Defendant was stopped on 23 March 1996 for passing another vehicle in a no-passing zone and was subsequently arrested for dri *621 ving while impaired (DWI) in violation of N.C.G.S. § 20-138.1. He was taken to the magistrate’s office, where the charging officer recorded that defendant willfully refused to submit to an Intoxilyzer breath-alcohol test. Defendant’s refusal was reported to the Division of Motor Vehicles (DMV), which notified defendant that his driver’s license was being revoked for one year, pursuant to N.C.G.S. § 16.2(d). Defendant appealed for a hearing before DMV, at which time the revocation was upheld. He then appealed to civil superior court, and on 17 April 1996, Superior Court Judge David Q. LaBarre overturned the revocation upon finding that defendant did not willfully refuse to submit to the Intoxilyzer test.
Defendant was found guilty of DWI in criminal district court on 7 October 1996 and appealed to superior court for a trial de novo. The trial court denied his motion in limine to exclude evidence relating to his alleged refusal to submit to the breath-alcohol test. Defendant was tried before a jury at the 7 October 1997 Criminal Session of Superior Court, Durham County. The jury found defendant guilty of DWI, and he appealed to the Court of Appeals.
The Court of Appeals issued a unanimous decision granting defendant a new trial. The court held the doctrine of collateral estoppel prevented relitigation of the question of whether defendant willfully refused to submit to an Intoxilyzer test because that issue had been conclusively decided on appeal to civil superior court from defendant’s driver’s license revocation by DMV.
State v. Summers,
The question of whether defendant did, in fact, willfully refuse to submit to an Intoxilyzer test is irrelevant to the determination of this appeal. The only issue before this Court is whether a civil superior court determination, on appeal from an administrative hearing, pursuant to N.C.G.S. § 20-16.2(e), regarding an allegation of willful refusal, estops the relitigation of that same issue in a defendant’s criminal prosecution for DWI.
Under North Carolina law, “[a]ny person who drives a vehicle on a highway or public vehicular area thereby gives consent to a chemical analysis if charged with an implied-consent offense,” which includes an offense involving impaired driving. N.C.G.S. § 20-16.2(a) (1999). If an individual charged with an implied-consent offense willfully refuses to submit to chemical analysis, after being informed of *622 the consequences of willful refusal, in accord with N.C.G.S. § 20-16.2, the charging officer must execute an affidavit to that effect, pursuant to N.C.G.S. § 20-16.2(c). Upon receipt of the affidavit, DMV must expeditiously notify the person charged that his or her license to drive is revoked for twelve months. N.C.G.S. § 20-16.2(d). The person charged may request a hearing by a DMV hearing officer, pursuant to N.C.G.S. § 20-16.2(d), and, if the revocation is sustained, he or she has the right to a hearing de novo in superior court. N.C.G.S. § 20-16.2(e).
In the case sub judice, DMV revoked defendant’s license on the basis of an alleged willful refusal to submit to an Intoxilyzer test. Defendant’s revocation was sustained through all stages of administrative review, and defendant filed a petition for a hearing de novo in superior court. At the civil court hearing, with the State Attorney General’s office representing DMV, Judge LaBarre made findings of fact supporting the conclusion of law that defendant “did not willfully refuse to submit to a chemical analysis upon the request of the charging officer” and, on that basis, dismissed the revocation order. The State did not appeal the trial court’s ruling, which accordingly became the law of the case. This Court must now determine whether the trial court’s ruling became conclusive in defendant’s criminal trial for DWI.
The companion doctrines of res judicata and collateral estoppel have been developed by the courts of our legal system during their march down the corridors of time to serve the present-day dual purpose of protecting litigants from the burden of relitigating previously decided matters and of promoting judicial economy by preventing needless litigation.
Thomas M. McInnis & Assocs. v. Hall,
“when there has been a final judgment or decree, necessarily determining [the] fact, question or right in issue, rendered by a court of record and of competent jurisdiction, and there is a later suit involving an issue as to the identical fact, question or right theretofore determined, and involving identical parties or parties in privity with a party or parties to the prior suit.”
