OPINION
By the Court,
Mowbray, J.;This is an appeal from a judgment of the district court declaring unconstitutional certain 1973 amendments to the Nevada Industrial Insurance Act.
*117During the 1973 Legislature, Assembly Bill No. 339 was enacted as chapter 762, Stats. Nev. 1973, at 1595-1598. This statute amended the Nevada Industrial Insurance Act, chapter 616 of NRS. Among other things, the amendment provided for the incorporation of the Nevada Administrative Procedure Act (ch. 233B of NRS) into the Nevada Industrial Insurance Act and for the establishment of an Appeals Officer, appointed by the Governor, to conduct administrative hearings in contested claims. The amendment also provided that a decision of the Appeals Officer was to constitute a “final decision” under the Nevada Administrative Procedure Act and that the record for purposes of judicial review of the decision of the Appeals Officer was limited solely to the evidence received during the hearing before the Appeals Officer. Section 6 of chapter 762 provided that no judicial proceedings could be instituted for the recovery of compensation for injury or death under the Nevada Industrial Insurance Act unless a claim for compensation had been filed in accordance with the provisions of NRS 616.500 and there had been a final decision rendered by the NIC Appeals Officer on such claim. Additionally, section 6 provided that judicial proceedings instituted by a dissatisfied claimant after a final decision would be limited to the scope of judicial review of an administrative decision, pursuant to the Nevada Administrative Procedure Act, sections 233B.ISO-23 3B. 150. As a result, the decision of the NIC Appeals Officer was afforded the same status as a decision of an administrative agency under the Nevada Administrative Procedure Act. NRS 233B.140, subsections 4 and 5.1
The respondents, Luther Reese, Daniel G. Mahoney, and Michael E. Ausich, as dissatisfied claimants of benefits under the Nevada Industrial Insurance Act, commenced this original action in the Second Judicial District Court to challenge the constitutionality of the 1973 amendments to the Nevada Industrial Insurance Act. Appellant Richard Bortolin, in his official capacity as the NIC Appeals Officer, was named a party defendant, along with the NIC and the Commissioners, in their official capacities. The district judge, in his amended judgment filed April 22, 1974, ruled sections 4, 5, 6, 7, 8, 9, and 12 of *118chapter 762 unconstitutional because they violated article 6, section 1, of the Nevada Constitution.2
Respondents predicate their argument that the amendments to the Industrial Insurance Act are unconstitutional on the principal ground that they violate the traditional separation of powers doctrine, article 3, section 1, of the Nevada Constitution3 and the judicial power provision set forth in article 6, section 1, of the Constitution.4
In 1880, the Supreme Court of the United States declared in Kilbourn v. Thompson, 103 U.S. 168, 190, 191, that all powers entrusted to government are divided into executive, legislative, and judicial branches, and that it is essential to the successful working of this system that the persons entrusted with power in any one of these branches shall not be permitted to encroach upon the powers confided to the others, but that each shall by the law of its creation be limited to the exercise of the powers appropriate to its own department and no other. The pronouncement was predicated upon reasoning stemming from Plato and Locke. The basic doctrine had been stated by Blackstone a century before Kilbourn, in 1765:
*119“In all tyrannical governments, the supreme magistracy, or the right of both making and of enforcing the laws, is vested in one and the same man, or one and the same body of men; and wherever these two powers are united together, there can be no public liberty. ...” 1 Blackstone Commentaries on the Laws of England 146 (Lewis’s ed. 1902 at 133).
Most state constitutions, as the Nevada Constitution, contain explicit provisions having something in common with the Kilbourn statement. Nev.Const. art. 3, § 1, supra.
The Federal Constitution, however, contains no specific provision that the three kinds of power shall be kept separate. It goes no further than to provide separately for each of the three branches of Government: “All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.” Art. I, § 1. “The executive Power shall be vested in a President of the United States of America. . . .” Art. II, § 1. “The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish. . . .” Art. Ill, § 1.
