The Katipunan's revolution led to the Tejeros Convention where, at San Francisco de Malabón, Cavite, on March 22, 1897, the first presidential and vice presidential elections in Philippine history were held—although only Katipuneros (members of the Katipunan) were able to take part, and not the general populace.
A later meeting of the revolutionary government established there, held on November 1, 1897 at Biak-na-Bato in the town of San Miguel de Mayumo in Bulacán, established the Republic of Biak-na-Bato.
The republic had a constitution drafted by Isabelo Artacho and Félix Ferrer and based on the first Cuban Constitution. It is known as the "Constitución Provisional de la República de Filipinas", and was originally written in and promulgated in the Spanish and Tagalog languages.

9. Preamble of malolos constitution

10. 1935:the Commonwealth Constitution
The 1935 Constitution of the Philippines was written in 1934, approved and adopted by the Commonwealth of the Philippines ( ) and later used by the Third Republic of the Philippines ( ). It was written with an eye to meeting the approval of the United States Government as well, so as to ensure that the U.S. would live up to its promise to grant the Philippines independence and not have a premise to hold on to its "possession" on the grounds that it was too politically immature and hence unready for full, real independence.
The original 1935 Constitution provides, inter alia, for a unicameral Legislature and a single six-year term for the President. It was amended in 1940 to have a bicameral Congress composed of a Senate and House of Representatives, as well the creation of an independent Commission on Elections. The Constitution limited the President to a four-year term with a maximum of two consecutive terms in office.

11. Acts of the United States Congress
The Philippines was a United States Territory from December 10, 1898 to March 24, 1934[17] and therefore under the jurisdiction of the Federal Government of the United States. Two acts of the United States Congress passed during this period can be considered Philippine constitutions in that those acts defined the fundamental political principles and established the structure, procedures, powers and duties of the Philippine government.
Philippine Organic Act of 1902
The Philippine Organic Act of 1902, sometimes known as the "Philippine Bill of 1902" or the "Cooper Act", was the first organic law for the Philippine Islands enacted by the United States Congress. It provided for the creation of a popularly elected Philippine Assembly, and specified that legislative power would be vested in a bicameral legislature composed of the Philippine Commission (upper house) and the Philippine Assembly (lower house). Its key provisions included a bill of rights for the Filipinos and the appointment of two non-voting Filipino Resident Commissioner of the Philippines to represent the Philippines in the United States House of Representatives.
Philippine Autonomy Act of 1916
The Philippine Autonomy Act of 1916, sometimes known as "Jones Law", modified the structure of the Philippine government by removing the Philippine Commission as the legislative upper house and replacing it with a Senate elected by Filipino voters, creating the Philippines' first fully elected national legislature. This act also explicitly stated that it was and had always been the purpose of the people of the United States to end their sovereignty over the Philippine Islands and to recognise Philippine independence as soon as a stable government can be established therein.
Tydings–McDuffie Act (1934)
Though not a constitution itself, the Tydings–McDuffie Act of 1934 provided authority and defined mechanisms for the establishment of a formal constitution via a constitutional convention.

12. Preamble of commonwealth constitution
The Filipino people, imploring the aid of Divine Providence, in order to establish a government that shall embody their ideals, conserve and develop the patrimony of the nation, promote the general welfare, and secure to themselves and their posterity the blessings of independence under a regime of justice, liberty, and democracy, do ordain and promulgate this constitution."

13. 1973: constitutional Authoritarianism
On 24 August 1970, Congress enacted RA No. 6132, otherwise known as the Constitutional Convention Act, for the purpose of convening a Constitutional Convention.
While in the process of drafting a new Constitution, President Ferdinand Marcos declared Martial Law on 21 September 1972
The 1973 Constitution, promulgated after Marcos' declaration of martial law, was supposed to introduce a parliamentary-style government. Legislative power was vested in a unicameral National Assembly whose members were elected for six-year terms. The President was ideally elected as the symbolic and purely ceremonial head of state chosen from amongst the Members of the National Assembly for a six-year term and could be re-elected to an unlimited number of terms. Upon election, the President ceased to be a Member of the National Assembly. During his term, the President was not allowed to be a member of a political party or hold any other office.

14. From 16–17 October 1976, a majority of barangay voters (also called "Citizen Assemblies") approved that martial law should be continued and ratified the amendments to the Constitution proposed by President Marcos.
The 1976 amendments were:
an Interim Batasang Pambansa (IBP) substituting for the Interim National Assembly;
the President would also become the Prime Minister and he would continue to exercise legislative powers until such time as martial law was lifted.
The Sixth Amendment authorized the President to legislate on his own on an "emergency" basis:
Whenever in the judgement of the President there exists a grave emergency or a threat or imminence thereof, or whenever the Interim Batasang Pambansa or the regular National Assembly fails or is unable to act adequately on any matter for any reason that in his judgment requires immediate action, he may, in order to meet the exigency, issue the necessary decrees, orders or letters of instructions, which shall form part of the law of the land.

