Brazil's STJ suspends fracking ruling, delaying oil and gas exploration decision

Brazil's Superior Tribunal de Justiça (STJ) suspended its judgment on whether hydraulic fracturing (fracking) can be used for unconventional oil and gas exploration, and under what conditions. The case involves major energy companies, the national petroleum agency (ANP), and the federal prosecutor's office (MPF). The suspension delays a definitive legal framework, creating regulatory uncertainty for the sector.
