Conspiracy and Proposal as Sources of Criminal Liability
Article 8 of the Revised Penal Code supplies the controlling rule: conspiracy and proposal to commit a felony are punishable only when the law specially provides a penalty. The same provision defines conspiracy as an agreement by two or more persons concerning the commission of a felony coupled with a decision to commit it, and proposal as the act of a person who has decided to commit a felony and proposes its execution to another person or persons.
These concepts have two distinct uses. First, conspiracy may operate as a mode of incurring liability for a felony that is attempted, frustrated, or consummated, because the criminal act of one conspirator is legally attributed to the others. Second, conspiracy and proposal may themselves be punishable preparatory offenses, but only when a statute expressly punishes them even though the target felony has not yet begun.
The law does not punish bare criminal thought, loose discussion, or association with wrongdoers. Liability begins only when the agreement, decision, proposal, or participation has the degree of firmness required by law and is connected to a felony or to a statute that specially penalizes the preparatory act.
Conspiracy as a Mode of Incurring Criminal Liability
Conspiracy as a mode of liability is a rule of attribution. Once a conspiratorial design is proved, the prosecution need not show that each conspirator personally performed every element of the felony, because each one who knowingly joined the common design becomes responsible for acts done by the others in furtherance of that design.
The decisive question is whether the accused consciously adopted the criminal purpose before or during execution. The inquiry is not limited to the hand that fired the shot, inflicted the wound, took the property, opened the door, or restrained the victim; it includes the planner, lookout, blocker, armed companion, driver, signaler, and other participant whose conduct shows unity of purpose and intent.
Requisites of Conspiracy as Mode
- Plurality of persons. At least two persons must share the criminal design, although one may conspire with unidentified, uncharged, acquitted, or still at large participants if the evidence independently proves the agreement.
- Common criminal objective. The participants must be united in the commission of a definite felony, not merely connected by friendship, kinship, employment, political affiliation, or presence at the same place.
- Agreement and decision. There must be a meeting of minds and a resolve to commit the felony; tentative talk, bravado, speculation, or passive knowledge does not suffice.
- Participation referable to the plan. Each accused must perform an act, give encouragement, supply means, provide moral support, guard, facilitate escape, prevent resistance, or otherwise cooperate in a way that reveals adoption of the common design.
- Proof beyond reasonable doubt. Conspiracy is never presumed from the mere fact that several persons are charged with or present at the crime; the prosecution must establish it with the same moral certainty required for the felony itself.
Express and Implied Conspiracy
Conspiracy may be express, as when the participants directly plan the offense, assign roles, and agree on the manner of execution. More often it is implied from coordinated conduct before, during, and immediately after the crime.
No formal agreement, written plan, spoken command, or long preparation is indispensable. A conspiracy may arise on the spot when the offenders act with such coordinated purpose that their conduct shows a spontaneous meeting of minds.
Acts before the offense may show planning, surveillance, procurement of weapons, recruitment, or role assignment. Acts during the offense may show simultaneous attack, blocking of escape, intimidation of bystanders, guarding, signaling, or pursuit of the victim. Acts after the offense may corroborate the prior design when they involve coordinated flight, concealment of weapons, division of proceeds, suppression of evidence, or protection of co-conspirators.
Post-crime conduct cannot by itself make a stranger a conspirator in an already completed offense. If the person had no prior or contemporaneous participation, liability may instead be as an accessory or for a separate offense, depending on the facts and the applicable law.
Conduct Insufficient by Itself
Mere presence at the scene does not prove conspiracy, but presence becomes incriminating when it is intended to encourage, intimidate, keep watch, prevent aid, block escape, or otherwise support the execution. Mere companionship with the principal offender is likewise insufficient unless the surrounding acts show shared purpose.
Mere knowledge of another person's criminal intent, silence, failure to object, failure to prevent the crime, relationship with the offender, flight from the scene, or approval after the fact does not establish conspiracy without acts showing conscious participation. The law requires intentional cooperation, not accidental proximity or moral indifference.
Simultaneous action is strong evidence only when the acts are complementary and directed toward the same criminal result. Several persons may separately commit similar acts without conspiracy if each acts from an independent impulse and without a shared design.
