These unemployment benefit cases present issues concerning the maintenance of class actions in this State and the authority of the department of employment security (DES) to terminate without prior notice and hearing the benefits of initially eligible claimants who have continued to make weekly filings according to RSA 282:3 A and Regulation 13 (1975). Plaintiff Arthur J. Royer was found initially eligible for unemployment benefits on August 22, 1974, and was disqualified indefinitely for benefits on September 27, 1974. On appeal, the decision of the appeal tribunal on October 30, 1974, upholding the disqualification, was overturned by the Hillsborough County Superior Court (Batchelder, J.) on October 25, 1976. Defendants excepted to the court’s award of eight weeks of benefits and filed an appeal with this court. Subsequently, the benefits were paid and therefore the defendants’ exception is overruled.
*675Mr. Royer, on behalf of himself and the class of others similarly situated, also filed a bill in equity on October 9, 1974, in Hillsborough County Superior Court, seeking a temporary restraining order and a temporary injunction. These prayers were denied by Bois, J. However, a motion to dismiss the class action brought against the State was also denied by Bois, J. The benefit appeal case and the bill in equity seeking a permanent injunction, declaratory relief, and damages where then heard on a consolidated record in the Hillsborough County Superior Court (Batchelder, J.). The trial court allowed the case to proceed as a class action and ruled on statutory and constitutional grounds that unemployment benefits may not be terminated without prior notice and hearing. Defendants’ motion for consideration was denied and all questions of law raised by exceptions were reserved and transferred to this court by Batchelder, J. For the reasons contained herein, we affirm.
I.
The defendants argue that plaintiff Royer’s claim is moot since he has received all unemployment benefits to which he was entitled. Mootness is not subject to rigid rules, but is a matter of convenience and discretion. Proctor v. Butler, 117 N.H. 927, 380 A.2d 673 (1977). Plaintiff raises issues of significant constitutional dimensions; the pressing public interest in those issues and the avoidance of future litigation of the same issues justify a decision on the merits. Martel v. Hancock, 115 N.H. 237, 238, 339 A.2d 9, 10 (1975); O’Neii v. Thomson, 114 N.H. 155, 159, 316 A.2d 168, 171 (1974). Additionally, this case presents issues that are “capable of repetition, yet evading review.” Weinstein v. Bradford, 423 U.S. 147, 148 (1975). The challenged action was too short in duration to be fully litigated prior to its expiration, and although plaintiff is now employed, there is a reasonable expectation that he may again be subjected to the challenged action. Id. at 149. Because of this ruling on mootness, the class action question need not be considered.
II.
The trial court correctly found that the practice of the department violates RSA 282:5 B(9), which provides that “It shall be a condition precedent to the cessation of payment of benefits to any individual that he be given an opportunity to appear in person ... to be heard relative to his continued entitlement to benefits.” Although the statute requires that the commissioner promulgate regulations to carry out its mandate, the department has no written directive *676requiring certifying officers to talk to initially eligible claimants before terminating benefits, and has no standard procedure for notifying initially eligible claimants before termination of benefits that a specific question has arisen concerning their continued receipt of benefits. Plaintiff Royer and another claimant, Elizabeth Becker, received no written notice to inform them that the department questioned their availability for work (one of the conditions for receiving benefits) until they received the decision terminating their benefits. Further, DES’ standard procedure after an initially eligible claimant has been disqualified by a certifying officer is to stop benefits entirely while an appeal is pending before the appeal tribunal. This procedure and its resultant cessation of benefits violate RSA 282:5 B(9). The interview with a certifying officer, which DES provides claimants prior to termination of benefits, does not comport with the requirements of RSA 282:5 B(9), because a claimant receives no prior notice of any specific questions concerning the claimant’s continued entitlement of benefits. Additionally, the existing procedures of DES violate RSA 282:5 B(10) (1977), which requires that unemployment benefits found payable by an administrative determination must continue until the decision of a subsequent appellate body finding that benefits are not payable.
III.
