T1 Plaintiff Anne Pierce argues that the trial judge should have certified his disqualification because Defendant's counsel and counsel's father each gave $5,000 to the judge's campaign, and counsel solicited other campaign contributions on the judge's behalf while the case was pending before the judge. We hold that the record is sufficient to show that the judge should have disqualified. Defendant's counsel failed to show that his campaign efforts on behalf of the judge were minimal in comparison to the total amount raised and number of people soliciting funds on the judge's behalf.
T2 The trial judge assigned to adjudicate the Pierce divorcee was a candidate for District Judge while the divorcee proceeding was pending. Plaintiff sought to disqualify the trial judge on the basis that counsel for Defendant and counsel's father each contributed $5,000.00 to the judge's campaign while *794the divorce was pending. She further stated that Defendant Gene O. Pierce had communicated to her that she would not win in the custody dispute involving their child. The trial judge denied the in camera request to disqualify.
I 3 Plaintiff re-presented her motion to the Chief Judge. At the hearing on that motion Defendant's counsel admitted his donation to the campaign and stated that "[pleople that I have solicited have donated money, including my father...." No further facts were presented on the degree or nature of counsel's solicitation of funds on behalf of the trial judge. The Chief Judge declined to require disqualification.
14 On appeal the Court of Civil Appeals determined that a trial judge's error in not certifying his or her disqualification should be reviewed first in the trial court pursuant to District Court Rule 15, and then by the Supreme Court on an application for mandamus. It stated that when a party does not seek extraordinary relief the alleged error of a judge declining to disqualify is not reviewed on a subsequent appeal unless public policy demands the disqualification. We vacate the opinion of the Court of Civil Appeals, hold that the plaintiff preserved the disqualification error for review on appeal, and that the trial judge should have disqualified.
I. Disqualification Procedure
15 The first question presented is whether a party must bring an application for mandamus in this Court to challenge a judge's decision that denies a party's application to disqualify the judge. District Court Rule 15 specifies the procedure for disqualifying trial court judges.
Rule 15. Disqualification of Judges in Civil and Criminal Cases.
a. Before filing any motion to disqualify a judge, an in camera request shall first be made to the judge to disqualify or to transfer the cause to another judge. If such request is not satisfactorily resolved, not less than ten (10) days before the case is set for trial a motion to disqualify a judge or to transfer a cause to another judge may be filed and a copy delivered to the judge.
b. Any interested party who deems himself aggrieved by the refusal of a judge to grant a motion to disqualify or transfer a cause to another judge may re-present his motion to the Chief Judge of the county in which the cause is pending or, if the disqualification of a Chief Judge is sought, to the Presiding Judge of the administrative district by filing in the case within five (5) days from the date of said refusal a written request for re-hearing. A copy of the request shall be mailed or delivered to the Chief Judge or Presiding Judge, to the adverse party and to the judge who entered the original order. If the hearing before the second judge results in an order adverse to the movant, he shall be granted not more than five (5) days to institute a proceeding in the Supreme Court or the Court of Criminal Appeals for a writ of mandamus. - Neither the Supreme Court nor the Court of Criminal Appeals will entertain an original proceeding to disqualify a judge or to direct a judge to transfer a cause to another judge unless it is shown that the relief sought was previously denied by the judge to whom the matter was re-presented in accordance with this rule. An order favorable to the moving party may not be reviewed by appeal or other method.
c. An original proceeding in mandamus to disqualify a judge in a civil action or proceeding shall be brought in the Supreme Court; an original proceeding in mandamus to disqualify a judge in a criminal case or proceeding shall be brought in the Court of Criminal Appeals. If mandamus is not brought in the appellate court designated as proper by this rule, the case will be transferred to the proper court either on motion or sua sponte. Art. VII, §§ 4 Okla. Const.
12 O.S.1991 Ch. 2, App. 1, Rule 15.
Rule 15(c) covers "an original proceeding in mandamus to disqualify a judge in a civil action." This language identifies the court in which to seek extraordinary relief in civil and criminal actions, but does not re*795quire that mandamus be sought in one of the supervisory courts.
T6 The rule-mandated procedure works with the statutory procedure for disqualifica-. tion.