The Supreme Court of the United States has held that judicial powers may be conferred upon administrative agencies. See Sunshine Anthracite Coal Co. v. Adkins, 310 U.S. 381 (1940); Reconstruction Fin. Corp. v. Bankers Trust Co., 318 U.S. 163 (1943). The High Court, without disapproval, said of the Federal Trade Commission, in 1935: “To the extent that it exercises any executive function — as distinguished from executive power in the constitutional sense — it does so in the discharge and effectuation of its quasi-legislative or quasi-judicial powers, or as an agency of the legislative or judicial departments of the government.” (Footnote omitted.) Humphrey’s Executor v. United States, 295 U.S. 602, 628 (1935).5 *120Since a typical administrative agency exercises many types of power, including executive, legislative, and judicial, a strict application of the theory of separation of powers would make the very existence of such an agency unconstitutional.
While an administrative officer such as the NIC Appeals Officer cannot validly exercise purely judicial functions under article 6, section 1, or article 3, section 1, of the Nevada Constitution, we have heretofore recognized a distinction between purely judicial acts and quasi-judicial administrative acts. As a result, administrative officials can exercise administrative powers which are quasi-judicial in nature without violating the separation of powers doctrine. Provenzano v. Long, 64 Nev. 412, 427, 183 P.2d 639, 646 (1947). The NIC Appeals Officer’s authority is limited to the power to' conduct administrative hearings and make findings and render administrative decisions thereon. To execute these duties, it is necessary to exericse quasi-judicial powers. In Ormsby County v. Kearney, 37 Nev. 314, 346, 142 P. 803, 808 (1914), this court held that a statute which invests an administrative commission or official with administrative powers does not violate the separation of powers clause of the State Constitution, even though some of the administrative powers exercised by the official are quasi-judicial in nature. The statute upheld in Kearney created the office of State Water Engineer and empowered that official to conduct hearings, take evidence, and make decisions that determined water rights. The exercise of these quasi-judicial administrative powers by the State Water Engineer was held not violative of either article 3, section 1, or article 6, section 1, of the Nevada Constitution. The court in Kearney, in upholding the statute against an attack based on the separation of powers clause, quoted from an earlier case, Sawyer v. Dooley, 21 Nev. 390, 396, 32 P. 437, 439 (1893): “It would be impossible to administer the state government were the officers not permitted and required, in many instances, to discharge duties in their nature judicial, in that they must exercise judgment and discretion in determining the facts concerning which they are called upon to act, and in construing the laws applicable to them.”
Kearney is persuasive authority for upholding the constitutional validity of the office of the NIC Appeals Officer. In both cases the statutes challenged had created an administrative position and delegated to the official in that position the power to carry out administrative duties that are quasi-judicial in nature. The duties of both officials are almost identical in that, like the State Water Engineer, the NIC Appeals Officer is granted the power to conduct hearings on contested claims, *121take evidence relevant to those claims, and render final administrative decisions thereon. See also, Humboldt Land & Cattle Co. v. Sixth Judicial Dist. Court, 47 Nev. 396, 224 P. 612 (1924). In Mallatt v. Luihn, 294 P.2d 871 (Ore. 1956), the court considered the question of a legislative delegation of power which allegedly constituted a violation of the doctrine of separation of powers. The court stated, at 880: “. . . [T]he mere fact that some functions usually performed by courts are conferred upon an administrative body does not necessarily bring the legislation into conflict with the principle of the separation of powers.” And in Mulhearn v. Federal Shipbuilding & Dry Dock Co., 66 A.2d 726, 731 (N.J. 1949), the Supreme Court of New Jersey ruled that the State Division of Workmen’s Compensation was not a court, but was an administrative tribunal in a department that was a component part of the State executive department. In addition, the court made a distinction between administrative quasi-judicial duties of an official of the executive branch of government and purely judicial adjudication properly vested in the judicial branch of government. The court stated, at 730:
“The failure to comprehend that administrative adjudication is not judicial springs from the erroneous notion that all adjudication is judicial. This is not so and never has been so. . . . Once the obvious right of the Governor and the Legislature, each to adjudicate within his or its own proper sphere, is recognized and it is conceded that the courts are not the exclusive instrumentalities for adjudication, the true nature of the administrative adjudications, commonly termed ‘quasi-judicial’, becomes apparent. This term serves to characterize not the quality of the adjudication but its origin outside the judicial branch of the government.”6
*122We conclude, therefore, that the NIC Appeals Officer can exercise his administrative powers that are quasi-judicial in nature without violating the separation of powers doctrine. In doing so, we agree with the pronouncement of Mr. Justice Douglas in Sunshine Anthracite Coal Co. v. Adkins, supra, 310 U.S. 381, wherein an administrative agency was empowered by Congress to make a finding of fact whether a coal producer produced bituminous coal as defined in the Bituminous Coal Act. Justice Douglas wrote, at 400: “To hold that there was [an invalid delegation of judicial power] would be to turn back the clock on at least a half century of administrative law.”
