Rufo’s complaint, filed in the county court, sought an order vacating this court’s rescript in Commonwealth v. Rufo, 429 Mass. 380 (1999) (Rufo I).2 In Rufo I, we vacated an order of a judge in the Boston Municipal Court that required the State Police to pay Rufo an amount equivalent to the value of currency seized from him at the time of his 1992 arrest for alleged motor vehicle infractions.3

The single justice dismissed Rufo’s complaint, in part, on the ground that he lacked authority to grant the relief sought, i.e., an order invalidating a decision of the full court. On appeal, Rufo concedes that the single justice was correct on this point. However, Rufo now raises numerous arguments not raised before the single justice, only one of which warrants discussion.4

Rufo contends that the court’s decision in Rufo 7 is a nullity because the court lacked subject matter jurisdiction to decide that case. Rufo argues that in *1052the course of deciding Rufo I, in which the court was exercising its jurisdiction to review determinations made in the Boston Municipal Court (see G.L. c. 211 A, § 10), the court usurped the exclusive subject matter jurisdiction of Federal courts over Federal forfeiture proceedings. See 28 U.S.C. § 1355(a) (2000). Rufo’s contention is without merit. In Rufo I, the central issue was the authority of a judge in the Boston Municipal Court to issue an order concerning funds seized by State law enforcement officials that had been turned over to Federal authorities and that were the subject of a Federal forfeiture proceeding. We concluded that in rem jurisdiction over the currency had been exercised by Federal authorities before the State court took any action relative to the funds, and that, as a result, the Boston Municipal Court judge lacked authority to enter orders concerning the disposition of the funds. Id. at 383-384.

Rufo’s contention that this court, in deciding Rufo I, acted in place of the Federal judiciary on a matter within its exclusive province, fails to apprehend that the court in Rufo I did not rule on the merits of the Federal forfeiture proceeding, but only considered it as part of the chronology of events when determining whether the Federal or State court asserted jurisdiction over the currency in the first instance. Indeed, the court expressly noted that it was not for this court to assess the validity of the Federal forfeiture proceeding.5 Rufo I, supra at 384 n.7. To the extent that Rufo’s argument is that this court lacked authority to interpret Federal law, the claim is clearly without merit and warrants no further discussion.

Judgment affirmed.
