G.R. No. A.M. No. 15-05-136-RTC. December 4, 2018
Office of the Court Administrator, Complainant, vs. Rogelio M. Salazar, Jr., Sheriff IV, Regional Trial Court-Office of the Clerk of Court, Boac, Marinduque, Respondent.

FACTS

Respondent Rogelio M. Salazar, Jr., a Sheriff IV, was arrested for violations of Republic Act No. 9165 (The Comprehensive Dangerous Drugs Act of 2002) after a search of his residence. The drugs seized and the subsequent confirmatory drug test results, which were positive, formed the basis for both criminal cases and the instant administrative complaint for grave misconduct and conduct prejudicial to the best interest of the service. The Regional Trial Court (RTC) later dismissed the criminal cases, ruling that the search warrant was void and declaring the seized drugs and the confirmatory test results inadmissible in evidence under the constitutional exclusionary rule.
In this administrative proceeding, respondent moved for the dismissal of the charges against him. He argued that since the evidence obtained from the illegal search was declared inadmissible for the criminal cases by operation of the exclusionary rule under Section 3(2), Article III of the 1987 Constitution , the same evidence could not be used to support the administrative case against him. He contended that without this evidence, the administrative complaint had no leg to stand on.

ISSUE

Whether the constitutional exclusionary rule, which renders evidence obtained from an unreasonable search or seizure inadmissible, applies to administrative proceedings such that it bars the use of such evidence to establish administrative liability.

RULING

No. The exclusionary rule does not bar the use of illegally obtained evidence in administrative proceedings. The Separate Concurring Opinion clarified the scope of the exclusionary rule under the 1987 Constitution . While Section 3(2), Article III states that evidence obtained in violation of the right against unreasonable searches and seizures is inadmissible “for any purpose in any proceeding,” this constitutional guarantee must be interpreted in harmony with the State’s compelling interest in maintaining discipline and integrity within the public service, particularly the judiciary.
The legal logic is grounded on the fundamental distinction between criminal and administrative cases. Administrative proceedings are independent from criminal actions; they require only substantial evidence, not proof beyond reasonable doubt, and aim to determine fitness to remain in office, not criminal culpability. Applying the exclusionary rule rigidly to administrative cases would undermine the government’s ability to discipline its own personnel, especially for offenses as grave as drug use, which erodes public trust in the judiciary. The constitutional intent is to deter law enforcement misconduct in criminal investigations, not to shield erring public officers from administrative accountability. Therefore, the evidence from the void search, including the confirmatory drug test result, remains admissible for the purpose of the administrative case. Respondent’s admission of drug use, supported by this evidence, warranted his dismissal from service for grave misconduct.
