PER CURIAM:

On June 4, 2011, Alquwon Johnson committed suicide by hanging himself with a bed sheet while in custody at the Barbour County Jail (the Jail). On August 8, 2011, his mother and personal representative, appellee Sherrie Johnson, filed suit against appellants Ryan Conner, Sonya Mayo, and George Parham, all of whom were corrections personnel working at the Jail at the time of Alquwon's suicide, as well as against various Barbour County entities.1 Johnson alleged that, despite their knowledge of Alquwon's mental illness, the appellants violated state and federal law by failing to take appropriate precautions — including, inter alia, closely monitoring Alquwon, ensuring that he took his medications, and removing the bedding from his cell in accordance with Jail policy — following Alquwon's previous but unsuccessful suicide attempt at the Jail on May 6, 2011.

The appellants filed a Federal Rule of Civil Procedure 12(b)(6) motion to dismiss Johnson's complaint on grounds of: (1) qualified immunity as to the federal claims; and (2) state immunity, pursuant to Alabama Code section 14-6-1, as to the state-based wrongful death claims. The district court granted the motion in part and denied it in part. With regard to section 14-6-1 — which became effective on June 14, 2011 and entitled jailer personnel "employed by the sheriff ... to the same immunities and legal protections granted to the sheriff" — the district court denied immunity, holding that the amended version of the statute "do[es] not apply to conduct which occurred before [its] effective date." Johnson v. Conner, No. 2:12-cv-00392-WHA, 2012 WL 3962012, at *6 (M.D.Ala. Sept. 10, 2012). The appellants then filed this interlocutory appeal, challenging only the denial of Alabama state immunity pursuant to section 14-6-1. After review and oral argument, we certify two questions to the Supreme Court of Alabama. See Forgione v. Dennis Pirtle Agency, Inc., 93 F.3d 758, 761 (11th Cir. 1996) (per curiam) ("When substantial doubt exists about the answer to a material state law question upon which the case turns, a federal court should certify that question to the state supreme court ...."); see also Ala. R.App. P. 18(a).

I. STANDARD OF REVIEW

"District court denials of state sovereign immunity under Alabama law are immediately appealable to this Court." LeFrere v. Quezada, 582 F.3d 1260, 1263 (11th Cir.2009). Sovereign immunity is a question of law that we review de novo. Tinney v. Shores, 77 F.3d 378, 383 (11th Cir.1996) (per curiam).

II. ALABAMA LAW

Pursuant to its state constitution, Alabama grants sovereign immunity to its state executive officers. Ala. Const. art. I, § 14. Section 14 provides that the State of Alabama shall never be made a defendant in any court of law or equity. Id. Under Alabama law, sheriffs and deputy sheriffs are considered executive officers of the state, and are therefore immune from suit in both their official and individual capacities. See McMillian v. Monroe Cnty., 520 U.S. 781, 793, 117 S.Ct. 1734, 1740, 138 L.Ed.2d 1 (1997) ("Alabama sheriffs, when executing their law enforcement duties, represent the State of Alabama...."); Drain v. Odom, 631 So.2d 971, 972 (Ala. 1994) ("We have also held that deputy sheriffs are immune to the same extent as sheriffs."); Parker v. Amerson, 519 So.2d 442, 442-43 (Ala. 1987) (answering a certified question from this court in the affirmative that "[a] sheriff is an executive officer of the State of Alabama, who is immune from suit under Article I, § 14 ...").

The only exceptions to Alabama sheriffs' immunity exist in actions brought

Alexander v. Hatfield, 652 So.2d 1142, 1143 (Ala.1994) (internal quotation marks omitted).

At issue in this case is the amended version of Alabama Code section 14-6-1, which, "effective immediately" as of June 14, 2011, extended state immunity to sheriffs' jailers.2 See 2011 Ala. Acts 685 section 3. The amended version of section 14-6-1 now provides:

