Circuit Court for Anne Arundel County

Case No. 02-K-95-000205

Argued: December 5, 2014
We decide: (I) whether a probation agent’s instruction to comply with a condition 

of mandatory supervision creates a condition of probation that is outside the ambit of the

standard condition of probation to obey the probation agent’s lawful instructions; and (II) 

whether such an instruction is inconsistent with the separation of powers doctrine. 

We hold that: (I) a probation agent’s instruction to comply with a condition of 

mandatory supervision does not create a condition of probation that is outside the ambit of 

the standard condition of probation to obey the probation agent’s lawful instructions; and 

(II) such an instruction is not inconsistent with the separation of powers doctrine. 

BACKGROUND 

 The State, Petitioner/Cross-Respondent, charged Charles William Callahan 

(“Callahan”), Respondent/Cross-Petitioner, with first-degree rape and other crimes that 

arose out of the abduction of a three-year-old child. On August 7, 1995, Callahan pled 

guilty to kidnapping and third-degree sexual offense. On September 11, 1995, the Circuit 

Court for Anne Arundel County (“the circuit court”) sentenced Callahan to twenty-five 

years’ imprisonment, with all but twenty years suspended, for kidnapping, and ten years’ 

imprisonment concurrent for third-degree sexual offense, followed by five years of 

probation. On that date, Callahan signed an order of probation, in which he agreed to, 

among other conditions: “1. Report to [his] Probation Agent as directed and follow his/her 

lawful instructions[.]”1

 

1On October 9, 1996, the circuit court modified the sentence for kidnapping to 

twenty-five years’ imprisonment, with all but seventeen years suspended, followed by five 

years of probation. 
- 2 - 

On or about March 4, 2009, Callahan was released from imprisonment early under 

mandatory supervision.2 On March 4, 2009, Callahan signed a “Mandatory Supervision 

Release Certificate,” in which he agreed to, among other “special conditions”: “Comply as 

directed by [his] parole/probation agent with the Division of Parole and Probation’s sexual 

offender management program, which may include . . . polygraph testing[.]” 

On or about July 1, 2011, Agent Marsha Briley-Mays (“Agent Briley-Mays”) of the 

State’s Division of Parole and Probation in its Department of Public Safety and 

Correctional Services became both Callahan’s probation agent and his mandatory 

supervision agent. On August 2, 2011, Agent Briley-Mays gave Callahan a letter that 

stated: “[Y]ou are scheduled for a polygraph examination on August 8, 2011 at 10 a[.]m. . 

. . . Please adjust your schedule to ensure your presence . . . . Failure to report may result 

in a Violation of Probation[.]” (Emphasis omitted). Callahan failed to report for the 

polygraph examination.3

Agent Briley-Mays requested a warrant and prepared a “Statement of Charges” in 

which she stated that Callahan violated the condition of probation: “1. Report to your 

Probation Agent as directed and follow his/her lawful instructions.” On October 24, 2011, 

the circuit court conducted a hearing at which Agent Briley-Mays testified. The circuit

“‘Mandatory supervision’ [is] a conditional release from confinement that is 

granted to an inmate under” certain circumstances. Md. Code Ann., Corr. Servs. (1999, 

2008 Repl. Vol.) (“CS”) § 7-101(g)(1). “An individual on mandatory supervision is subject 

to[] all laws, rules, regulations, and conditions that apply to parolees[.]” CS § 7-502(b)(1). 

For this case’s purposes, mandatory supervision is identical to parole. 

3Callahan previously had been ordered to take polygraph examinations and had 

complied. 
- 3 - 

court determined that Callahan violated the order of probation by violating the condition 

of probation: “1. Report to your Probation Agent as directed and follow his/her lawful 

instructions.” On December 5, 2011, the circuit court ordered that Callahan serve the

balance of his sentence. 

Callahan applied for leave to appeal, and the Court of Special Appeals granted the 

application and reversed, holding that the circuit court erred in determining that Callahan 

violated the order of probation. See Callahan v. State, 215 Md. App. 146, 160, 79 A.3d 

967, 976 (2013). Specifically, the Court of Special Appeals concluded that Agent BrileyMays’s instruction to report for a polygraph examination created “a new, more onerous 

condition [of probation] that was not fairly within the ambit of those laid down by the 

[sentencing] court . . . . To hold otherwise . . . would clearly be contrary to the separation 

of powers doctrine[.]” Id. at 159-60, 79 A.3d at 975-76 (citation and internal quotation 

marks omitted). 

