Hannibal, Donna, Florence and Joel, concerned residents of Laguna de Bay, filed a complaint for mandamus against the Laguna Lake Development Authority, the Department of Environment and Natural Resources, the Department of Public Work and Highways, Department of Interior and Local Government, Department of Agriculture, Department of Budget, and Philippine National Police before the R TC of Laguna alleging that the continued neglect of defendants in performing their duties has resulted in serious deterioration of the water quality of the lake and the degradation of the marine life in the lake. The plaintiffs prayed that said government agencies be ordered to clean up Laguna de Bay and restore its water quality to Class C waters as prescribed by Presidential Decree No. 1152, otherwise known as the Philippine Environment Code. Defendants raise the defense that the cleanup of the lake is not a ministerial function and they cannot be compelled by mandamus to perform the same. The RTC of Laguna rendered a decision declaring that it is the duty of the agencies to clean up Laguna de Bay and issued a permanent writ of mandamus ordering said agencies to perform their duties prescribed by law relating to the cleanup of Laguna de Bay.

1. Environmental Mandamus Requisites
Under Rule 65 of the Rules of Court and the Rules of Procedure for Environmental Cases (A.M. No. 09-6-8-SC), a writ of mandamus lies to compel a public officer or government agency to perform a duty specifically enjoined by law. While administrative agencies generally exercise discretion regarding the precise operational details of execution, the overarching legal mandate to enforce statutory obligations, protect public health, and clean up degraded bodies of water constitutes a compellable ministerial duty when agencies fail or refuse to act.
2. Continuing Mandamus Nature
A writ of continuing mandamus is a special environmental remedy issued by a court when a government agency fails to perform an act enjoined by law as a duty. Unlike an ordinary writ of mandamus that terminates upon judgment, a continuing mandamus directs respondent agencies to perform a series of acts decreed by final judgment and requires them to submit periodic compliance reports under court supervision until the judgment is fully satisfied.
3. Ministerial Duty Scope
The cleanup and rehabilitation of public waters prescribed under environmental protection statutes like Presidential Decree No. 1152 are mandatory statutory obligations. Although government agencies retain administrative choice regarding the choice of means, equipment, or allocation of personnel, the core requirement to execute environmental protection mandates is non-discretionary. Consequently, courts possess full judicial authority to issue writs of mandamus to enforce these statutory duties against recalcitrant executive agencies.
