It basically boils down to: OP committed (alleged) fraud. The government used a spreadsheet populated from the defrauded's database to come to a figure for fraud, and submitted the spreadsheet as evidence. OP contends he needs access to the original database to satisfy as evidence, as a spreadsheet is potentially modifiable, but apparently doesn't allege that the data was actually modified.
Or, put another way, OP is insisting that a formatted report of SELECT * FROM table WHERE user_id=10343; should be inadmissible as evidence in court.
Money quote from the judgement: "Many of Defendants' arguments are better placed as questions concerning authentication. However, as this was not raised in the briefs, any argument to this effect was waived."
