MEMORANDUM OPINION

ROSEMARY M. COLLYER, District Judge.

Defendants District of Columbia and Officer Kelvin King1 move to dismiss the complaints brought against them by twenty Plaintiffs who have sued Defendants for various constitutional claims under 42 U.S.C. § 1983 arising out of what Plaintiffs allege are unlawful convictions for driving while intoxicated ("DWI").2 Defendants argue that Heck v. Humphrey precludes these lawsuits because a civil suit brought under 42 U.S.C. § 1983, which challenges the validity of a criminal conviction or sentence, may only be brought if a plaintiff demonstrates that the conviction or sentence has been favorably terminated, i.e. "that the conviction or sentence has been reversed on direct appeal, expunged by executive order, declared invalid by a state tribunal authorized to make such determination, or called into question by a federal court's issuance of a writ of habeas corpus." 512 U.S. 477, 487, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994). Plaintiffs concede that these civil suits call into question the validity of their convictions or sentences, but counter that Spencer v. Kemna, 523 U.S. 1, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998), sets forth an exception to the "favorable-termination" requirement for those cases in which a plaintiff has no ability to attack his conviction via a habeas-type action.

The Court concludes that Heck remains binding precedent and the exception to "favorable-termination" voiced by the dicta of the concurring and dissenting judges in Spencer when habeas-type relief is unavailable is not binding on the Court. Furthermore, even if the Court were bound by the exception in Spencer, the District of Columbia has available habeas-type remedies to vacate Plaintiffs' DWI convictions, thereby making the Spencer exception inapplicable3 Accordingly, because sixteen of the twenty Plaintiffs do not have favorable terminations of their convictions, and because habeas-type remedies exist to do so, those sixteen Plaintiffs' cases will be dismissed without prejudice, and the remaining four Plaintiffs, whose DWI convictions have been favorably terminated, will remain part of this lawsuit.

I. FACTS

On various dates, Plaintiffs were individually arrested under suspicion of DWI. A conviction for DWI requires that the prosecutor prove that a defendant's blood alcohol level reached .08 grams per 210 liters of breath or above. D.C.Code § 50-2201.05(b)(1)(A)(i)(I). Proof of this element is supplied by a defendant's measured blood alcohol level tested on an Intoxilyzer 5000EN machine. On February 26, 2010, the District of Columbia announced that there was a potential problem with the accuracy of its Intoxilyzer machines. Compl. ¶ 134. Due to erroneous calibrations, the machines were generating readings that were allegedly thirty-percent higher than the actual blood alcohol level. Id. ¶ 92. As a result, the DWI charges and convictions that relied upon such blood alcohol levels are suspect.

Plaintiffs all allege the same five counts under 42 U.S.C. § 1983: (1) a violation of substantive due process, per the Fifth Amendment of the Constitution, based upon a right "to be free from criminal conviction based upon inaccurate and unreliable evidence manufactured by the District," id. ¶ 148; (2) a violation of substantive due process, per the Fifth Amendment of the Constitution, based upon a right "to be free from criminal conviction based on inaccurate and unreliable evidence manufactured by District employees who were improperly overseen, trained, and controlled in the manner in which they carry out their functions," id. ¶ 168; (3) a violation of substantive due process, per the Fifth Amendment of the Constitution, based upon a right "to be free from criminal conviction due to the District wrongfully withholding exculpatory material from the accused," id. ¶ 190; (4) a violation of the Eighth Amendment of the Constitution, based upon a right "to be free from cruel and unusual punishment," id. ¶ 205; and (5) a violation of substantive due process, per the Fifth Amendment of the Constitution, based upon a right "to be free from criminal conviction based upon inaccurate evidence manufactured by the District," directed at Defendant King in his individual capacity, id. ¶ 220.4 All of these alleged violations aim to undermine each Plaintiff's conviction for DWI.

Due to the dynamic procedural posture of the underlying cases and the attempts to withdraw some guilty pleas in some cases and request new trials on others, the Court ordered Plaintiffs to update the Court on the underlying criminal cases and how any changes to those cases affect this civil case. See Minute Entry Order 12/15/10. Plaintiffs responded on January 6, 2011. See Pls.' Consolidated Mem. of Changed Statuses ("First Changed Status") [Dkt. # 25]. On February 24, 2011, the Court stayed the case, denied Defendants' Motions to Dismiss [Dkt. ## 11, 16], without prejudice, and again ordered a status report as to the status of Plaintiffs' criminal cases by May 25, 2011. See Minute Entry Order 2/24/11. Plaintiffs filed such a report, and the following status exists.