The State petitioned for a writ of certiorari, raising one issue: Whether the Court of 

Special Appeals was correct in concluding “that the circuit court violated the doctrine of 

the separation of powers” in determining that Callahan violated the order of probation. 

Callahan conditionally cross-petitioned for a writ of certiorari, raising one issue: Whether 

the Court of Special Appeals was correct in concluding that the circuit court erred in 

determining that Callahan violated the order of probation because Agent Briley-Mays’s 

instruction created “a new, more onerous condition [of probation] that was not fairly within 

the ambit of those laid down by the [sentencing] court[.]” This Court granted the petition 

and the conditional cross-petition. See State v. Callahan, 437 Md. 422, 86 A.3d 1274

DISCUSSION 

I.

Callahan contends that the circuit court erred in determining that he violated the 

order of probation because Agent Briley-Mays’s instruction to comply with a condition of 

mandatory supervision created a new, more onerous condition of probation that was outside 

the ambit of the condition of probation to obey Agent Briley-Mays’s lawful instructions.5

Specifically, Callahan argues that Agent Briley-Mays lacked the authority to instruct 

Callahan to comply with a condition of mandatory supervision, as the condition of 

probation to obey Agent Briley-Mays’s lawful instructions related only to implementing 

the other conditions of probation. The State responds that Agent Briley-Mays’s instruction 

did not create a new, more onerous condition of probation that was outside the ambit of the 

condition of probation to obey Agent Briley-Mays’s lawful instructions because Callahan 

agreed, and was legally required, to comply with conditions of mandatory supervision and 

obey Agent Briley-Mays’s lawful instructions. 

 

4At oral argument, Callahan’s counsel advised that Callahan has again been released 

from imprisonment early “because of the accumulation of diminution credits.” At oral 

argument, the parties asserted that this circumstance does not render this case moot. We 

agree. See Adkins v. State, 324 Md. 641, 656, 598 A.2d 194, 202 (1991) (“Because the 

finding . . . that [a probationer] violated [an order of] probation will have the same, or 

similar, collateral legal consequences as the underlying criminal conviction, the appeal of 

the probation violation finding, like the appeal of the underlying criminal conviction, is not 

rendered moot simply because [the probationer] has served the sentence imposed.”). 

5We first address the non-constitutional issue that Callahan raised in the conditional 

cross-petition, as a “court[] should not decide constitutional issues unnecessarily.” Lupfer 

v. State, 420 Md. 111, 130 n.10, 21 A.3d 1080, 1091 n.10 (2011) (brackets, citation, and 

internal quotation marks omitted). 
- 5 - 

Generally, an appellate court reviews for clear error a trial court’s determination that 

a probationer violated an order of probation. See Hammonds v. State, 436 Md. 22, 32, 80 

A.3d 698, 704 (2013). That said, where (as here) the facts are undisputed—and thus, 

whether the probationer violated the order of probation is a purely legal issue—the 

appellate court reviews without deference the trial court’s determination that the 

probationer violated the order of probation. See generally Fuster v. State, 437 Md. 653, 

671, 89 A.3d 1114, 1124 (2014) (“We review de novo the trial court’s relation of facts to 

the applicable law.” (Brackets, citation, ellipsis, and internal quotation marks omitted)). 

In Hudgins v. State, 292 Md. 342, 348, 438 A.2d 928, 931 (1982), this Court stated: 

[F]requently, the nature of the probationary penalty is such that the 

circumstances of a case . . . render it desirable, or perhaps necessary, that the 

condition of probation be expressed in somewhat general terms. Such a 

general expression is permissible, so long as it is contemplated that the court 

or its designee (usually the probation authority) will provide the probationer 

with reasonable, specific direction within the ambit of the initially expressed 

general condition, and such guidance is in fact given. 

(Footnote omitted); see also Edwards v. State, 67 Md. App. 276, 281, 507 A.2d 212, 215 

(1986) (A probation authority cannot “impose new, more onerous conditions of its own 

that are not fairly within the ambit of those laid down by the [sentencing] court.”); Watson 

v. State, 17 Md. App. 263, 274, 301 A.2d 26, 31-32, cert. denied, 268 Md. 754 (1973)

(“[C]onditions [of probation] must be clear, definite and capable of being properly 

comprehended and understood not only by the [probationer,] but [also] by” the probation 

authority. (Citation omitted)). 

