# Marvic Leonen

Marvic Mario Victor Famorca Leonen (born December 29, 1962) has been the Senior Associate Justice of the Supreme Court of the Philippines since May 14, 2022, following the retirement of Senior Associate Justice Estela Perlas-Bernabe. He became an associate justice of the Supreme Court of the Philippines on November 21, 2012, making him the second-youngest jurist to hold the position, and the youngest since Manuel V. Moran in 1938. Before joining the Supreme Court, he served as chief peace negotiator of the Republic of the Philippines in peace talks with the Moro Islamic Liberation Front. Leonen is sometimes called "The Great Dissenter" for his liberal and human rights-oriented decisions, often in opposition to the more conservative justices close to Rodrigo Duterte.
Leonen was the dean of the University of the Philippines College of Law at University of the Philippines Diliman from 2008 to 2011, and is known for his work in environmental activism and community organizing.

## Early life

Mario Victor Famorca Leonen was born on December 29, 1962, to lawyer Mauro Leonen (d. 1970) and Adrelina Famorca. His parents married in Vigan, Ilocos Sur, but settled in Baguio City, Benguet, where he was born. He is the second of six children and is of Ilocano ethnicity.
His mother is a pharmacist and housewife. His father was a human rights lawyer who represented indigenous Ibaloi people in land title disputes. Mauro died in a car accident in San Manuel, Tarlac on June 26, 1970.
Leonen decided to pursue a legal career in the second grade.

## Education and early career

After attending St. Theresa's College for elementary school and graduating as valedictorian from Saint Louis University-Boys' High School, Leonen graduated magna cum laude with a degree in economics from the University of the Philippines Diliman in 1983. During the academic year 1982–1983, he chaired Economics Toward Consciousness, a student organization based in the University of the Philippines School of Economics, He obtained his law degree from the university's College of Law in 1987, graduating in the top four of his class.
In his senior year, Leonen joined the free legal assistance group in 1988 and remained a member until his appointment to the Supreme Court in 2012. That year, he co-founded the Legal Rights and Natural Resources Center, Inc.-Kasama sa Kalikasan, a legal and policy research and advocacy institution that provides legal services to upland rural poor and indigenous people's communities. He served as the center's executive director for 15 years. He then attended Columbia University and where he earned a Master of Laws degree.

## Academic career

Leonen joined the law faculty in 1989 as a professorial lecturer in Philippine Indigenous Law. He became an assistant professor during Dean Pacifico Agabin's term and began working as an academic administrator under Dean Merlin M. Magallona. In 2000, he became the university general counsel, and in March 2005, he became the first vice president for legal affairs of the UP System. Leonen has taught 20 different subjects in the law school.
He also directed the college's clinical legal education program and has lectured and been a resource speaker at national and international forums in Hong Kong, Thailand, Malaysia, Indonesia, Japan, Spain, Netherlands, Australia, Estonia, and the United Kingdom.
In 2008, the Board of Regents of the UP System selected him as the Dean of the University of the Philippines College of Law at UP Diliman. He served as dean until Danilo L. Concepcion was appointed in June 2011.
Leonen has also provided legal commentary for television networks such as ABS-CBN and GMA Network during events such as the 2000-2001 impeachment trial of President Joseph Estrada.

## Government chief peace negotiator (2010–2012)

In July 2010, President Benigno Aquino III named Leonen as the Philippine government's chief negotiator with the Moro Islamic Liberation Front. Under his leadership, the government successfully created a framework agreement with the MILF to establish the Bangsamoro political entity, replacing the Autonomous Region for Muslim Mindanao. His performance was praised, bringing new hopes for lasting peace in war-torn Mindanao.

