The opinion of the Court was delivered by
This аppeal presents two issues of first impression: first, whether the Delaware River Port Authority (DRPA) and its employees are subject to the New Jersey Conscientious Employee Protection Act (CEPA); second, if they are not, whether they are subject to the New Jersey common law principle that protects employees from being discharged in violation of a clear mandate of public *590 policy. Because DRPA is a bi-state agency, a unique creature of a federally approved compact between two states, this Court must determine as a threshold matter the proper methodology to apply in resolving when one state can impose obligаtions on a bi-state agency.

Plaintiff Ballinger appeals from grants of summary judgment in favor of defendant DRPA and its individual employees. Accordingly, in reviewing those motions for summary judgment, we must accord plaintiff the benefit of all reasonable inferences that may be drawn from the evidence submitted by the parties.

From April 1984 until February 8, 1995, defendant DRPA employed plaintiff Ralph S. Ballinger as a non-union police officer. In November 1994, Ballinger noticed that pieces of furniture began appearing at the DRPA building where he was assigned to work. He also overheard a conversation between another officer and Captain Alvin Woodhouse, one of Ballinger’s supervisors, concеrning the furniture. According to Ballinger, the officer was laughing and said that there was an old, abandoned RCA building in Camden where a security guard would let him in and “you could just go down and take whatever you wanted.” Ballinger knew that just a few days prior to that discussion DRPA and Camden Police had been called to investigate burglaries and vandalism in the very same building.
Ballinger did not know “how far [up the ranks] this went as far as hearing Captain Woodhouse ask for furniture.” So, when he happened to see a long-time personal and family friend, Captain Bernard Gallagher of the New Jersey State Police, he sought advice from the Captain concerning what if anything he should do. Acting on Captain Gallagher’s suggestion, Ballingеr took photographs of the furniture and sent them along with a letter to Captain Gallagher. By communicating information about the *591 perceived illegal activities 1 in that manner, Ballinger went outside his chain of command as a DRPA police officer and thereby violated DRPA policies and procedures. The DRPA learned about Ballinger’s independent investigation and correspondence with Captain Gallagher. By letter dated February 8, 1995, the DRPA terminated Ballinger for disregarding his chain of command and disclosing information about the DRPA to an outside agency.
In December 1995, Ballinger filed a one-count complaint alleging that the DRPA terminated his employment in violation of CEPA,
N.J.S.A.
34:19-1 to -8. Ballinger later amended that comрlaint to include CEPA claims against DRPA employees Paul Drayton, Vincent Borrelli, Richard Sullivan, Alvin Woodhouse, David McClintock and Alan Daniels, individually. The DRPA and the individual employees filed motions to dismiss for failure to state a claim. The trial court granted the motions on the ground that CEPA does not apply to DRPA or its employees because DRPA cannot be subjected to the unilateral action of any one of its member states’ legislatures. The Appellate Division affirmed, finding that CEPA was not “substantially similar” to Pennsylvania’s Whistleblower Law such that the claim could proceed.

The trial court also denied Ballinger’s cross-motion to file another amended complaint to include common law rеtaliatory discharge claims. The Appellate Division reversed and remanded, instructing the trial court to make “a painstaking comparison of the common laws of New Jersey and Pennsylvania, like the one we engaged in as to CEPA and the Whistleblower Law.”

A.
The threshold question presented in this appeal is the extent to which DRPA, as a bi-state agency, may be subject to New Jersey law. The compact does not mention CEPA; nor does it contain any provision that would expressly allow or preclude the application of CEPA. The compact also is arguably silent concerning whether DRPA may be subject to the common law of either Pennsylvania оr New Jersey and, if so, to what extent.
The State of New Jersey and the Commonwealth of Pennsylvania created the direct predecessor to DRPA, the Delaware River Joint Commission, in 1931. N.J.S.A. 32:3-1 to -18; Pa. Stat. Ann. tit. 36, §§ 3503 to 3509. That interstate compact was approved by the United States Congress in 1932. Pub. Res. 26, ch. 258, 47 Stat. 308 (1932). The Joint Commission was created for the *593 purpose of developing and maintaining interstate transportation routes, namely bridges and port facilities, between the two states. N.J.S.A. 32:3-2; Pa. Stat. Ann. tit. 36, § 3503, art. I. In 1951, New Jersey and Pennsylvania changed the name of the Joint Commission to the Delaware River Port Authority. Id.

Courts applying Pennsylvania law do not necessarily agree with this Court’s holding that “[t]he corollary of the рroposition that neither state may individually impose its will on the bi-state agency is that the agency may be made subject to complementary or parallel state legislation.”