 For example, the Court of Special Appeals has held that trial courts erred in 

determining that probationers violated orders of probation: where an order of probation 
- 6 - 

required a probationer to pay fines and costs by a particular deadline, and a probation 

authority instructed the probationer to pay in full before the deadline, see Edwards, 67 Md. 

App. at 281-82, 507 A.2d at 215-16; where an order of probation required a probationer to 

obey his probation agent’s lawful instructions, and his probation agent instructed him to 

enter drug treatment, see Costa v. State, 58 Md. App. 474, 484, 483, 473 A.2d 942, 947 

(1984); and where an order of probation required a probationer to “conform to all rules of 

conduct imposed by [her] probation agent[,]” and her probation agent instructed her to 

enter drug treatment, see Phelps v. State, 17 Md. App. 341, 344, 343, 303 A.2d 430, 432, 

431 (1973). 

 By contrast, in Hudgins, 292 Md. at 349, 347, 438 A.2d at 930-31, this Court 

rejected a probationer’s argument that a condition of probation “to ‘cooperate with the 

Maryland State Police in tracking down criminals’ was too vague to be enforceable[.]” 

Instead of concluding that the condition of probation was per se unenforceable, this Court 

remanded to the trial court with directions to find “what reasonable, specific instructions, 

if any, were given [to] the probationer by the police and his cooperation or failure to do 

so[.]” Id. at 349, 438 A.2d at 931.6

Upon review of the applicable authorities and careful consideration of the issue, we 

conclude that a probation agent’s instruction to comply with a condition of mandatory 

supervision does not create a new, more onerous condition of probation that is outside the 

 

6The trial court heard only “general, conclusory [testimony] as to lack of cooperative 

activity with the police on the [probationer’s] part[.]” Hudgins, 292 Md. at 349, 438 A.2d 

at 931.
- 7 - 

ambit of a condition of probation to obey the probation agent’s lawful instructions. Such 

an instruction is clearly lawful, as the probation agent simply instructs the probationer to 

do what the probationer has already agreed, and is legally required, to do. In other words, 

a probation agent’s instruction to comply with a condition of mandatory supervision does 

not require a probationer to do anything more than what the probationer is already obligated 

to do. Because complying with a condition of mandatory supervision benefits the 

probationer by maintaining his or her early release from imprisonment on conditions with 

which the probationer has agreed to comply, a probation agent’s instruction to comply with 

a condition of mandatory supervision is far from onerous. 

A condition of probation requiring a probationer to obey a probation agent’s lawful 

instructions is “clear, definite and capable of being properly comprehended and understood 

not only by the [probationer,] but [also] by” the probation agent. Watson, 17 Md. App. at

274, 301 A.2d at 31-32. In imposing a suspended sentence and probation, a sentencing 

court obviously contemplates that, if/when the probationer is released from imprisonment 

early under mandatory supervision, the probationer will comply with the conditions of 

mandatory supervision while in the community. Probation and mandatory supervision 

share many characteristics. As is the case here, probation and mandatory supervision often 

both arise from the commission of the same crime; are both generally conditioned on the 

probationer’s proper behavior in the community; and often share several identical 
- 8 - 

conditions,

7

 thus allowing one act or omission to be both a violation of a condition of 

probation and a violation of a condition of mandatory supervision. Thus, it is not a stretch 

of reasoning at all to conclude that a sentencing court contemplates that a probationer 

would obey a probation agent’s lawful instruction to comply with a condition of mandatory 

supervision.

