In Murray v. Commonwealth, 455 Mass. 1016, 1016-1017, 918 N.E.2d 787 (2009), we *329described the petitioner's history of filing multiple improper and ultimately unsuccessful actions in this court to challenge his Massachusetts sentences. We put him "on notice that any future attempt to seek extraordinary relief from this court, pursuant to G. L. c. 214, § 1 ; G. L. c. 211, § 3 ; or otherwise, raising like claims may result in appropriate action by the court." Id. at 1017, 918 N.E.2d 787. We now order, therefore, that until such time as the petitioner actually begins serving his Massachusetts sentences, he shall not be permitted to file any further action in this court challenging the validity or status of his sentences or his entitlement to **1021parole, without prior approval of a single justice of this court.5
Judgment affirmed.