§ 1408. Disqualification of judge, claim of-Mandamus
Any party to any cause pending in a court of record may in term time or in vacation file a written application with the clerk of the court, setting forth the grounds or facts upon which the claim is made that the judge is disqualified, and request said judge so to certify, after reasonable notice to the other side, same to be presented to such judge, and upon his failure so to do within three (8) days before said cause is set for trial, application may be made to the proper tribunal for mandamus requiring him so to do.
20 O.S.1991 § 1403.
A review of the history of § 1408 shows its mandatory and discretionary elements.
17 The original purposes of § 1403 were to provide a procedure for parties to avoid a trial before a disqualified judge, and to cereate a court record on the disqualification issue so that the jurisdiction of the replacement judge would appear on the face of the record. Ex parte Hudson, 1910 OK CR 3, 3 Okia.Crim. 393, 107 P. 735, 737, and 3 Okla.Crim. 393, 106 P. 540, 544. That court also noted that the statute was created to correct the practice of disqualifying a judge upon a mere affidavit after a case had been called for trial, because abuse of that procedure had "thrown into confusion" the business of the court. Ingles v. McMillan, 1911 OK CR 5, 5 Okla.Crim. 130, 113 P. 998, 1000, Lewis v. Russell, 1910 OK CR 4, 4 Okla.Crim. 129, 111 P. 818, 819.
18 We have explained that since the adoption of § 1403 1 where a party had knowledge of the alleged grounds of the disqualification of the trial judge for more than three days prior to the trial, and that party did not use the procedure prescribed by that section, the party cannot urge the disqualification on appeal, or in a collateral attack, on the judgment rendered and orders made by said judge. State ex rel. Dabney v. Ledbetter, 1932 OK 229, 156 Okla. 23, 9 P.2d 728, 729, quoting, Holloway v. Hall, 1920 OK 287, 79 Okla. 163, 192 P. 219, 2202 Thus, when the statute states that a party "may" file a written application with the court clerk to disqualify a judge the language is permissive in the sense that a party may or may not file the application, but if a party seeks judge disqualification we have held that filing the statutory application is mandatory.3
T9 Our opinions indicate that when the procedure in § 1408 is followed a party may raise the disqualification issue on a subsequent appeal. Does the term "may" in the language "application may be made to the proper tribunal for mandamus" allow a party the option of raising the disqualification issue on appeal instead of by mandamus, or is "may" used in the same way as in the language stating that a party "may" file a written application for disqualification with the court clerk? The published opinions of this Court indicate the former, ie., that a mandamus proceeding is not required.
We have stated:
The procedure, under proper cireum-stances, may be by mandamus, or the party may object and save his exceptions to the overruling of his petition for disqualification and proceed with his cause, and thus save the question for review. In any *796event, the complaining party must proceed by application to the court as provided by statute, supra. If this is not done the litigant is deemed to have waived the question (State ex rel. Attorney General v. Davenport, [1927 OK 137] 125 Ok. 1, 256 P. 340), unless the cireumstances are such that the demands of public policy would require disqualification. In such case the parties may not waive the disability.
In re Miller's Estate, 1938 OK 289, 182 Okla. 534, 78 P.2d 819, 822, citation added.
Miller's Estate indicates that after a party preserves the disqualification issue in the trial court the alleged error may be raised by a mandamus proceeding or in a subsequent appeal. See also Jones v. Cabaniss, 1939 OK 122, 185 Okla. 237, 90 P.2d 650, 651, where we stated that a party "was authorized to proceed by mandamus or to present his defense and preserve his rights throughout the trial." Accord, Morissette v. Musgrave, 1940 OK 486, 188 Okla, 222, 108 P.2d 123, 125, quoting, Jones v. Cabaniss, supra. This concept was subsequently cited in Graham v. Graham, 1967 OK 210, 434 P.2d 245, where the party did not bring a mandamus proceeding, and we concluded that the party failed to show that the trial court abused its discretion in refusing to disqualify.