Callahan takes the position that a probationer may disobey a probation agent’s 

instruction to comply with a condition of mandatory supervision because the condition of 

probation to obey a probation agent’s lawful instructions allegedly relates only to 

implementing the other conditions of probation. This Court’s precedent, however, 

contradicts Callahan’s contention—which is essentially that a probation agent’s instruction 

is outside the ambit of a condition of probation unless the condition of probation spells out 

in exact terms the probation agent’s ability to give the instruction or the instruction is 

related to a specific condition of probation. This Court has never required such an extreme 

level of specificity in an order of probation; to the contrary, this Court has recognized that, 

“frequently, the nature of the probationary penalty is such that the circumstances of a case 

. . . render it desirable, or perhaps necessary, that the condition of probation be expressed 

in somewhat general terms.” Hudgins, 292 Md. at 348, 438 A.2d at 931. Accordingly, in 

Hudgins, id. at 349, 347, 438 A.2d at 931, 930, this Court rejected a probationer’s argument 

 

7For example, probation and mandatory supervision often share the following 

identical conditions: working; obeying all laws; refraining from possessing controlled 

dangerous substances; appearing in court when notified; reporting as directed to an agent; 

obeying the agent’s lawful instructions; allowing the agent to visit one’s residence; 

notifying the agent of an arrest; getting the agent’s permission before leaving the State; and 

getting the agent’s permission before changing one’s residence or employment.
- 9 - 

that a condition of probation “to ‘cooperate with the Maryland State Police in tracking 

down criminals’ was [per se] too vague to be enforceable[.]” In doing so, this Court 

determined that an order of probation need not spell out in exact terms a probation agent’s 

ability to give an instruction; instead, an order of probation may allow a probation agent a 

degree of latitude in enforcing a general condition of probation. See id. at 348, 438 A.2d 

at 931 (“[A] general [condition of probation] is permissible, so long as it is contemplated 

that the court or its designee (usually the probation authority) will provide the probationer

with reasonable, specific direction within the ambit of the initially expressed general 

condition, and such guidance is in fact given.” (Footnote omitted)).

We are unpersuaded by Callahan’s reliance on Edwards, 67 Md. App. 276, 507 A.2d 

212, Costa, 58 Md. App. 474, 473 A.2d 942, and Phelps, 17 Md. App. 341, 303 A.2d 430, 

for the contention that a probation agent’s instruction to comply with a condition of 

mandatory supervision creates a new, more onerous condition of probation that is outside 

the ambit of a condition of probation to obey the probation agent’s lawful instructions. In 

Edwards, Costa, and Phelps, probation agents unilaterally invented conditions of probation 

with which the probationers had not agreed, and with which they had not been legally 

required to comply in exchange for their early releases from imprisonment; in none of these 

three cases had a probationer been released from imprisonment early on parole or under 

mandatory supervision. By contrast, where a probationer is released from imprisonment 

early under mandatory supervision, the probationer agrees, and is legally required to 

comply, with conditions of mandatory supervision in exchange for his or her early release 

from imprisonment. Under such a circumstance, a probation agent does not unilaterally 
- 10 - 

invent a condition of probation by instructing the probationer to comply with a condition 

of mandatory supervision, as the probationer has already agreed, and is legally required, to 

do so. Thus, contrary to Callahan’s contention, mandatory supervision does not give the 

probation agent “a blank check . . . to impose new conditions of probation” or empower 

the probation agent to instruct the probationer to do whatever the probation agent deems 

appropriate.8

To the extent that Callahan relies on dicta from Phelps and Costa for the contention 

that a condition of probation to obey a probation agent’s lawful instructions relates only to 

implementing the other conditions of probation, such reliance is unpersuasive. In Phelps, 

17 Md. App. at 344, 303 A.2d at 431, the Court of Special Appeals stated: “While we need 

not undertake to define [the] scope [of a condition of probation to “conform to all rules of 

conduct imposed by the probation agent”], it appears to apply to day to day supervision 

of a probationer’s conduct in his home environment, including required or prohibited 

activities.” (Emphasis added). As that Court’s qualifying language makes clear, this 

statement is dicta, and was unnecessary to that Court’s holding that “[a] requirement for 

custodial care or treatment of an institutional nature should be imposed only by the 

[sentencing] court, and not, as a rule of conduct, by the probation agent.” Id. at 344, 303 

 

8At oral argument, Callahan’s counsel hypothesized that, if we did not adopt 

Callahan’s position, a probationer would violate an order of probation by disobeying a 

probation agent’s instruction to comply with any law—for example, a city ordinance that 

limits the height of fences. It appears that, under such a circumstance, the probationer 

would have violated the order of probation by failing to obey all laws in the first place. In 

any event, our holding is limited to a probation agent’s instruction to comply with a 

condition of mandatory supervision.
- 11 - 

A.2d at 431-32. In support of its dicta, the Court of Special Appeals provided no authority, 

engaged in no analysis, and offered no explanation for its perception of what the scope of 

the condition of probation “appear[ed]” to be. Id. at 344, 303 A.2d at 431. Later, in Costa, 

