On November 26, 2001, the Pierce County Prosecuting Attorney, Gerald Horne, distributed a memorandum (Horne memorandum) to all Pierce County Superior Court judges, the Department of Assigned Counsel, and the Department of Corrections announcing that, as a general policy, the prosecuting attorney’s office would no *576longer recommend drug offender sentencing alternative (DOSA) sentences according to ROW 9.94A.660. During the subsequent appeal of Charles Watson’s sentence, the Court of Appeals held sua sponte that the Horne memorandum was an ex parte communication, although harmless as to that particular offender. State v. Watson, 120 Wn. App. 521, 525, 86 P.3d 158 (2004). The Court of Appeals “holding” was substantively incorrect.
I. FACTUAL AND PROCEDURAL HISTORY
¶2 On August 16, 2002, a jury convicted Watson of unlawful delivery of a controlled substance within 1,000 feet of a school bus route stop.1 Prior to sentencing, the State filed a sentencing brief and provided defense counsel with copies. The prosecuting attorney attached to the brief a copy of the Horne memorandum, which announced the State’s policy not to recommend DOSA sentences due to fundamental problems with the program.
¶3 At the sentencing hearing on September 13, 2002, Watson sought a DOSA sentence, and the State recommended against DOSA and in favor of a sentence at the low end of the standard range. The court imposed a low-end standard range sentence. Watson appealed his sentence.
¶4 On appeal, the Court of Appeals affirmed the sentence in a published opinion. See Watson, 120 Wn. App. at 536. In doing so, however, the court “held” sua sponte that the Horne memorandum, circulated before Watson even committed his crime, was an improper ex parte communication. Id. at 525, 535. The court then went on to reason that because the prosecuting attorney made defense counsel aware of the communication and gave him an opportunity to respond before sentencing, the improper ex parte communication was harmless to Watson. Id. at 535.
¶5 Although satisfied with the result reached by the Court of Appeals, the State sought discretionary review of *577the court’s determination of an improper ex parte communication. We granted the State’s petition for review. State v. Watson, 152 Wn.2d 1036, 103 P.3d 801 (2004).
II. ISSUE
¶6 Was the Horne memorandum an improper ex parte communication with the trial court in this case?
III. ANALYSIS
f7 We may grant review and consider a Court of Appeals opinion if it “involves an issue of substantial public interest that should be determined by the Supreme Court.” RAP 13.4(b)(4). This case presents a prime example of an issue of substantial public interest. The Court of Appeals holding, while afFecting parties to this proceeding, also has the potential to affect every sentencing proceeding in Pierce County after November 26, 2001, where a DOSA sentence was or is at issue. Although the Court of Appeals reasoning would require remand only if the policy letter were kept “secret,” it invites unnecessary litigation on that point and creates confusion generally.2 See id. Further, the court’s treatment of communications as ex parte in later proceedings has the potential to chill policy actions taken by both attorneys and judges — they may fear that their statements or actions in various public roles would later be treated as ex parte communications.
¶8 RAP 3.1 need not bar our review. RAP 3.1 states: “Only an aggrieved party may seek review by the appellate court.” Although the State may not technically be an aggrieved party because it received a favorable disposition by the Court of Appeals, contrary to the dissent’s assessment, we can and should still review the Court of Appeals opinion. The RAPs are intended to “be liberally interpreted to promote justice and facilitate the decision of *578cases on the merits.” RAP 1.2(a). Moreover, we may choose to disregard the RAPs if the interests of justice require. RAP 1.2(c). Review is appropriate in this rare situation where an incorrect holding will have sweeping implications but does not actually render a party “aggrieved” within RAP 3.1.
¶9 Similarly, even traditional standing to bring a lawsuit is not an absolute bar to a court’s review where an important issue is at stake. Grant County Fire Prot. Dist. No. 5 v. City of Moses Lake, 150 Wn.2d 791, 803, 83 P.3d 419 (2004) (holding that when an issue “is of substantial public importance, immediately affects significant segments of the population, and has a direct bearing on commerce, finance, labor, industry, or agriculture,” we will “take a ‘less rigid and more liberal’ approach to standing.” (quoting Wash. Natural Gas Co. v. Pub. Util. Dist. No. 1 of Snohomish County, 77 Wn.2d 94, 96, 459 P.2d 633 (1969))). Likewise, courts may hear cases that have been rendered completely moot if an issue is of substantial public interest. Cathcart-Maltby-Clearview Cmty. Council v. Snohomish County, 96 Wn.2d 201, 208, 634 P.2d 853 (1981) (“A moot case will be reviewed if its issue is a matter of continuing and substantial interest, it presents a question of a public nature which is likely to recur, and it is desirable to provide an authoritative determination for the future guidance of public officials.”); see also State v. Ross, 152 Wn.2d 220, 228, 95 P.3d 1225 (2004).
¶10 Given the sweeping implications of the Court of Appeals decision, we review the definition of “ex parte communication” and application thereof, both questions of law, de novo. See City of Tacoma v. William Rogers Co., 148 Wn.2d 169, 181, 60 P.3d 79 (2002); State v. Johnson, 128 Wn.2d 431, 443, 909 P.2d 293 (1996).
