ORDER 
 
Upon consideration of the petition for a writ of mandamus, the motion to stay, 
and the motion to expedite, it appears to the Court that: 
(1) 
The petitioner, Diamonte Taylor, seeks to invoke the original 
jurisdiction of this Court under Supreme Court Rule 43 and requests the issuance of 
a writ of mandamus directing the Superior Court to review its denial of his motion 
to suppress and to exclude all evidence collected from his smartphones at his second 
trial that was scheduled to begin on December 4, 2023.  For the reasons set forth 
below, the petition is dismissed.1 
(2) 
In 2016, a grand jury indicted Taylor for multiple crimes including first-
degree murder.  Taylor filed a motion to suppress evidence from his smartphones 
that he contended was collected under an unconstitutional search warrant.  After the 
 
1 Normally the State would be expected to respond the petition under Supreme Court Rule 
43(b)(ii), but in light of the trial schedule and the jurisdictional defects on the face of the petition, 
the Court is dismissing the petition sua sponte under Rule 29(c).  
 
2 
Superior Court denied Taylor’s motion to suppress, a jury found Taylor guilty of 
some of the charges, including first-degree murder.  On appeal to this Court, Taylor 
argued, among other things, that the Superior Court erred in denying his motion to 
suppress.  This Court agreed, holding that the search warrant was an unconstitutional 
general warrant and that the “Superior Court should have granted Taylor’s motion 
to suppress all evidence from the search of his smartphones.”2  We reversed the 
Superior Court’s judgment, vacated Taylor’s convictions, and remanded for a new 
trial consistent with our opinion.3  
(3) 
On remand to the Superior Court, the State filed an application for a 
second search warrant targeting Taylor’s smartphones.  The Superior Court granted 
the application and issued the search warrant.  Trial was scheduled to commence on 
December 4, 2023.  On March 27, 2023, Taylor filed a motion to suppress evidence 
seized from his smartphones under the second search warrant.  He argued that the  
Court’s September 2021 decision required the exclusion of this evidence in its 
entirety.  After briefing, oral argument, and supplemental submissions, the Superior 
Court advised the parties on November 9, 2023 that it would be denying the motion 
to suppress and issuing a written opinion with its rationale as soon as it was 
completed.  The Superior Court issued its written opinion on November 28, 2023.  
 
2 Taylor v. State, 260 A.3d 602, 615-19 (Del. 2021).  The Court did not address Taylor’s argument 
that the search warrant was unsupported by probable cause.  Id. at 615. 
3 Id. at 619.

That same day the Superior Court denied Taylor’s motion to stay the Superior Court 
proceedings.  According to the Superior Court docket, the jury was selected on 
November 30, 2023 and to be sworn on December 4, 2023.  
(4) 
On November 27, 2023, Taylor filed a petition for a writ of mandamus 
in this Court. Taylor did not file a motion to expedite the mandamus proceedings.  
Under Supreme Court Rule 43(b)(ii), the State’s response to the petition was not due 
for twenty days. On Saturday, December 2nd, at 4:58 p.m., Taylor finally filed a 
motion to expedite the mandamus proceedings.  He also filed a motion to stay the 
Superior Court proceedings with trial scheduled to start in less than forty-eight 
hours.        
(5) 
In Taylor’s petition for a writ of mandamus, he essentially asks this 
Court to review and reverse the Superior Court’s interlocutory decision denying his 
motion to suppress and to direct the Superior Court to exclude evidence seized from 
his smartphones under the second search warrant.  Under the Delaware Constitution, 
the Court “does not have jurisdiction to hear an interlocutory appeal in a criminal 
case.”4  The Court has regularly rejected the “use of a writ of mandamus as a means 
of reviewing an interlocutory ruling” in criminal cases.5

mandamus directing the Superior Court to quash indictments pending against the petitioner).  See 
also In re Cannon, 2018 WL 1376936, at *1 (Del. Mar. 16, 2018) (holding that the petitioner could 
not use the extraordinary writ process to overcome the Court’s lack of jurisdiction “to review an 
interlocutory order in a criminal case”); In re Shockley, 2005 WL 2475731, at *2 (Del. Aug. 16,

In addition, the petition fails to satisfy all of the criteria for issuance of 
a writ of mandamus.  A writ of mandamus will only issue if the petitioner can show: 
(i) a clear right to the performance of a duty; (ii) that no other adequate remedy is 
available; and (iii) that the trial court has arbitrarily failed or refused to perform its 
duty.6  “[I]n the absence of a clear showing of an arbitrary refusal or failure to act, 
this Court will not issue a writ of mandamus to compel a trial court to perform a 
particular judicial function, to decide a matter in a particular way, or to dictate the 
control of its docket.”7  Contrary to Taylor’s contentions, he has an adequate remedy 
in the appellate review process.8  If he is convicted after trial, he can raise the denial 
of his motion to suppress on appeal to this Court.

denial of his motion to compel as seeking impermissible review of an interlocutory order in a 
criminal case); In re Claudio, 2001 WL 117986, at *1 (Del. Jan. 30, 2001) (holding the petitioner 
could not “through mandamus, circumvent the constitutional prohibition against interlocutory 
appeals in criminal cases”); In re Middlebrook, 2000 WL 975060, at *1 (Del. May 30, 2000) 
(“Mandamus may not be used under any circumstances, however, to review interlocutory orders 
in criminal cases.”); In re Briley, 1992 WL 219070, at *3 (Del. Aug. 21, 1992) (holding that there 
was no basis for issuance of a mandamus reviewing the Superior Court’s denial of the motion to 
withdraw filed by the petitioner’s counsel because the petitioner was seeking to use the petition as 
an improper substitute for direct review of an interlocutory ruling); Cook v. State, 1985 WL 14162, 
at *1 (Del. Sept. 5, 1985) (“Moreover, a Writ of Mandamus cannot be used as a means of reviewing 
an interlocutory ruling of the Superior Court in criminal cases.”).  In Petition of State, this Court 
granted the State’s petition for a writ of mandamus during the penalty phase of a death penalty 
case based on the Superior Court’s refusal to consider the merits of the admissibility of victim 
impact evidence as required by Delaware’s capital punishment statute.  597 A.2d 1 (Del. 1991).  
The unusual circumstances of that case are not present here.

petitioner could appeal the Superior Court’s decision to this Court); In re Riley, 2008 WL 3873434,

In dismissing Taylor’s petition for a writ of mandamus, we wish to 
make it clear that we are not passing upon the merits of the Superior Court’s denial 
of the motion to suppress.  The petition raises important constitutional issues that are 
similar, but not identical to, those recently addressed by a divided court sitting en 
banc in Garnett v. State.9  This order does not address those issues, including 
whether the admission of evidence seized from Taylor’s smartphones is barred by 
this Court’s September 2021 opinion in Taylor v. State. 
NOW, THEREFORE, IT IS ORDERED, under Supreme Court Rule 29(c), 
that the petition for the issuance of a writ of mandamus is DISMISSED.  The motion 
to stay and motion to expedite are both MOOT.