The respondents have relied heavily upon State ex rel. Brown v. Nevada Indus. Comm’n, 40 Nev. 220, 161 P. 516 (1916); Dahlquist v. Nevada Indus. Comm’n, 46 Nev. 107, 206 P. 197, 207 P. 1104 (1922); and Nevada Indus. Comm’n v. Strange, 84 Nev. 153, 437 P.2d 873 (1968), in support of their position that this court has by the holdings in those cases established the rule that an aggrieved employee who is dissatisfied with the award granted by the NIC has a right to bring an original common law action in the district court against the Commission.
Brown recognized such a right. Although the Industrial Insurance Act as it then existed created new rights, it did not restrict the employee’s privilege to pursue his common law remedy. Therefore, the court properly recognized his right to sue the Commission. “If a statute which creates a right does not indicate expressly the remedy, one is implied, and resort may be had to the common law, or the general method of obtaining relief which has displaced or supplemented the common law.” (Footnote omitted.) 2A Sutherland Statutory Construction, § 55.03, at 383 (C.Sands 4th ed. 1973). Dahlquist reaffirmed Brown. Since the Legislature had not negated the employee’s right to pursue his common law remedy after the decision in Brown, the court properly followed its prior decision. Strange, supra, decided in 1968, again reaffirmed Brown and Dahlquist, and although an amendment to the Administrative Procedure Act containing the present provisions for judicial review had been passed by the 1967 Legislature, the court *123did not mention it or indicate that it was in any way applicable to the case. The reason for this was simply that the 1967 amendatory act stated, in section 13: “The provisions of this act do not apply to contested cases pending on July 1, 1967.” Stats. Nev. 1967, ch. 280, § 13, at 807, 811. As indicated in the opinion, 84 Nev. at 159, 437 P.2d at 877, Strange was a contested case pending on July 1, 1967; hence, the amendment to the Administrative Procedure Act containing the provisions for judicial review that in the present case were held invalid in the district court did not apply to that case. Actually, the judicial review provisions have been applicable to all agencies of the executive department since 1967, except those agencies expressly exempted. The NIC was not exempted. See NRS 233B.030. We interpret the adoption by reference of the Administrative Procedure Act by the 1973 Legislature as a reaffirmation of the legislative intent to abolish the independent common law action.
Just as the Legislature under the police power could and did abolish the old common law cause of action against the employer and abolish the latter’s defenses and merge both into a comprehensive statutory system which provided a fixed and certain indemnity when the Nevada Industrial Insurance Act was first enacted, so, now, the Legislature can abolish the independent, original cause of action against the NIC. It is settled by a host of authorities that no person has a vested right in a rule of law, nor can anyone assert a vested right in any particular mode of procedure. The legislative mandate is unrestricted, subject, of course, to constitutional limitations. Vineyard Land & Stock Co. v. District Court, 42 Nev. 1, 171 P. 166 (1918); Humboldt Land & Cattle Co. v. Sixth Judicial Dist. Court, supra; Deibeikis v. Link-Belt Co., 104 N.E. 211 (Ill. 1914); Hunter v. Colfax Consol. Coal Co., 154 N.W. 1037 (Iowa 1915); State ex rel. Davis-Smith Co. v. Clausen, 117 P. 1101 (Wash. 1911); Zancanelli v. Central Coal & Coke Co., 173 P. 981 (Wyo. 1918); Munn v. Illinois, 94 U.S. 113 (1876).
We turn to consider the final reason given by the district judge in declaring the aforementioned amendments to the Nevada Industrial Insurance Act unconstitutional: “Said sections of Chapter 762 illegally gave a right to appeal decisions of an appeals officer in workmens compensation cases when such an appeal can legally lie only from a constitutional court or tribunal in such cases.” We find this contention completely meritless.
