G.R. No. 81567 - Umil vs. Ramos

On February 1, 1988, RIOU–CAPCOM received a tip that “Ronnie Javelon,” wounded in a QC hospital, was actually Rolando Dural of the NPA liquidation squad responsible for the January 31 killing of two CAPCOM soldiers in Caloocan.
Dural was transferred for security, then on February 4 positively identified by eyewitnesses as the gunman. The Caloocan fiscal conducted an inquest and filed an information for Double Murder with Assault upon Agents of Authority (Crim. Case No. C-30112), later adding Bernardo Itucal Jr.; no bail was recommended.
On February 6 a habeas corpus petition was filed for Roberto Umil, Rolando Dural and Renato Villanueva; Umil and Villanueva posted bail (Feb 26) in Pasay, rendering their petitions moot.
Dural remained detained, was tried and on August 17, 1988 found guilty and sentenced; he is now serving sentence and the writ no longer lies.

June 27, 1988: Surrendered NPA member Ramos identified NUFC leaders and a Marikina safehouse used by Renato Constantino.
August 12, 1988: Pursuant to a search warrant, PC agents seized from Constantino’s house an M16 rifle, pistol, grenades, ammunition, radio equipment and voluminous subversive documents; Constantino was arrested.
Same day: Wilfredo Buenaobra arrived, admitted being an NPA courier, and letters addressed to Constantino were seized.
August 13, 1988: Agents, guided by leads, searched Amelia Roque’s Caloocan residence, seizing more subversive documents, ammunition and a grenade; Roque arrested.
Inquests conducted; Roque was charged under PD 1866 and the Anti-Subversion Act (RTC Caloocan C-1196; MTC Caloocan C-150458), bail set; Buenaobra charged (MTC Marikina No. 23715), bail set ₱4,000.
August 24, 1988: Habeas corpus petition filed for Roque and Buenaobra. Buenaobra waived relief and remained detained; only Roque’s petition proceeded.

August 13, 1988: Anonuevo and Casiple arrived at Constantino’s Marikina house under surveillance; frisk uncovered two pistols, magazines, live ammunition and subversive documents; no firearms licenses.
August 15, 1988: After inquest, Psig. Anonuevo (Crim. Case No. 74386) and Casiple (No. 74387) were charged under PD 1866 before RTC Pasig; no bail recommended.
August 24, 1988: Habeas corpus petition filed; petitioners claimed illegal arrest without warrant and void informations for lack of preliminary investigation; they refused to sign PI waiver required by Rule 112, Sec. 7.

May 12, 1988: PC agents with a search warrant raided a suspected CPP–NPA house in Marikina and found subversive documents and live .45-cal ammunition in Vicky Ocaya’s car. Danny Rivera, her companion, was released.
Ocaya could not produce a firearms permit; an information under PD 1866 (Crim. Case No. 73447, RTC Pasig) was filed.
May 17, 1988: Habeas corpus petition filed for Ocaya and Rivera; Rivera released; Ocaya claimed illegal arrest and denial of PI.

Petitioners across cases alleged that firearms, ammunition and subversive documents were “planted”; no evidence supported this.
Military surveillance and in-depth investigation based on credible leads from surrendered rebels accounted for lawful searches and seizures.

November 22–23, 1988: Deogracias Espiritu, PISTON secretary-general, was accused of inciting nationwide strike and sedition by speeches at the National Press Club and in Sta. Mesa.
November 23, 1988: He was arrested at home without a warrant and brought to Police Station No. 8; an information for Inciting to Sedition (Art. 142, RPC; Crim. Case No. 88-683-85, RTC Manila) was filed.
Bail set at ₱60,000.

December 14, 1988: Romulo Bunye II was killed in Alabang; on December 28, Ramil Regala was arrested and implicated Nazareno.
Nazareno was arrested without warrant, brought to police HQ; January 3, an information for murder was filed (Crim. Case No. 731, RTC Makati).
January 10, 1989: RTC denied his motion for bail; January 13, 1989: habeas corpus petition filed; January 30 hearing before RTC Biñan; petition denied on February 1, 1989.

All eight petitions consolidated due to common issues on warrantless arrest and void informations.
Except where moot (Umil, Villanueva, Buenaobra) or where bail was reduced (Espiritu), petitions denied; no irregularity in arrests, detentions or process.

Were the warrantless arrests lawful under Rule 113, Section 5 (a)–(c)?
Were the informations filed valid notwithstanding the absence of a preliminary investigation (Rule 112, Section 7)?
Does the filing of a valid information and issuance of process before a competent court bar relief by habeas corpus (Rule 102, Section 4)?
Are any petitions rendered moot or academic by subsequent release on bail or by conviction?
Do unsubstantiated claims of planted evidence or illegal searches justify a writ of habeas corpus?