110 We conclude that a party seeking disqualification of a judge in a civil proceeding must make an in camera request of the judge to disqualify or to transfer the cause to another judge as required by Rule 15, and then upon the judge's refusal the party must file a written application in the cause, as required by § 1403, and upon refusal of the motion,4 re-present the motion to the Chief Judge or the Presiding Judge as required by Rule 15. We also conclude that if the judge is not then disqualified as requested, the party seeking disqualification may seek extraordinary relief in the form of mandamus as authorized by Rule 15 and § 1408, or as an alternative to a mandamus proceeding, preserve the disqualification issue for review on appeal from the subsequent judgment. In re Miller's Estate, supra. Accord, Harmon v. Harmon, 1997 OK 91, n. 3, 943 P.2d 599, 603, (original proceeding to disqualify judge converted to an appeal).
111 In our case today an application was filed in the trial court and the issue was represented as required by Rule 15. We need not address those factual cireumstances where failure to follow the rule is legally excused or when the nature of the disqualification involves public policy that may be raised on appeal although not previously raised in the trial court.5
II. Campaign Contribution and Solicitation of Campaign Contributions
$12 Some courts have determined that lawyers' contributions to judicial campaigns are normal incidents to the campaigns, and the contributions do not indicate any eloser relation between the contributors and the recipients than would ordinarily exist between members of the same local bar. Mac-Kenzie v. Super Kids Bargain Store, Inc., 565 So.2d 1332, 1338 (Fla.1990), quoting, Frade v. Costa, 342 Mass. 5, 171 N.E.2d 863, 865 (1961). However, the MacKenzie court noted that a lawyer's contribution in conjunction with an additional factor, such as the lawyer serving as co-chair of the trial judge's judicial election campaign which was ongoing at the time of the underlying lawsuit, may require a judge to disqualify. MacKenzie v. Super Kids Bargain Store, Inc., 565 So.2d at n. 5, 1338. See also Aetna Casualty and Surety Co. v. Berry, 669 So.2d 56, 79 (Miss.1996), where the court required disqualification when a lawyer had formerly represented the judge and was acting as a spokesman for the judge's campaign during the decisional period of the litigation. Another court has distinguished ongoing per*797sonal relationships and those in the past, and declined to require disqualification when the lawyer was the judge's campaign manager six years prior to the complaint. Gluth Bros. Constr. Co. v. Union Nat. Bank, 192 Ill.App.3d 649, 139 Ill.Dec. 650, 548 N.E.2d 1364, 1368 (1989).
113 A judge "should disqualify himself or herself in a proceeding in which the judge's impartiality might reasonably be questioned. ..." 5 O.S.Supp.2000, Ch. 1, App. 4, Code of Judicial Conduct, Canon 3(E)(1).6 We have said that when cireumstances and conditions surrounding litigation are of such a nature that they might reasonably cast doubt and question as to the impartiality of any judgment the trial judge may pronounce, said judge should certify his or her disqualification. Johnson v. Board of Governors of Registered Dentists of State of Oklahoma, 1996 OK 41, ¶ 32, 913 P.2d 1339, 1348, quoting, Sadberry v. Wilson, 1968 OK 61, ¶ 12, 441 P.2d 381, 384. We have also said that in disqualification proceedings the courts must be sensitive to the appearances of possible impropriety as well as to actual occurrences. Holloway v. Hopper, 1993 OK 56, 852 P.2d 711, 713. The question of a judge's appearance of impartiality is determined by an objective standard. Johnson v. Board of Governors of Registered Dentists of State of Oklahoma, 1996 OK 41, 913 P.2d at 1348.
114 May a trial judge's impartiality be reasonably questioned when that judge receives campaign contributions and campaign assistance from a lawyer during litigation where that lawyer is appearing before that judge? We have required a judge to disqualify when one of the parties to an action had previously distributed the judge's campaign literature, actively campaigned for the judge and other candidates on behalf of the judge, and had previously attended political conventions with the judge. State ex rel. Larecy v. Sullivan, 1952 OK 290, 207 Okla. 128, 248 P.2d 239, 243. The Oklahoma Judicial Ethics Advisory Panel has issued an advisory opinion stating that a lawyer's campaign assistance of a minimal nature and a campaign contribution of $50 for a judge's campaign do not require that judge to disqualify when the lawyer subsequently appears before the judge. 2001 OK JUD ETH 5.7 We also note that a judge or judicial candidate should not personally solicit campaign funds, but instead relies upon committees of responsible persons acting on behalf of the judge or candidate. 5 O.S.Supp.1998, Ch. 1, App. 4, Code of Judicial Conduct, Canon 5(C(2).8 We *798make reference to this Canon not for the purpose of showing that any violation occurred, but to illustrate the importance our Code of Judicial Conduct gives to the solicitation of judicial campaign funds. We further note that during the time at issue campaign contributions to judge were statutorily limited to $5,000. 21 O.S.Supp. 1997 § 187.1. Similarly, the rules of the Ethics Commission limited certain campaign contributions to $5,000 per family. 74 O.S.Supp.1997 & 1998, Ch. 62, App., Rule 257:10-1-2.
