Good Morning You Prod. v. Warner/Chappell Music, No. 2:13-cv-04460 (C.D. Cal. filed 07/25/14) (Doc. 132).
The Court concluded that the 1979 transmittal by a music publisher to ASCAP, of letters prepared by the publisher's attorneys, did not waive the attorney-client privilege applicable to those materials. The letters "speak directly to the validity of the copyrights" in the song Happy Birthday To You. "The [transmittal] letter is silent as to the specific reason why [the publisher] provided materials from its outside lawyer to the association’s lawyer regarding the validity.