The termination of unemployment benefits without prior notice and hearing also violates the Social Security Act, 42 U.S.C. 503(a)(1) (1970), which requires that the State, to qualify for payment of DES administrative expenses by the federal government, must comply with certain federal requirements. Section 503(a)(1) states that individual State methods of administration must be “reasonably calculated to insure full payment of unemployment compensation when due.” The Supreme Court, in an unemployment compensation case, held that the words “when due” meant the time promptly after an initial determination of eligibility. California Human Resources Dep’t v. Java, 402 U.S. 121 (1971); Pregent v. New Hampshire Dep’t of Empl. Security, 361 F. Supp. 782 (D.N.H. 1973), vacated and remanded for determination of mootness, 417 U.S. 903 (1974).
The department’s procedure of summary termination by a certifying officer, on the grounds of a subsequent finding of ineligibility, does not change the concept of when benefits are due. Pregent, 361 F. Supp. at 793. The average delay of eight weeks between the last check received prior to termination and the issuance of the first check after the appeal tribunal reverses the termination decision is *677not a de minimis deprivation of property and highlights the importance of a pretermination due process hearing.
IV.
The existing procedures for the termination of unemployment benefits also violate the due process clause of the fourteenth amendment to the United States Constitution and part I, article 15 of the New Hampshire Constitution, which provides that no person can be deprived of his liberty or estate but by the judgment of his peers or the “law of the land.” “Law of the land” has been consistently interpreted as meaning due process of law. Petition of Harvey, 108 N.H. 196, 230 A.2d 757 (1967); Opinion of the Justices, 66 N.H. 629, 33 A. 1076 (1891). Unemployment compensation claimants have “the same type of statutorily grounded claim of entitlement to, or property interest in, unemployment compensation benefits that the welfare recipients had in the Goldberg case.” Wheeler v. State, 115 N.H. 347, 341 A.2d 777 (1975), cert. denied, 423 U.S. 1075 (1976). Having found that the plaintiff class has a property interest in the continuation of unemployment compensation benefits, the only question remaining is what procedures are due.
The trial court ruled that DES must provide notice and hearing before termination comporting with the following guidelines:
(a) A hearing need not take the form of a judicial or quasi-judicial trial, but the claimant must be provided with timely and adequate notice detailing the reasons for termination, and an effective opportunity to defend by confronting and cross-examining adverse witnesses and by presenting his own arguments and evidence orally before the decision-maker;
(b) Counsel need not be furnished at the pretermination hearing, but the claimant must be allowed to retain an attorney if he so desires;
(c) The decision-maker need not file a full opinion or make formal findings of fact or conclusions of law, but should state in writing the reasons for his determination and indicate the evidence he relied on;
(d) The decision-maker must be impartial, and he shall not have participated in the investigatory or fact-finding stages of the case or in making the determination under review.
*678The trial court enjoined DES from terminating unemployment benefits without such notice and hearing.
The due process provision of the State constitution requires notice and hearing before deprivation of a property interest. Burgess v. City of Concord, 118 N.H. 579, 391 A.2d 896 (1978); Calawa v. Town of Litchfield, 112 N.H. 263, 296 A.2d 124 (1972). The United States Supreme Court has also set out a balancing test under the due process clause which utilizes three factors:
the private interest that will be affected by the official action . . . the risk of an erroneous determination of such interest through the procedures used, and the probable value, if any, of the additional or substitute safeguards; and finally, the Government’s interest, including the function involved and the fiscal and administrative burdens that the additional or substitute safeguards would entail. Mathews v. Eldridge, 424 U.S. 319, 335 (1976).
The defendants argue that the individual’s interest is not particularly strong, because an unemployment compensation claimant has access to private resources and government assistance. General assistance in New Hampshire is not aided by the federal assistance program, but is instead a system of town and county welfare and might not always fill the financial gap of initially eligible unemployed workers whose benefits have been terminated. The defendants also argue that the benefit entitlement of an unemployment compensation claimant is not based upon financial need, comparable to the social security disability recipient in Mathews, where a pretermination hearing was not required.
The New Hampshire Legislature has established the purpose of the unemployment compensation system as “the attempt to provide for such distress solely through poor relief not only is inadequate for the need but productive of serious social consequences upon many self-respecting persons. ...” Preamble for Unemployment Compensation Law, as inserted by RSA ch. 282 (Supp. 1977) Laws 1977, 441:14. The “distress” to which the legislature referred includes “economic insecurity [which] is a serious menace to the health, morals, and welfare of this state.” The need for unemployment benefits can be critical; welfare benefits and unemployment compensation are used to fulfill the recipients’ needs for the basic necessities of life. Note, Due Process Requirements in Payment and Termination of Unemployment Compensation Benefits, 78 Dick. L. Rev. 572, 578 (1973).
