	UNITED STATES COURT OF APPEALS

TENTH CIRCUIT

EUEL DONAHOU,

		Plaintiff-Appellant,	

No. 05-5181	
	v.	(N.D. of Okla.)	
STATE OF OKLAHOMA,

		Defendant-Appellee.	(D.C. No. CV-05-432-JHP)		

	ORDER AND JUDGMENT*

Before KELLY, O’BRIEN, and TYMKOVICH, Circuit Judges.**  

	Plaintiff-Appellant Euel Donahou, proceeding pro se, appeals the dismissal of his suit against the State of Oklahoma under 42 U.S.C. § 1983, in which he alleged a violation of his due process rights in conjunction with a domestic relations matter in state court.  Because we agree with the district court that we lack subject matter jurisdiction over Donahou’s claim, we affirm its dismissal of the complaint.  Additionally, we deny Donahou’s motion to proceed in forma pauperis.
I. Discussion
	We review a district court’s dismissal for lack of subject matter jurisdiction de novo.  United States v. Rodriguez-Aguirre, 414 F.3d 1177, 1181 (10th Cir. 2005).  This case represents an appeal of Donahou’s fourth federal court filing regarding allegations that Oklahoma officials and courts failed to adequately take into account certain evidence in the course of his domestic relations dispute with his ex-wife.  Three previous cases have been dismissed by the district court.  One of the dismissals was appealed to us.  See Donahou v. Oklahoma, 153 F. App’x 471, 472 (10th Cir. 2005) (Donahou I) (unpublished) (affirming the dismissal of Donahou’s claims under the Rooker-Feldman doctrine).
	In this appeal, Donahou raises the same state law claims previously dismissed by the district court and affirmed on appeal.  For the reasons set forth in Donahou I, we affirm the district court’s order of dismissal in this case.  It is once again clear that Donahou impermissibly seeks to undo state court decisions by raising in federal court, constitutional issues which are inextricably intertwined with those state court judgments and thus could have been raised on direct appeal in state court.  See District of Columbia Court of Appeals v. Feldman, 460 U.S. 462, 483 n.16 (1983) (extending the holding of Rooker v. Fidelity Trust Co., 263 U.S., 413 (1923) to prohibit lower federal courts from hearing claims that are inextricably intertwined with a state court judgment).  Due to the frivolity of his claim, we deny Donahou’s motion to proceed in forma pauperis.  
II. Sanctions
    	In addition, we sua sponte bar Donahou, under penalty of sanction by this court, from filing additional appeals regarding the same subject matter as Donahou I and the instant appeal.  See generally Christensen v. Ward, 916 F.2d 1462, 1469 (10th Cir. 1990) (noting this court has the power “to impose sanctions such as costs, attorneys fees and double costs for the filing of frivolous appeals, Fed. R. App. P. 38, and the inherent power to impose sanctions that are necessary to regulate the docket, promote judicial efficiency, and . . . to deter frivolous filings.”). 
III. Conclusion
	For the reasons stated above, we AFFIRM the district court’s dismissal of Donahou’s complaint under the Rooker-Feldman doctrine, and DENY Donahou’s motion to proceed in forma pauperis.
