Supreme Court of New Jersey.

NEW JERSEY TRANSIT PBA LOCAL 304, Plaintiff-Appellant,

v.

NEW JERSEY TRANSIT CORPORATION, Defendant-Respondent.

Argued April 28, 1997.

Decided Sept. 25, 1997.

 

Union representing transit police officers brought suit challenging constitutionality of transit authority's random drug and alcohol testing of employees in safety-sensitive positions.   The Superior Court, Law Division, Essex County, Alvin Weiss, J., entered summary judgment for transit authority, and union appealed.   The Superior Court, Appellate Division, 290 N.J.Super. 406, 675 A.2d 1180, affirmed.   Certification was granted.   The Supreme Court, Poritz, C.J., held that: (1) special needs balancing test, used in determining lawfulness of suspicionless search of public employees under Fourth Amendment, would be adopted as analytical framework for considering lawful of drug testing program under New Jersey Constitution's search and seizure provision, overrulingFraternal Order of Police, 216 N.J.Super. 461, 524 A.2d 430, and (2) random drug testing of transit police force was not unreasonable under State Constitution, in light of transit officers' decreased expectation of privacy, adequate limitations on obtrusiveness of testing, and compelling state interest in promoting safe conduct by armed officers.

 

Affirmed.

The opinion of the Court was delivered by

 

PORITZ, C.J.

To comply with regulations promulgated by the Federal Transit Administration (“FTA”), defendant, New Jersey Transit Corporation (“NJ Transit” or “Agency”), adopted a drug and alcohol testing policy that includes random testing of employees responsible*535  for safety-sensitive functions.   Plaintiff New Jersey Transit PBA Local 304 (“PBA” or “plaintiff”), challenged the constitutionality of the random testing provisions applicable to NJ Transit police officers.   The Law Division granted summary judgment in favor of NJ Transit, and the Appellate Division**1245  affirmed.  290 N.J.Super. 406, 675 A.2d 1180 (1996).   We granted certification, 147 N.J. 259, 686 A.2d 761 (1996), to consider whether mandatory random drug testing of transit police officers who carry firearms for security purposes violates the officers' right to be free from unreasonable searches and seizures as guaranteed by Article 1, Paragraph 7 of the New Jersey Constitution.   We now affirm.

 

 

I

 

-A-

 

 

NJ Transit is a public corporation within the Department of Transportation responsible for acquiring, operating, and improving public transportation facilities in New Jersey.  N.J.S.A. 27:25-2, -4a, -5, -10.   By its enabling legislation, the Agency is authorized to “comply with federal statutes, rules and regulations, and qualify for and receive all forms of financial assistance available under federal law to assure the continuance of, or for the support or improvement of public transportation.”  N.J.S.A. 27:25-5g.   At the present time, NJ Transit receives substantial federal funding from the FTA which, by the end of fiscal year 1996, had contracted to provide approximately $1 billion in current and future assistance to the Agency.

 

The NJ Transit Police Department was established within the Agency to provide police and security protection to all NJ Transit locations and services.    N.J.S.A. 27:25-15.1a. Transit police officers “have general authority, without limitation, to exercise police powers and duties ... in all criminal and traffic matters at all times throughout the state.”  Ibid. They must comply with policies established by the Attorney General, ibid., and must satisfy “requirements established by the Police Training Commission,”  *536  N.J.S.A. 27:25-15.1c. As officers of a state police force, they are permitted to carry firearms, see N.J.S.A. 2C:39-6a(7)(a), and to use deadly force in certain circumstances, N.J.S.A. 2C:3-3, -7.

 

Plaintiff is the majority representative of approximately one hundred twenty-five transit police officers under the rank of captain.   Six of the officers were assigned to ride on the Agency's trains as of April 1995;  the others perform patrol and investigatory police duties and functions similar to those performed by municipal and county police officers.   The majority are assigned to patrol NJ Transit's main terminals in Newark, Hoboken and Atlantic City, and carry out their responsibilities among heavy concentrations of transit riders.   The remaining officers are assigned to patrol smaller train stations and railroad rights-of-way throughout the state.

