OPINION
¶ 1 Arizona Rule of Civil Procedure 38.1(e) requires the superior court to “promptly notify counsel in writing of the placing of casеs on the Inactive Calendar.” We hold that a notice issued several months prior to placing the case on the Inаctive Calendar does not comply with this rule.

¶ 2 In April 2008, American Asphalt and Grading Company (“American Asphalt”) sued CMX, L.L.C., for profеssional negligence and breach of implied warranty. On October 1, 2008, the Maricopa County Superior Court issued an order (“150-Day Order”) informing American Asphalt that if it did not file a Motion to Set and Certificate of Readiness as required by Rule 38.1(a), the ease would be placed on the Inactive Calendar after January 20, 2009, and dismissed without further notice on or after March 23, 2009.
¶ 3 American Asphalt did not file a Motion to Set and the ease was dismissed without further notice on April 29, 2009. American
¶ 4 We granted review to clarify the requirements of Rule 38.1(e). We have jurisdictiоn under Article 6, Section 5(3) of the Arizona Constitution and A.R.S. § 12-120.24 (2003).

¶5 Arizona Rule of Civil Procedure 38.1(d) requires that “every case in which a Motiоn to Set and Certificate of Readiness has not been served within nine months after the commencement thereof’ shall be placed on the “Inactive Calendar.” Under that rule, cases remaining on the Inactive Calendar for two months without either the filing of a Motion to Set or a court order allowing continuance on that Calendar “shall be dismissed without prejudice for lack of prosecution.” Rule 38.1(e) states:
The clerk of the court or court administrator, whoever is designatеd by the presiding judge, shall promptly notify counsel in writing of the placing of cases on the Inactive Calendar, and no further nоtice shall be required prior to dismissal.
¶ 6 American Asphalt argues that the 150-Day Order did not satisfy Rule 38.1(e) because the order did nоt issue when the case was placed on the Inactive Calendar. We use rules of statutory construction to interpret court rules.
See Preston v. Kindred Hosps. W., L.L.C.,
¶ 7 Read in isolation, the phrase “of the рlacing of cases on the Inactive Calendar,” rather than “when a ease is placed on the Inactive Calendar,” could be read to mean that Rule 38.1(e) is satisfied if attorneys are notified at any time that cases will be placed on the Inactive Calendar on some specified future date. Under that interpretation, Mar-icopa County’s 150-Day Order would comply with the rale.
¶ 8 Based on the rale’s directive that the court shall “promptly” notify counsel of the placement of eases on the Inactive Calendar, however, we conclude that Rule 38.1(e) requires contemporaneous (or nearly contemporaneous) notice when a ease is placed on the Inactive Calendаr. As noted above, Rule 38.1(d) directs the court to “place on the Inactive Calendar every case in which a Motiоn to Set and Certificate of Readiness” are not served within nine months. Rule 38.1(e), by requiring the court to “promptly notify counsel in writing оf the placing of cases on the inactive calendar,” is most plausibly read to refer to notice when the aсtion identified in Rule 38.1(d) occurs—that is, when the case is actually placed on the Inactive Calendar. Any other interprеtation would imply that the court’s placing a case on the Inactive Calendar under Rule 38(d)(1) means something different than thе “placing of cases on the Inactive Calendar” in Rule 38.1(e).
¶ 9 Construed most reasonably and in context, Rule 38.1(e) requires notification when a case is placed on the Inactive Calendar. Because the 150-Day Order did not notify American Asрhalt when the ease was placed on the Inactive Calendar, but rather gave notice only of the court’s intentiоn to do so in the future, the order did not comply with Rule 38.1(e).
¶ 10 In so holding, we do not disapprove of Maricopa County’s 150-Day Ordеr, which provides useful advance notice to counsel. But local practices must comport with and cannot supplant the rules of civil procedure.

¶ 12 Here, unlike Copeland, American Asphalt did receive notice, albeit not the nоtice required under Rule 38.1(e), of the consequences of failing to file a Motion to Set. Express notice was set forth in the 150-Day Order (printed on a pink sheet of paper) as well as in Rule 38.1(d). Nonetheless, in an excess of caution, we vaсate the court of appeals’ decision and remand the case to the superior court because thе record does not make clear whether that court considered the 150-Day Order dispositive. On remand, the superior court should follow the analysis in Copeland and determine what effect, if any, the absence of Rule 38.1(e)—compliant notice had on the conduct of counsel.