Effect of Established Conspiracy
When conspiracy is established, the act of one is the act of all. Each conspirator is treated as a principal for the felony committed in furtherance of the conspiracy, even if his visible act would appear minor when viewed in isolation.
The doctrine rests on collective intent. A conspirator adopts the execution of the criminal plan and assumes responsibility for acts that are necessary, incidental, or naturally and logically connected with that plan.
The effect is strongest where the planned offense requires division of labor. In a coordinated killing, it is immaterial who delivered the fatal blow if all shared the intent to kill and acted to ensure the killing. In a robbery, it is immaterial who physically took the property if the others guarded, threatened, drove, or prevented resistance pursuant to the plan.
Conspiracy does not erase the need to prove identity. The prosecution must still show that the particular accused was one of those who joined the criminal design; collective liability cannot be used to fill a gap in proof that the accused was present, connected, or participating.
Scope of Collective Liability
- Acts within the plan. A conspirator is liable for acts committed by another conspirator in carrying out the common objective.
- Natural and logical consequences. A conspirator may be liable for a resulting offense that flows from the agreed criminal design, even if he did not personally desire the precise manner by which the result occurred.
- Acts foreign to the plan. A conspirator is not liable for an independent act of a co-conspirator that springs from a private motive and is outside the common design.
- Qualifying and aggravating circumstances. Circumstances arising from the manner of execution bind those who knew, adopted, or could be fairly charged with that method as part of the plan; purely personal circumstances affect only the person to whom they attach.
- Personal defenses and mitigation. Exempting, justifying, mitigating, or aggravating matters personal to one accused do not automatically benefit or burden all unless the law or the facts make them common.
A conspirator who joins only after the felony has been completed cannot be liable for that felony by conspiracy. Assistance after completion may create accessory liability or another punishable act, unless the assistance was previously agreed upon and formed part of the execution or escape plan.
A claim of withdrawal matters only when it is clear, voluntary, made before execution, and shown by acts inconsistent with the criminal design. A secret change of mind, a late refusal after the crime has begun, or abandonment after one's prior assistance has already facilitated the offense does not automatically erase liability.
Conspiracy is generally incompatible with culpable felonies based on negligence because conspiracy requires intentional agreement to commit a felony. Several negligent actors may be liable for their own imprudence, but their liability does not rest on a shared criminal intent to commit a negligent offense.
Conspiracy as a Separately Punishable Preparatory Offense
When the target felony has not been attempted, frustrated, or consummated, conspiracy is not punishable under the Revised Penal Code unless a provision specially penalizes it. In that setting, the crime punished is the agreement and decision to commit the specified felony, not the completed target felony.
The RPC specially punishes conspiracy and proposal to commit treason, conspiracy and proposal to commit coup d'etat, rebellion, or insurrection, and conspiracy to commit sedition. Special penal laws may also punish conspiratorial preparation, such as the separate offense of conspiracy to commit terrorism under the Anti-Terrorism Act.
For a punishable conspiracy, no overt act toward actual execution of the target felony is ordinarily required unless the particular statute demands one. The agreement and decision are the punishable social danger because the law treats the joint resolution as sufficiently proximate to the protected interest.
If the conspirators proceed to execute the target felony, liability ordinarily shifts to the felony actually attempted, frustrated, or consummated. The preparatory conspiracy should not be used to duplicate punishment for the same criminal design unless the governing statute clearly creates separate punishable interests.
Proposal and Its Limited Effect
Proposal is unilateral. It exists when a person has already decided to commit a felony and communicates to another person a proposal to execute it.
Proposal does not ordinarily make the proposer liable for the felony proposed, and it does not make the recipient liable for merely hearing, rejecting, or failing to report the proposal. Criminal liability arises only when the law specially punishes the proposal or when the proposal ripens into conspiracy or actual participation.
Requisites of Punishable Proposal
- Firm decision by the proposer. The proposer must have resolved to commit a definite felony; a hypothetical statement, wish, threat, joke, political rant, or abstract approval of criminal conduct is insufficient.
- Communication to another. The proposal must be conveyed to a determinate person or persons whose participation in execution is sought.
- Proposal to execute the felony. The communication must invite or urge participation in the execution, not merely discuss legality, possibility, grievance, or motive.