 

 

-B-

 

In 1991 Congress enacted the Omnibus Transportation Employee Testing Act of 1991 (“Act” or “Federal Act”), Pub.L. 102-143, 105 Stat. 952 (1991) (codified as amended in scattered sections of 49 U.S.C.A.), to address alcohol and drug testing of workers in safety-sensitive positions throughout the transportation industry.   Relevant here, the Act as amended directs the Secretary of Transportation to issue rules requiring mass transit operators receiving federal funds to conduct pre-employment, reasonable suspicion, random, and post-accident testing for drug and alcohol use by employees responsible for safety-sensitive functions.  49 U.S.C.A. §  5331(b).   As considered appropriate by the Secretary and provided in the rules, employees determined “to have used or been impaired by alcohol when on duty” or “to have used a controlled substance, whether or not on duty,” unless allowed for medical reasons, may be disqualified for a specified period or dismissed from their employment.  Id. §  5331(c)(1).   Congress expressly provided that failure to institute the specified drug and alcohol testing programs would result in ineligibility for federal funding.  Id. §  5331(g).

 

 *537 The anti-drug and alcohol misuse policies applicable to mass transit operators are set forth in regulations issued under the Act. See 49 C.F.R. pts. 653, 654 (1997);  see also id. pt. 40 (setting forth procedures to be followed for drug and alcohol testing).   The regulations are designed “to deter and detect the use of prohibited drugs by covered employees,” id. §  653.3, and “to help prevent accidents and injuries resulting from the misuse of alcohol by employees who perform **1246 safety-sensitive functions,” id. §  654.1. More specifically, the regulations provide for random drug and alcohol testing of “covered employees,” id. § §  653.47, 654.35, defined as those employees who perform safety-sensitive functions including, among other things, “carrying a firearm for security purposes,” id. § §  653.7, 654.7.   Employees who refuse to participate in the testing program are required to cease performing safety-sensitive functions.   Id. § §  653.35(a), 654.29.

 

 

-C-

 

For the purpose of complying with the FTA regulations, NJ Transit instituted a comprehensive drug and alcohol-free workplace policy that became effective January 1, 1995.   NJ Transit's policy consists of a Core Policy and two Addenda.   See NJ TRANSIT Corporate-Wide Policy, Drug and Alcohol-Free Workplace Core Policy (January 1, 1995);  Drug and Alcohol-Free Workplace Policy-Addendum I (January 1, 1995) (requirements applicable to employees who perform safety-sensitive functions);  Drug and Alcohol-Free Workplace Policy-Addendum II (January 1, 1995) (requirements applicable to employees who perform rail-covered services).   The purpose and goals of the Core Policy are described in Sections I and II:

The purpose of this policy is to ensure that NJ TRANSIT operates in the safest and most efficient manner possible and to promote the safety and welfare of our employees and customers by creating a drug and alcohol-free workplace and ensuring that our employees are free from the effects of drugs and alcohol.

 

 

 .    .    .    .    .

NJ TRANSIT'S goal to achieve a drug and alcohol-free workplace shall be accomplished through the implementation of a comprehensive anti-drug and alcohol  *538 program based on deterrence, detection, assistance and enforcement.   The program objectives in support of this goal are to prevent drug and alcohol abuse, to assist employees who seek help, to detect drug and alcohol abuse, and to enforce NJ TRANSIT's policy.

 

 

The Core Policy sets forth the drug and alcohol testing program generally, while Addendum I “outlines those requirements of NJ TRANSIT's Drug and Alcohol-Free Workplace Policy that are applicable only to NJ TRANSIT employees who perform safety-sensitive functions.”   Addendum I §  I. In its complaint, plaintiff challenged both the random drug and random alcohol testing components of NJ Transit's policy as applied to “law enforcement personnel represented by PBA Local 304.”   However, plaintiff has not argued before this Court that the alcohol testing component of the program is unconstitutional.   We will therefore limit our review to PBA's claims vis-à-vis random drug testing as that testing is implemented by NJ Transit through Addendum I and the Core Policy.

