Twelve Seats, One Institution:
Why Avelino v. Cuenco Still Matters
in the Senate Quorum Dispute
The current Senate impasse should not be treated as a mere contest of personalities. It is not only a dispute between blocs, nor simply a quarrel over who should preside, who should control committees, or who should manage the chamber’s impeachment timetable. At its core, it is a question of institutional continuity: whether the Senate may function when attendance itself is being used as a political instrument.
The controversy turns on a deceptively simple issue: whether twelve senators can constitute a quorum in a chamber constitutionally composed of twenty-four members.
Those who reject the twelve-senator quorum argument insist that the answer is plain. The Senate has twenty-four members; a majority is thirteen. The Senate Rules require a majority vote of all members for the election of officers. Therefore, they argue, twelve cannot act for the Senate, no matter the surrounding circumstances. To them, “all” means all twenty-four duly elected senators, not twenty-two, not a reduced number, and not a number adjusted by political circumstance.
That position has force. In the ordinary course of Senate business, thirteen is the safer and more conventional number. The Rules cannot be treated as optional. A chamber that begins adjusting numbers for political convenience risks reducing procedure into improvisation.
But the matter does not end there. Philippine constitutional law is not built on arithmetic alone. It is built on constitutional text, legislative rules, institutional practice, and jurisprudence. That is why Avelino v. Cuenco remains central to the present debate.
The Senate Crisis as Institutional Risk
The recent Senate dispute is not an academic exercise. It affects leadership, committee control, impeachment proceedings, legislative priorities, and the ability of the chamber to function at all. When a faction can prevent business by refusing to appear, quorum becomes more than a procedural question. It becomes an instrument of power.
That is why the public should be wary of both extremes. One extreme says twelve is never enough because twenty-four always means thirteen, regardless of circumstance, obstruction, vacancy, incapacity, or impossibility. The other extreme says Avelino allows twelve senators to proceed whenever a political opening appears. Both positions are defective.
The first ignores jurisprudence. The second risks abusing it. The better view is more disciplined: thirteen is the normal quorum in a full twenty-four-member Senate, but Avelino v. Cuenco remains controlling jurisprudence in extraordinary circumstances where rigid arithmetic would reward obstruction and paralyze the institution.
This is not a minor distinction. It is the distinction between law and factional convenience.
What Avelino v. Cuenco Decided
In Avelino v. Cuenco, decided in 1949, the Supreme Court confronted a Senate crisis involving a walkout, a disputed presiding officer, and the election of Mariano Cuenco after only twelve senators proceeded with the session. The objection then was much the same as the objection now: if the Senate had twenty-four members, how could twelve constitute a quorum?
The Court did not treat the matter as a simple mathematical exercise. It examined the actual circumstances surrounding the walkout, the inability or unavailability of certain senators, and the danger that absence could be used to immobilize the chamber. The Court ultimately allowed Cuenco’s election to stand.
That is the living doctrine of Avelino: quorum cannot be used as a weapon to murder the institution.
The decision does not mean twelve is always enough. It does not mean that any faction with twelve senators can reorganize the Senate at will. It does not mean the Senate Rules may be ignored. It does not convert every absence into legal nonexistence.
But it does mean that the law must take institutional reality into account. Where attendance is being strategically manipulated, where the chamber’s ability to function is being deliberately frustrated, or where certain senators cannot realistically be counted for purposes of attendance, the Constitution cannot be read as a suicide pact.
The quorum rule exists to ensure legitimate deliberation. It was not created to reward sabotage.
The Weakness of the “1935 Constitution” Argument
Some now say Avelino should be discarded because it was decided under the 1935 Constitution. That argument is weak. It is not legal reasoning. It is selective amnesia.
If every doctrine decided under an earlier Constitution automatically died with the arrival of a new charter, Philippine public law would be unstable to the point of absurdity. Cases decided under the 1935 Constitution would be treated as obsolete. Cases decided under the 1973 Constitution would be treated as contaminated. Statutes passed during the Batasang Pambansa period would be viewed as inherently suspect. By that logic, large portions of our legal order would have to be buried every time the country changes constitutional regimes.
That cannot be right. A republic cannot rebuild its jurisprudence from zero every time it adopts a new Constitution. Unless a doctrine has been expressly overturned, contradicted by the new constitutional text, or rendered obsolete by later law, it remains part of the legal order.
Legal continuity is not nostalgia. It is institutional discipline. The same country whose courts have long drawn from American jurisprudence in landmark cases cannot suddenly pretend that precedent has an expiration date. Philippine constitutional law has always been cumulative. It carries forward doctrines unless there is a clear legal reason to abandon them.