Eighteen of the twenty Plaintiffs originally pled guilty to the DWI charge. See D.C. Reply [Dkt. # 21] at 8. The remaining two Plaintiffs, Messrs. Beemer and Nunez, contested the DWI charge and were found guilty after trial. Id. at 8-9. As of June 6, 2010, the date of the Complaint, Messrs. Beemer and Nunez had not moved for new trials. On August 20, 2010, upon motion by the District of Columbia, Plaintiff Nunez's conviction for DWI was vacated. Id. at 9 n. 8. His convictions for Driving Under the Influence ("DUI") and Operating While Intoxicated ("OWI"), however, remain valid. See D.C. Response to Pls.' Consolidated Mem. of Changed Statuses ("D.C. Response") [Dkt. # 29] at 2. On November 3, 2010, Mr. Beemer moved for a new trial; that motion is currently pending. See First Changed Status, Ex. I; see also Pls.' Second Consolidated Mem. of Changed Statuses ("Second Changed Status") [Dkt. # 31], Ex. H.

Only ten of the eighteen Plaintiffs who had pled guilty attempted to withdraw their pleas of guilty, and these motions were only filed after D.C.'s Reply of October 8, 2010, wherein D.C. noted that habeas-type procedures were available to these Plaintiffs. See D.C. Reply at 5-10. Mr. Fenwick's guilty plea to DWI has since been withdrawn and his case has been dismissed in full. See Second Changed Status at 4-5. Messrs. Manneh and Turner's guilty pleas to DWI have also been withdrawn, but they are awaiting trials related to the remaining DUI and OWI charges. Id. at 5-6. Messrs. Eckwood, Craig, Williams, Gordy, Bacon, Elissetche, and Clements have only recently, on May 17, 2011, attempted to withdraw their guilty pleas. The following eight Plaintiffs have not attempted to withdraw their pleas: Hector Molina-Aviles, Steven Broderick, Jacinta Council, Christina Mejia, William Calhoun, Thomas McCarthy, Kenneth Reyna, and Nicholas Sanchez.

II. LEGAL STANDARDS

A motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(6) challenges the adequacy of a complaint on its face, testing whether a plaintiff has properly stated a claim. Federal Rule of Civil Procedure 8(a) requires that a complaint contain "a short and plain statement of the claim showing that the pleader is entitled to relief." Fed.R.Civ.P. 8(a). A complaint must be sufficient "to give a defendant fair notice of what the ... claim is and the grounds upon which it rests." Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007) (internal citations omitted). Although a complaint does not need detailed factual allegations, a plaintiff's obligation to provide the grounds of his entitlement to relief "requires more than labels and conclusions, and a formulaic recitation of the elements of a cause of action will not do." Id. The facts alleged "must be enough to raise a right to relief above the speculative level." Id. Rule 8(a) requires an actual showing and not just a blanket assertion of a right to relief. Id. at 555 n. 3, 127 S.Ct. 1955. "[A] complaint needs some information about the circumstances giving rise to the claims." Aktieselskabet AF 21. Nov. 2001 v. Fame Jeans, Inc., 525 F.3d 8, 16 n. 4 (D.C.Cir.2008).

In deciding a motion under Rule 12(b)(6), a court may consider the facts alleged in the complaint, documents attached to the complaint as exhibits or incorporated by reference, and matters about which the court may take judicial notice. Abhe & Svoboda, Inc. v. Chao, 508 F.3d 1052, 1059 (D.C.Cir.2007). To survive a motion to dismiss, a complaint must contain sufficient factual matter, accepted as true, to state a claim for relief that is "plausible on its face." Twombly, 550 U.S. at 570, 127 S.Ct. 1955. When a plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged, then the claim has facial plausibility. Ashcroft v. Iqbal, 556 U.S. 662, 129 S.Ct. 1937, 1949, 173 L.Ed.2d 868 (2009). "The plausibility standard is not akin to a `probability requirement,' but it asks for more than a sheer possibility that a defendant has acted unlawfully." Id.

A court must treat the complaint's factual allegations as true, "even if doubtful in fact." Twombly, 550 U.S. at 555, 127 S.Ct. 1955. But a court need not accept as true legal conclusions set forth in a complaint. Iqbal, 129 S.Ct. at 1949. "Threadbare recitals of the elements of a cause of action, supported by mere conclusory statements, do not suffice." Id. "While legal conclusions can provide the framework of a complaint, they must be supported by factual allegations. When there are well-pleaded factual allegations, a court should assume their veracity and then determine whether they plausibly give rise to an entitlement to relief." Id. at 1950.

III. ANALYSIS

Heck v. Humphrey held that a civil suit brought under 42 U.S.C. § 1983 that challenges the validity of a criminal conviction or sentence may only be brought if the plaintiff demonstrates "that the conviction or sentence has been reversed on direct appeal, expunged by executive order, declared invalid by a state tribunal authorized to make such determination, or called into question by a federal court's issuance of a writ of habeas corpus, 28 U.S.C. § 2254." 512 U.S. at 487, 114 S.Ct. 2364. In such a case, "the district court must consider whether a judgment in favor of the plaintiff would necessarily imply the invalidity of his conviction or sentence; if it would, the complaint must be dismissed unless the plaintiff can demonstrate that the conviction or sentence has already been invalidated." Id.