15. Preamble of 1973 constitution
We, the sovereign Filipino people, imploring the aid of Divine Providence, in order to establish a Government that shall embody our ideals, promote the general welfare, conserve and develop the patrimony of our Nation, and secure to ourselves and our posterity the blessings of democracy under a regime of justice, peace, liberty, and equality, do ordain and promulgate this Constitution.

16. 1987: Freedom constitution (constitution after martial Law)
On February 11, 1987, the new constitution was proclaimed ratified and took effect.
Establishes the Philippines as a "democratic and republican State", where "sovereignty resides in the people and all government authority emanates from them".
Corazon Aquino issued Proclamation No. 3, declaring a national policy to implement the reforms mandated by the people, protecting their basic rights, adopting a provisional constitution, and providing for an orderly translation to a government under a new constitution.
The 1987 Constitution established a representative democracy with power divided among three separate and independent branches of government: the Executive, a bicameral Legislature, and the Judiciary. There were three independent constitutional commissions as well: the Commission on Audit, the Civil Service Commission, and the Commission on Elections. Integrated into the Constitution was a full Bill of Rights, which guaranteed fundamental civil and and political rights, and it provided for free, fair, and periodic elections.

17. Executive branch
The Executive branch is headed by the President and his appointed Cabinet. The President is the head of the state and the chief executive, but he is subject to significant checks from the other branches, especially in times of emergency, which, given the history of the country, was obviously intended to be a safeguard against a repeat of Marcos’ martial law despotism.
For example, in cases of national emergency, the President can still declare martial law, but not for a period longer than 60 days. Congress can revoke this decision by a majority vote, or it can also extend it for a period to be determined by the Congress. Additionally, the Supreme Court can review the declaration to decide if there were sufficient facts to justify martial law.
The President can grant pardons and amnesty. He is also empowered to make or accept foreign loans. He cannot, however, enter into treaties without the consent of the Senate. The President and Vice-President are elected at large by a direct vote, but the President may only serve one 6-year term. The Cabinet, consisting of the President’s advisers and heads of departments, is appointed by the President and it assists him in his governance functions.

18. Legislative branch
The legislative power is vested in a Congress which is divided into two Houses, the Senate and the House of Representatives. The 24 members of the Senate are elected at large by a popular vote and can serve no more than two consecutive 6-year terms.
The House is composed of 250 elected members. Most of these Representatives are elected by district for 3-year terms, but 20% of the total membership is chosen in proportion to party representation. Besides the exclusive power to legislate, one of the most important powers of Congress is the ability to declare war, which it can through a two-thirds vote in both houses.
Even the power to legislate, however, is subject to an executive check. The President retains the power to veto a bill passed by both houses, and Congress may override this veto only with a two-thirds vote in both houses.

19. Judicial branch
The Court system in the Philippines exercises the judicial power of government and it is made up of a Supreme Court and lower courts created by law. The Supreme Court is a 15- member court appointed by the President without need for confirmation by Congress. Appointment, however, is limited to a list of nominees presented to the President by a constitutionally-specified Judicial and Bar Council.
This Council consists of 7 members: the Chief Justice of the Supreme Court, the Secretary of Justice, a representative from Congress, a representative of the Integrated Bar, a professor of law, a retired member of the Supreme Court, and a representative of the private sector. The first four serve for four years, the law professor for three, the retired Justice for two, and the private sector representative for one year.
The Supreme Court Justices may hear, on appeal, any cases dealing with the constitutionality of any law, treaty, or decree of the government, cases where questions of jurisdiction or judicial error are concerned, or cases where the penalty is sufficiently grave. It may also exercise original jurisdiction over cases involving government or international officials. The Supreme Court also is charged with overseeing the functioning and administration of the lower courts and their personnel.

20. Changing of the constitution
Constitutional reform in the Philippines, also known as Charter Change (colloquially Cha-Cha) refers to the political and legal processes needed to amend the current 1987 Constitution of the Philippines. Under the common interpretation of the Constitution, amendments can be proposed by one of three methods: a People's Initiative, a Constituent Assembly or a Constitutional Convention.