{15 In our case today, counsel and counsel's father each contributed $5,000 to the trial judge's campaign during the litigation and prior to trial. We are not provided with any evidence in the record to show whether this $10,000 represented a significant portion of the judge's total campaign contributions. We are not told whether these two contributions were the only contributions in this maximum amount, or whether the timing of the contributions is of special significance. We are told that counsel solicited other contributions for the judge's campaign, but we are not told the amount of these contributions or the manner in which the solicitations were made.
116 We agree with the Oklahoma Judicial Ethics Advisory Panel that the mere fact of a lawyer's contribution to a judge's campaign does not per se require that judge's disqualification when the lawyer comes before him. But we are of the opinion that a judge's "impartiality might reasonably be questioned" when, as in this case, (1) a lawyer makes a campaign contribution to that judge in the maximum amount allowed by statute, and (2) a member of that lawyer's immediate family makes a comparable maximum contribution, and (8) that lawyer further assists the judge's campaign by soliciting funds on behalf of the judge, and the contributions and solicitations occur during a pending case in which the lawyer is appearing before that judge. If the party resisting the motion to disqualify chooses to defend the motion by showing that the contributions and solicitations were a minimal part of the judicial campaign then facts to that effect should be made part of the record. A party opposing a claim or cause of action may provide evidence for the purpose of denying one of the elements to that claim or cause of action. Long v. Ponca City Hospital, Inc., 1979 OK 32, 593 P.2d 1081, 1087. Such evidence is not before us, and we conclude that upon the facts of this case the plaintiff sufficiently showed that the trial judge should have disqualified.
III. Due Process and an Appellate Remedy
T17 Not all questions of judicial qualification involve constitutional validity. Aetna Life Ins. Co. v. Lavoie, 475 U.S. 813, 820, 106 S.Ct. 1580, 89 L.Ed.2d 823 (1986). But there is no doubt that due process is violated if a judge has a "direct, personal, substantial pecuniary interest" in the proceedings or when a judge has responsibilities over a party independent of any judicial duties and the judge then acts as a decision-maker in litigation involving that party. Bushert v. Hughes, 1996 OK 21, n. 21, 912 P.2d 334, 338, citing, Tumey v. Ohio, 273 U.S. 510, 47 S.Ct. 437, 71 L.Ed. 749 (1927) and Ward v. Village of Monroeville, 409 U.S. 57, 93 S.Ct. 80, 34 L.Ed.2d 267 (1972); Alpha Epsilon Phi Tau Chapter Housing Association v. City of Berkeley, 114 F.3d 840, 844 (9th Cir.1997). The record does not show any direct, personal, substantial pecuniary interest of the judge in the proceedings. Neither does the record show any actual bias by the judge.
{18 Due process jurisprudence includes the concept of the appearance of a fair trial. The High Court has explained that the reach of due process jurisprudence requires not only a fair tribunal, but also the appearance of a fair tribunal. In re Murchison, 349 U.S. 133, 136, 75 S.Ct. 623, 99 L.Ed. 942 (1955). Due process "preserves both the appearance and reality of fairness, 'generating the feeling, so important to a popular government, that justice has been done,' ... by ensuring that no person will be deprived of his interests in the absence of a proceeding in which he may present his case with assurance that *799the arbiter is not predisposed to find against him." Marshall v. Jerrico, Inc., 446 U.S. 238, 242, 100 S.Ct. 1610, 64 L.Ed.2d 182 (1980), quoting, Joint Anti-Fascist Committee v. McGrath, 341 U.S. 123, 172, 71 S.Ct. 624, 649, 95 L.Ed. 817 (1951) (Frankfurter, J., concurring). That Court has stated that " "Justice must satisfy the appearance of justice,' and this 'stringent rule may sometimes bar trial by judges who have no actual bias and who would do their very best to weigh the seales of justice equally between contending parties,'...." Marshall, 446 U.S.at 243, 100 S.Ct. 1610, quoting, Offutt v. United States, 348 U.S. 11, 14, 75 S.Ct. 11, 99 L.Ed. 11 (1954), and In re Murchison, 349 U.S. at 136, 75 S.Ct. 623. See also, Mayberry v. Pennsylvania, 400 U.S. 455, 465, 91 S.Ct. 499, 27 L.Ed.2d 532 (1971).