*124The district judge, in condemning chapter 762 on this ground, predicated his reasoning on dicta appearing in Ormsby County v. Kearney, supra, 37 Nev. at 356, 142 P. at 812, where Chief Justice Talbot declared in his separate, concurring opinion: “As the constitution limits the judicial power in this state to the supreme court, district, justice, city, and municipal courts, it follows that it does not provide for an appeal to the district court from the decision of any tribunal not mentioned in that document.” Justice Talbot’s dictum, however, overlooked that provision of our Constitution that vests district courts with “final appellate jurisdiction in cases arising in justice courts, and such other inferior tribunals as may be established by law.” Nev. Const, art. 6, § 6. In accordance with this constitutional mandate, this court has repeatedly affirmed the district court’s power to entertain appeals from administrative agency hearings and rulings, despite the fact that such agencies are not mentioned in the Constitution. Moreover, we have outlined the scope of judicial review in such cases.7
Although we have not heretofore directly examined the review provisions of the Administrative Procedure Act, we have, on two occasions, implicitly recognized and affirmed the power of the district court to entertain appeals from administrative agencies under the provisions of that Act. In Harrison v. Department of Highways, 87 Nev. 183, 484 P.2d 716 (1971), we noted that NRS 233B.140 affords the court a limited power to modify or reverse agency decisions. In Mead v. State Dep’t of Health, 91 Nev. 152, 532 P.2d 611 (1975), we implicitly affirmed the review provisions of NRS 233B.140 by holding that governmental entities were not “persons” within the meaning of the Act so that such entities could prosecute appeals to the district court. We now make explicit our approval of the review provisions of the Administrative *125Procedure Act. Turning to those provisions, we note that NRS 233B.140(2)8 provides in substance that within 30 days after the service of the petition for review, or within further time allowed by the district court, the Appeals Officer shall transmit to the district court the original or a certified copy of the entire record of the proceedings under review. If, before the date set for the hearing, application is made to the district court for leave to present additional evidence, the court may order such evidence presented to the Appeals Officer. NRS 233B. 140(3).9 The review shall be confined to the record; however, in case of alleged irregularities in procedures before the Appeals Officer not shown in the record, proof thereon may be taken in the district court. NRS 233B.140(4).10 While the district court may not substitute its judgment for that of the Appeals Officer as to the weight of the evidence on questions of fact, the district court may affirm the decision of the Appeals Officer, remand for further proceedings, or reverse or modify the decision if substantial rights of the appellant have been prejudiced because the Appeals Officer’s findings, inferences, conclusions, or decisions are (a) in violation of constitutional or statutory provisions, (b) in excess of statutory authority, (c) made upon unlawful procedure, (d) affected by other error *126of law, (e) clearly erroneous in view of the reliable, probative, and substantial evidence on the record, or (f) arbitrary or capricious or characterized by abuse of discretion. NRS 233B.-140C5).11
Thus we see that relief from a decision of the Appeals Officer is clearly provided for under the Administrative Procedure Act and that the district court is given very broad supervisory powers to insure that all relevant evidence is examined and considered by the Appeals Officer. His findings and ultimate decisions, however, are not to be disturbed unless clearly erroneous or otherwise amount to an abuse of discretion.
When the Nevada Industrial Insurance Act was first enacted in 1913, it represented an entirely new approach to the recovery of compensation by an employee injured or killed on the job. The old procedure of filing suit against an employer who had accepted the terms of the Act was abolished, and recovery by an employee under the terms of the Act was made his exclusive remedy against the employer. NRS 616.270(3); NRS 616.370(1); cf. Cummings v. United Resort Hotels, Inc., 85 Nev. 23, 449 P.2d 245 (1969); McColl v. Scherer, 73 Nev. 226, 315 P.2d 807 (1957), citing both NRS 616.270 and NRS 616.370 and recognizing that recovery under the Industrial Insurance Act is the exclusive remedy of the employee against his employer if his employer has accepted the terms of the Industrial Insurance Act. In response to this departure from the prior procedure, there was concern that the Act was in violation of the Nevada Constitution and therefore “unconstitutional”. The Act, however, was upheld by this court as a valid exercise of the State’s police power. Nevada Indus. Comm’n v. Washoe County, 41 Nev. 437, 446, 171 P. 511, 513 (1918).
