The Janki Method: Beating Goliaths With Their Own Rulebook

Melinda Janki, a Guyanese lawyer, has filed ten cases against ExxonMobil and won repeatedly against one of the largest oil companies in the world, starting alone with a pensioner client. Her method inverts the usual David-vs-Goliath approach: instead of asking judges to invent new protections, make new law, or accept moral arguments, she finds rules that already exist on the books and forces the opponent to comply with them. Her 2020 win came from page 191 of a 197-page rulebook — a clause limiting environmental permits to five years that nobody had bothered to enforce. Her 2025 Scope 3 emissions win used a clause she had earlier helped draft into law that required environmental impact assessments to include indirect impacts. The framework rests on a sharp separation: heart decides what to fight for, head decides how to fight. Powerful incumbents accumulate rule debt — regulations, treaties, license conditions, and procedural requirements they assume nobody will enforce. The method exploits that debt. It is slow, technical, and unglamorous, but it converts the opponent's own infrastructure into the weapon. Each win compounds: precedents bind future cases, costs rules protect future plaintiffs, and parent-company guarantees expose the real balance sheet. The opponent cannot dismiss enforcement of their own agreements as activism.