58 Md. App. at 483, 478, 473 A.2d at 947, 944, the Court of Special Appeals repeated the 

same dicta, including its qualifying language, from Phelps, even though the condition of 

probation in Costa was to follow a probation agent’s lawful instructions, not to conform to 

all rules of conduct imposed by a probation agent. Without explanation, the Court of 

Special Appeals treated the condition of probation in Costa as identical to the condition of 

probation in Phelps. See Costa, 58 Md. App. at 483, 473 A.2d at 947 (“That same argument 

was raised by the State and rejected by us . . . in Phelps[.]”). 

Regardless of whether equating the two different conditions of probation was 

permissible under Costa’s particular circumstances, such an approach would be completely 

unworkable here. At issue is a condition of probation to obey a probation agent’s lawful 

instructions, not a condition of probation to conform to any and all rules of conduct 

imposed by a probation agent. This distinction is critical; as noted above, a probation 

agent’s instruction to comply with a condition of mandatory supervision is lawful, as the 

probation agent simply instructs the probationer to do what the probationer has already 

agreed, and is legally required, to do. We decline to adopt the dicta from Phelps and Costa. 

We reject Callahan’s contention that, when a sentencing court grants probation, the 

probationer lacks notice that the probationer will violate the order of probation by 

disobeying a probation agent’s instruction to comply with a condition of mandatory 

supervision. A typical condition of probation is not phrased: “Obey your probation agent’s 
- 12 - 

lawful instructions as long as the order of probation spells out in exact terms the probation 

agent’s ability to give the instruction or what the instruction might be.” The typical 

condition of probation is phrased along the lines of: “Obey your probation agent’s lawful 

instructions.” This condition of probation provides the probationer with notice that the 

probationer will violate the order of probation by disobeying the probation agent’s 

instruction if the instruction is lawful. It is not subject to reasonable dispute that a probation 

agent’s instruction to comply with a condition of mandatory supervision is lawful, as the 

probation agent simply instructs the probationer to do what the probationer has already 

agreed, and is legally required, to do. As such, a probationer may expect that disobeying 

a probation agent’s instruction to comply with a condition of mandatory supervision will 

result in the imposition of the probationer’s sentence’s balance. 

We note that our holding is equally applicable regardless of whether one person is 

both the probation agent and mandatory supervision agent of a probationer; in other words, 

our holding does not turn on the circumstance that Agent Briley-Mays was both Callahan’s 

probation agent and his mandatory supervision agent. At oral argument, the parties agreed 

that it is at least common—perhaps even standard practice—for one person to be both the 

probation agent and mandatory supervision agent of a probationer. If that were not the 

case, then the Division of Parole and Probation9 would need to assign each probationer to 

one probation agent and a different mandatory supervision agent. Such a result would not

supervision until the expiration of the individual’s maximum term or terms of 

confinement[.]” CS § 6-104(a)(1)(ii). 
- 13 - 

only greatly increase public expenditures, but also hinder the probationer; for example, the 

probationer could be instructed by the probation agent to be at one place at a particular 

time and instructed by the mandatory supervision agent to be at another place at the same 

time. 

Similarly, our holding does not turn on which condition of mandatory supervision 

with which Agent Briley-Mays instructed Callahan to comply; it is inconsequential that the 

condition of mandatory supervision was to report for a polygraph examination (as opposed 

to a different condition of mandatory supervision). The critical circumstance is that, where 

a probationer is released from imprisonment early under mandatory supervision, the 

probationer agrees, and is legally required, to comply with all conditions of mandatory 

supervision in exchange for his or her early release from imprisonment. As such, a 

probation agent’s instruction to comply with a condition of mandatory supervision is not 

onerous, and a probationer is on notice that the probationer will violate the order of 

probation by disobeying a probation agent’s instruction to comply with a condition of 

mandatory supervision.10

For the above reasons, a probation agent’s instruction to comply with a condition of 

mandatory supervision does not create a new, more onerous condition of probation that is 

outside the ambit of a condition of probation to obey the probation agent’s lawful 

 

10Likewise, our holding does not turn on the circumstance that the condition of 

mandatory supervision with which Agent Briley-Mays instructed Callahan to comply was 

a “special condition,” as opposed to a general one. Callahan does not dispute that the 

“special condition” label that was used in the “Mandatory Supervision Release Certificate” 

is immaterial.

instructions.

