Linda Belle Hayes was charged with driving under the influence of alcohol, I.C. § 49-1102. Following trial, the magistrate dismissed the charge under I.C.R. 48 “in the interest of justice” because the arresting officers, by failing to administer a blood-alcohol test, acted in an arbitrary manner “which did effectively violate the Defendant’s right to equal protection under the law.” The state appealed and the district court reversed, holding that the complaint “was not properly subject to a dismissal” because the actions of the officers did not deny Hayes due process of law. Hayes then appealed. We affirm the district court’s decision.
Hayes raises several issues on appeal. The first two issues concern alleged procedural errors committed by the district court in the appeal from the magistrate’s order: (1) whether the district court could reverse the magistrate’s order without first determining that the magistrate abused his discretion; (2) whether the district court erred in prematurely deciding the appeal without waiting for oral argument. The next four issues we will discuss concern the substantive aspects of this case: (1) whether the trial court acted within the scope of authority afforded it under I.C.R. 48 in dismissing the action; (2) whether a person accused of driving under the influence has the right to a chemical test of the body’s alcohol content; (3) whether Hayes’ right to equal protection under the law was violated; and (4) whether Hayes’ due process rights were violated.
The facts are as follows. In the wee hours of September 12, 1982, Linda Hayes set out for home after spending the previous hour and a half at the Owl Club. Unfortunately for Hayes, a couple of Salmon City Police officers, on duty at one point along her route, clocked her going forty in a twenty-five mile per hour zone. They pursued her to her home where she finally came to a stop. There, in her driveway, the critical events began to happen. Engaging Hayes in conversation, the officers soon came to the conclusion that she was intoxicated. According to their testimony at trial, Hayes failed two field sobriety tests — an alphabet test and a physical dexterity test. The officers further testified that Hayes was crying, swaying, screaming and generally being uncooperative. They allegedly detected the distinct odor of alcohol about her person. Hayes denies all these characterizations. She claims to have imbibed only two drinks during her sojourn at the Owl Club and offers up a variety of reasons to explain her appearance and her actions. In any event, the net result was Hayes’ arrest for driving under the influence of alcohol. She was transported to the sheriff’s office and placed in the jail.
Shortly after her incarceration, Hayes called out to the police officers. She told the arresting officer “she would blow up a balloon if she could be released.” The balloon she referred to is an integral part of the Mobat breath test, then in use in Salmon. The procedure for administering this test is simple and painless. A person suspected of being intoxicated is instructed to *558 blow up a balloon and the breath collected therein is passed through chemicals which can be analyzed to determine alcohol content. The officers, who had not administered a Mobat test to Hayes during the original encounter in her driveway, now refused her request. They testified that their failure to give her such a test when she was originally stopped and their refusal to accept her request at the jail were based upon past experience with Hayes. Apparently she had previously been accused of the same offense two or three times. On one or two of those occasions, she was unable to generate enough lung power to inflate the balloon adequately for testing; on oné other occasion, she succeeded in blowing up a balloon, only to fail the test and suffer a conviction.
Hayes filed a motion under I.C.R. 48 for a dismissal of the charge against her. The magistrate denied the motion, citing the paucity of facts relating to the administration of Mobat tests by the Salmon police department. He suggested a number of questions which would need to be answered before he could grant such a motion and noted that Hayes would be allowed to refile the motion after trial in the event she was convicted. Following trial, the magistrate issued a decision; but, instead of reaching the merits, the magistrate granted the motion to dismiss. 1 He said:
From the above facts, it is the Court’s decision that the citation shall be dismissed under Rule 48 in the interest of justice. The officersf’] decision to not administer a mobat test was an arbitrary act which did effectively violate the Defendant’s right to equal protection under the law.
Assuming for argument that the Defendant could not have blown up the mobat balloon, the monetary loss to the State would have been less then [sic] $5.00. Furthermore, the fact of the Defendant’s failure to complete the test would have been admissable [sic] against the Defendant.
The Court feels that it would be patently unfair for a Defendant to be subject to sanctions such as loss of a driver’s license for refusal to take a mobat test, to hold that the officers may arbitrarily decide who can and cannot attempt to pass the test.
Therefore, the proper remedy in this matter is for the citation to be dismissed.
The state appealed. On May 10, the district court, acting in its appellate capacity, set a date for oral argument. At the appointed time, all were present save the district judge. On June 7 the district court filed its memorandum opinion, incongruously dated May 2, reversing the magistrate’s order. The court stated:
An annotation at 95 ALR3d 710 confirms this result in concluding: “The Courts have uniformly rejected the contention of the motorist that he was denied due process of law by the law enforcement officer’s failure to offer him a chemical sobriety test, and have held that there is no obligation to test the blood of an accused in all cases in which the motorist is arrested for driving under the influence of intoxicating liquor.”
A state may have the duty to reveal exculpatory evidence, it does not have the responsibility to discover it.
Based on this authority, the complaint against the defendant, Hayes, was not properly subject to a dismissal, and the judgment of the Magistrate is hereby reversed.
This time Hayes appealed.