*127The 1973 Nevada Legislature amended the Industrial Insurance Act by chapter 762 to create the administrative position of NIC Appeals Officer. This amendment empowered that official to conduct administrative hearings on contested workmen’s compensation claims and delegated quasi-judicial administrative powers to the Appeals Officer so that he could properly carry out his administrative duties. In addition, it abolished the old procedure of filing an independent suit against the NIC if a claimant was dissatisfied with the NIC’s award of compensation by providing that judicial review of the administrative decisions of the Appeals Officer was limited to the scope of judicial review of other administrative decisions under the Nevada Administrative Procedure Act.
We would do well to recall the approach that this court has taken with respect to allegations that a particular statutory change is unconstitutional. Mr. Justice Coleman, in Vineyard Land & Stock Co. v. District Court, supra, 42 Nev. at 26-27, 171 P. at 172-173, set forth the proper guidelines when he wrote:
“We do not accept radical changes without protest. If a statute radically different from anything to which we have been accustomed is enacted, the average lawyer becomes alarmed and at once brands it as unconstitutional. Lawyers generally were very much excited and alarmed when the statutes of the various states creating railroad commissions, corporation commissions, industrial insurance commissions, and the like, were enacted. They considered them not only unconstitutional but revolutionary. Lawyers do not feel that way about the matter today, because they have become used to such statutes. . . .
“We are too prone to view legislation as unconstitutional, unmindful of the fact that, unless a statute violates the letter or spirit of some portion of the constitution, it should be upheld. ...
“ . . These hidebound constructions are unnecessary, and they imperil the existence of constitutional government. The constitutional guarantees must be maintained; but the only way to maintain them is to mold them to the requirements of modern civilization. They must be reins to guide the chariot of progress in the road of safety, not barriers across its track.’ ”
We conclude that the provisions of chapter 762 amending the Nevada Industrial Insurance Act do not violate the Nevada Constitution. Therefore, the judgment of the district court was erroneous as a matter of law, and it is reversed.
Thompson, J., concurs. *128Batjer, C. J., with whom Zenoff, J., joins,concurring:
We agree that the judgment of the district court was erroneous as a matter of law and must be reversed, but for an entirely different reason than those announced by Justice Mowbray, with whom Justice Thompson concurs.
We perceive no valid constitutional question to be decided. Proceedings instituted under the provisions of Nevada Industrial Insurance Act, hereafter referred to as N.I.I.A., are not in reality a lawsuit, but special proceedings essentially contractual in character, sanctioned and encouraged by statute, but not compulsorily imposed on the parties. An employer may elect to accept the terms of the N.I.I.A., by giving notice and paying to the Nevada Industrial Commission all premiums. NRS 616.305.1 The employee, where the employer has made the election pursuant to NRS 616.305, is deemed by implication to have accepted the statutory provisions of the N.I.I.A. at the time of injury for which liability is claimed if he does not give notice to the employer of an election to reject the statutory terms. NRS 616.305. The respondents in this case and their employers were free to decline to adopt the terms of the N.I.I.A. to govern their relationship, and instead be governed by such rights and remedies as might be accorded them under the common law with its constitutional and statutory modifications. See Hecht v. Parkinson, 70 So.2d 505 (Fla. 1954); McNeese Construction Company v. Harris, 273 S.W.2d *129355 (Ky. 1954); Fougnie v. Wilbert & Schreeb Coal Co., 286 P. 396 (Kan. 1930); Sollitt Construction Company v. Walker, 135 N.E.2d 623 (Ind.App. 1956); Grice v. Suwannee Lumber Manufacturing Company, 113 So.2d 742 (Fla.App. 1959). Cf. Reliford v. Eastern Coal Corporation, 149 F.Supp. 778 (E.D. Ky. 1957).
The Supreme Court of the United States, in determining whether the Wisconsin Workmen’s Compensation Act deprived the employer of equal protection of the law in violation of the 14th Amendment of the United States Constitution, held that the employer “having elected to accept the provisions of the law, and such benefits and immunities as it gives, may not escape its burdens by asserting that it is unconstitutional. The election is a waiver and estops such complaint.” Booth Fisheries Co. v. Industrial Comm., 271 U.S. 208, 211 (1926), citing Daniels v. Tearney, 102 U.S. 415 (1880), and Grand Rapids & I. R. Co. v. Osborn, 193 U.S. 17 (1904).
