Regardless of which standard is employed, the Court must conduct a document-by-document, fact-specific inquiry. See S.G.D. Eng'g, Ltd. v. Lockheed Martin Corp., No. CV-11-02493-PHX-DGC, 2013 WL 2297175, at *3 (D. Ariz. May 24, 2013) (adopting special master's report and recommendation). As an initial matter, Plaintiffs argue that several documents are not privileged because they would not "be deemed a traditionally legal document."