King v. Grindstaff,
The requirements for the identity of issues to which collateral estoppel may be applied have been established by this Court as follows: (1) the issues must be the same as those involved in the prior action, (2) the issues must have been raised and actually litigated in the prior action, (3) the issues must have been material and relevant to the disposition of the prior action, and (4) the determination of the issu'es in the prior action must have been necessary and essential to the resulting judgment.

Unlike issue identity, the rules for determining whether the parties in question are or were in privity with parties in the prior action are hot as well defined. Except in cases where the parties in each claim are identical, the meaning of “privity” for the purpose of collateral estoppel is “somewhat elusive . . . [and] ‘[t]here is no definition of the word “privity” which can be applied in all cases.’ ”
Hales v. N.C. Ins. Guar. Ass’n,
This Court previously determined the question of privity between an attorney general in a civil action and a district attorney in a criminal action in
State ex rel. Lewis v. Lewis,
In the instant case, the State contends the district attorney, representing the State in defendant’s criminal prosecution for DWI, was not in privity with the Attorney General, representing the State in defendant’s appeal to civil superior court from his license revocation. However, there can be no question that the district attorney and the Attorney General both represent the interests of the people of North Carolina, regardless of whether it be the district attorney in a criminal trial court or the Attorney General in a civil or criminal appeal. See N.C.G.S. § 114-2(1), (2), (4) (1999); N.C.G.S. § 7A-61 (1999);
Simeon v. Hardin,
The State also contends the Attorney General’s interest in the revocation proceeding, “to remove from the highway one who is a potential danger to himself and other travelers,”
State v. Carlisle,
*625 Finally, the State argues that even if the requirements for collateral estoppel are met, the application of the judicially created doctrine in this case is inconsistent with the legislative intent to independently regulate DWI prosecution and driver’s license revocation. The State contends the General Assembly could not have intended the outcome of one to offset the admissibility of evidence in the other. However, a review of the statutory language of sections 20-16.2 and 20-139.1, the primary sections prescribing the procedures for conducting chemical analysis and the civil and criminal consequences of the analysis, indicates a commonality of purpose and reflects direct cross-reference and reliance between the two. Section 20-16.2 requires that an individual obtaining blood samples for analysis meet the qualification outlined in section 20-139.1, and that a person requesting administration of a chemical analysis of his or her breath be given chemical analysis in accordance with the procedures of section 20-139.1(b). N.C.G.S. § 20-16.2(b), (i). Likewise, section 20-139.1 specifically states that a chemical analysis performed by an arresting officer or by a charging officer under the terms of section 20-16.2 is not valid unless it is performed in accordance with the provisions of section 20-139.1(b). N.C.G.S. § 20-139.1(b) (1999). Section 20-139.1(b3) also establishes the need for sequential breath tests in chemical analysis and provides that a person’s willful refusal to give sequential breath samples constitutes a willful refusal under section 20-16.2. N.C.G.S. § 20-139.1(b3). These are only a few of the reciprocal references outlined in sections 20-16.2 and 20-139.1; however, they establish the State’s common interest, from both a civil and criminal perspective, in the proper administration of chemical analysis and in the outcome of that analysis.
In appealing from the opinion of the Court of Appeals, the State urges this Court to reinstate the precedent established in
Joyner v. Garrett,
“It is well established that the same motor vehicle operation may give rise to two separate and distinct proceedings. One is a civil and administrative licensing procedure instituted by the Director of Motor Vehicles to determine whether a person’s privilege to drive is revoked. The other is a criminal action instituted in the appropriate court to determine whether a crime has been committed. Each action proceeds independently of the other, and the outcome of one is of no consequence to the other.”

In the case
sub judice,
all of the elements of collateral estoppel were satisfied: the interests of the State were represented in the civil appeal by the Attorney General, the district attorney is in privity with the Attorney General, and the issue in interest between the Attorney General in the civil action and the district attorney in the criminal action was material and relevant to the disposition of the civil action and was fully litigated. Therefore, we affirm the Court of Appeals’ holding that the State was collaterally estopped from relitigating the issue of willful refusal when the prior court had determined as a matter of law that a refusal, in fact, did not exist.
Summers,
AFFIRMED.
