This is a revision of WP 84-4. The authors develop an explicit theoretical foundation for the common belief that legitimation is somehow important in mobilizing collective action. They distinguish validity of a rule (collective support) from propriety (individual support) and predict that validity affects mobilization independent of propriety. Results of an experimental test support the derivations.
