Briefings

Philippine lawyer Rose Liza Eisma-Osorio led a legal campaign in 2007 to halt oil exploration in the Tañon Strait by petitioning the Philippine Supreme Court. The court ruled in April 2015 to void the contract allowing Japanese energy company JAPEX to drill, protecting 14 whale and dolphin species and coral reefs. Eisma-Osorio now leads the campaign as senior director of Oceana Philippines.