- Special statutory penalty. The law must expressly punish proposal to commit the particular felony, such as proposal to commit treason, coup d'etat, rebellion, insurrection, or terrorism.
Proposal is complete, where specially punished, upon the serious communication of the criminal plan by one who has decided to commit the felony. Later abandonment may be relevant to intent or credibility, but it does not automatically undo a completed punishable proposal.
If the person to whom the proposal is made accepts and both decide to commit the felony, the situation becomes conspiracy. If the planned felony is later attempted or consummated, liability is determined by the executed felony and by each person's participation in the common design.
Proposal differs from public incitement. Proposal is directed to particular persons whose participation is sought in execution, while incitement under specific penal provisions commonly involves public words, writings, or acts that encourage others to commit a punishable offense without requiring a private agreement.
Comparison of Legal Effects
| Concept | Essential Act | When Liability Arises | Effect |
|---|---|---|---|
| Conspiracy as mode of liability | Agreement, decision, and participation in a felony attempted, frustrated, or consummated | When the accused knowingly joins the common design and the felony is carried out within its scope | Each conspirator is treated as principal for acts done in furtherance of the plan |
| Conspiracy as preparatory offense | Agreement and decision to commit a felony specially punished by law | Even before the target felony begins, if the statute expressly penalizes the conspiracy | The agreement itself is punished as a separate offense |
| Proposal | A decided offender proposes execution of a felony to another person | Only when the law specially punishes proposal, or when acceptance produces conspiracy | The proposer may be liable for the proposal; the recipient is not liable merely for hearing or rejecting it |
| Mere knowledge or presence | Awareness of a plan or physical proximity to the offense | No liability by itself | It becomes relevant only when joined with acts showing intentional cooperation or another basis of liability |
Relation to Other Forms of Participation
Conspiracy differs from direct physical execution because a conspirator may be liable even when he did not personally perform the act that immediately produced the criminal result. The basis is his intentional adoption of the plan and contribution to its success.
Conspiracy differs from accomplice liability because an accomplice knowingly aids the crime without becoming part of the common criminal resolution as a principal. The line depends on whether the accused shared the criminal design itself or merely cooperated in a secondary manner.
Conspiracy differs from accessory liability because an accessory generally acts after the crime has been committed. Prior agreement to receive the offender, conceal the weapon, dispose of proceeds, or facilitate escape may show conspiracy if it was part of the original execution plan; absent such prior agreement, post-crime assistance is not proof of authorship of the completed felony.
Conspiracy also differs from inducement. A principal by inducement intentionally causes another to commit the crime through command, price, reward, or powerful influence, while a conspirator joins a common plan. The same facts may sometimes show both inducement and conspiracy, but liability must still rest on proven participation and intent.
Pleading, Proof, and Judgment
Because conspiracy changes the attribution of acts, the accusation should inform the accused that conspiracy is relied upon or state facts that fairly show a common design. The accused must be able to meet the charge that another person's act will be imputed to him.
If conspiracy is not sufficiently alleged or proved, each accused is liable only for the acts personally committed and for the participation independently established. A weak conspiracy theory cannot convert doubtful presence into principal liability.
Acquittal of some alleged conspirators does not automatically acquit the remaining accused if the evidence proves that he conspired with other persons, including unidentified or untried persons. It is different when the judgment necessarily finds that no conspiracy existed or that the alleged criminal act itself was not committed.
Where conspiracy is proved, the judgment should connect the accused to the shared design and identify the acts or circumstances showing his participation. The conclusion that the act of one is the act of all follows only after the common design has been established by competent evidence.
Doctrinal Synthesis
Conspiracy as a mode of incurring criminal liability is not a separate felony but a rule that makes several offenders collectively responsible for the felony they intentionally agreed to commit. Its force lies in shared intent, coordinated action, and the attribution of acts done in furtherance of the common plan.
Proposal is narrower because it is a one-sided preparatory act. It creates criminal liability only when the law expressly punishes the proposal, and it becomes conspiracy only when the person addressed accepts and joins the decision to commit the felony.
The controlling limits are strict: no punishment for mere thought, no conspiracy by presumption, no collective liability without proof of common design, no responsibility for acts foreign to the plan, and no punishable proposal or preparatory conspiracy unless the law specially says so.