To throw away Avelino merely because it came from the 1935 Constitution would not defend the 1987 Constitution. It would weaken the continuity of Philippine law itself.
Constitutional Sedevacantism and Political Theology
One should also not be surprised if some of those eager to derail the present order are, in effect, constitutional or political sedevacantists.
The diehard Marcos loyalist may treat the 1987 Constitution as anathema, as though the post-EDSA Republic were an empty chair falsely occupied. Some Duterte partisans, in turn, may treat the present Marcos presidency as a kind of antipope regime: formally seated, but politically illegitimate in their eyes.
In both cases, the disease is the same: refusal to accept constitutional continuity unless one’s own faction occupies the throne.
That is not law. That is political theology dressed up as constitutional argument.
It turns constitutional debate into a contest of rival churches. Each faction has its own pope, antipope, saints, heretics, and excommunications. The Marcos loyalist of a diehard kind may reject the post-1987 order. The Duterte partisan may reject the present dispensation out of Dutertist setimentality. The liberal legalist may defend jurisprudence when it helps and dismiss it when it hurts. The result is a republic of selective obedience.
No serious legal order can survive that. As business leaders, professionals, workers, investors, civil servants, and ordinary citizens should all be concerned. Institutional continuity is not a luxury for lawyers. It is the basis of predictability. When precedent can be discarded because it is old, when rules are read only through factional advantage, and when quorum becomes either a weapon of obstruction or a tool of ambush, the cost is not only political embarrassment. The cost is institutional risk.
Of Both Warring Blocs and the Old Avelino Question
A sober observer need not romanticize either side. One may be against the system in general and still insist that the legal issue be treated seriously. Indeed, public distrust makes legal discipline more necessary, not less.
There is no need to pretend that either bloc represents constitutional purity. Both sides may speak of principle while pursuing power. Committee control, impeachment rules, leadership succession, investigations, and political survival are not minor matters. They are the substance of power.
The country has seen this performance too many times: senators invoking solemn duty while counting votes; guardians of democracy discovering principle when they lose the gavel; defenders of rules treating rules as sacred only when rules are useful to them.
Both blocs may be goddamned, as the frustrated citizen might say. One may even be tempted toward a Bonapartist impatience: if the chamber cannot govern itself, why not sweep the circus aside? That temptation is dangerous, but it is understandable. It is what democratic exhaustion sounds like when parliamentary language becomes perfume over decay.
To the sentimental, one misses figures like Miriam Defensor Santiago, Lorenzo Tañada, Jose W. Diokno, Laurel, and Tolentino. They had their contradictions, ambitions, vanities, and political sins, but they understood the weight of constitutional words. They could meet a legal controversy not merely with press releases, but with intellect, memory, and combat.
Today, too much of the discourse sounds like factional messaging pretending to be statesmanship.
Or perhaps the solons are scared of the surname Avelino itself. Jose Avelino left Philippine politics with one of its most infamous confessions: “What are we in power for?” That line survived because it was brutally candid. It stripped politics of incense. It told the public what many politicians thought but dared not say.
Good crooks and bad crooks, as the bitter formulation goes, may now accuse each other of violating principle. But the deeper suspicion remains: principle is being invoked because power is at stake.
And so the old question returns: What are they in power for? To convene? To legislate? To try impeachment? To investigate corruption? To protect allies? To delay accountability? To control committees? To avoid unfavorable votes? To prevent a rival from presiding? To use absence as leverage?
The public may not know every technical distinction between quorum and majority vote of all members, but it knows when procedure is being used as camouflage.
The Correct Legal Fight
The serious debate should not be whether Avelino is old. It is old, but old does not mean dead. The serious debate is whether the facts of the current Senate impasse are comparable to Avelino.
Those defending the twelve-senator action must show that the situation was extraordinary. They must show that the Senate faced more than ordinary absence. They must show that the chamber’s ability to function was being frustrated by strategic non-attendance, incapacity, impossibility, or circumstances beyond ordinary compulsion. They must show that the action restored institutional operation rather than merely transferred power from one faction to another.
Those opposing the action must do more than repeat that twenty-four requires thirteen. They must explain why Avelino does not apply. They must show that the absences were not legally comparable. They must show that the Senate Rules on election of officers require a stricter threshold. They must show that the denominator cannot be reduced under the circumstances.
Those are legitimate arguments. But no one should say “regardless of jurisprudence.” That phrase is constitutional illiteracy dressed as legal toughness.
Jurisprudence is not an accessory to the Constitution. It is the Constitution as interpreted by the Supreme Court. A senator, lawyer, professor, or commentator may distinguish a precedent. He may criticize it. He may ask the Court to abandon it. But he cannot honestly pretend it does not exist simply because it complicates his preferred arithmetic.