YT19 The common law contains a presumption that a judge is not biased, and a party must point to some fact to overcome the presumption to require disqualification because of bias. Aetna Life Ins. Co. v. Lavote, 475 U.S. at 820, 106 S.Ct. 1580, quoting, 3 W. Blackstone, Commentaries *361. Accord, Carter v. State, 1994 OK CR 49, 879 P.2d 1234, 1242, (There is a presumption of impartiality on the part of judges as to matters before them, and to make a claim of judicial bias a party must demonstrate some prejudice which denied him or her due process or fundamental fairness). Similarly, a party must point to some fact to substantiate a claim that the appearance of a fair trial is not present, or that the judge's impartiality might reasonably be questioned. We conclude that due process must include the right to a trial without the appearance of judge partiality arising from counsel's campaign contributions and solicitation of campaign contributions on behalf of a judge during a case pending before that judge.9
120 What is the appropriate appellate remedy for the error of a trial judge in refusing to disqualify in a divorcee proceeding where the appearance is that the judge's impartiality might reasonably be questioned? Characterizing the error to disqualify as a violation of due process shows that the decree must be reversed. We have indicated in a divorce case that we would affirm a decree if it was just and equitable even if a trial judge showed bias. White v. White, 1955 OK 56, 281 P.2d 745, 748. On the other hand, we have said that a party is entitled to reversal of a proper judgment when the judge was statutorily required to disqualify. Hill v. Hill, 1950 OK 183, 203 Okla. 260, 220 P.2d 450, 451. White treats a judge-disqualification as a type of error subject to a form of harmless-error analysis, while Hill treats the error similar to a fundamental error where prejudice need not be shown.10 Hill is the proper example for our case today. Violations of some constitutional rights, because of their importance to a fair trial, are not treated, as a matter of law, as harmless error. Satterwhite v. Texas, 486 U.S. 249, 256, 108 S.Ct. 1792, 1797, 100 L.Ed.2d 284 (1988); Chapman v. California, 386 U.S. 18, 23, 87 S.Ct. 824, 827, 17 L.Ed.2d 705 (1967).11 Some rights are "too fundamental and absolute to allow courts to indulge in nice caleula-tions as to the amount of prejudice resulting from [their] denial." Glasser v. U.S., 315 U.S. 60, 75, 62 S.Ct. 457, 86 L.Ed. 680 (1942) (referring to the right of effective assistance *800of counsel, and citing in its support Tumey v. Ohio, 273 U.S. 510, 535, 47 S.Ct. 437, 445, 71 L.Ed. 749.) We have noted that the appearance of justice is often as important as the proper administration of justice. Lewis v. Arbuckle Wilderness, Inc., 1988 OK 104, 763 P.2d 90, 91. Campaign contributions and solicitation of contributions of funds for judges by lawyers appearing before those judges in such amounts as to give off an appearance of partiality is not the type of error to which this Court will apply a harmless error standard.
%$21 When an order of a judge in a civil proceeding denies a disqualification application that order will not be reversed on appeal unless a clear abuse of discretion is shown. Graham v. Graham, 1967 OK 210, 434 P.2d 245, 246; Merritt v. Hunter, 1978 OK 18, 575 P.2d 623, 624. Generally, a clear abuse of discretion occurs when the decision challenged is against, or not justified by, reason and evidence. Patel v. OMH Medical Center, Inc., 1999 OK. 33, ¶ 20, 987 P.2d 1185, 1194; Abel v. Tisdale, 1980 OK 161, ¶ 20, 619 P.2d 608, 612. We conclude that the orders declining to disqualify the trial judge are contrary to our precedent and the evidence in the record.
