OPINION
{11 Dеfendant Kelly Lafe Garner pleaded guilty to four counts of burglary, third degree felonies, in violation of Utah Code Ann. § 76-6-202 (1999), reserving the right to appeal the district court's denial of his motion to dismiss. Because Defendant's brief is inadequate under Rule 24 of the Utah Rules of Appellate Procedure, we decline to review his claims. We accordingly affirm.
BACKGROUND
12 On June 14, 1999, Defendant was charged by information with four cоunts of burglary, third degree felonies, in violation of Utah Code Ann. § 76-6-202 (1999), three counts of theft, second degree felonies, in violation of Utah Code Ann. §§ 76-6-404 and 76-6-412(1)(a) (1999), two counts of eriminal mischief, third degree feloniеs, in violation of Utah Code Ann. § 76-6-106 (1999), and one count of theft, a class B misdemeanor, in violation of Utah Code Ann. §§ 76-6-404 and 76-6-412(1)(d) (1999). The charges were *469 based on crimes committed in Weber County between November 1997 аnd March 1998.
13 In early May 1998, a co-defendant implicated Defendant in the crimes. Thereafter, Weber County authorities continued to investigate Defendant's involvement in the crimes. They contactеd Defendant while he was in the Davis County Jail on other charges, and he agreed to talk with them upon his release. However, upon his release, Defendant fled the jurisdiction.
I 4 In June 1998, Defendant was incаrcerated in the Colorado State Prison on criminal trespass charges. Sometime in early 1999, Weber County authorities learned Defendant was incarcerated somewhere in Coloradо. On June 14, 1999, just over a year after commencing its investigation of Defendant, the Weber County prosecutor filed the infor-mations charging Defendant with the Weber County offenses. Following a hearing on Defendant's motion to dismiss, the district court found that the State did not know where Defendant was incarcerated to lodge a detainer when the informations were filed.
{5 In November 1999, Defendant was transferred to the Alabama State Prison for violating parole. At some point, the State became aware of Defendant's incarceration in Alabama. In June 2000, the State began the process of lodging a detainer under the Interstate Agreement on Detainers (IAD). See Utah Code Ann. § 77-29-5 (1999). The de-tainer was lodged on August 3, 2000.
6 On September 12, 2000, Defendant filed a 180 day demand for disposition under the IAD. See id. § 7i-29-5, art. IHl(a) The demand was received by the State on October 2, 2000. On December 22, 2000, Defendant made his initial appearance before the district court and was appointed counsel from the Weber County Public Defender's Association. At his arraignment on January 4, 2001, Defendant waived a preliminary hearing and pleaded not guilty. A trial was set for February 5, 2001. On January 25, 2001, Defendant made a motion to strike the trial date, indicating that he planned to file a motion to dismiss on speedy trial grounds. On January 29, 2001, he filed the motion to dismiss alleging that the State improperly delayed filing the informations, violating his right to due procеss, and negligently delayed filing a detainer, violating his right to a speedy trial. On April 19, 2001, Defendant pleaded guilty to four counts of burglary, reserving the right to appeal the denial of his motion to dismiss. On May 10, 2001, Defendant was sentenced to zero to five years on each count to run concurrently with each other and with his Alabama sentence. Defendant filed this appeal on May 31, 2001. On July 13, 2001, Maurice Richards and Jerald Engstrom, Weber County Public Defenders, entered their appearance as appellate counsel.
ANALYSIS
T7 In essence, Defendant claims the district court erred in denying his motion to dismiss alleging his fеderal and state due process and speedy trial rights were violated. See U.S. Const. amend. VI, XIV; Utah Const. art. I, §§ 7, 12. The State responds that we should not consider Defendant's claims because they are inadequately briefed under Rule 24 of the Utah Rules of Appellate Procedure. We agree with the State.
18 It is well established that Utah appellate courts will not consider claims that are inadequately briefed. See, e.g., State v. Lucero,
T9 Defendant's brief first fails to comply with rule 24 because instead of properly challenging the district court's findings, see Utah R.App. P. 24(a)(9), Defendant makes contrary assertions without record support. Defendant asserts the State obtained "a full and complete" twenty page statement "from the *470 co-defendant on May 5, 1998, that clearly implicated ... Defendant in the crime{[s]." Defendant then asserts the State "offered no excuse for the delay in filing the information[s], and there was no evidence the delay was caused by any action of ... Defendant." He also asserts the State "failed to file infor-mations and detainers for some twеnty months after the events occurred, where at all times the State knew where ... Defendant was housed." In so asserting, Defendant ignores the district court's findings that the co-defendant's statement was further devеloped over four to six months, authorities continued to investigate Defendant's involvement in the crimes through early 1999, Defendant fled the jurisdiction after he had agreed to talk with authorities upon his release from jail, the State was unaware of Defendant's whereabouts in Colorado when the informations were filed, and Defendant remained in the Alabama State Prison until shortly after the State became aware of Defendant's incarceration and lodged a detain-er. Furthermore, the record shows the in-formations were filed approximately fifteen, not twenty, months after the last оffense occurred, and the detainer was lodged approximately fourteen months after the infor-mations were filed.
110 "If a lower court has erred in its written findings of fact, the proper procedure is for the complaining party to challenge those findings on appeal under our clearly erroneous standard of review." Mac-Kay v. Hardy,
' 11 Defendant's brief also violates rule 24 because it fails to "set forth a coherent statement of the issues or standard of reviеw for each issue." State v. Yates,
112 Furthermore, Defendant's claims are "devoid of any 'meaningful analysis" " Marques,
*471 118 This is not the first time defense counsel, publicly funded contract attorneys, have failed to adequately brief claims of indigent defendants who have no choice as to their representаtion. 1 As we recently instructed defense counsel:
[Tjo permit meaningful appellate review, briefs must comply with the briefing requirements sufficiently to enable us to understand ... what particular errors were allegedly made, where in the record thоse errors can be found, and why, under applicable authorities, those errors are material ones necessitating reversal or other relief.
Lucero,
[ilf the questions involved in a case are of sufficient importance to justify asking this court to decide them, they are worthy of careful consideration of counsel рresenting them.... It is the duty of attorneys practicing in this court to present ... authorities supporting their views and to assist the court in reaching a correct conclusion.
Thomas,
T 14 Accordingly, we affirm.
