I obtained all the filings in the Scooter Libby case - at least all those that were made available of PACER (argument in the Circuit Court was not, minute entries and transcripts in the District Court were not), many of which were "scanned in."
Pure speculation on my part that the ED of PA has lazy clerks. If it takes one more step to get the document on line, they don't.
It is a VERY BIG NO-NO if the docket clerks do not scan the docs into CM/ECF. It may take a day or two but they will get in. They must be in the case management system or else!
