MINNEAPOLIS, Minn. (From news reports) -- Cities suing Kimberly-Clark Corp over damage to their sewer systems from toilet wipes they say were falsely advertised as "flushable" will gain access to previously withheld internal company documents, a judge decided on Thursday.

U.S. Magistrate Judge Tony Leung in Minneapolis said attorney-client and work-product privileges did not apply to documents considered by David Powling, the company's research and engineering technical leader, in concluding wipes were not capable of clogging waste water treatment facilities.