## Service in the Supreme Court of the Philippines

On November 21, 2012, President Benigno Aquino III appointed Leonen as the 172nd Associate Justice of the Supreme Court of the Philippines at the age of 49, making him the youngest justice named to the Court since 1938.
In Belgica v. Executive Secretary, the landmark case where the Court declared the Priority Development Assistance Fund unconstitutional, Leonen wrote a separate concurring opinion demonstrating a command of logic and the law to support the unconstitutionality of pork barrel. He stated, "A member of the House of Representatives or a Senator is not an automated teller machine from which the public can withdraw funds for sundry private purposes."
In civil law, Leonen penned many notable decisions, including Tan-Andal v. Andal, which removed the requirement of medical or expert witnesses for declaring a marriage null due to psychological incapacity under the Family Code. The new rule requires only totally antagonistic personality structures resulting in the inevitable breakdown of the marriage. The incapacity to fulfill essential marital obligations need only be manifest specifically toward that spouse to declare the marriage void ab initio.

### Dissents

   * Marvic Leonen @marvicleonen
   Even if the Chief Justice has failed our expectations, quo warranto, as a process to oust an impeachable officer and a sitting member of the Supreme Court, is a legal abomination. It creates a precedent that gravely diminishes judicial independence and threatens the ability of this Court to assert the fundamental rights of our people.
Leonen is known for his frequent dissents. In an interview with Rappler, he stated that while his point of view might often be "before its time,"$^{:@47:50}$ he is not frustrated by dissenting, as the reasoning in his dissent might be relied upon by the majority in the future,$^{:@49:00}$ citing Holmes' dissent in Abrams v. United States as an example.$^{:@34:00}$
Among Leonen's notable dissents is his argument in Disini v. Secretary of Justice that criminal libel and cyberlibel are unconstitutional vestiges of American and Spanish colonialism. He is also noted for his dissent in Republic v. Sereno, calling the majority's decision a "legal abomination." In Lagman vs. Pimentel III, a case addressing the legality of extending martial law and suspending the privilege of the writ of habeas corpus in Mindanao, Leonen explained that Congress had abused its discretion because there was no proper presentation of facts, no examination of the allegations by the military, and no ascertainment of why a longer extension was needed despite the continued declaration of military victory.

### As Bar Chairperson of the 2020-2021 Bar Examination

In the Philippines, the Supreme Court administers the Bar Examinations and each year, a Supreme Court Justice becomes the Bar Chairperson. Leonen was to be the chairperson for the 2020 Bar Exams (postponed), but his term was extended to the 2021 batch due to the COVID-19 pandemic.
While the exam date was pending, the Supreme Court kept examinees informed by posting instructions at the Bar Bulletins, and Leonen regularly posted updates and motivations on Twitter using the hashtag "#BestBarEver2020_21".
The exam was initially scheduled for November 2021 but was moved to the four Sundays of January 16, 23, 30, and February 6, 2022. It was then held on February 4 and 6, 2022, in response to scientific recommendations and compliance with COVID-19 related orders. The exam took place in 31 localized testing sites nationwide, each adhering to pandemic protocols and cooperating with local law enforcement.
This batch produced 8,241 newly licensed lawyers out of 11,402 examinees, including 761 "exemplary passers" (grades from 85 to 90%) and 14 "excellent passers" (grades above 90%). Leonen replaced the word "fail" with "did not pass" or "did not finish" for those who did not score 75% or higher.

### The New Lawyer's Oath

The Supreme Court En Banc approved the Code of Professional Responsibility and Accountability (CPRA) on April 11, 2023, after a nationwide caravan with members of the legal community and the public. The new CPRA was launched on April 13, 2023, at the Manila Hotel before members of the legal community. The event included the introduction of the New Lawyer's Oath, authored by Senior Associate Justice Leonen.

### Proposed Writ of Kalayaan

On May 25, 2024, Leonen announced at his Integrated Bar of the Philippines Caloocan-Malabon-Navotas Chapter lecture at the Manila Hotel that the Supreme Court of the Philippines was drafting the "Writ of Kalayaan," a writ and constitutional remedy to address prison overcrowding of detention suspects (PDLs) and protect their human and legal rights. The World Prison Brief ranks the Philippines third in prison occupancy (362%). The Commission on Audit's 2022 review revealed that 323 of 478 jails are congested. However, on October 19, 2023, Bureau of Corrections's Gregorio Catapang Jr. contradicted the legal remedy recommended by the SC’s judicial panel "Committee on Human Rights and International Humanitarian Law" on December 19, 2022, citing Republic Act 10575 (Bureau of Corrections Act of 2013), RA 11928, and the Department of Justice's 5-year Development and Modernization Plan 2023-2028.

