OPINION
SHERAN, Justice.
Consolidated appeals from the order for judgment and the judgment of the Hennepin County District Court. The matter *708 before us concerns an election contest instituted by contestant, Frank Moulton, seeking reelection, against contestee, Jack Newton, winner of the general election for alderman of the 10th ward in the city of Minneapolis. The election occurred June 8, 1965. Contestant claims the election should be nullified because: (1) The contestee failed to make timely filing of financial statements as required by Minn. St. 211.20, subds. 2 and 4, as amended by L.1963, c. 861, § 10;[1] (2) the city clerk unlawfully, in violation of Minn.St. 211.22,[2] caused contestee's name to be printed on the general election ballot; and (3) contestee, in violation of § 211.08,[3] published and circulated campaign literature containing statements concerning contestant either false or giving false impressions, which statements were known to be false or were made without adequate investigation and which tended to affect the fair and free expression of the voters. Contestant contends that such failures and publication of false statements constitute irregularities in the conduct of the election and are deliberate, serious, and material violations of the Minnesota election laws.[4]
The facts upon which the contestant seeks to support his claims are that contestee, after filing a financial statement 7 days before the primary election recording a $10 filing fee (apparently his only campaign expense), thereafter filed no statements until his attention was directed to his omissions by contestant's amended notice of contest, whereupon the missing statements were filed on June 24, 1965. In the course of the campaign, contestee received five to ten checks made out to his name, which he promptly endorsed over to his volunteer committee for the reason, as he testified, that the checks were intended for the committee but were mistakenly made payable to him. These checks were then included in financial statements duly filed by the committee. Additionally, in the course of the campaign, contestee's volunteer committee prepared and distributed *709 literature containing statements criticizing contestant for his actions while in office with respect to residential street paving, urban renewal, zoning ordinance, freeway planning, auditorium expansion, and further criticizing him for maintaining two "homes" (one outside his ward) and in dividing his time and effort between aldermanic and extra-aldermanic duties.
Upon findings that contestant failed to prove any campaign statement to be false; that such statements were "essentially true" and "constituted fair political comment on the issues of the campaign"; and that contestee's "candidacy and election were free from offensive or illegal acts," the court dismissed contestant's petition.
1. We have carefully examined the voluminous record and comprehensive briefs and are persuaded that the judgment must be affirmed.
Minn.St. 209.02, subd. 1, sets forth two grounds for an election contest: (1) "[A]n irregularity in the conduct of an election" by election officials, and (2) "deliberate, serious, and material violations" of any of the election laws by a candidate.[5] To sustain a charge that contestee failed to make a timely filing of financial statements, contestant must show that such omissions were "deliberate, serious, and material violations of the provisions of the Minnesota election law."[6] In determining the merit of contestant's claims the trial court may find, pursuant to § 211.34, that from the evidence it appears 
"* * * the offenses complained of were trivial or unimportant * * * [and] arose from accidental miscalculation or from some other reasonable cause of like nature * * * and under the circumstances it seems to the court to be unjust that the candidate shall forfeit his nomination, position or office * * *."
Such a determination is implicit in the finding made here by the lower court. We have said before that the trial court is vested with 
"* * * considerable discretion in determining whether violations of the act are trivial or unimportant and * * [u]nless it appears that there has been a clear abuse of discretion we should not reverse merely because it appears that there has been a violation which is technical rather than real."[7]
Applying this test, we cannot find that there was a "clear abuse of discretion" in the lower court's determination. Certainly the failure to timely file the financial statements was a trivial omission when we consider that contestee's volunteer committee recorded and filed all the information that should have been included in his financial statements. The five or ten checks which contestee turned over to his committee were included in its unchallenged report thus refuting any inference from contestee's failure to properly file financial statements after the primary and before the election that he was motivated by a desire to fraudulently conceal income and expenditures and thus affect the fair and free expression of the will of the voters.
Contestant relies on Dale v. Johnson, 143 Minn. 225, 173 N.W. 417. That case concerned only the scope of mandamus and not the merits of an election contest. There, the county auditor refused to issue a certificate of election to the winning candidate because no financial statements had been filed. The statute then, as now,[8]*710 made it a criminal offense for the auditor to issue a certificate under those circumstances. In a mandamus proceeding brought by the prevailing candidate to compel issuance of the certificate, we held merely that the scope of mandamus would not permit us to counter an administrative decision refusing to issue the certificate where to do so would result in our compelling an administrative officer to "violate the criminal laws of the state." 143 Minn. 226, 173 N.W. 418.
We have consistently held that the jurisdiction of the court in an election contest is solely statutory.[9] Accordingly, we hold that where an election certificate is issued administratively despite noncompliance with the requirements of filing financial statements, the court has no power to annul the election absent proof establishing a "deliberate, serious, and material" violation of the election laws by the contestee.
2. We do not agree with contestant's claim that the city clerk's wrongful entry of contestee's name on the ballot, in violation of § 211.22, constitutes an "irregularity in the conduct of the election" requiring this court to declare contestee's election void. We have said before that 
"* * * after a fair election is held and the results ascertained, mere irregularities in following statutory procedure will often be overlooked. * * *
* * * * * *
"`It is the general rule that, before an election is held, statutory provisions regulating the conduct of the election will usually be treated as mandatory and their observance may be insisted upon and enforced. After an election has been held, the statutory regulations are generally construed as directory and such rule of construction is in accord with the policy of this state, which from its beginning has been that, in the absence of fraud or bad faith or constitutional violation, an election which has resulted in a fair and free expression of the will of the legal voters upon the merits will not be invalidated because of a departure from the statutory regulations governing the conduct of the election except in those cases where the legislature has clearly and unequivocally expressed an intent that a specific statutory provision is an essential jurisdictional prerequisite and that a departure therefrom shall have the drastic consequence of invalidity.'"[10]
There is no showing here that the specific statutory provision is an "essential jurisdictional prerequisite." The trial court found "there was no fraud or bad faith, and there was no constitutional violation." In our opinion the evidence supports this finding.
3. Finally, we must refuse contestant's claims in regard to the campaign statements included in literature prepared and disseminated by contestee and his volunteer committee. No purpose will be served by reviewing each statement individually. The exhaustive memorandum of the trial court treats all of contestant's specific claims and fully satisfies us that the evidence supports the findings that the statements were made in good faith after adequate investigation; were proper campaign comments; and were essentially true. It is significant, as the trial court *711 observed, that while the campaign was in progress, the contestant did not publicly assert the falsity of the statements which he now contends should invalidate the election.
Affirmed.
