5 U.S.C. § 8314 — Refusal to testify

(a) An individual — or their survivor or beneficiary — can't be paid annuity or retired pay based on that individual's creditable service, apart from the section 8311(2) and (3) exceptions, if, before, on, or after September 1, 1954, they refused or refuse, or knowingly and willfully failed or fail, to appear, testify, or produce a book, paper, record, or other document about their service as an employee. This applies when they were asked, in a proceeding before a federal grand jury, U.S. court, court-martial, or congressional committee, about (1) their past or present relationship with a foreign government, or (2) a matter involving or relating to a threat, plan, or attempt to interfere with or endanger U.S. national security or defense. (b) The payment ban applies to the period after the date of the individual's failure or refusal, or after September 1, 1954, whichever is later.