## Impeachment complaint

In December 2020, Edwin Cordevilla, claiming to be the secretary general of the Filipino League of Advocates for Good Government and represented by lawyer Larry Gadon, filed an impeachment complaint against AJ Marvic Leonen. The complaint alleged that SAJ Leonen had been “incompetent and negligent” for failing to resolve 37 cases within the required period and lacked integrity for not filing his SALN for 15 years.
Under the 1987 Constitution of The Philippines, grounds for impeachment include culpable violation of the Constitution, treason, bribery, graft and corruption, other high crimes, or betrayal of public trust. Leonen was accused of culpable violation of the Constitution for failing to resolve cases in a timely manner and betrayal of public trust for not filing his SALN.
Despite the likelihood of a trial, Leonen received public support, especially from the legal and academic community. On December 10, 2020, the UP College Of Law released a statement dismissing the impeachment complaint, stating that Leonen “has expressed consistently, in his decisions and dissents, a commitment to academic rigor, principled discourse, creative expression, and courageous authenticity” and that the act was “a latest assault to send our nation further down the dark road, especially while a global pandemic still hangs over all our heads and threatens to bring our society into despair and destitution.” Senator Risa Hontiveros also called the impeachment unnecessary and counterproductive, deeming it a “distraction that will only drag lawmakers and the public into a pointless political fiasco” amid the pandemic.
On May 27, 2021, the impeachment hearing began, and 44 lawmakers immediately found the complaint lacked sufficient evidence.
Under the Philippine Rules of Court, “a witness can testify only to those facts which he knows of his personal knowledge; that is, which are derived from his own perception, except as otherwise provided in these rules (Section 36 of Rule 130).” The supporting documents used were photocopies or newspaper articles that did not manifest personal knowledge or authentic records, proving the case groundless.
Leonen released a statement via his Chambers, posted on his Twitter account, expressing thankfulness for the support from lawyers, professors, and other workers in the Judiciary, adding that "[we] must courageously focus on the essentials: do what is right at the right time in the right way, serve our people and serve them well."