 

Under Addendum I, all NJ Transit employees, including supervisors and volunteers, are subject to “pre-employment, reasonable suspicion, post-accident, random, return-to-duty, and follow up testing” if they perform safety-sensitive functions.   Id. §  IV.A-B. Because transit police officers carry firearms for security purposes, they perform a safety-sensitive function and are subject to random testing.   Id. §  II. Previously, transit police officers had been subject to drug testing as specified by the Attorney General's Revised Law Enforcement Drug Screening Guidelines (August 1990) (“Guidelines”).   The Guidelines, promulgated in October 1986 and revised in 1990, provided for drug testing of permanent police officers only when the employer had an individualized reasonable suspicion that the officer had used or was using controlled substances.  Id. at 8-1.   Addendum I substantially altered the rules for drug testing of transit officers.   Like other NJ Transit-covered employees, transit officers are now selected for unannounced testing “by a computer-based random number generator that is matched with the employee's [identification] number.”   Addendum I §  IX.B.

 

 *539 NJ Transit's Core Policy requires the Agency and its certified laboratory to “maintain clear and well-documented procedures for collection, shipment” and recording of specimens.   Core Policy §  IX.B. Specimens **1247 are handled by a trained medical technician or licensed medical professional, id.   §   IX.C.1, at “secure, designated ... sites” equipped to provide proper “collection, security, temporary storage, and shipping” to the laboratory, id.   §   IX.D.1. The person handling the sample is responsible for the integrity of the collection and transfer process, id.   §   IX.D.1, 2, 5, 6, and may not be a supervisor or co-worker of the tested employee, id.   §  IX.C.2. Unless NJ Transit has reason to believe that the donor may adulterate the sample, individual privacy must be permitted during collection.   Id. §  IX.F.1 (listing four circumstances constituting grounds for “reason to believe that an individual may alter or substitute a specimen,” e.g., a previous urine sample that “falls outside the normal temperature range”).   Any direct observation of the donor must be by a person “of the same gender” and requires prior approval by a supervisor.   Id. §  IX.F.2.

 

Two urine samples are obtained from transit police officers at the collection site.   Each sample is then separated into a “primary” and “split” specimen for testing at a laboratory certified under the Department of Health and Human Services' (“DHHS”) Mandatory Guidelines for Federal Workplace Drug Testing Programs.   Id. §  IX.G.1. The first primary specimen is analyzed for marijuana, cocaine, opiates, phencyclidine or amphetamines using “an immunoassay which meets the requirements of the Food and Drug Administration for commercial distribution.”   Id. §  IX.G.2. If this specimen tests positive, the result is confirmed using gas chromatography/mass spectrometry.   Id. §  IX.G.3. The second primary specimen is similarly analyzed for barbiturates, benzodiazepines and methadone. FN1  Id. §  IX.G.4. If either primary specimen*540  tests positive, the employee has 72 hours in which to exercise his or her option to have the split specimen tested by a different DHHS-certified laboratory.   Id. §  IX.G.5.

 

 

FN1. These substances are not listed in the FTA's regulations.   See 49 C.F.R. §  653.31(b).   We presume that they have been approved for testing by the FTA pursuant to 49 C.F.R. §  40.21 and note that plaintiff has not specifically challenged this additional testing by NJ Transit.

 

The Core Policy requires NJ Transit to employ one or more Medical Review Officers (“MRO”).   Id. §  IX.H.1. The MRO must be a licensed physician with knowledge of substance abuse disorders who is able to review and interpret positive test results.  Ibid. Test results are not deemed positive, and may not be disseminated to any person, until they are reviewed and verified by the MRO. Id. §  IX.H.2. In addition to verifying the chain of custody and the reasonableness of the laboratory report, the MRO must “[e]xamine alternate medical explanations for positive drug test results,” and must give each employee “an opportunity to discuss the test results” prior to verifying a positive test.   Id. §  IX.H.2.a-d.

