Case Digest (G.R. No. 72670)
Expanded Legal Reasoning Model

Facts:

  • Background of the Aquino Assassination
    • On August 21, 1983, former Senator Benigno “Ninoy” Aquino, Jr. was fatally shot at Manila International Airport under military escort.
    • The military’s initial version blamed a lone communist-hired gunman, Rolando Galman, who was immediately killed by soldiers.
  • Agrava Board Investigation and Reports
    • President Marcos appointed the Fact-Finding Board (Agrava Board) on October 22, 1983.
    • After 125 hearing days and 194 witnesses, the Board issued:
      • A four–member majority report finding a military conspiracy and recommending indictment of all 26 military respondents.
      • A minority report by the chairman narrowing culpability to six military conspirators.
    • Marcos publicly rejected the Board’s findings, insisted on the original military version, and referred the minority report for prosecution in the Sandiganbayan.
  • Tanodbayan/Sandiganbayan Proceedings and Commission Inquiry
    • In January 1985, the Tanodbayan filed Informations in the Sandiganbayan charging 26 military and civilian respondents.
    • Petitioners (Galman family, retired Justices, academics) sought certiorari/prohibition alleging serious irregularities:
      • Executive interference (“moro-moro”) via a secret Malacañang conference ordering a pre-scripted acquittal.
      • Suppression and harassment of prosecution evidence and witnesses.
      • Bias of Sandiganbayan justices and partiality of prosecutors.
    • A Supreme Court–appointed three-member Commission (Vasquez, German, Caguioa) held hearings (June 16–July 16, 1986), found credible proof of Presidential pressure on both court and prosecutors, and recommended a mistrial.

Issues:

  • Did executive interference and collusion vitiate the Sandiganbayan trial and strip it of due process and jurisdiction?
  • Were vital prosecution evidence and witnesses suppressed or harassed, undermining a fair opportunity to prosecute?
  • Is the resulting acquittal judgment null and void ab initio, and does double jeopardy bar a retrial?
  • Are petitioners entitled to injunctive relief and a declaration of mistrial?
