WASHINGTON, D.C. - The U.S. Supreme Court on March 24 invited the U.S. solicitor general to file a brief expressing the views of the United States on whether to grant review of a Ninth Circuit U.S. Court of Appeals opinion that ruled that revenue sharing between mutual funds and a 401(k) plan's administrative service provider did not violate the plan or the Employee Retirement Income Security Act (Glenn Tibble, et al. v. Edison International, et al., No. 13-550, U.S. Sup.).