22 Plaintiff raises the disqualification issue on appeal and on certiorari. Her appellate brief challenges the child custody determination, the court's order suspending husband's support obligation for a period of time, and the trial court's order that each party pay his or her own attorney's fees. Her brief does not specifically challenge the granting of the divorce. Both parties petitioned for divoree in the trial court, and the court granted a divorce to each party.
123 Generally, the judgment of a court rendered by a disqualified judge is not void, but voidable error, and the right to disqualify the judge is a personal privilege that may be waived. Collins v. Mid-Continent Pipeline Co., 1999 OK 56, ¶ 7, 6 P.3d 1050, 1052; State v. Davenport, 1927 OK 137, 256 P. 340, 345; Holloway v. Hall, 1920 OK 287, 79 Okla. 163, 192 P. 219, 220. We need not discuss today those cireumstances where public policy requires disqualification when the party has waived the issue. This is so because of the policy expressed in 43 O.S. 1991 § 127;
§ 127. Time when judgments in divorce actions become final -Effect of appeal
Every decree of divorce shall recite the day and date when the judgment was rendered. If an appeal be taken from a judgment granting or denying a divorce, that part of the judgment does not become final and take effect until the appeal is determined. If an appeal be taken from any part of a judgment in a divorcee action except the granting of the divorce, the divorce shall be final and take effect from the date the decree of divorce is rendered, provided neither party thereto may marry another person until six (6) months after the date the decree of divorce is rendered; that part of the judgment appealed shall not become final and take effect until the appeal be determined.
This statute separates that part of the decree that grants the divorce from other parts for the purpose of the effect of an appeal. Wilks v. Wilks, 1981 OK 91, 632 P.2d 759, 761. In Harmon v. Harmon, 1997 OK 91, 943 P.2d 599, we also treated marital status different from other claims in matrimonial litigation. Therein a party raised a disqualification issue on appeal and we determined it was moot because the trial judge was no longer a judge of the District Court. Id., 1997 OK 91, 943 P.2d 599, at n. 5. Both parties in Harmon requested divorce, and in reversing the judgment in part we said that: "We, therefore, can see no harmful error in upholding the trial court's granting of a divorcee based on the counterclaim as it concerns the parties' status and the dissolution of the marriage." Harmon v. Harmon, at ¶ 17, 943 P.2d at 605. In other words, where both parties sought dissolution of the marital status and neither appealed that issue, we left intact the status created by the divorcee decree although the disqualification issue was not resolved on the merits. Similarly, we reverse the judgment of the trial court, except as to the parties' status as being divorced. That part of the divorce decree granting both parties a diyorce is left undisturbed by our opinion herein.
*801IV. Appellate Attorney's Fees
124 Plaintiff requests appellate attorney's fees,. The right to appellate attorney's fees for matrimonial litigation is determined by this Court as part of the appeal. Chamberlin v. Chamberlin, 1986 OK 30, 720 P.2d 721, 727-728. Therein we commented on 12 O.S. § 1276, (now codified at 43 O.S. 1991 § 110) and said that
A § 1276 counsel fee award does not depend upon the claimant's status as a pre vailing party. Where sufficient funds and property are available to pay counsel fees, each party should bear its own litigation expense.
Id., 1986 OK 30, at n. 31, 720 P.2d at 727.
The record shows that Plaintiffs monthly income was $1789.00 while Defendant's was $3333.00, and Plaintiff points to this fact in her brief. Plaintiffs brief requests that the appellate court engage in "balancing of the equities" in awarding an appellate attorney's fee.
125 We decline to award appellate attorney's fees to either party. Cham-berlin requires us to examine the availability of funds and property of each party. Id. This requires the parties, in their application for attorney's fees, to point to those facts showing that equity requires one party to pay the other party's attorney's fees. The fact of income, by itself, is thus usually insufficient to show that equity requires one party to bear the cost of appellate attorney's fees. Neither party to the appeal has made the required showing, and both Plaintiffs and Defendant's requests for appellate attorney's fees are denied.
126 The opinion of the Court of Civil Appeals is vacated. The divorcee decree of the District Court is affirmed in part and reversed in part, and the matter remanded to that court for further proceedings consistent with this opinion.