II.

The State contends that the circuit court clearly determined that Callahan violated a 

condition of probation, not a condition of mandatory release, and that the circuit court’s 

determination did not violate the separation of powers doctrine. Callahan responds that the 

circuit court erred in determining that he violated the order of probation because Agent 

Briley-Mays’s instruction to comply with a condition of mandatory supervision was 

inconsistent with the separation of powers doctrine. Specifically, Callahan argues that, 

through Agent Briley-Mays’s instruction, the executive branch usurped the judiciary’s 

powers. 

An appellate court reviews without deference whether a trial court’s decision was 

constitutional. See generally Corbin v. State, 428 Md. 488, 498, 52 A.3d 946, 951 (2012) 

(“[W]e review the ultimate question of constitutionality de novo[.]” (Citation omitted)). 

“[T]he Legislative, Executive and Judicial powers of Government ought to be 

forever separate and distinct from each other; and no person exercising the functions of 

one of said Departments shall assume or discharge the duties of any other.” Md. Decl. of 

Rts. Art. VIII; see also Getty v. Carroll Cnty. Bd. of Elections, 399 Md. 710, 730, 926 A.2d 

216, 229 (2007) (Article 8 of the Maryland Declaration of Rights “explicitly prohibit[s] 

one branch of government from assuming or usurping the power of any other branch.”). 

 We conclude that a probation agent’s instruction to comply with a condition of 

mandatory supervision is not inconsistent with the separation of powers doctrine. A court 

chooses conditions of probation and determines whether a probationer has violated an order 
- 15 - 

of probation. See Md. Code Ann., Crim. Proc. (2001, 2008 Repl. Vol., 2014 Supp.) (“CP”) 

§ 6-221 (“On entering a judgment of conviction, the court may suspend the imposition or 

execution of sentence and place the defendant on probation on the conditions that the court 

considers proper.”); CP § 6-223(a) (“A circuit court or the District Court may end the 

period of probation at any time.”); see also Simms v. State, 65 Md. App. 685, 688-89, 501 

A.2d 1338, 1340 (1986) (“Placing a convicted person on probation is peculiarly a judicial 

act. It is part of the sentencing function.”). Thus, a court may choose a condition of 

probation that a probationer obey a probation agent’s lawful instructions, and the court may 

determine that the probationer has violated the order of probation by disobeying the

probation agent’s instruction to comply with a condition of mandatory supervision. 

 We reject Callahan’s contention that, under such a circumstance, the Maryland 

Parole Commission11 (part of the executive branch) usurps the judiciary’s powers by 

essentially choosing conditions of probation.12 The sentencing court—not any part of the 

executive branch—imposes the condition of probation that the probationer obey the 

probation agent’s lawful instructions. And, as explained above in Part I, in granting 

probation, the sentencing court obviously contemplates that, if the probationer is released 

from imprisonment early under mandatory supervision, the probationer will comply with 

the conditions of mandatory supervision; thus, the sentencing court contemplates that the 

 

11The Maryland Parole Commission may “negotiate, enter into, and sign 

predetermined parole release agreements[.]” CS § 7-205(a)(2). 

12Callahan goes on to assert that the executive branch cannot choose a condition of 

probation, just as the judiciary cannot choose a condition of mandatory supervision. Cf. 

Simms, 65 Md. App. at 691, 501 A.2d at 1341 (“[T]he court may not impose conditions of 

parole[.]”).

probationer will obey a probation agent’s instruction to comply with a condition of 

mandatory supervision. In determining that a probationer has violated an order of 

probation by disobeying a probation agent’s instruction to comply with a condition of 

mandatory supervision, a court does not allow the executive branch to usurp the judiciary’s 

powers, but instead properly exercises the judiciary’s power to conclude that the probation 

agent’s instruction was lawful.

 For the above reasons, a probation agent’s instruction to comply with a condition of 

mandatory supervision is consistent with the separation of powers.