Ala.Code § 14-6-1 (2013).3

III. CONTENTIONS OF THE PARTIES

A. Application of Immunity to Incidents Prior to the June 14, 2011 Amendment.

The parties' primary dispute on appeal is whether the immunity granted by section 14-6-1 applies to a claim filed after the statute's effective date, but in which the underlying conduct giving rise to the claim occurred before the statute's effective date. The appellants assert that because sheriffs' immunity under section 14 of the Alabama Constitution is an issue of subject matter jurisdiction, and because section 14-6-1 now provides that jailers "shall be entitled to the same immunities and legal protections granted to the sheriff under the general laws and the Constitution of Alabama of 1901," section 14-6-1 immunity is also an issue of subject matter jurisdiction. The Alabama Legislature has the authority to limit subject matter jurisdiction within various state entities, and when the amendment to section 14-6-1 became effective on June 14, 2011, Alabama courts were stripped of their jurisdiction to entertain claims against jailers, regardless of when the conduct at issue occurred. See Ala. Dep't of Corr. v. Montgomery Cnty. Comm'n, 11 So.3d 189, 192 (Ala.2008) (per curiam) (explaining that section 14 of the Alabama Constitution removes subject matter jurisdiction for actions against the state and that "[a]ny action taken by a court without subject-matter jurisdiction — other than dismissing the action — is void"). As such, the issue on appeal does not concern the retroactivity of the statute, but simply concerns the prospective divestment of subject matter jurisdiction from Alabama state courts.

Johnson, on the other hand, maintains that nothing in the language of section 14-6-1 makes the statute retroactively applicable. In fact, the statute's silence is dispositive here: under Alabama law, "retrospective application of a statute is generally not favored, absent an express statutory provision or clear legislative intent that the enactment apply retroactively as well as prospectively." Ex parte Bonner, 676 So.2d 925, 926 (Ala.1995) (internal quotation marks omitted). Because there is a presumption against retroactivity and the statute is silent on the matter, the 2011 amendment operates prospectively, and immunity is inapplicable in this case. Further, in the only Alabama Supreme Court case to reference the 2011 amendment, where the court examined whether immunity shielded a deputy sheriff from liability for conduct occurring before the effective date of the amendments, the court tersely wrote that "[t]he 2011 amendments are not applicable in this case." Ex parte Burnell, 90 So.3d 708, 714 n. 2 (Ala.2012).4

Johnson also disputes the appellants' argument that the date of filing should be operative in this case; rather, "substantive legal interests spring from the law in effect at the time such interests are alleged to have arisen or to have been violated." Ala. Power Co. v. Dir. of Indus. Relations, 36 Ala.App. 218, 54 So.2d 786, 788 (1951). Therefore, and because nothing indicates that the Alabama legislature intended section 14-6-1 to apply retroactively, the district court correctly denied immunity to the appellants in this matter.

B. Whether the Appellants' Conduct Was In Compliance with the Law for Purposes of Section 14-6-1 Immunity.5

The parties next dispute the scope of section 14-6-1's requirement that, to enjoy immunity, a jailer must have been acting in compliance with the law at the time of his or her conduct. The appellants interpret "in compliance with the law" to preclude immunity only where a defendant is acting in violation of the criminal code at the time of the conduct giving rise to the lawsuit. Any contrary interpretation would render the statute meaningless, because if "in compliance with the law" encompasses all tort or statutory duties, then it in fact confers no immunity at all — in any case where liability were present, immunity would not apply. "It is presumed that the legislature does not enact meaningless, vain or futile statutes." Ex parte Watley, 708 So.2d 890, 892 (Ala.1997) (per curiam) (alteration and internal quotation marks omitted). As such, the "in compliance with the law" requirement must be limited to preclude immunity only where a defendant violates the criminal law at the time of the conduct giving rise to liability.

Johnson counters that Alabama Code section 14-6-19 requires that jailers provide "necessary medicines and medical attention to those who are sick or injured." Ala.Code § 14-6-19 (2013). Therefore, when the appellants in this case engaged in the conduct giving rise to liability, they were not acting "in compliance with the law." See Ala.Code § 14-6-1. There is no evidence that the Alabama legislature intended to limit the exception to violations of the criminal law; if it had so intended, the legislature would have written the statute that way.

IV. CERTIFICATION

Because this appeal depends on questions of unsettled Alabama law, and because we believe "substantial doubt exists about the answer to a material state law question upon which the case turns," Forgione, 93 F.3d at 761, we certify the following questions to the Supreme Court of Alabama:

"The phrasing used in these certified questions is not intended to restrict the Supreme Court's consideration of the problems posed by this case. This extends to the Supreme Court's restatement of the issues and the manner in which the answers are given." Morales v. Zenith Ins. Co., 714 F.3d 1220, 1234 (11th Cir.2013). In order to assist the Supreme Court with its consideration of the case, the entire record, along with the parties' briefs, shall be transmitted to the Supreme Court of Alabama.

QUESTIONS CERTIFIED.