*679To lessen the risk of erroneous deprivation, some form of hearing is usually required when a liberty or property interest is at stake; only rarely has the Supreme Court upheld deprivation without such process. Mathews, 424 U.S. at 333. The fundamental requisite of due process is the opportunity to be heard, and that opportunity is useless unless one is informed of the matter pending and the hearing is granted at a meaningful time and in a meaningful manner. Armstrong v. Manzo, 380 U.S. 545, 550 (1965); Mullane v. Central Hanover Trust Co., 339 U.S. 306, 314 (1950). The Court has even considered the risk of erroneous deprivation of utility service through “necessary reliance on computers,” and held that the risk of error was “not insubstantial.” Memphis Light, Gas & Water Div. v. Craft, 98 S. Ct. 1554, 1565 (1978). There, the Court required that some form of notice and hearing be given prior to the termination of utility service.
The trial court found that decisions of certifying officers terminating benefits of initially eligible claimants are frequently reversed by the appeal tribunal or the superior court. Although DES does afford the claimant a counter-interview and occasionally an interview with a certifying officer, claimants do not necessarily receive notice of a specific question that may have arisen concerning their continued receipt of benefits. Unlike the routine medical reports that were the basis of the termination decision in Mathews, the possible complexity of factual issues in an unemployment benefits case mandates a pretermination evidentiary hearing to improve the accuracy and fairness of DES termination decisions.
The State’s interest is served by providing pretermination notice and hearing, which further provides accuracy and fairness in the unemployment compensation system, and therefore can ease more effectively the economic distress the legislature sought to avoid. Pretermination hearings will probably result in fewer erroneous determinations, and will put money in the hands of unemployed workers to aid them in their search for substantially equivalent employment. See California Dep’t of Human Resources v. Java, 402 U.S. 121, 132 (1971).
Accuracy and fairness are also promoted by affording claimants the opportunity to cross-examine adverse witnesses and to present witnesses and evidence orally. Greene v. McElroy, 360 U.S. 474, 496 (1959). Although the State is not required to provide counsel, the private retention of counsel can be invaluable when a claimant cannot effectively present a sometime complicated factual case *680before the DES. See Duval v. Duval, 114 N.H. 422, 322 A.2d 1 (1974); Bruno, The Right to Counsel in Civil Contempt Cases, 16 N.H.B.J. 126 (1974). Finally, an impartial decision-maker and a written statement of reasons are elements of a fair hearing which are traditional and necessary. Burhoe v. Whaland, 116 N.H. 222, 356 A.2d 658 (1976); Soc'y for Protection of N.H. Forests v. Site Evaluation Committee, 115 N.H. 163, 337 A.2d 778 (1975).
We realize that the required procedures may entail added responsibility and some added cost for the department. However, DES will not lose significant sums in payment to ineligible claimants, because it can recover overpayments by set-off against future benefits or through civil collection actions provided by statute. RSA 282:5 B(10). Excellent percentage rates of recovery have been reported by DES. Also, as the Pregent court stated, “Hearings may be accelerated and additional personnel employed. The Department of Employment Security’s administrative skill in devising prompt procedures for hearings will largely determine the degree of impact on the public fisc.” Pregent, 361 F. Supp. at 793. Although the vindication of due process rights may have an impact on the allocation of scarce administrative resources, the claimant’s legal right cannot turn upon DES’ alleged inability to meet its other obligations. See Caswell v. Califano, 583 F.2d 9 (1st Cir. 1978). The small increase in administrative time and expense which may result from these additional procedures is far outweighed by the strong interest of unemployed claimants in continued receipt of benefits, by the avoidance of the high risk of erroneous decisions under the current system, and by the benefit of the added protection of pretermination notice and hearing.
We hold that part I, article 15, New Hampshire Constitution, requires pretermination hearings satisfying the requirements of this opinion, and until DES develops procedures, it cannot terminate payment of benefits to a claimant. The case is remanded to the trial judge for any further proceeding consistent with this opinion to ensure that the new procedures developed are in compliance with State constitutional mandates.
Exceptions overruled; remanded.