Plaintiffs do not deny that their success in these lawsuits would imply the invalidity of the DWI convictions, but they argue that Heck has subsequently been limited by Spencer. In a concurring opinion in Spencer, Justice Souter, joined by three concurring Justices and a dissenting Justice Stevens, reaffirmed his own Heck concurrence that Heck's favorable-termination principle does not apply when no habeas-type relief is available, e.g. such as when a defendant is no longer incarcerated. Justice Souter's analysis conflicted with the majority in Heck, which stated that the favorable-termination principle would "not [be] rendered inapplicable by the fortuity that a convicted criminal is no longer incarcerated." Heck, 512 U.S. at 498 n. 10, 114 S.Ct. 2364; see also Aleotti v. Baars, 896 F.Supp. 1, 8 (D.D.C.1995) (finding Heck precludes a § 1983 lawsuit even when a plaintiff is not incarcerated). The Supreme Court retains the sole prerogative to overrule its own decisions. See, e.g., Tenet v. Doe, 544 U.S. 1, 10-11, 125 S.Ct. 1230, 161 L.Ed.2d 82 (2005) (citing Rodriguez de Quijas v. Shearson/American Express, Inc., 490 U.S. 477, 484, 109 S.Ct. 1917, 104 L.Ed.2d 526 (1989)). It has not done so on this point of law.5 The Court concludes that the fractured group of five concurring and dissenting Justices in Spencer cannot be found to have overruled the majority decision in Heck.6 Whether the current Supreme Court—absent three of the retired Spencer Justices on whom Plaintiffs rely— agrees remains to be seen. This Court concludes that it is bound by the majority in Heck unless and until the Supreme Court speaks clearly. Accordingly, the Court concludes that Heck precludes any § 1983 suit challenging a criminal conviction that has not already been favorably terminated, regardless of the availability of habeas-type relief.

Even it the exception to favorable-termination was binding in the absence of habeas-type procedures, it would not save any complaints here because the District of Columbia has habeas-type relief available for all of Plaintiffs—the very condition to which Spencer attempted to carve out an exception to Heck. Plaintiffs (1) could have brought a habeas claim while on probation, see D.C.Code § 23-110 (2011) (the District of Columbia's habeas statute); (2) could have filed a motion pursuant to D.C. Criminal Rule 32(e), after sentence, to "set aside the judgment of conviction and permit the defendant to withdraw the plea," if the Plaintiff had pled guilty; or (3) could have filed a motion under Superior Court Rule 33 to "grant a new trial to the defendant if the interests of justice so require" if the Plaintiff was convicted after trial. In fact, now that Plaintiffs have become aware of these habeas-type reliefs, they have applied for relief, thereby undermining their Spencer argument.

First, § 23-110 affords each of the Plaintiffs the ability to vacate their convictions while "in custody." Individuals on probation are "in custody" both for purposes of § 23-110 and the federal habeas statute. See Snell v. United States, 754 A.2d 289, 291-92 (D.C.2000) (finding that "in custody" under § 23-110 includes probationers, as in federal habeas proceedings); see also Jones v. Cunningham, 371 U.S. 236, 243, 83 S.Ct. 373, 9 L.Ed.2d 285 (1963). Each of the Plaintiffs was sentenced to a term of probation, thereby giving each an ability to attack his conviction.7 See D.C.'s Reply at 7. None of the Plaintiffs had availed themselves of § 23-110 as of the beginning of this lawsuit.

Second, D.C. Criminal Rule 32(e) affords those Plaintiffs who entered guilty pleas an opportunity to withdraw those pleas. Eighteen of the twenty Plaintiffs pled guilty to the DWI charge. See D.C.'s Reply at 8. When this civil lawsuit was filed, none of the eighteen Plaintiffs who pled guilty had availed themselves of this potential habeas-type relief. In fact, only after Defendants attacked Plaintiffs' Spencer argument as inapplicable, due to the availability of D.C. habeas-type procedures, did some Plaintiffs avail themselves of D.C. Criminal Rule 32(e).

Third, Superior Court Rule 33 affords Plaintiffs who have been convicted after trial to move for a new trial when the interests of justice require. Messrs. Beemer and Nunez contested their DWI charges at trial and were convicted. See D.C.'s Reply at 8. Again, when they instituted suit, neither Mr. Beemer nor Mr. Nunez had availed himself of this potential habeas-type relief. Only after Defendants attacked Plaintiffs' Spencer argument did Mr. Beemer move for a new trial pursuant to Superior Court Rule 33, and it was D.C. that moved for Mr. Nunez's new trial after the Complaint was filed.

Because habeas-type remedies were available to all twenty Plaintiffs, the Spencer exception is simply not applicable, regardless of whether it is binding. It also bears repeating that twelve of the Plaintiffs have now used these habeas-type procedures, thereby undermining Plaintiffs' argument that Spencer applies because there are no habeas-type procedures available.