 

The MRO is required to report all verified positive test results to the appropriate management official and to provide copies of the report to the employee.   Id. §  IX.H.2.g. Those positive results that have “a legitimate medical explanation or which are scientifically insufficient for further action” are reported as negative.   Id. §  IX.H.2.e. All negative results are also promptly reported to the employee.   Id. §  IX.H.2.h. Records of testing results are “maintained in a secure location with controlled access” and, pursuant to federal regulation, see 49 C.F.R. 653.71(b), may be kept for only a limited number of years.   Core Policy §  XIII.B. Test results may be released on written request of the employee, to “the decision maker in a lawsuit, grievance, or other proceeding initiated by or on behalf of the employee tested,” to certain federal agencies, “or to a State oversight agency with regulatory authority over NJ TRANSIT.”   Id. §  XIII.A.1-5. Addendum I, in reliance on the Attorney General's Guidelines, further requires transit officers' positive results to “be included in a central registry maintained by the Division of State Police to be accessed only through a court order or as part of a confidential investigation  *541 related to law enforcement employment;  and reported to the county prosecutor.”   Addendum I §  XIII.A.1.

 

The Core Policy includes provisions establishing an employee assistance program (“EAP”) for covered employees who need assistance with use of controlled substances.   **1248 Core Policy §  VIII. Employees may participate in the program on a voluntary basis, id.   §   VIII.B, or may be required to participate if they test positive for drugs and have not previously had a positive drug test, id.   §   VIII.C. The Core Policy provides, however, that transit officers are not eligible for participation in EAP and that a transit officer who tests positive for illegal drugs must be dismissed.   Id. §  VIII.B.3. Thus, a transit officer “cannot avoid[ ] [dismissal] by utilization of the EAP, even on a voluntary basis.”  Ibid. This provision also reflects NJ Transit's interpretation of the requirements of the Attorney General's Guidelines.

 

 

-D-

 

On April 26, 1995, PBA filed a complaint in the Law Division alleging that NJ Transit's random drug and alcohol testing of law enforcement officers represented by PBA Local 304 constituted an illegal search and seizure in violation of Article I, Paragraph 7 of the New Jersey Constitution.   The PBA also sought temporary restraints preventing the Agency from implementing testing as to those officers.   PBA did not challenge pre-employment testing, or testing either conducted at an annual physical exam or based on reasonable individualized suspicion.

 

As a defense, NJ Transit asserted that the Federal Act preempted state action inconsistent with federally required testing programs implemented by state transportation agencies in receipt of federal funding. FN2  The trial court found that preemption did not  *542 apply because NJ Transit is not required to accept federal funding, but concluded that random drug testing of transit police officers was permissible under the New Jersey Constitution.   The court denied PBA's application for a restraining order, and entered judgment upholding the constitutionality of the testing program and dismissing PBA's complaint.

 

 

FN2. NJ Transit based its preemption argument on the provision of the Act that states:

A State or local government may not prescribe, issue, or continue in effect a law, regulation, standard, or order that is inconsistent with regulations prescribed [under the statute, except] a State criminal law that imposes sanctions for reckless conduct leading to loss of life, injury, or damage to property.

[49 U.S.C.A. §  5331(f)(1).]

Because we find that NJ Transit's drug testing program passes constitutional muster, we do not reach the Agency's preemption defense.

 

The Appellate Division affirmed in a unanimous opinion.  290 N.J.Super. 406, 675 A.2d 1180 (1996).   In sustaining NJ Transit's program, the court adopted the special needs balancing test of Skinner v. Railway Labor Executives' Ass'n, 489 U.S. 602, 109 S.Ct. 1402, 103 L.Ed.2d 639 (1989), and National Treasury Employees Union v. Von Raab, 489 U.S. 656, 109 S.Ct. 1384, 103 L.Ed.2d 685 (1989), and rejected the 1987 Appellate Division opinion in Fraternal Order of Police, Newark Lodge No. 12 v. City of Newark, 216 N.J.Super. 461, 524 A.2d 430 (App.Div.1987) (“FOP ”), which had held that random drug testing of Newark police officers violated Article I, Paragraph 7 of the New Jersey Constitution.  290 N.J.Super. at 422, 675 A.2d 1180.   The Appellate Division found that requiring a warrant or individualized suspicion would be impractical, and that the government's interest in preventing the great harm that could occur “ ‘before any signs of impairment become noticeable to supervisors or others' ” outweighed the privacy interests of transit police officers.  Id. at 426, 675 A.2d 1180 (quoting Skinner, supra, 489 U.S. at 628, 109 S.Ct. at 1419, 103 L. Ed.2d at 667).