## Notable talks

Senior Associate Justice Marvic M.V.F. Leonen is a public speaker on Philippine law and related causes and is often invited to give motivational speeches at public and academic events such as graduations and oath-takings. His popular talks include his 2013 TEDxDiliman talk, where he discusses why lawyers matter:
   "I suspect I should ask more sympathy from you, one because I'm following Joey Ayala, who probably did an illegal act here. [crowd's laughter] Probably lang, we would have to discuss that in the Supreme Court [crowd's laughter].
   And second is that I was given a very difficult task which is in the next 18 minutes, I have to convince you that lawyers matter; [crowd's laughter]And, well, I'm used to very difficult task, you know- talking with the largest insurgent group in the country and asking them to sign a framework agreement that's very difficult that it took me two years, not 18 minutes. But in any case, I'd like to start with 1979 when I entered the University of the Philippines knowing that's what I wanted to do was to become a lawyer. I entered the portals of this; College- the School Of Economics. And at that time we were only starting to discover that Martial Law was not what it was meant to be; that there were there was pervasive poverty all around; and human rights violations were happening. I entered the UP College of Law in 1983 in the following year- Ninoy Aquino was shot, Lean Alejandro was assassinated and we were on the streets walking and asking that the dictator to come down. And of course, at that time, we saw that the law was not, also, what it was meant to be.
   I became a FLAG lawyer, I joined the free legal assistance group, and one of the first cases that were given to me, was a raid of a shanty in Novaliches and they found some firearms over there and they asked me to do the impossible, which was to try to have the persons acquitted of Illegal Possession Of Firearms. But they had firearms, and so, I thought, "Is this what what the lawyer is supposed to be?". So I thought to myself, "What should I do?" Then I remember Constitutional Law Article 3 Section 2, "The right of the people to be secure in their persons, places, papers and effects against unreasonable searches and seizures shall be inviolable. And no search warrant or warrant of arrest shall issue except upon probable cause to be determined by the judge after particularly describing the place", Wait a minute, quote and quote, "after particularly describing the place to be searched", Wait a minute! I looked up the warrant- unnumbered shanty! So I moved to quash and move to exclude evidence. It was granted. My clients were acquitted. They were NPA people but now they rejoined Society.
   So that was one of my first successes as a lawyer. And buoyed by that, inspired by that, we thought that law mattered for people for whom law is very real. So what we did was set up the Legal Rights and Natural Resources Center. We scoured the country, work with Indigenous' Peoples Groups, went up mountains- Mount Apo several times- six times, I think, with Joey Ayala. And then we found out that there was a commercial, geothermal power plant that was about to be constructed, right at the heart of the ancestral domain of the Bagobo. So what did we do as lawyers? We crafted the 57-page petition, which we thought was very creative. First and foremost, it was a protected area. And at the middle of the protected area, they were going to put a commercial project. A commercial geothermal power plant and we thought arguing that, in a protected area in the concept of the law, in the idea of what the protected area was, as we imported from developed countries- there should be no commercial activity inside, first argument.
   Second argument. This was the first and environmental impact statement assessed by the DENR and we thought that it was high time because there was Section 16 of Article 2 of The Constitution that the rhythm of harmony and nature required that the Court extended its judicial review more strictly into administrative cases coming from the DENR, so that not only substantial evidence could be examined but they would look up the use of science in terms of the environmental impact statement. Very good arguments. Very brilliant, very creative. It is so we filed it with the Supreme Court, and the Supreme Court issued, a one-page decision dismissing our case outright without even asking the respondents to file a comment. But undeterred because we have faced the community, we have faced a civil society, we were faced an entire movement wanting to prevent the invasion of Apo Sandawa or Mt. Apo at that time, we filed a motion for reconsideration. Again, arguing the same point, but citing more law journals and more jurisprudence on our side. The motion for reconsideration was longer than the petition. And finally the Supreme Court again, came out with a one-page decision. This time in one paragraph. It says, "Dismissed. No substantial argument raised". And that was our case in Mount Apo. But we did not lose heart because we saw that the law has to be argued at the right time.
   So that in some time in the year 2000, faced with the community that was saying that it was facing the largest mining concession ever awarded in this country 95 thousand hectares. As far as your eye can see, is 400 hectares on all ends. 94,000 struggles for provinces in Mindanao. So what we did for them was craft a petition, which was entitled La Bugal Tribal Association vs DENR. Our argument was very simple: The constitution of the Republic of the Philippines in Article 12 Section 4 said: only financial, either financial or technical assistance agreement would be allowed to any fully owned foreign concession in this country. This was a change from our Old Constitution. Now, this concession that's fully owned, but they operated they would manage they would provide financial assistance and technical assistance. It was an "and" and not an "or". So we filed with the Supreme Court arguing our case. That the intension of The Sovereign people expressed in the Constitution was to declare this law as unconstitutional. January 2004 with the majority of 8-for 6-against and 1 taking no part Supreme Court of the Republic of the Philippines.
