In response to escalating environmental violations within its borders, the Province of Silangan enacts Ordinance No. 2026-12, requiring all industrial facilities operating within the province to obtain an Environmental Compliance Permit (ECP) from the Provincial Environment and Natural Resources Office (PENRO) before commencing operations or continuing existing operations. The Environmental Management Bureau (EMB) of the Department of Environment and Natural Resources (DENR) asserts exclusive nationwide authority to issue environmental permits and to regulate compliance under the Clean Air Act (Republic Act No. 8749) and the Clean Water Act (Republic Act No. 9275), and has not yet acted on any permit applications or issued implementing guidelines for the ordinance. GreenTech Industrial, Inc. files a petition for certiorari with the Regional Trial Court to annul Ordinance No. 2026-12 on ultra vires grounds.
