Chamber of Commerce v. City of Seattle

U.S. District Court for the Western District of Washington
Resolved without decision
April 10, 2020

U.S. Chamber and co-plaintiff dismiss without prejudice remaining antitrust claims against City of Seattle’s unionization ordinance for independent contractors.  Through its litigation, the U.S. Chamber blocked implementation of this ordinance for more than four years (it has never been implemented).  As a result of the U.S. Chamber’s antitrust claims, in 2019 the City also was forced to remove driver pay as a subject for permissible collective bargaining.  The City of Seattle has now enacted a new ordinance, which does not alter the status of drivers but which seeks to develop a different regulatory scheme regarding driver pay.  Because the City no longer plans to move forward with its old unionization ordinance and instead plans to implement this new ordinance, there is no longer a need to continue this litigation.  Accordingly, the U.S. Chamber and its co-plaintiff have voluntarily dismissed the remaining claims, but without prejudice to reviving the suit in the future if the City ever did reanimate its effort to unionize independent contractors.
