PREMO
v.
GEORGIA PORTS AUTHORITY.
No. A97A1092.
Court of Appeals of Georgia.
June 20, 1997.
*107 Fletcher Farrington, Savannah, for appellant.
Thurbert E. Baker, Attorney General, Kilpatrick & Stockton, G.P. Sykes, Jr., Daniel F. Piar, Atlanta, Ranitz, Mahoney, Coolidge & Mahoney, Thomas J. Mahoney, Jr., Savannah, for appellee.
HAROLD R. BANKE, Senior Appellate Judge.
Walter D. Premo appeals the summary judgment granted to the Georgia Ports Authority ("GPA") on all his claims.
During a surveillance operation, a GPA police officer apprehended Premo, a GPA truck driver, inside a shipping container, an unauthorized area. Officials accused Premo of opening a carton containing television sets. Premo was taken into custody and subsequently charged with burglary and criminal trespass. A jury convicted Premo of criminal trespass but acquitted him of the burglary charge.
GPA terminated Premo for violating its "Code of Good Conduct" which prohibited incidents of misconduct of "a highly serious nature." Premo claims that according to this Code, being in an unauthorized area was an offense requiring one written warning and a second violation within a six-month period before the GPA could discharge him. Premo appealed his termination through GPA's internal grievance procedures. He met three times with GPA personnel who reviewed his version of events that he had an emergency need to answer nature's call and entered what he thought was an empty container to relieve himself. GPA deemed Premo's termination final after he purportedly failed to comply with grievance procedures mandating that he schedule a fourth appointment for review of his termination.
Premo subsequently obtained employment with a local trucking concern but was allegedly discharged from that job because the GPA denied him access to its port facility. Premo then filed the underlying action, contending that GPA violated his rights to due process and equal protection under the Georgia Constitution, and that GPA wrongfully interfered with his contractual relations and business opportunities with third parties when it terminated his employment and barred him from its premises. Premo sought general damages, special damages, and injunctive relief. After GPA moved for summary judgment, Premo timely filed a request for oral argument. Without conducting a hearing, the trial court ruled in favor of the GPA. Premo appeals.[1]Held:
1. Premo contends that the trial court erred in granting summary judgment to the GPA without affording him an opportunity to be heard pursuant to his request for oral argument under Uniform Superior Court Rule 6.3. Pit Stop v. Jackson, 216 Ga.App. 648 (1), 455 S.E.2d 358 (1995). We agree and reverse. Further, we decline the GPA's invitation to apply harmless error analysis. See Dixon v. McClain, 204 Ga. App. 531(1), 532, 420 S.E.2d 66 (1992) (failure to hold hearing not subject to harmless error rationale because permitting exceptions would discourage adherence to mandatary rule). In the interest of judicial economy, we address the following legal issues because they may recur on the trial of this case. See Townsend v. Wright, 220 Ga.App. 324, 327(2), 469 S.E.2d 281 (1996).
*108 2. The trial court erred in holding that Premo's claims in their entirety constituted torts within the meaning of the Georgia Tort Claims Act. OCGA § 50-21-20 et seq.
(a) Pretermitting consideration of their merit, all of Premo's claims falling within the purview of the Tort Claims Act were procedurally barred due to Premo's undisputed failure to comply with that Act's mandatory notice provisions. OCGA § 50-21-26. Thus, the GPA was entitled to summary judgment on Premo's claim for damages for tortious interference with his contractual relations and business opportunities with third parties. See Miller v. Ga. Ports Auth., 266 Ga. 586, 470 S.E.2d 426 (1996) (failure to comply with notice provisions of Georgia Tort Claims Act fatal to action against GPA, a State entity within the meaning of that Act).
(b) Premo also sought an injunction prohibiting the GPA from barring him from its premises and an order reinstating him to his former position. Inasmuch as these claims do not seek money damages, the Tort Claims Act is inapplicable. OCGA § 50-21-22(1). See IBM Corp. v. Evans, 265 Ga. 215, 216, 453 S.E.2d 706 (1995) (sovereign immunity inapplicable when State acts illegally and injunctive relief sought); compare State Bd. of Ed. v. Drury, 263 Ga. 429, 430(1), 437 S.E.2d 290 (1993) (damages not recoverable against State absent a waiver of sovereign immunity).
3. Notwithstanding his claim to the contrary, Premo had no property right or due process interest in his continued employment. It is undisputed that GPA is not covered by the State Merit System. OCGA § 45-20-2(7) (expressly excludes authorities). Premo's attempt to use the GPA handbook, which delineates dischargeable offenses and termination procedures, as a shield against his termination is unavailing. As we previously held, the GPA employee manual does not transform an at-will employee's status to a permanent lifetime employee. Ga. Ports Auth. v. Rogers, 173 Ga.App. 538, 539(1), 327 S.E.2d 511 (1985) (in the absence of a definite period of employment, employee's status remains at will). Because "[a]n indefinite hiring may be terminated at will by either party," GPA had the right to terminate Premo's employment. OCGA § 34-7-1. Accord Rogers v. Ga. Ports Auth., 183 Ga.App. 325, 328, 358 S.E.2d 855 (1987).
We reject Premo's urging to apply Deason v. DeKalb County, 222 Ga. 63, 148 S.E.2d 414 (1966) to these facts. That action was brought by a permanent county merit system employee for breach of a valid contract; whereas Premo was an hourly employee outside the protection of any merit system and without a written contract. Id. at 65, 148 S.E.2d 414. Thus, Premo's contractual claim for back pay necessarily must fail.
4. The GPA was entitled to summary judgment as a matter of law on the alleged violation of Premo's liberty interest. In his amended complaint, Premo asserted that the GPA violated his liberty interest by publishing false charges or publicizing false statements. See Rogers v. Ga. Ports Auth., 183 Ga.App. at 328(2), 358 S.E.2d 855 (proof of deprivation of liberty interest requires showing that GPA collected and publicized defamatory information). However, because the underlying conduct complained of is tortious and it is undisputed that Premo failed to provide the requisite notice to the State under OCGA § 50-21-26, GPA is entitled to summary judgment as a matter of law on this claim regardless of its merit. See Division 2.
5. The trial court must resolve whether the GPA illegally banned Premo from State property and whether Premo was entitled to injunctive relief. Premo asserts that the GPA violated his right to equal protection under the Georgia Constitution. Premo contends the GPA's action was racially motivated in that similarly situated individuals of a different race received more favorable treatment. Premo claims that a person of a different race committed the dischargeable offense of bringing a concealed weapon onto GPA's premises. Yet this person, after purportedly failing a polygraph test on the issue of his knowledge of the gun's presence, was reinstated to employment and not excluded from GPA's property. Further, as evidence that GPA treated a similarly situated person differently, Premo offered testimony that another truck driver who had been discharged *109 for misconduct involving suspected theft was permitted to drive onto GPA's premises.
The "government cannot cloak itself in the mantle of sovereign immunity when an injured party seeks to enjoin an illegal action." Evans, 265 Ga. at 216(1), 453 S.E.2d 706. The type of "illegal action" that justifies piercing sovereign immunity is action "under color of office but without lawful authority and beyond the scope of official power. [Cits.]" Chilivis v. Nat. Distrib. Co., 239 Ga. 651, 654(1), 238 S.E.2d 431 (1977). Thus, whether the GPA acted with illegal racial animus and denied Premo equal protection are material disputed questions of fact.
6. Based on the above divisions, Premo's remaining enumerations are moot.
Judgment reversed and case remanded with direction.
RUFFIN and ELDRIDGE, JJ., concur.