Notwithstanding those state court decisions, the United States District Court for the Eastern District of Pennsylvania recently rejected the theory that one state’s legislation need only be “complementary or parallel” to, or evidence substantially similar public policies as, the other state’s law in order for it to apply to DRPA.

B.
We now address whether DRPA may be subject to the common law and, if so, to what extent. DRPA argues that since neither state may unilaterally impose additional duties on it, such obligations may be imposed only through legislation enacted by both states that expressly includes DRPA. To support that position, DRPA relies on the provision of the compact that states that DRPA “shall also have such additional powers as may hereafter be delegаted to or imposed upon it from time to time by the action of either State concurred in by legislation of the other.” N.J.S.A. 32:3-5; Pa. Stat. Ann. tit. 36, § 3503, art. IV(q) (emphasis added). According to DRPA, because the two states never expressly agreed to the imposition of the common law, DRPA cannot now be subject to the common law absent express legislative consent. We disagree.
Under the compact, DRPA has the power to “sue and be sued.”
N.J.S.A.
32:3-5(b);
Pa. Stat. Ann.
tit. 36, § 3503, art. IV(b). The “sue and be sued” provision “is considered a waiver of sovereign immunity.”

We reject DRPA’s position that the “sue and be sued” clause operates only within the confines of the compact. That is, when
*597
DRPA is the party suing it apparently assumes it may take advantage of expanding common law, but when it is being sued it contends that it may not be subject to common law obligations without express legislative consent.

“Bi-state agencies such as the [DRPA] do not exist in a vacuum.”

The [agency] is not a separate level of government somewhere between the federal government and the contracting states. It is part of the government of each of the states....
... [T]he states did not create a governmental authority and cut the umbilical cord____As the agent of each state, the [agency] is subject to all of its laws, whether of statutory or common law origin, except insofar as the states agreed expressly or by fair implication to place it beyond them.
[State v. Murphy, supra, 36 N.J. at 186,175 A.2d 622 (emphasis added) (requiring agency to produce transcripts in a criminal case, notwithstanding internal agency rule that transcripts were confidential).]
We conclude that the common law can be applied to the extent it fills a void in the compact.

Having determined that the appropriate test to apply in deciding whether the law of one state may be applied to a bi-state agency is whether or not the laws of the two states, either common law or statutory law, are substantially similar, we now must decide whether CEPA is similar to Pennsylvania’s Whistle-blower Law, and whether the two states would allow a common law claim for wrongful discharge on the facts in this record.
A.
In his cross-petition, Ballinger argues that the Appellate Division erred in finding that CEPA is not substantially similar to

Pennsylvania’s Whistleblower Law. In order to be deemed substantially similar, the two laws at issue must “evidence some showing of agreement.”

Most important, however, those differences reflect that the goals of the overriding legislative schemes are different. As the Pennsylvania Supreme Court stated:
[W]e believe that the Whistleblower Law is not primarily designed to punish an employer for harboring retaliatory motives, but is, rather, chiefly a remedial measure intended to “enhance openness in government and compel the government’s compliance with the law by protecting those who inform authorities of wrongdoing.” In enacting the statute, the General Assembly aimed to effectuate such design by ensuring that employees are not discouraged from reporting violations of legal or ethical codes. Additionally, recovery under the statute is proportionate to the harm suffered, as punitive damages are not available. Finally, we are unaware of any authority providing that whistleblower statutes are primarily punitive, rather than remedial, in that their chief purpose is to punish employers for harboring bad motives.
*601 [O’Rourke v. Commonwealth, Dep’t of Corr., 566 Pa. 161,778 A.2d 1194 , 1202-03 (2001) (internal citations omitted).]
In contrast, New Jersey’s legislation is more far-reaching. “The purpose of the CEPA is to ‘protect employees who report illegal or unethical work-place activities.’”

Having determined that CEPA does not apply to DRPA, we also express our agreement with the court in Ballinger I that Ballinger’s ineffective attempt to bring a CEPA claim does not constitute a waiver of common law causes of action. The waiver provision in CEPA provides:
Nothing in this act shall be deemed to diminish the rights, privileges, or remedies of any employee under any other federal or State law or regulation or under any collective bargaining agreement or employment contract; except that the institution of an action in accordance with this act shall be deemed a waiver of the rights and remedies available under any other contract, collective bargaining agreement, State law, rale or regulation or under the common law.
[NJ.S.A 34:19-8.]
This Court previously has decided that the waiver provision does not prohibit a plaintiff from also asserting a common law claim that is distinct from the CEPA claim.

