(a) Except as in paragraph (b) of this section, claims of less than $2,500 exclusive of interest, penalties, and administrative costs, or such other amount as the Attorney General may prescribe, shall not be referred for litigation.
(1) Litigation to collect such smaller amount is important to ensure compliance with the policies and programs of the Department;
(2) The claim is being referred solely for the purpose of securing a judgment against the debtor, which will be filed as a lien against the debtor's property pursuant to 28 U.S.C. 3201 and returned to the Department for enforcement; or
(3) The debtor has the clear ability to pay the claim and the Government effectively can enforce payment, with due regard for the exemptions available to the debtor under State and Federal law and the judicial remedies available to the Government.
