The 18 U.S.C. 1621 page collects the sworn-statement issue. The filings use this statute when they claim a verified assertion was materially false and made under oath or under a perjury-equivalent certification.
The audit method is simple: identify the exact sworn statement, identify the record that contradicts it, then ask whether the signer had personal knowledge, access to the contrary record, and a duty to correct.
The page is intentionally framed as a public-record guide. It helps a reader find the right exhibit, ask for the right log, and avoid turning a document conflict into an unsupported conclusion.
