So in casual terms, Sweeney is pissed at the plaintiffs and is letting defendants use the "honor" system so plaintiffs can't say Sweeney showed bias in production of documents?
Judge Sweeney's emotional states are unknown from here. Since it is not her task to sift through the 11,000-12,000 documents to select which ones fit the acceptable court criteria given, that leaves either the Plaintiffs or the Defendants to do the job. The Plaintiffs suggestion for "quick peek" was rejected as inappropriate procedurally and that left only the Defendants to do it on the "honor system." The omitted documents can be challenged by the the Plaintiffs.
