BRANDON PRICE,
Respondent - Appellee.
Appeal from the United States District Court
for the Central District of California
Valerie Baker Fairbank, Senior District Judge, Presiding
Submitted February 13, 2025
Pasadena, California
Before: WALLACE, GRABER, and BUMATAY, Circuit Judges
Appellant Douglas MacKenzie appeals from the district court’s dismissal of
his petition for a writ of habeas corpus. 28 U.S.C. § 2241. We have jurisdiction
under 28 U.S.C. § 2253. MacKenzie is in pre-trial detention in a California hospital,
awaiting his civil commitment trial under California’s Sexually Violent Predator Act
(“SVPA”) to determine whether he is “currently” likely to “engage in sexually

violent criminal behavior.” Cal. Welf. & Inst. Code § 6600(a)(3). MacKenzie
claims that pre-trial detention violates his Fourth and Fourteenth Amendment rights.
The district court dismissed the petition under the abstention doctrine of Younger v.
Harris, 401 U.S. 37 (1971). We affirm.
1. MacKenzie first argues that he lacks an “adequate opportunity” to bring his
federal claims in state court because his state-court counsel refused to file state
habeas petitions raising his federal constitutional challenges to pretrial detention.
See Arevalo v. Hennessy, 882 F.3d 763, 765 (9th Cir. 2018) (describing four-part
standard for Younger abstention). The California courts dismissed his pro se
petitions without prejudice under a state rule that individuals represented by counsel
cannot simultaneously proceed pro se. See In re Barnett, 73 P.3d 1106, 1110 (Cal.
2003).
The difference of opinion over legal strategy between MacKenzie and his
former counsel is far from a state-imposed procedural bar to federal claims. See
Meredith v. Oregon, 321 F.3d 807, 818 (9th Cir.) (“Younger requires only the
absence of procedural bars to raising a federal claim in the state proceedings.”
(citations and internal quotation marks omitted)), as amended 326 F.3d 1030 (9th
Cir. 2003). And MacKenzie has recently been appointed new state counsel. He may
still raise his federal claims in the state courts with his new counsel. So Younger
abstention applies.

2. MacKenzie next argues that his petition falls within the two exceptions
recognized by Page v. King, 932 F.3d 898 (9th Cir. 2019): “(1) the procedure
challenged in the petition is distinct from the underlying criminal prosecution and
the challenge would not interfere with the prosecution,” and “(2) full vindication of
the petitioner’s pretrial rights requires intervention before trial.” Id. at 903.
Neither Page exception applies. First, if we held that MacKenzie is no longer
“currently” a sexually violent predator, we would interfere with the state proceedings
by deciding the exact issue to be litigated in his upcoming SVPA trial. See id. at 904
(holding that the first exception applies only when “an issue . . . could not be raised
in defense of the criminal prosecution” (simplified)).
Second, the full vindication of MacKenzie’s pre-trial rights does not require
intervention before trial. MacKenzie—unlike the petitioner in Page—does not
assert that California failed to hold a constitutionally adequate probable cause
hearing when he was first detained in 2011. Instead, he argues that the SVPA is
unconstitutional. Given that MacKenzie challenges the constitutionality of the state
law as a whole, he may vindicate his constitutional rights post-trial. If he is ordered
detained under the SVPA post-trial, a federal court may later pronounce the SVPA
unconstitutional.

3. Because we do not “find[] any ambiguity” as to the nature of MacKenzie’s
claims, there is—by MacKenzie’s own admission—no need for the district court to
have granted leave to amend.
AFFIRMED.
