What is the test for "more effective relief" in a personal injury case?

^11. Holden v. Arnebergh, supra, 265 Cal.App.2d at pages 91-92, did not impose a requirement of "more effective" relief; it applied the principle that "the court does not abuse its discretion in refusing to entertain [a declaratory relief] action where otherwise plaintiff has a speedy and adequate remedy."
