Attachment of Jeopardy
Jeopardy attaches when the accused is formally arraigned before a court of competent jurisdiction and enters a plea, thereby facing the risk of conviction and punishment . Mere filing of charges or issuance of a warrant does not suffice.
Valid Termination
Double jeopardy bars retrial only if the initial proceeding terminated on the merits: conviction, acquittal, or dismissal for lack of merit. Conversely, dismissals without prejudice—e.g., for procedural irregularities or denial of a speedy trial—do not trigger the bar .
Same Offense / Same Act
Philippine courts adopt the “same evidence” test: if the subsequent prosecution requires proof of materially different elements or distinct acts, it is considered a separate offense. Conversely, prosecution under a statute and a local ordinance for the same act may also trigger double jeopardy .

Exceptions Where Double Jeopardy Does Not Apply
The Supreme Court recognizes key exceptions, notably where the State is deprived of due process (e.g., sham trial, capricious dismissal), when a mistrial is declared, or when the accused appeals (thereby waiving the right) .

Landmark Cases
1. People v. Laguio (2007)
Though somewhat older, this leading decision addressed sham acquittal on appeal. The Court held that when an appellate court acquits the accused by blindly parroting defense testimony and entirely neglecting prosecution evidence, there is a denial of due process. Consequently, the acquittal is void for double jeopardy purposes, and the State may seek certiorari under Rule 65 .
Doctrine: A sham trial or mock acquittal does not constitute a valid termination; therefore, double jeopardy does not attach.
Rationale: Safeguard against procedural abuse that undermines the integrity of judicial proceedings.
2. People v. Alejandro (GR 223099, 2018)
Reinforcing Laguio, the Court ruled that dismissal of an information motivated by mere absence of congestion at trial—without evaluating the merits—is capricious and constitutes grave abuse of discretion, thereby negating double jeopardy protection .
Doctrine: Capricious, meritless dismissal is no final judgment; retrial is permissible.
Rationale: Ensures that acquittals arise from substantive adjudication, not arbitrary court action.
3. People v. Carmelo (e.g., Carmelo vs. People, GR L‑3580, 1950)
Although historic, this en banc ruling remains doctrinally significant. The Court abrogated earlier doctrine (Tarok) and held that once an accused pleads and is arraigned, even if a graver offense arises from the same act discovered later, the accused may be charged under an amended information, crediting prior sentence .
Doctrine: A supervening-offense arising from the same act is not barred by double jeopardy if timely amended.
Rationale: Prevents technical procedural obstacles from preventing just punishment for more serious crimes.

Legal Doctrine Summarized
The Philippine doctrine on double jeopardy upholds critical guarantees while recognizing practical exceptions:
Attachment and finality are prerequisites.
Final judgment must be genuine and on the merits.
Same offense or act—whether statutory or by ordinance.
Exceptions (due process breach, mistrial, appeal) allow retrial.
The supervening offense rule allows the State to prosecute for a graver charge stemming from the same act—if discovered during the ongoing case—without violating the constitutional bar .

Contemporary Significance
Philippine jurisprudence continues to reinforce these principles, ensuring both state and individual rights are balanced. In cases involving sham proceedings or capricious terminations, courts permit retrial. The allowance for amended charges promotes justice without compromising constitutional safeguards.