Sealy, 1919 OK 304, 77 Okla. 244, 187 P. 235, 242, (statutory procedure is an adequate trial court remedy and a disqualification complaint upon appeal will not be heard if the judge was not requested to disqualify).
. The term "may" is usually construed to imply permissive or discretionary conduct, as opposed to creating a mandatory requirement. G.S. v. Ewing, 1990 OK 1, 786 P.2d 65, 72.
. The judge's refusal must be made a part of the trial court record. Clark v. Board of Education of Independent School District No. 89 of Oklahoma County, 2001 OK 56, ¶ 7, 32 P.3d 851 (mandate issued October 12, 2001).
. See, e.g., State ex rel. Dabney v. Ledbetter, 1932 OK 229, 156 Okla. 23, 9 P.2d 728, 730, (Court stated that where the disqualification of a judge is considered a matter of public policy, a waiver will not be allowed, and the judge is not authorized to sit in a case even with the consent of the parties).
. 5 O.S.Supp.2000, Ch. 1, App. 4, Code of Judicial Conduct, Canon 3(E):
E. Disqualification.
(1) A judge should disqualify himself or herself in a proceeding in which the judge's impartiality might reasonably be questioned, including but not limited to instances where:
(a) the judge has a personal bias or prejudice concerning a party or a party's lawyer, or personal knowledge of disputed evidentiary facts concerning the proceeding;
(b) the judge served as a lawyer in the matter in controversy, or a lawyer with whom the judge previously practiced law served during such association as a lawyer concerning the matter, or the judge has been a material witness concerning it;
(c) The judge knows that he or she, individually or as a fiduciary, or the judge's spouse, parent or child wherever residing, or any other member of the judge's family residing in the judge's household, has an economic interest in the subject matter in controversy or has an interest more than de minimis that could be substantially affected by the'proceeding;
(d) The judge or the judge's spouse, or a person within the third degree of relationship to either of them, or the spouse of such a person;
(1) is a party to the proceeding, or an officer, director or trustee of a party;
(ii) is acting as a lawyer in the proceeding;
(iii) is known by the judge to have an interest more than de minimis that could be substantially affected by the proceeding;
(iv) is to the judge's knowledge likely to be a material witness in the proceeding.
(2) A judge shall keep informed about the judge's personal and fiduciary economic interests, and make a reasonable effort to keep informed about the personal economic interests of the judge's spouse and minor children residing in the judge's household.
. That same Ethic's Panel advisory opinion, issued after the ruling in question here, goes on to say "As to a large donation (such as $5,000.00) we suggest the judge should recuse without a request from counsel for at least a year after the campaign."
. Canon 5 was amended effective October 5, 1998. The trial judge ruled upon the motion to disqualify on May 22, 1998. Canon 7(B)(2) in effect at that time stated, in part, that: "A candidate, including an incumbent judge, for a judicial office that is filled by public election between *798competing candidates, should not himself solicit campaign funds, but he may establish committees of responsible persons to secure and manage the expenditure of funds for his campaign."
. We do not hold that due process is violated in every case where counsel makes a campaign contribution and solicits funds on behalf of a judge during a pending matter. However, where such appearance of partiality is shown the party opposing that claim may provide evidence for the purpose of denying that appearance of partiality. Long v. Ponca City Hospital, Inc., supra.
. See, e.g., Walker v. American Ins. Co., 1927 OK. 471, 128 Okla. 132, 261 P. 918 (when reviewing a claim of an erroneous jury instruction a judgment is not disturbed if the error is harmless); Waggoner v. Town & Country Mobile Homes, Inc., 1990 OK 139, 808 P.2d 649, 657, (error in an instruction will be deemed harmless unless it is a substantial violation of a fundamental constitutional or statutory right or resulted in a miscarriage of justice).
. Of course, whether a particular fundamental right is violated may, in some circumstances, be defined by using a standard that examines the prejudice, impact, or affect upon those claiming such status. See, e.g., Glover v. U.S., 531 U.S. 198, 202-203, 121 S.Ct. 696, 148 L.Ed.2d 604 (2001), (Court discussed the prejudice prong of a Sixth Amendment ineffective assistance of counsel claim); City of Edmond v. Wakefield, 1975 OK. 96, 537 P.2d 1211, 1213, (substantive due process standard includes an analysis of the reasonableness of the "impact" upon those affected).