The Constitution does not speak in a vacuum. The Court gives meaning to its words. To disregard jurisprudence when it becomes inconvenient is not fidelity to the Constitution. It is factional convenience dressed as legal purity.
Why Absence Cannot Become Sovereignty
The danger in the anti-twelve position is obvious. If a bloc can defeat quorum by disappearance, boycott, calculated absence, or refusal to attend, then the Senate becomes hostage to those who refuse to work. The quorum rule, which exists to protect deliberation, becomes a veto power for obstruction.
A faction could simply stay away and paralyze the chamber until it gets its way. That cannot be the purpose of the Constitution.
The Senate is not a private clubhouse. It is a constitutional body. Its members are not elected to weaponize absence. They are elected to deliberate, vote, lose, win, and be accountable in public. If they disagree with a reorganization, they should appear and vote. If they believe the move is illegal, they should challenge it in the proper forum. But they should not be allowed to turn non-attendance into institutional blackmail.
This is where Avelino remains useful. It reminds the country that constitutional rules must preserve the functioning of government, not reward those who sabotage it.
But the danger on the other side is also real. If Avelino is applied carelessly, it can become a pretext for parliamentary raiding. A faction may manufacture urgency, declare reduced membership, and reorganize the Senate on a thinner number than the Rules ordinarily require. That would also be dangerous. Thus, the doctrine must therefore be applied narrowly. It is a shield against paralysis, not a sword for opportunism.
A View on Political Predictability
From a perspective of a concerned folk, the issue is not only who wins the Senate floor. The larger concern is predictability.
A functioning Senate matters to legislation, budgets, appointments, treaties, oversight, impeachment, procurement investigations, infrastructure policy, and national confidence. When the chamber cannot determine how it may legally convene, it sends a damaging signal: the political class may still treat institutions as temporary shelters for factional advantage.
The Masses watch that. Investors watch that. Civil servants watch that. Local governments watch that. Foreign partners watch that. Everyone watch that.
A country does not need perfect politics to function. But it needs basic institutional predictability. It needs rules that are not reinvented every time a bloc loses confidence in its numbers. It needs precedent that is not treated as disposable. It needs officials who understand that legal continuity is part of national stability.
When quorum becomes uncertain, governance becomes uncertain. When governance becomes uncertain, policy becomes uncertain. And when policy becomes uncertain, confidence erodes.
This is why the Senate quarrel should not be dismissed as mere political theater. Political theater can become institutional damage when it affects the operation of a constitutional body.
The Balanced Position
The proper position is neither romantic nor partisan. In a full and normally functioning twenty-four-member Senate, thirteen is the standard quorum. That should remain the default rule. The Senate Rules matter. The phrase “all members” cannot be casually diluted.
But Avelino v. Cuenco remains controlling jurisprudence in extraordinary circumstances where rigid arithmetic would reward obstruction and prevent the Senate from functioning. It should not be thrown away because it was decided under the 1935 Constitution. It should not be exaggerated into a license for twelve senators to do anything they wish. It should be read carefully and applied only where the facts justify it.
That is the serious constitutional position. If Avelino applies, it should be applied with precision. If it does not apply, it should be distinguished with care. But it should not be buried by slogan.
The Senate should not be governed by arithmetic alone. Neither should it be governed by ambush. It should be governed by law: the Constitution, the Rules, and the jurisprudence that gives both practical meaning.
The Chair and the Republic
The current dispute will eventually pass. One bloc will gain, another will complain, and the chamber will move on to the next contest. But the precedent set by this episode may last longer than the careers of those involved.
That is why the issue deserves seriousness. If senators wish to defend the Constitution, they must defend all of it: text, rules, jurisprudence, and continuity. They cannot defend only the paragraph that keeps their chair warm. They cannot invoke the Rules while ignoring precedent. They cannot invoke precedent while abusing the Rules.
The public has every reason to be skeptical. The old Avelino question still hangs over the chamber: what are we in power for?
If they are in power to legislate, they should convene. If they are in power to try impeachment, they should do so under rules that can withstand scrutiny. If they are in power to investigate corruption, they should investigate without fear or theatrical selectivity. If they are in power to defend the Senate, they should stop treating it as a hostage.
And if they are in power only to protect factions, then the people should at least be spared the sermon.
Avelino v. Cuenco should not be buried. It should not be worshipped either. It should be read, understood, and applied with care.
The Constitution changes. The legal order continues. Jurisprudence survives until lawfully overturned.
That is not nostalgia. Instead, that is institutional discipline.
