G.R. No. 73218 , June 20, 1986
Irenea San Diego-Lorenzo, petitioner, vs. Major Eustaquio Mallillin, Captain Rolando Lorenzo, and Segundo Lorenzo, respondents.

FACTS

Petitioner Irenea San Diego-Lorenzo filed a habeas corpus petition alleging that her husband, Mariano Lorenzo, was detained by the respondents. She claimed that on December 9, 1985, Mariano went to the 171st PC Company headquarters in Malolos, Bulacan, upon the invitation of respondent Major Eustaquio Mallillin for an arbitration conference concerning a land dispute with Segundo Lorenzo, father of respondent Captain Rolando Lorenzo. Mariano failed to return home thereafter. The Supreme Court issued the writ, designating the Regional Trial Court (RTC) of Bulacan to hear the case.
The respondents, through returns and a supplemental return attested by the PC Provincial Commander, denied having Mariano in their custody, asserting the detention claim was false. They submitted an affidavit from court personnel who claimed to have seen Mariano at the RTC premises around December 18 or 19, 1985. The RTC, after hearing, found petitioner’s evidence circumstantial. It established that Mariano was indeed invited to the PC headquarters on December 9, was last seen by his wife going there, and remained missing despite her complaints to authorities. However, the court concluded the evidence did not clearly substantiate that respondents were currently detaining him.

ISSUE

Whether the writ of habeas corpus should be granted to produce Mariano Lorenzo, given the conflicting accounts and the nature of the evidence presented regarding his disappearance and alleged detention.

RULING

The Supreme Court dismissed the petition. The legal logic hinges on the specific purpose and requisite proof for a writ of habeas corpus. The writ is a remedy designed to inquire into the legality of a person’s detention and to secure immediate release if the detention is unlawful. Its efficacy depends on the ability of the court to compel the production of the detained person before it. In this case, the RTC’s factual findings, which the Supreme Court relied upon, indicated that the evidence failed to definitively establish that Mariano Lorenzo was under the custody or restraint of the respondents at the time of the proceedings.
The Court acknowledged the strange and puzzling circumstances of the disappearance, which occurred incidental to the military’s involvement in a private land dispute. However, habeas corpus cannot be used solely as a tool for investigation into a disappearance where custody by the respondents is not sufficiently proven. Since the courts were “in no position” to resolve whether the respondents were detaining Mariano or had knowledge of his whereabouts based on the available record, the petition could not be sustained. The dismissal was without prejudice to future actions if new facts emerge. The Court directed the AFP Chief of Staff to conduct an investigation and suggested the petitioner may bring the matter to the Presidential Commission on Human Rights, recognizing the gravity of the disappearance while adhering to the procedural limits of the habeas corpus remedy.