¶11 Neither RPC 3.5 nor CJC 3(A)(4),3 governing ethical restrictions for attorneys and judges regarding ex parte *579communications, defines the term “ex parte communication.” Washington case law also does not clearly define the term.
¶12 “[I]n the absence of a provided definition, this court will give a term its plain and ordinary meaning ascertained from a standard dictionary.” State v. Taylor, 150 Wn.2d 599, 602, 80 P.3d 605 (2003). Black’s Law Dictionary defines “ex parte communication” as “[a] communication between counsel and the court when opposing counsel is not present.” Black’s Law Dictionary 296 (8th ed. 2004). That definition assumes that there is a proceeding involving the court, with counsel and opposing counsel, and that the communication regards the proceeding at hand. Black’s further defines “ex parte” as something being made by one party: “Done or made at the instance and for the benefit of one party only, and without notice to, or argument by, any person adversely interested; of or relating to court action taken by one party without notice to the other.” Id. at 616; see also State v. Moen, 129 Wn.2d 535, 541 n.3, 919 P.2d 69 (1996) (“By definition, an ex parte order is done on the application of one party . . . .”). Black’s multiple definitions of “party” also assume that a cause of action exists in which the party is a participant. See Black’s, supra, at 1154.
¶13 Moreover, courts generally apply the term ex parte communication to communications made by or to a judge,4 during a proceeding, regarding that proceeding,5 without notice to a party. See, e.g., State v. Bourgeois, 133 Wn.2d 389, 407-08, 945 P.2d 1120 (1997) (finding an improper ex parte communication between the bailiff (the alter ego of *580the judge) and the jury where a juror told the bailiff of juror intimidation which the bailiff relayed to the judge, but which the judge did not pass on to counsel); Sherman v. State, 128 Wn.2d 164, 181, 205, 905 P.2d 355 (1995) (finding an ex parte communication where a judge’s judicial extern contacted the Washington monitored treatment program to find out about the monitoring of physicians in the program, specifically the plaintiff in a case before the judge involving an employment dispute over the plaintiff’s drug use); Buckley v. Snapper Power Equip. Co., 61 Wn. App. 932, 937-38, 813 P.2d 125 (1991) (holding that a direct communication between a trial judge and a guardian ad litem regarding settlement, which was passed on to defense counsel without the knowledge or participation of the plaintiff’s counsel, was an improper ex parte communication); State v. Romano, 34 Wn. App. 567, 568-69, 662 P.2d 406 (1983) (concluding there was an ex parte communication where a judge, during a current proceeding, contacted third parties to verify the defendant’s income without the defendant’s knowledge); United States v. Forbes, 150 F. Supp. 2d 672, 677 (D.N.J. 2001) (reasoning the “term [ex parte] contemplates that one actually be a party to a matter before the communication of another party is considered ‘ex parte.’ ”).
¶14 The Court of Appeals cited no opinion concluding there was an ex parte communication where there was not an existing proceeding nor any case finding a general communication not directed at any specific proceeding to be ex parte to some specific proceeding. Instead, the two cases the court cited discussed communications made during proceedings, by parties to the proceedings, regarding those proceedings. See Watson, 120 Wn. App. at 534-35 (citing In re Pers. Restraint of Boone, 103 Wn.2d 224, 234-35, 691 P.2d 964 (1984) (holding petitioner was denied due process in his probation revocation proceeding when his probation officer submitted a secret report to the trial court); Romano, 34 Wn. App. at 568-69 (reversing and remanding where the trial judge’s ex parte communication regarding the defen*581dant’s income created the appearance of impropriety)). Neither those cases nor our other ex parte communication case law supports finding that the prosecuting attorney’s general DOSA policy was an ex parte communication in Watson’s proceeding.
IV. CONCLUSION
¶15 We hold that the Court of Appeals holding that the Horne memorandum was an ex parte communication is incorrect.
C. Johnson, Bridge, Chambers, Owens, and J.M. Johnson, JJ., concur.
The crime took place on or about April 4, 2002.
The Court of Appeals reasoning in this case has already been discussed and distinguished in another ex parte communication case. See State v. Juarez, noted at 122 Wn. App. 1012, 2004 Wash. App. LEXIS 1303.
Watson asserts that CJC 3(A)(4) supports defining ex parte communications to include communications made when there is no judicial proceeding in place. Resp’t’s Suppl. Br. at 7-8. The rule states: “Judges should accord to every person who is legally interested in a proceeding, or that person’s lawyer, full right to be heard according to law, and, except as authorized by law, neither initiate nor *579consider ex parte or other communications concerning a pending or impending proceeding.” CJC 3(A)(4). But “impending” does not refer to hypothetical future cases that are not yet imminent — Webster’s Third New International Dictionary defines “impending” as what “is about to occur” or is “imminent.” Webster’s Third New International Dictionary 1132 (2002). Indeed, the comment to the rule describes the “proscription against communications concerning a proceeding,” not a future or potential proceeding. CJC 3(A)(4) cmt.
Statements made by or to the judge can involve a party or a neutral third party. See CJC 3(A)(4) cmt.
The comment to CJC 3(A)(4) describes the “proscription against communications concerning a proceeding.”
