TOPEKA, Kan. (AP) -- Shawnee County District Attorney Chad Taylor has filed a complaint against members of the Kansas Corporation Commission over alleged violations of the state's open meetings act.

WIBW radio reports (http://bit.ly/1bWjt7L ) that Taylor filed the complaint Wednesday in Shawnee County District Court. It seeks an injunction against the KCC and its individual members over approval of a rate increase for a Salina water district.

Attorneys for the Citizens Utility Ratepayer Board argue that the KCC approved the rate increase improperly and asked Taylor and Attorney General Derek Schmidt to investigate. CURB argues the KCC members approved the rate increase by a process called "pink sheeting," in which members individually approve the request without holding a public hearing.

KCC attorneys argue the process is legal when commissioners are unable to meet together.