I. PROCEDURAL ISSUES
Hayes contends, with some justification, that she should have been afforded the opportunity for oral argument before the district court and that, in any event, the court should not have written its decision prior to setting the date for oral argument. See I.C.R. 54(s). Cf I.R.C.P. 83(w). She also maintains that the district court erred by not explicitly finding the magistrate abused his discretion in dismissing the case *559 under I.C.R. 48. The record does not provide an explanation for the date placed on the district court’s memorandum decision. Perhaps it is only a typographical error. The failure of the district court to allow oral argument before deciding the appeal is also unexplained. The state admits that the court’s conduct was, in some ways, technically erroneous. Nevertheless, this does not entitle Hayes to relief.
When a district court acts in its appellate capacity in a civil case and reaches its decision on the basis of the record before it, “we may review the record independently of the decision of the district court.”

II. SUBSTANTIVE ISSUES
Hayes contends that a trial judge has broad discretion to dismiss a case under 1.C.R. 48. She urges us to establish just how broad this discretion is and hold that the magistrate here did not abuse his discretion in dismissing the case. We decline, however, to define the limits of a judge’s discretion under rule 48. On its face, the rule requires a judge who dismisses a case in order to “serve the ends of justice” to “state in the order of dismissal [his] reasons for such dismissal.” I.C.R. 48(b). An order stating only that the case was dismissed “to serve the ends of justice” would be insufficient. Here the magistrate did state his reason — he dismissed the case “in the interest of justice” because he believed Hayes’ right to equal protection under the law had been violated. The magistrate thus did not exceed the scope of his authority under rule 48. His reason, however, is not borne out by the record, as we discuss below. Without a valid reason supporting the decision to dismiss, the magistrate’s order cannot be upheld.
The next contention raised on appeal concerns whether a person accused of driving under the influence has a right to be given a Mobat test. The statutes relating to chemical tests of motor vehicle operators applicable at the time did not
require
that any test be given.
See
former I.C. § 49-352 (now repealed)
et seq.; see also State v. Reyna,
Hayes, however, argues that the right exists by reason of a policy of the Salmon City Police to give a Mobat test to *560 everyone accused of driving under the influence. If indeed such a policy exists, the equal protection clause would prohibit the discriminatory application of this policy. The policy was unwritten. The Chief of the Salmon City Police testified that he never told his officers they must give the test to everyone — the decision was left in the hands of the officer at the scene. At the most, there was a “practice” of giving a Mobat test to everyone accused of driving under the influence. The test was, in fact, administered in the vast majority of cases. The question is whether a right to be given a Mobat test was created under these circumstances. If there is no right, there can be no infringement of a right and thus no violation of the equal protection clause. See Tussman and tenBroek, The Equal Protection Of The Laws, 37 Cal.L.Rev. 341, 364 (1949). Even if we will assume that some “right” to be given a Mo-bat test is vested in everyone accused of driving under the influence by the Salmon City Police, nevertheless, we hold there was no infringement of that right sufficient to constitute a violation of the equal protection clause.
Hayes contends that her right to equal protection under the laws was violated when the police discriminatorily first failed and then refused to give her a Mobat test. The guaranty of equal protection under the laws has been defined “to mean that no person or class of persons shall be denied the same protection of the laws which is enjoyed by other persons or other classes in like circumstances in their lives, liberty and property and in the pursuit of happiness.”
People v. Romo,
“[T]o establish an instance of discriminatory application of the laws such that equal protection standards have been violated, there must first be shown a deliberate plan of discrimination based on some unjustifiable” or arbitrary classification.
Henson v. Dept. of Law Enforcement,
The magistrate found the following facts to have been established by the record. Hayes failed an alphabet test and physical dexterity test administered by the arresting officers at the time and place of the arrest. She was not offered a Mobat test at that time because on one or two previous occasions she had been unable to blow up the balloon, which is an indispensable requirement of the test. Hayes had managed to blow up a balloon on one previous occasion. Finally, sometime after she. was transported to jail, Hayes indicated she would take a Mobat test if she could be released from jail. The magistrate held that the failure or refusal to administer a Mobat test under these circumstances was “arbitrary.”
“An arbitrary act is one done without any apparent reason therefor.”
Verdugo Hills Hospital, Inc. v. State Dept. of Health,
Finally, Hayes contends she was denied due process by the failure of the police to “preserve” allegedly exculpatory evidence. Hayes alleges that a Mobat test would have shown she was
not
intoxicated and that the failure to “preserve” this evidence — i.e., to give her a Mobat test— amounted to an unconstitutional suppression of evidence by the state. We disagree. “The duty of the prosecution to disclose evidence necessarily includes the duty to use earnest efforts to preserve evidence for possible use by a defendant.”
State v. Wells,
The decision of the district court, reversing the magistrate’s order which dismissed the charge of driving under the influence against Linda Belle Hayes, is affirmed. The cause is remanded to the magistrate’s division for proceedings consistent with the opinion.
Notes
. It is unclear whether the motion to dismiss under I.C.R. 48 was renewed at the close of trial, but both parties treat it as if it were. So shall we.
. The present statutes relating to operation of vehicles while intoxicated and to the giving of tests for alcohol content are compiled in chapter 80, title 18, Idaho Code.
