, mandamus, quo warranto, and habeas corpus.
Review, revise, reverse, modify, or affirm on appeal or certiorari, as the law or the Rules of Court may provide final judgments and orders of lower courts in:

All cases ion which the constitutionality or validity of any treaty, international or executive agreement, law, presidential decree, proclamation, order, instruction, ordinance, or regulation is in question.
All cases involving the legality of any tax, impost, assessment, or toll, or any penalty imposed in relation thereto.
All cases in which the jurisdiction of any lower court is in issue.
All criminal cases ion which the penalty imposed is reclusion perpetua or higher.
All cases in which only an error or question of law is involved.

Assign temporarily judges of lower court to other stations as public interest may require. Such temporary assignment shall not exceed six months without the consent of the judge concerned.
Order a change of venue or place of trial to avoid a miscarriage of justice.
Promulgate rules concerning the protection and enforcement of constitutional rights, pleading, practice, and procedure in all courts, the admission to the practice of law, the Integrated Bar, and legal assistance to the underprivileged. Such rules shall provide a simplified and inexpensive procedure for the speedy disposition of cases, shall be uniform for all courts the same grade, and shall not diminish, increase or modify substantive rights. Rules of procedure of special courts and quasi-judicial bodies shall remain effective unless disapproved by the Supreme Court.
Appoint all officials and employees of the Judiciary in accordance with the Civil Service Law (Sec. 5 , id.).

The Supreme Court has adopted and promulgated the Rules of Court for the protection and enforcement of constitutional rights, pleadings and practice and procedure in all courts, and the admission in the practice of law. Amendments have bee promulgated through the Committee on Revision of Rules. The Court also issues administrative rules and regulations in the form of court issuances and the Supreme Court E-Library website.

The Judicial and Bar Council was created by virtue of Art. VIII, sec. 8. under the supervision of the Supreme Court. Its principal function is to screen prospective appointees to any judicial post. The Judicial and Bar Council has promulgated on October 31, 2000 its Rules (JBC-009) in the performance of its function. It is composed of the Chief Justice as ex-officio Chairman, the Secretary of Justice and representatives of Congress as ex-officio members, a representative of the Integrated Bar, a professor of law, a retired member of the Supreme Court and a representative of the private sector as members.

The Philippine Judicial Academy (PHILJA) is the "training school for justices, judge, court personnel, lawyers and aspirants to judicial posts." It was originally created by the Supreme Court on March 16, 1996 by virtue of Administrative Order No. 35-96 and was institutionalized on February 26, 1998 by virtue of Republic 8557. It is an important component of the Supreme Court for its important mission on judicial education. No appointee to the Bench may commence the discharge his adjudicative function without completing the prescribed court in the Academy.

Court of Appeals

Commonwealth Act No. 3 (December 31, 1935), pursuant to the 1935 Constitution (Art VIII, sec. 1), established the Court of Appeals. It was formally organized on February 1, 1936 and was composed of eleven justices with Justice Pedro Concepcion as the first Presiding Justice. Its composition was increased to 15 in 1938 and further increased to 17 in 1942 by virtue of Executive Order No. 4. The Court of Appeals was regionalized in the later part of 1944 when five District Court of Appeals were organized for Northern, Central and Southern Luzon, for Manila and for Visayas and Mindanao. It was abolished by President Osmena in 1945, pursuant to Executive Order No. 37 due to the prevailing abnormal conditions. However, it was re-established on October 4, 1946 by virtue of Republic Act No. 52 with a Presiding Justice and fifteen (15) Associate Justices. Its composition was increased by the following enactments: Republic Act No. 1605 to eighteen (18); Republic Act No. 5204 to twenty-four (24); Presidential Decree No. 1482 to one (1) Presiding Justice and thirty-four (34) Associate Justices; Batas Pambansa Blg. 129 to fifty (50); Republic Act No. 8246 to sixty-nine (69). With Republic Act No. 8246, the Court of Appeals in Cebu, and Cagayan de Oro were established.

Batas Pambansa Blg. 129 changed the name of the Court of Appeals to Intermediate Appellate Court. Executive Order No. 33 brought back its name to Court of Appeals.

Section 9 of Batas Pambansa Blg. 129 as amended by Executive Order No. 33 and Republic Act No. 7902 provides for the jurisdiction of the Court of Appeals as follows:

Original jurisdiction to issue writs of mandamus, prohibition, certiorari habeas corpus, and quo warrant, and auxiliary writs or processes, whether or not in aid of its appellate jurisdiction;
Exclusive original jurisdiction over actions for annulment of judgment of Regional Trial Courts; and
Exclusive appellate jurisdiction over all final judgments, decisions, resolutions, orders or awards of Regional Trial Courts and quasi-judicial agencies, instrumentalities, boards or commissions, including the Securities and Exchange Commission, the Social Security Commission, the Employees Compensation Commission and the Civil Service Commission, except those falling within the appellate jurisdiction of the Supreme Court in accordance with the Constitution, the Labor Code of the Philippines under Presidential Decree No. 442, as amended, the provisions of this Act, and of subparagraph (1) of the third paragraph and subparagraph (4) of the fourth paragraph of Section 17 of the Judiciary Act of 1948.

The Supreme Court, acting on the recommendation of the Committee on Revision of the Rules of Court, resolved to approve the 2002 Internal Rules of the Court of Appeals (A.M. No. 02-6-13-CA) and amended by a resolution of the Court En Banc on July 13, 2004 (A.M. No. 03-05-03-SC).

Pursuant to Republic Act No. 9372 otherwise known as the Human Security Act of 2007, the Chief Justice issued Administrative Order No. 118-2007, designating the First, Second and Third Divisions of the Court of Appeals to handle cases involving the crimes of terrorism or conspiracy to commit terrorism and all other matters incident to the said crimes emanating from the Metropolitan Manila and Luzon. For those emanating from Visayas, all divisions of the Court of Appeals stationed in Cebu are designated to handle these cases while the Court of Appeals stationed in Cagayan De Oro will handle cases from Mindanao.

Regional Trial Courts

They are called the second level courts and are divided into thirteen (13) judicial regions: National Capital Region (Metro Manila) and the twelve (12) regions of the country, which are divided into several branches. The jurisdictions are defined in sec. 19-23 of Batas Pambansa Blg. 129 as amended by Republic Act No. 7671. The Supreme Court designates certain branches of regional trial courts as special courts to handle exclusively criminal cases, juvenile and domestic relations cases, agrarian cases, urban land reform cases which do not fall under the jurisdiction of quasi-judicial bodies. The Supreme Court may likewise designate specific branches as special courts for heinous crimes, dangerous drugs cases, commercial courts and intellectual property rights violations. Some branches of the Regional Trial Courts have been designated as family courts (A.M. No. 99-11-07) because the family courts to be established pursuant to Republic Act No. 8369 of the Family Court Law of 1997 have not yet been organized. Pursuant to Republic Act No. 8369, the Family Court Law of 1997, some branches of the Regional Trial Courts have been designated as family courts (A.M. No. 99-11-07).

The Regional Trial Courts' jurisdictions are defined as follows:

Exercise exclusive original jurisdiction in Civil Cases as follows:

All civil actions in which the subject of the litigation is incapable of pecuniary estimation;
