JM 6-5.130
The United States may intervene in a civil action to assert a federal tax lien on property that is the subject of the action. See 26 U.S.C. § 7424. Where the United States intervenes in a state court action, it has the same right of removal as in cases where it is named a party to an action under 28 U.S.C. § 2410(a).
If, under emergency circumstances, IRS counsel requests the United States Attorney’s Office to take immediate action to intervene in a pending action, the United States Attorney’s Office should not move to intervene until the Chief of the appropriate Civil Trial Section has approved the intervention.
