8 Petitioner, ORDER SCREENING PETITION, 9 v. DISMISSING WITH LEAVE TO AMEND 10 EDWARD BORLA,
Respondent. 11
12 13 Petitioner Isadore Christopher Diaz, a state prisoner, filed the instant pro se petition for 14 writ of habeas corpus. The petition is now before the Court for review pursuant to Rule 4 of the 15 Rules Governing § 2254 Cases. For the reasons set forth below, the petition is DISMISSED 16 WITH LEAVE TO AMEND. 17 I. BACKGROUND 18 Diaz entered a nolo contendere plea in Santa Clara County Superior Court to second 19 degree murder (Cal. Pen. Code § 187(a)), battery causing serious bodily injury (Cal. Pen. Code 20 § 245(a)(4)), misdemeanor battery (Cal. Pen. Code § 243(d)), brandishing a weapon (Cal. Pen. 21 Code § 417(a)), and resisting arrest (Cal. Pen. Code § 148(a)(1)).1 The charges arose from a series 22 of incidents at the Buena Vista Mobile Home Park in Palo Alto on June 24, 2019, during which 23 Diaz allegedly stabbed neighbor Timothy Wood while the men smoked methamphetamine, 24 battered a neighbor who was nearby as Diaz tried to flee the site of the murder, battered a different 25 neighbor who refused to drive him out of the mobile home park, and attempted to punch a sheriff 26 deputy after Diaz was arrested and transported to county jail. See ECF No. 1 at 15-16. 27 1 Diaz alleges that the trial court violated his Fourteenth Amendment rights in denying his 2 sentencing motion to dismiss a prior strike pursuant to People v. Superior Court (Romero), 13 Cal. 3 4th 497 (1996), and that the California Court of Appeal violated his Fourteenth Amendment and 4 Sixth Amendment rights when it found that Diaz could not challenge his plea despite alleged false 5 testimony by unnamed witnesses and Diaz’s “misunderstanding” of the consequences of the plea 6 due to his brain injury, which rendered his plea “unknowing and unintelligent.” ECF No. 1 at 36. 7 Specifically, Diaz alleges as follows: The reason why Diaz did not really understand his plead can be 8 demonstrated by Psy. D. Laeeq Evered’s report indicating Diaz has serious brain damage, PTSD, scores suggest he has great difficulty 9 processing more th[a]n modestly complex information, his accuracy becomes seriously impaired, he was shot in the head, had a car 10 accident head injury, he is unable to adequately understand what he is responding to as things become complex or stressful, Diaz ability 11 to understand and resolve challenges is more similar to that of a 12 year old child than adult. . . I didn't really understand what I was doing 12 when I signed. I didn't know I was taking two strikes. 13 ECF No. 1 at 35. He cites to Boykin v. Alabama, 395 U.S. 238 (1965) in support of his claim. 14 II. LEGAL STANDARD 15 District courts may entertain a petition for a writ of habeas corpus on “behalf of a person in 16 custody pursuant to the judgment of a State court only on the ground that [the person] is in 17 custody in violation of the Constitution or laws or treaties of the United States.” 28 U.S.C. 18 § 2254. The court shall “award the writ or issue an order directing the respondent to show cause 19 why the writ should not be granted, unless it appears from the application that the applicant or 20 person detained is not entitled thereto.” 28 U.S.C. § 2243. 21 III. DISCUSSION 22 The Court discusses each claim below. 23 A. Denial of Romero Motion 24 Whether the trial court correctly used its discretion in denying Diaz’s Romero motion is a 25 matter of state—not federal—law. Brown v. Mayle, 283 F.3d 1019 (9th Cir. 2002), overruled on 26 other grounds, 538 U.S. 901 (2003) (holding that a trial court’s refusal to exercise its discretion 27 and strike prior felony convictions is not cognizable on federal habeas review). State law claims 1 applied. See Swarthout v. Cooke, 562 U.S. 216, 219 (2011) (citing Estelle v. McGuire, 502 U.S. 2 62, 67 (1991)). Here, because Diaz’s claim challenges the correctness of the trial court’s use of its 3 discretion, unless he can explain how his constitutional rights were violated, Diaz cannot state a 4 constitutional claim. See, e.g., Smith v. Ryan, 823 F.3d 1270, 1282 (9th Cir. 2016). 5 Accordingly, the Court finds that Diaz’s current Romero claim is not cognizable and must 6 be dismissed. Diaz is granted LEAVE TO AMEND so he may explain how the trial court’s 7 denial of his Romero motion implicated his constitutional rights, provided he can do so in good 8 faith. 