Scenario. A large platform, incorporated in one country, operating primarily from a second, with most of its users in a third, has for years run a help-each-other-with-work feature that its founding materials committed to "restoring dignity to day labor." Over the last three years, the platform has quietly shifted the feature into a piecework marketplace with a take-rate its own founding documents would have flagged. Complaints to each jurisdiction's regulators have been passed around and dropped; no one court has reach, and no one government wants to go first. A group of workers' cooperatives from six countries wants to bring a single claim — in a forum none of them has access to. They need one to exist.

Challenge: Design a cross-border adjudication forum that hears claims that transnational institutions have drifted from the mandates under which they hold public commitments, in cases where no single jurisdiction has sufficient leverage. Produce the forum's design: its basis of jurisdiction, the remedies it can order, its limiting doctrines, and the safeguards that keep it independent.

Evaluation. A strong proposal gives the forum real bite on multinationals that escape any single jurisdiction while staying independent of both geopolitical blocs and the defendants it hears, and avoiding the capture that has dogged investment arbitration.