   Declared that the first FPAA in this country. The first largest fully foreign owned mining concession in this country was unconstitutional, null and void ab initio. We celebrated, we went up the mountain. We told our people that this is how the law moves. This is your Constitution. You are part of the Republic of the Philippines. But then, there was a motion for reconsideration that was filed and the motion for reconsideration was heard by the Supreme Court. No less than two retired justices arguing for the Chamber Of Mines and we argued as best as we could, I stood there for eight hours in front of the Supreme Court en banc and they stood there for a light number of hours arguing their case. By December of that same year, the vote was 10–4–1, and we lost the case. It was reversed in a span of 11 months, the Supreme Court, read that provision in a different way. And we had to go up to the community to explain to them why you law still mattered, and it was a difficult way to explain to them.
   That is what the law is. Sometimes it is for you. Sometimes, it's against you.
   But why does why does the law matter and why you lawyers matter? For simple reason, first is because the law is real. Because there is a law, police can come to get you. You will be caught for color coding, you will be arrested for some kind of an offense, including singing the National Anthem in the wrong way [crowd's laughter]. I'm just saying; [crowd's laughter]. So, Popo is a lawyer[crowd's laughter]; [crowd's laughter], maraming huhulihin kayo lahat, di ako nakinig di ako kumanta di ako kasama [crowd's laughter] . The law is real for people who need the law. For instance, a daughter that is raped by a father 11 times. We just made that ruling a week ago. The law is real for people who need to go against a tax person who is asking them to pay more than what they do. Therefore, you will need lawyers.
   Second reason that lawyers matter is that because the law evolves. Before when we fired the Mount Apo, our case there was no Writ Of Kalikasan. Now, there is one- lawyers drafted it. Before when we were counsels to the families of involuntarily disappeared, all we had was a Writ Of Habeas Corpus. Today, you can have a Writ Of Amparo and more than that. You can have the Writ Of Habeas Data. Before we cannot argue Ancestral Domain. Today, you have the Indigenous Peoples Rights Act. Before you cannot argue environment. Today, you can, you can get a Writ Of Kalikasan in any of the levels of our court and we have issued a Writ of Kalikasan on for several projects in the Court. Lawyers will help you adjust the law in order that of course more people will be assisted and of course in order to balance the needs of our country for commercial development and the need for our country for soldiers, social justice. The third reason that lawyers matter is because the law helps us understand ourselves. Sure. There are concepts of property, which defines who to us is an agricultural tenant, and who is a land owner. But our concepts of property; also say, that property is about social justice. That property can be limited. Hence, you have limitations on your exercise of property taking into consideration the environment.
   We have nuisance provisions in the law and you have provisions both in treaty and in the law saying that in times of War, whether it be of full-blown Wars between two states, or wars of are known as armed conflicts of a non-international character, such as what happened in Zamboanga, that civilians are to be protected. They tell us that civilians are important. Of course, we still have to struggle because laws evolve.
   Men can only commit adultery, women can, ah, concubinage, I'm sorry, women can only commit adultery. Prostitutes are criminals. We have, we still have a lot to do. The only way that you can separate from your spouse. Well, one of the ways that you can separate from your spouse; [crowd's laughter]. Believe me. I've experienced in this; [crowd's laughter], the only way that I, one of the things that you can separate from your spouse is to actually prove the condition called "psychological incapacity", a concept of only one religious sect within our country and not of all, but still this law exists. They can evolve, they tell us who we are. And therefore, it is important that we are lawyers who understand you, and therefore try to change it. So that how we constitute ourselves, how we understand our identity is there. And by the way, Bangsamoro will be soon a law, not a minority, but one of the legitimate identity within our country.
   And the fourth reason I think most important that lawyers matter is because lawyers are a luxury. You only go to lawyers in times of need. Unless they are your friends in which case you have drinks with them, not because they're a lawyer, they start talking about the law. They start becoming boring [crowd's laughter]. But normally, you would want to go to a lawyer only when you are at the end of your rope. When you are actually faced with time in prison, when you are actually faced with an assessment from the BIR. When you're actually faced with the need to settle your domestic resources, when you're actually faced with conditions, like a mining company entering your ancestral domain.
   Here is an example of a situation which was caused by a lawyer: a lawyer got a TRO to stop a mining firm from entering mountains in Nueva Vizcaya. And she was a very diminutive individual, very petite, but she was able to get a writ in order to stop a mining company there. You would certainly go to a lawyer at that time.
   Hence, lawyers matter because they will hold your hand. Because they are the ones that should attend to you with compassion, because they are the ones who will sit with you, in your times of trouble. Even with your spouses, even with your enemies. They are the ones who will be there and you will stick with you, hopefully with or without the payment of attorney's fees [crowd's laughter] until the very end. And because they need to be there. Therefore, lawyers matter.
   We need lawyers. We need good lawyers. We need lawyers who understand that they are not a joke. We need lawyers to understand that their careers are not careers. It is a profession. It is a passion and I tell you that is why lawyers matter.
   I am Marvic Leonen. I am a lawyer."