9 B. Challenge to Plea 10 Under California law, a “plea of nolo contendere ‘is the functional equivalent of a guilty 11 plea.’” United States v. Anderson, 625 F.3d 1219, 1220 (9th Cir. 2010) (quoting People v. 12 Whitfield, 46 Cal. App. 4th 947, 959 (1996)). A defendant who pleads guilty or nolo contendere 13 generally may not collaterally challenge a voluntary and intelligent guilty plea entered with the 14 advice of competent counsel. United States v. Broce, 488 U.S. 563, 574 (1989); Mabry v. 15 Johnson, 467 U.S. 504, 508 (1984). Nor may he collaterally attack his plea’s validity merely 16 because he made what turned out, in retrospect, to be a poor deal. Bradshaw v. Stumpf, 545 U.S. 17 175, 186 (2005). 18 A defendant who pleads guilty cannot later raise in habeas corpus proceedings independent 19 claims relating to the deprivation of constitutional rights that occurred before the plea of guilty. 20 See Haring v. Prosise, 462 U.S. 306, 319–20 (1983); Tollett v. Henderson, 411 U.S. 258, 266–67 21 (1973). After a defendant has entered a guilty or nolo contendere plea, the only challenges left 22 open on federal habeas corpus review concern the (1) voluntary and intelligent character of the 23 plea; and (2) adequacy of the advice of counsel. Womack v. Del Papa, 497 F.3d 998, 1002 (9th 24 Cir. 2007) (quoting Hill v. Lockhart, 474 U.S. 52, 56–57 (1985)). 25 Here, to the extent that Diaz complains about alleged false testimony prior to his 26 conviction, federal habeas relief on this claim is barred by his subsequent nolo contendere plea 27 except in circumstances not present here. See Tollet, 411 U.S. at 266–67 (generally, guilty plea 1 U.S. 306, 320 (1983) (jurisdictional challenge permitted on federal habeas following guilty plea); 2 Menna v. New York, 423 U.S. 61 (1975) (double jeopardy challenge permitted).

Challenge to Plea 10 Under California law, a “plea of nolo contendere ‘is the functional equivalent of a guilty 11 plea.’” United States v. Anderson, 625 F.3d 1219, 1220 (9th Cir. 2010) (quoting People v. 12 Whitfield, 46 Cal. App. 4th 947, 959 (1996)). A defendant who pleads guilty or nolo contendere 13 generally may not collaterally challenge a voluntary and intelligent guilty plea entered with the 14 advice of competent counsel. United States v.

New York, 423 U.S. 61 (1975) (double jeopardy challenge permitted). However, Diaz’s 3 claim that his brain damage impaired his ability to understand his nolo contendere plea, rendering 4 the plea “unknowing and unintelligent” in violation of Boykin, 395 U.S. 238, is not plainly 5 meritless, and warrants an answer from Respondent. ECF No. 1 at 36. 6 IV. CONCLUSION 7 The Court orders as follows: 8 1. Diaz’s claim that his nolo contendere plea violated his constitutional rights under 9 Boykin, 395 U.S. 238, is not plainly meritless and warrants an answer from 10 Respondent. 11 2. The remaining claims are dismissed as specified above. 12 3. Diaz has been granted leave to amend his petition as to his sentencing claim only. 13 The amended petition must be filed within twenty-eight (28) days of the date this 14 order is filed and must include the caption and civil case number used in this order 15 and the words “Amended Petition” on the first page. Because an amended petition 16 completely replaces the original, Diaz must include all claims and allegations of 17 fact to support his claims. See Ferdik v. Bonzelet, 963 F.2d 1258, 1262 (9th Cir. 18 1992). Diaz is cautioned that he may not incorporate material from the prior 19 complaint by reference. He must reallege all claims he wants to pursue within the 20 body of his amended petition, including his cognizable Boykin claim. Failure to 21 amend within the designated time will result in this action moving forward 22 only as to Diaz’s claim under Boykin, 395 U.S. 238. 23 4. It is Diaz’s responsibility to prosecute this case. He must keep the Court informed 24 of any change of address by filing a separate paper with the Clerk headed “Notice 25 of Change of Address,” and must comply with the Court’s orders in a timely 26 fashion. Failure to do so may result in the dismissal of this action for failure to 27 prosecute pursuant to Federal Rule of Civil Procedure 41(b). ] 5. The Clerk is requested to send a blank habeas corpus petition form to Diaz with his 2 copy of this order. 3 IT IS SO ORDERED. 4 || Dated: May 18, 2026 5 Noél Wise 6 United States District Judge 7 8 9 10 1] a 12
