Teacher Robert Collins worked for the School Board of Dade County, Florida. In November 1983, some horseplay in one of his classes escalated into an altercation in which he bit a student. The School Board, following the recommendation of Superintendent Leonard Britton, suspended Collins for 10 days in January 1984.

On January 23, 1984, Collins requested an administrative hearing to review his suspension. Eight days later, the School Board forwarded Collins' request to the Florida Division Of Administrative Hearings (“DOAH”).1 The DOAH’s hearing officer scheduled the case for July 18, 1984. On July 11, 1984, Collins requested and received a continuance, delaying the hearing until November 2, 1984. On July 3, 1985, the hearing officer recommended that Collins’ suspension be reversed and that he receive back pay, and the School Board followed this recommendation at its August 1985 meeting.

In 1989, Collins brought a 42 U.S.C. § 1983 action against five School Board members, Britton and other School Board officials, charging them with depriving him of his right to due process because of the lengthy postsuspension proceedings. Defendants asserted qualified immunity in their individual capacities, but the district judge expressly reserved ruling on this defense “pending the trial in this action.” Defendants appeal, contending that the district court should have granted them summary judgment.

Reserved Ruling Is Immediately Appealable

Defendants are entitled to immediate appeal when a district court denies their motion for summary judgment based on qualified immunity. Mitchell v. Forsyth, 472 U.S. 511, 530, 105 S.Ct. 2806, 2817, 86 L.Ed.2d 411 (1985); Bennett v. *1205Parker, 898 F.2d 1530, 1532 (11th Cir. 1990). Qualified immunity is “an immunity from suit rather than a mere defense to liability.” Mitchell, 472 U.S. at 526, 105 S.Ct. at 2815.

The district court’s order declining to rule on the qualified immunity issue pending trial effectively denies defendants the right not to stand trial. Because the “reserved ruling” is not materially different from an outright denial of a summary judgment motion, an immediate appeal on the qualified immunity issue is permissible.

That Collins has other claims pending against the School Board officials does not affect this determination.2 “In a practical sense, refusing to hear appeals such as this one would effectively abolish qualified immunity for [these] defendants, clearly frustrating both Mitchell and Harlow [v. Fitzgerald, 457 U.S. 800, 102 S.Ct. 2727, 73 L.Ed.2d 396 (1982) ] by forcing government officials to. litigate claims from which they are immune simply because other claims will proceed to trial regardless_ Nothing in Mitchell and Harlow says that a defendant has a right to qualified immunity only if the plaintiff does not assert other claims from which the defendant has no immunity.” Green v. Brantley, 941 F.2d 1146, 1150-51 (11th Cir. 1991).

Qualified Immunity For Postsuspension Proceedings

In Mitchell, 472 U.S. at 528, 105 S.Ct. at 2817 (1985), the Supreme Court wrote that

[a]n appellate court reviewing the denial of the defendant’s claims of immunity need not consider the correctness of the plaintiff’s version of the facts, nor even determine whether the plaintiff’s allegations actually state a claim. All it need determine is a question of law: whether the legal norms allegedly violated by the defendant were clearly established at the time of the challenged action ...

Collins claims that the 19 months from the time of his request for an administrative hearing to the resolution of his case clearly violated his due process right to prompt postsuspension proceedings. In Cleveland Bd. of Education v. Loudermill, 470 U.S. 532, 547, 105 S.Ct. 1487, 1496, 84 L.Ed.2d 494 (1985), the Supreme Court did note that, “[a]t some point, a delay in the post-termination hearing would become a constitutional violation.”3 A 9-month adjudication process, however, was not found unconstitutionally lengthy per se. Id. And the Court observed that, absent evidence of unreasonable prolongation by defendants, the fact of a long hearing process may suggest only that the process was thorough. Id. Most important for qualified immunity purposes, Loudermill established no bright line test for when a delay would become a constitutional violation.4 See generally Barts v. Joyner, 865 F.2d 1187, 1194 (11th Cir. 1989) (“Harlow’s ‘clearly established’ standard requires that a bright line be crossed” if defense of qualified immunity is to be overcome).

No controlling decision involved facts materially similar to the ones that are undisputed by Collins in this case; so, the law did not clearly proscribe defendants’ acts when they acted.5 The delays caused by defendants here were far less substantial than those at issue in Loudermill. The School Board referred the Collins matter to *1206the DOAH within eight days of his request for a hearing. And once the DOAH’s officer made her recommendation, the Board compensated Collins in a little over a month. For 17 of the 19 months in question, the course of the proceedings was outside the control of the Dade County School Board officials.6 That Collins caused much of the delay with his request for a continuance from an earlier hearing date is also important.7

Although the hearing ultimately exonerated Collins, this fact entitles Collins to no retroactive relief against Dade County school officials for failing to exonerate him faster. At the time defendants acted by referring the Collins matter to the appropriate state agency and then by waiting for the ordinary process to conclude, they violated no clearly established law. Because the reserved ruling is immediately appeal-able and defendants are qualified for immunity on the postsuspension due process issue, we REVERSE the denial of summary judgment on qualified immunity and REMAND for further proceedings.