The same reasoning would apply by analogy to the contentions raised by respondents in this case that certain amendments to the N.I.I.A. found in 1973 Statutes of Nevada, Chapter 762, are unconstitutional.2 Likewise it is apparent that the district court erred when it ruled sections 4, 5, 6, 7, 8, 9 and 12 of the above mentioned Chapter 762 to be unconstitutional upon the grounds they violated article 6, section 1 of the Nevada Constitution.
The former procedure of filing a claim for industrial insurance compensation and, if dissatisfied, thereafter filing an original action with another full evidentiary hearing in the district court against the NIC was replaced with the administrative hearing before the Appeals Officer.
The amended judgment provided in part as follows:
“That Sections 4, 5, 6, 7, 8, 9, and 12 of (Chapter 762 of 1973 Statutes of Nevada, pp 1595 through 1598) are unconstitutional, void and ineffective and in violation of Section 1, Article 6, of the Constitution of Nevada on the following grounds and for the following reasons, namely:
“(1) Said sections of Chapter 762 illegally delegate to an Administrative Appeals Officer judicial powers and functions in workmens compensation cases;
“(2) Said sections of Chapter 762 illegally and effectively abolish a pre-existing, long established and long recognized judicially declared, independent original cause of action for injured complainants having a judicial dispute with the Nevada Industrial Commission;
“(3) Said sections of Chapter 762 illegally gave a right to appeal decisions of an appeals officer in workmens compensation cases when such an appeal can legally lie only from a constitutional court or tribunal in such cases.”
Nev. Const. art. 3, § 1:
“The powers of the Government of the State of Nevada shall be divided into three separate departments, — the Legislative, — the Executive and the Judicial; and no persons charged with the exercise of powers properly belonging to one of these departments shall exercise any functions, appertaining to either of the others, except in the cases herein expressly directed or permitted.”
Nev. Const. art. 6, § 1:
“The Judicial power of this State shall be vested in a Supreme Court, District Courts, and in Justices of the Peace. The Legislature may also establish Courts for municipal purposes only in incorporated cities and towns.”
The realities of the law about separation of powers were stated by Mr. Justice Jackson: “. . . They [administrative bodies] have become a veritable fourth branch of the Government, which has deranged our three-branch legal theories much as the concept of a fourth dimension unsettles our three-dimensional thinking.
“Courts have differed in assigning a place to these seemingly necessary bodies in our constitutional system. Administrative agencies have been called quasi-legislative, quasi-executive or quasi-judicial, as the occasion required, in order to validate their functions within the separation-of-powers scheme of the Constitution. The mere retreat to the qualifying ‘quasi’ is implicit with confession that all recognized classifications have broken down, and ‘quasi’ is a smooth cover which we draw over our confusion as we might use a counterpane to conceal a disordered bed.” Federal Trade Comm’n v. Ruberoid Co., 343 U.S. 470, 487—488 (1952) (dissenting opinion).
There is a large number of jurisdictions holding constitutional administrative adjudication of workmen’s compensation. Most of them hold that such a determination is not exclusively judicial- in character, provided that there is the customary judicial review. See Alabam’s Freight Co. v. Hunt, 242 P. 658 (Ariz. 1926); Walters v. Blackledge, 71 So.2d 433 (Miss. 1954); Utah Fuel Co. v. Industrial Comm’n, 194 P. 122 (Utah 1920); Borgnis v. Falk Co., 133 N.W. 209 (Wis. 1911). See also Ontario Mining Co. v. Industrial Comm’n, 280 P. 483 (Colo. 1929); Grant Coal Mining Co. v. Coleman, 179 N.E. 778 (Ind. 1932). Some justify their holding by characterizing the powers of the agency as “summary,” thus implying the degree of judicial power is slight. See Grand Trunk Western Ry. v. Industrial Comm’n, 125 N.E. 748 (Ill. 1919); Cunningham v. Northwestern Improvement Co., 119 P. 554 (Mont. 1911). There have been bolder, more realistic rationales. The Supreme Court of Oregon has held that the power of the legislature to create courts such as the Industrial Commission is unlimited. See *122Evanhoff v. State Indus. Accident Comm’n, 154 P. 106 (Ore. 1915). The Supreme Court of Washington has held that, because administrative adjudication is “necessary” to the success of the scheme, it is constitutional. “Necessary” in this context may be taken to mean that each of the group of controversies delegated to administrative adjudication is an aspect of an organic whole, best handled by a single agency. See State v. Mountain Timber Co., 135 P. 645 (Wash. 1913).