21. People's Initiative (or "PI") is a common appellative in the Philippines that refers to either a mode for constitutional amendment provided by the 1987 Philippine Constitution or to the act of pushing an initiative (national or local) allowed by the Philippine Initiative and Referendum Act of The appellative also refers to the product of either of those initiatives.
A Constitutional Convention, is one of the three methods to amend the Constitution of the Philippines. The others are a People's Initiative or a Constituent Assembly. Article XVII, Section 3 of the Constitution says, "The Congress may, by a vote of two-thirds of all its Members, call a constitutional convention, or by a majority vote of all its Members, submit to the electorate the question of calling such a convention.
The Constituent Assembly, is a term describing one of the three methods by which amendments to the 1987 Constitution of the Philippines may be proposed. The other two modes are via People's Initiative and Constitutional Convention. All three require a majority vote in a national referendum.
Constituent Assembly is composed of all members of the bicameral Congress of the Philippines (Senate and the House of Representatives). It is convened by Congress to propose amendments to the 1987 constitution. Under Article XVII of the Constitution of the Philippines, amendments pass upon a vote of three fourths of all members of Congress, but it is not clear if the Congress should vote as a single body or as separate houses. The convention of Congress into a Constituent Assembly is not explicitly provided for in the Constitution, since the term "Constituent Assembly" is not used in the Constitution.

22. Proposed amendments or revision to the 1987 Constitution
Ramos Administration
The first attempt to amend the 1987 Constitution was under President Fidel Ramos. Among the proposed changes in the constitution included a shift to a parliamentary system and the lifting of term limits of public officials. Ramos argued that the changes will bring more accountability, continuity, and responsibility to the "gridlock"-prone Philippine version of presidential bicameral system. Some politically active religious groups, opposition politicians, business tycoons and left-wing organizations opposed the process that was supposed to lead to a national referendum. Critics argued that the proposed constitutional changes for one would benefit the incumbent, Ramos. On September 21, 1997, a church-organized rally brought in an estimated half a million people to Rizal Park.
Furthermore, on September 23, 1997, the advocates suffered a setback when the Supreme Court, under Chief Justice Andres Narvasa, narrowly dismissed a petition filed by the People's Initiative for Reform, Modernization and Action (PIRMA), which sought to amend the Constitution through a signature campaign or People's Initiative. The Supreme Court dismissed the petition on the grounds that the People's Initiative mode does not have enough enabling law for the proposed revisions or amendments in the 1987 constitution.

23. Estrada Administration
Under President Joseph Estrada, there was a similar attempt to change the 1987 constitution. The process is termed as CONCORD or Constitutional Correction for Development. Unlike Constitutional Reform under Ramos and Arroyo the CONCORD proposal, according to its proponents, would amend only the restrictive economic provisions of the constitution that are considered to impede the entry of more foreign investments in the Philippines.
There were, once again, objections from opposition politicians, religious sects and left-wing organizations based on diverse arguments such as national patrimony and the proposed constitutional changes would be self-serving. Again, the government was accused of pushing constitutional reform for its own vested interests.
Arroyo Administration
Endorsed a constitutional change through a constituent assembly, which entails a two-thirds vote of the House to propose amendments or revision to the constitution. This initiative was alos not successful since the term of President Arroyo was mired in controversy and scandal, including the possibility of arroyo extending her term as president, which the constitution does not allow.

24. Aquino III administration
President Benigno Aquino III had no concrete plans regarding constitutional reform, but several proposals were put forth by different members of Congress. Senate Resolution No. 10, by Senator Pimentel, called for constitutional reform to convert to a federal republic. Belmonte's joint resolution on economic provisions. They filed a bill pushing for a federal and parliamentary government, in addition to economic liberalization.
Duterte administration
During the May 2016 election, Rodrigo Duterte stated in May 2016 that a plebiscite on the proposed replacement of the unitary state with a federal one will be held in two years.
After winning, Duterte proposed to revive the proposed form of Nene Pimentel.On December 7, 2016, President Duterte signed Executive Order No. 10 creating a consultative committee (ConCom) to review the 1987 Constitution.Then on July 3, 2018, the ConCom unanimously approved the draft constitution through voting. It was submitted to the President on or before July 9 of the same year.
Referred to as the "Bayanihan Constitution" (referring to the Filipino value of communal work) by Duterte and the consultative committee the proposed federal charter includes an amendment that aims to prohibit elected officials from switching political parties during the first and last two years of their term, as a response to turncoat behavior. Also included are provisions that seek to ban political dynasties, barring "persons related within the second civil degree of consanguinity or affinity" from running for public office "simultaneously for more than one national and one regional or local position."

25. federalism
Federalism is a proposed type of government wherein sovereignty is constitutionally divided between the national government and sub divisional governments (such as states or provinces). Federalism divides the country into several autonomous states with a national government.
How federalism works?
The autonomous states are even further divided into local government units. They will have the main responsibility over developing their local industries, public health and safety, education, transportation, and culture. These states have more power over their finances, policies, development plans, and laws.