An overview of the duties and responsibilities incumbent on a DRPA police officer is helpful in understanding the issue presented. In 1957, New Jersey and Pennsylvania each passed legislation permitting the DRPA to appoint police officers to maintain “safety and preserve order” on DRPA bridges and tunnels. See N.J.S.A 32:4-6; Pa. Stat. Ann. tit. 36, § 3504.1. Initially, that legislation provided that DRPA police officers acting on DRPA property “shall have the power and authority to make arrests for any crimes, misdemeanors, and the offenses committed under the laws of’ either New Jersey or Pennsylvania. Id. The legislation further provided that the DRPA may administer to such police officers “an oath or affirmation faithfully to perform the duties of their respective positions or offices.” Id.
A number of years later, in 1986 and 1994 respectively, New Jersey and Pennsylvania adopted legislation to confer full police power on DRPA police acting on non-DRPA property. L. 1986, c. 209; 1994 Pa. Laws 792, No. 110. That legislation provides that DRPA police offiсers acting in “any other areas of the port district ... shall have all of the powers, including the right to carry firearms while on duty, and all of the immunities conferred by law on police officers or municipal police officers in the enforcement of the laws of’ either New Jersey or Pennsylvania. Id. (codified at N.J.S.A. 32:4-6; Pa. Stat. Ann. tit. 36, § 3504.1); accord Senate Independent Authorities Committee, State of New Jersey, Statement to S. Bill 2287 (Sept. 15, 1986) (stating “The bill ... confers on DRPA police officers acting within the port district all of the powers and immunities enjoyed by other police officers in New Jersey and Pennsylvania.”); Remarks of Pennsylvania Senator Salvatore on Senate Passage, June 14, 1994, S.B. 1751, 1994 Pa. *604 Legis. J. 2308 (stating that the legislation afforded DRPA police officers full police powers on DRPA property as well as “those police powers, privileges and immunities as the laws of [Pennsylvania or New Jersey] confer upon municipal police officers while beyond the territorial limits of their primary jurisdiction.”). Thus, it is clear that under the compact, DRPA police officers are required and are expected to function as would other police officers in either New Jersey or Pennsylvania.
In both New Jersey and in Pennsylvania, “[t]he fundamental duty of a policeman ... is to be on the lookout for infractions of the law and to use due diligence in discovering and reporting them.”

We next address whether the public policy alleged here to have been breached, wrongful retaliation against a law enforcement officer for reporting suspected criminal activity, is a “clear mandate of public policy” that would be actionable in both states. Given that both states look to the same sources for public policy,
*606
the aрpropriate question becomes whether there is a “dominant theme that appears from our legislation and case law?”
Bunk, supra,
144
N.J.
at 191,
In dismissing Ballinger’s common law claim, however, the trial court stated:
[Counsel] mentioned the dominant theme and the Whistleblower statute in Pennsylvania and the CEPA statute in New Jersey. Both have the same dominant theme. If that were the test, then that would be all that is necessary to determine whether or not each state has a dominant theme оr a public policy to advance. It’s something like nobody’s against Mom and apple pie. But that’s not what the Appellate Division said in this case. They did a comparison of the statutory language in the Pennsylvania’s Whistleblower statute and a comparison to — to the New Jersey CEPA statute and I think that’s what I’m required to do here without regard to the dominant theme because everybody agrees as to the value of a dominant theme.
We agree with the Appellate Division that the trial court “took a too restrictive view of both the Pennsylvania common law and [the Appellate Division] directive.”
Where there is a dominant theme that clearly appears in the common laws of the creator states, failure to apply those laws “would be the failure to apply so important a policy to an entity created by both states for their mutual benefit.”

Nonetheless, DRPA claims that the facts of this case would not support a cause of action in Pennsylvania. DRPA argues that Pennsylvania does not have a public policy claim for “whistle blowing” and cites a number of cases in support of that proposition. Those cases, however, are distinguishable. First, the cases involve civilians, not police officers, who had no statutory duty to “blow the whistle.” See

Finally, the individual defendants argue that, because they were not acting outside the scope of their employment, they cannot be individually liable to plaintiff for wrongful discharge. “Whether an employee is or is not acting within the scope of his or her employment, ... is only relevant in determining whether the employer can be secondarily liable for the employee’s tort. In either case, the. employee himself [or herself] remains liable for his [or her] own torts.”

That conclusion comports with the long-standing rule that “[a]n agent who does an act otherwise a tort is not relieved from liability by the fact that he acted at the command of the principal or on account of the principal.”

Notes
No criminal charges relating to the furniture ever were filed by the State Police. According to DRPA Investigator David J. McClintock, some form of agreement had been reached in the fall of 1994 between the Camden Redevelopment Agency and DRPA. That agreement purportedly allowed certain DRPA employees to take items from the closed RCA building. Ballinger was unaware of that agreement; notice of it apparently was not given to all DRPA employees.