See, e.g., State ex rel. Johns v. Gragson, 89 Nev. 478, 482, 515 P.2d 65, 68 (1973) (review of zoning board decision is limited to the record before the administrative tribunal, and in the absence of a showing that the agency acted fraudulently or arbitrarily, the district court may not substitute its own opinion for that of the city commissioners); Miller v. West, 88 Nev. 105, 493 P.2d 1332 (1972) (review of decision of State Welfare Division is limited to the record before the Welfare Division and must be affirmed if the decision is supported by substantial evidence). See, also, City of Reno v. Folsom, 86 Nev. 39, 464 P.2d 454 (1970); Holland Realty Inv. Co. v. State, 84 Nev. 91, 436 P.2d 422 (1968); City of North Las Vegas v. Public Serv. Comm’n, 83 Nev. 278, 429 P.2d 66 (1967).
NRS 233B.140(2):
“Within 30 days after the service of the petition, or within further time allowed by the court, the agency shall transmit to the reviewing court the original or a certified copy of the entire record of the proceeding under view. By stipulation of all parties to the review proceedings, the record may be shortened. A party unreasonably refusing to stipulate to limit the record may be taxed by the court for the additional costs. The court may require or permit subsequent corrections or additions to the record.”
NRS 233B.140(3):
“If, before the date set for hearing, application is made to the court for leave to present additional evidence, and it is shown to the satisfaction of the court that the additional evidence is material and that there were good reasons for failure to present it in the proceeding before the agency, the court may order that the additional evidence be taken before the agency upon conditions determined by the court. The agency may modify its findings and decision by reason of the additional evidence and shall file that evidence and any modifications, new findings or decisions with the reviewing court.”
NRS 233B.140(4):
“The review shall be conducted by the court without a jury and shall be confined to the record. In cases of alleged irregularities in procedure before the agency, not shown in the record, proof thereon may be taken in the court. The court, upon request, shall hear oral argument and receive written briefs.”
NRS 233B.140(5):
“The court shall not substitute its judgment for that of the agency as to the weight of the evidence on questions of fact. The court may affirm the decision of the agency or remand the case for further proceedings. The court may reverse or modify the decision if substantial rights of the appellant have been prejudiced because the administrative findings, inferences, conclusions or decisions are:
“(a) In violation of constitutional or statutory provisions;
“(b) In excess of the statutory authority of the agency;
“(c) Made upon unlawful procedure;
“(d) Affected by other error of law;
“(e) Clearly erroneous in view of the reliable, probative and substantial evidence on the whole record; or
“(f) Arbitrary or capricious or characterized by abuse of discretion or clearly unwarranted exercise of discretion.”

Where the employer, as provided by this chapter, has given notice of an election to accept the terms of this chapter, and the employee has not given notice of an election to reject the terms of this chapter, the employer shall provide and secure, and the employee shall accept, compensation in the manner provided by this chapter for all personal injuries sustained arising out of and in the course of employment.
“2. Every employer electing to be governed by the provisions of this chapter, before becoming entitled to the benefits of this chapter in the providing and securing of compensation to the employees thereunder, shall, on or before July 1, 1947, and thereafter during the period of his election to be governed by the provisions of this chapter, pay to the commission all premiums in the manner provided in this chapter. During the period of his election to be governed by the provisions of this chapter he shall comply with all conditions and provisions thereof.
“3. Failure on the part of any employer to pay all the premiums as required by the provisions of this chapter shall operate as a rejection of the terms of this chapter. In the event of any rejection of this chapter, or the terms hereof, such rejecting employer shall post a notice of rejection of the terms of this chapter upon his premises in a conspicuous place. The employer at all times shall maintain the notice or notices so provided for the information of his employees.”
Caveat: For those employers enumerated in NRS 616.275, as well as their employees, the Nevada Industrial Insurance Act is conclusive, compulsory and obligatory, and the reasoning of this concurring opinion might be inapposite as to them.