 

 

II

 

-A-

 

 

Article 1, Paragraph 7 of the New Jersey Constitution states:

 *543 The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated;  and no warrant shall issue except upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched and the papers and things to be seized.

 

Both Article 1, Paragraph 7 and the Fourth Amendment to the United States Constitution, which contain virtually identical language, prohibit unreasonable searches and **1249 seizures by government agents.   See, e.g., Skinner, supra, 489 U.S. at 619, 109 S.Ct. at 1414, 103 L.Ed.2d at 661;  Schmerber v. California, 384 U.S. 757, 768, 86 S.Ct. 1826, 1834, 16 L.Ed.2d 908, 918 (1966);  State v. Pierce, 136 N.J. 184, 208, 642 A.2d 947 (1994).

 

 [1] Plaintiff does not allege that NJ Transit's testing program is an unreasonable search under the Fourth Amendment;  rather, PBA claims that random drug testing of transit police officers is unreasonable under Article 1, Paragraph 7 of the New Jersey Constitution.   Preliminarily we observe that mandatory drug testing is subject to the requirements of both the federal and New Jersey Constitutions.   Case law in the federal courts and in our state has firmly established that any government-compelled drug or alcohol testing is a search.   See Skinner, supra, 489 U.S. at 617, 109 S.Ct. at 1413, 103 L.Ed.2d at 660 (finding that government-compelled drug testing was search subject to Fourth Amendment);  Von Raab, supra, 489 U.S. at 665, 109 S.Ct. at 1390, 103 L.Ed.2d at 701-02 (same);  Rawlings v. Police Dep't of Jersey City, 133 N.J. 182, 188, 627 A.2d 602 (1993) (“A drug test performed pursuant to departmental regulations ... is a search subject to the requirements of the Fourth Amendment.”);  O'Keefe v. Passaic Valley Water Comm'n, 132 N.J. 234, 242, 624 A.2d 578 (1993) (same).   The testing program must, therefore, meet the reasonableness requirement of both the Fourth Amendment and Article 1, Paragraph 7.

 

 

-B-

 

 [2] Generally, under the Fourth Amendment and under Article I, Paragraph 7, searches or seizures conducted without a warrant  *544 based on probable cause are considered per se unreasonable.   See, e.g., Horton v. California, 496 U.S. 128, 133, 110 S.Ct. 2301, 2306, 110 L.Ed.2d 112, 120 (1990) (observing “general rule that warrantless searches are presumptively unreasonable”);  State v. Hempele, 120 N.J. 182, 217, 576 A.2d 793 (1990) ( “The New Jersey Constitution requires the approval of an impartial judicial officer based on probable cause before most searches may be undertaken.   Any warrantless search is prima facie invalid.” (citations and internal quotations omitted)).   The validity of a warrantless search may, however, be established if the government demonstrates that the search falls within one of the recognized exceptions to the warrant requirement.

 

 [3] Traditional exceptions to the warrant requirement have been based on a showing either of probable cause or of reasonable individualized suspicion to believe that the person to be searched has violated the law.   See, e.g., United States v. Ross, 456 U.S. 798, 102 S.Ct. 2157, 72 L.Ed.2d 572 (1982) (permitting search of vehicle when there was probable cause to believe that vehicle contained contraband);  Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968) (permitting police officers to stop suspect based on individualized suspicion that person stopped may have been involved in criminal activity);  State v. Davis, 104 N.J. 490, 505-08, 517 A.2d 859 (1986) (allowing investigatory stop when police officer had particularized suspicion of possible criminal activity by defendant);  State v. Martin, 87 N.J. 561, 567-71, 436 A.2d 96 (1981) (allowing search of automobile when probable cause existed to believe automobile had been used in robbery).   In certain limited circumstances, however, searches conducted without probable cause or reasonable individualized suspicion have been upheld.   See Michigan Dep't of State Police v. Sitz, 496 U.S. 444, 110 S.Ct. 2481, 110 L.Ed.2d 412 (1990) (permitting sobriety checkpoints at which state police stop all car
