IN THE SUPREME COURT OF THE STATE OF DELAWARE

IN THE MATTER OF THE 

PETITION OF CHARLES DUFFY

FOR A WRIT OF MANDAMUS

§ No. 308, 2020

§ 

§

Submitted: September 28, 2020

Decided: October 22, 2020

Before SEITZ, Chief Justice; VALIHURA and VAUGHN, Justices.

O R D E R

After consideration of the petition for a writ of mandamus and the State’s 

answer, it appears to the Court that:

(1) In 1985, the petitioner, Charles Duffy, pleaded guilty to first-degree 

rape. He received a sentence of life imprisonment, the first twenty years of which 

were mandatory. In 2012, the Board of Parole certified Duffy for parole upon the 

successful completion of the Greentree program. On January 12, 2018, Duffy 

pleaded guilty in the Superior Court to violation of privacy. The Superior Court 

declared Duffy to be a habitual offender under 11 Del. C. § 4214(a) and sentenced 

him to six years of imprisonment. As a result of the conviction for violation of 

privacy, Duffy’s parole was also revoked.

(2) On March 16, 2020, Duffy filed a “Motion for Credit Time Served,” 

and on May 21, 2020, he filed a “Motion to Compel DOC to Apply Credit Time to 

Current Incarceration.” The Superior Court denied the motions on August 31, 2020. 
2

On September 15, 2020, Duffy filed a notice of appeal1 of the Superior Court’s 

August 31, 2020 order and a petition for a writ of mandamus. 

(3) In the petition for a writ of mandamus, Duffy seeks to invoke the 

original jurisdiction of this Court, under Supreme Court Rule 43, to issue a writ of 

mandamus requiring the Department of Correction to provide him with 204 days of 

statutory good-time credit. Relying on the transitional provisions set forth in 11 Del. 

C. § 4216, he contends that his life sentence and his 2018 sentence should run 

consecutively, not concurrently, and that he is entitled to have good-time credit

accurately calculated and applied while he is serving his 2018 sentence.

2

(4) The State filed an answer and motion to dismiss. It states that in 

preparing the response, it informed the Department of Correction (“DOC”) of 

Duffy’s petition and, as a result, DOC has credited Duffy with 204 days of statutory 

good time and 116 days of meritorious good time. The State therefore argues that 

Duffy’s petition should be dismissed as moot. It also argues that the petition should 

be dismissed because the appeal that Duffy has filed provides him with another, 

adequate remedy.

 

1 Duffy v. State, 307, 2020 (Del.) (filed Sept. 15, 2020).

2

See 11 Del. C. § 4216(a) (“Where an inmate is serving a sentence to Level V (incarceration) 

imposed not under the Truth in Sentencing Act of 1989 and receives a subsequent sentence to 

Level V under the provisions of the Truth in Sentencing Act, serving of the earlier sentence shall 

be suspended and the inmate shall serve the new Level V sentence until it is completed and then 

resume serving the original sentence.”).

(5) We conclude that the petition for a writ of mandamus should be 

dismissed. This Court’s original jurisdiction to issue a writ of mandamus is limited 

to circumstances where the respondent is a court or a judge.3 To the extent that 

Duffy asks this Court to issue a writ of mandamus to the Department of Correction, 

this Court lacks jurisdiction to do so.4

(6) To the extent that Duffy is seeking a writ of mandamus directed to the 

Superior Court, that remedy is available only 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 Superior Court has arbitrarily failed or refused to perform its duty.5 

There is no basis for the issuance of a writ of mandamus to the Superior Court in 

this case. A petitioner who has an adequate remedy in the appellate process may not 

use the extraordinary writ process as a substitute for an appeal.6 Duffy’s appeal from 

the Superior Court’s August 31, 2020 order provides him with an adequate avenue 

for raising the issues that he raised in his petition for a writ of mandamus, and the

issue of mootness may also be addressed in the appeal.

Hitchens, 600 A.2d 37, 38 (Del. 1991)).

See supra note 3. See also In re Resop, 2015 WL 5168155, at *1 (Del. Sept. 1, 2015) (recognizing 

this Court’s lack of jurisdiction to issue a writ of mandamus to DOC).

NOW, THEREFORE, IT IS ORDERED that the petition for the issuance of a 

writ of mandamus is DISMISSED.
