SILFREDO CASTILLO CANALES OPINION BY JUSTICE TERESA M. CHAFIN SILFREDO CASTILLO CANALES APRIL 10, 2025
v. Record No. 230934
FROM THE COURT OF APPEALS OF VIRGINIA
These appeals involve the interpretation of certain provisions of Code § 19.2-306.1, a
statute that places limitations on the sentence that a court may impose when an individual
violates the terms of his probation. For the following reasons, we affirm the judgment of the
Court of Appeals in part, reverse the judgment of the Court of Appeals in part, and reinstate the
judgment of the Circuit Court of Arlington County.
I. MATERIAL FACTS AND PROCEEDINGS
A. THE PROBATION VIOLATIONS
In 2017, Silfredo Antonio Castillo Canales (“Castillo Canales”) was convicted of
statutory burglary and grand larceny. Castillo Canales was sentenced to five years of
incarceration for each conviction, with the sentences running concurrently. The circuit court
suspended two years and six months of each sentence and placed Castillo Canales on supervised
probation.
Castillo Canales began supervised probation upon his release from incarceration in 2019.
On October 29, 2021, Castillo Canales’ probation officer filed a major violation report
addressing numerous probation violations. The major violation report asserted that Castillo Canales: failed two drug screens by testing positive for cocaine, missed multiple appointments
with his probation officer, failed to appear for multiple scheduled drug screens, failed to comply
with the requirements of his drug treatment program, and failed to make restitution payments.
The major violation report also noted that Castillo Canales had been charged with new criminal
offenses.
The violations addressed in the major violation report occurred over approximately five
months. During this time period, Castillo Canales intermittently attempted to comply with the
requirements of probation. Consequently, Castillo Canales’ probation violations were often
separated by periods of compliance. The following timeline outlines the conduct that is pertinent
to this appeal:
• 5/25/21: Castillo Canales failed a drug screen, testing positive for cocaine.
• 6/2/21: Castillo Canales failed to appear for a drug screen.
• 6/4/21: Castillo Canales had a phone conversation with his probation officer.
• 6/15/21: Castillo Canales passed a drug screen.
• 7/7/21: Castillo Canales passed a drug screen.
• 7/20/21: Castillo Canales passed a drug screen.
• 8/3/21: Castillo Canales failed to appear for a drug screen.
• 8/3/21: Castillo Canales had a phone conversation with his probation officer.
• 8/11/21: Castillo Canales passed a drug screen.
• 8/11/21: Castillo Canales met with his probation officer in person.
• 8/19/21: Castillo Canales failed to appear for a drug screen.
• 9/10/21: Castillo Canales passed a drug screen.
• 9/17/21: Castillo Canales failed to attend an appointment with his probation officer.
2 • 9/23/21: Castillo Canales failed to appear for a drug screen.
• 9/30/21: Castillo Canales failed to attend an appointment with his probation officer.
• 9/30/21: Castillo Canales had a phone conversation with his probation officer.
• 10/5/21: Castillo Canales failed to appear for a drug screen.
• 10/7/21: Castillo Canales failed to attend an appointment with his probation officer.
• 10/12/21: Castillo Canales failed a drug screen, testing positive for cocaine.
B. THE CIRCUIT COURT PROCEEDINGS
On January 28, 2022, the circuit court held a hearing to address the status of the probation
revocation proceedings. At this hearing, the circuit court advised the parties that it intended to
address the violations set forth in the major violation report in separate hearings. The circuit
court explained that the violations were separate and discrete events that occurred over several
months.
Castillo Canales objected to the circuit court’s intended course of action. Relying on
Code § 19.2-306.1, Castillo Canales argued that the circuit court was required to consider all of
the violations set forth in the major violation report in the same hearing. Furthermore, Castillo
Canales asserted that the violations constituted a “single course of conduct” under Code
§ 19.2-306.1.
The circuit court rejected Castillo Canales’ position. Again, the circuit court explained
that the violations set forth in the major violation report were distinct and separate violations of
probation. Emphasizing the court’s discretion to manage its docket, the circuit court concluded
that the pertinent provisions of Code § 19.2-306.1 did not preclude the court from holding
separate hearings addressing the individual probation violations. The circuit court divided the
violations into separate cases and assigned a separate docket number to each case. The circuit
3 court explained that it would consider each case in a series of separate hearings, taking a brief
recess between the cases.
On March 11, 2022, the circuit court held a series of hearings concerning the pending
probation violations. Castillo Canales objected to the circuit court’s course of action at the outset
of each hearing. Castillo Canales, however, did not contest the factual bases of the violations.
At the conclusion of each hearing, the circuit court determined that Castillo Canales
violated the terms of his probation. Specifically, the circuit court concluded that Castillo Canales
violated the terms of his probation by: failing a drug screen on May 25, 2021 (Circuit Court
Case Nos. CR17000076-01 and CR17000077-01); failing a drug screen on October 12, 2021
(Circuit Court Case Nos. CR17000076-02 and CR17000077-02); failing to appear for a drug
screen on June 2, 2021 (Circuit Court Case Nos. CR17000076-03 and CR17000077-03); and
failing to appear for a drug screen on August 3, 2021 (Circuit Court Case Nos. CR17000076-04
and CR17000077-04). The circuit court revoked Castillo Canales’ suspended sentences in each
case but resuspended each sentence in its entirety.
On May 13, 2022, the circuit court held separate hearings concerning the remaining
probation violations. Castillo Canales renewed his previous objections at the outset of the
hearings. Castillo Canales also denied that he committed some of the violations at issue.
The circuit court overruled Castillo Canales’ objections, relying on the same rationale
that it applied in the previous hearings. After hearing testimony from a probation officer, the
circuit court concluded that Castillo Canales committed some of the pending violations.
Specifically, the circuit court, in separate hearings, determined that Castillo Canales violated the
terms of his probation by: failing to appear for a drug screen on August 19, 2021 (Circuit Court
Case Nos. CR17000076-05 and CR17000077-05); failing to appear for a drug screen on
4 September 23, 2021 (Circuit Court Case Nos. CR17000076-06 and CR17000077-06); and failing
to attend an appointment with his probation officer on September 17, 2021 (Circuit Court Case
Nos. CR17000076-08 and CR17000077-08). The circuit court revoked Castillo Canales’
suspended sentences in each case and resuspended all but 14 days of each sentence.
Cumulatively, the circuit court ordered Castillo Canales to serve 42 days of active incarceration. ∗
The circuit court concluded that Castillo Canales had not violated the terms of his
probation in other cases, dismissing the violations based on Castillo Canales’: failure to appear
for a drug screen on October 5, 2021 (Circuit Court Case Nos. CR17000076-07 and
CR17000077-07); failure to attend a meeting with his probation officer on September 30, 2021
(Circuit Court Case Nos. CR17000076-09 and CR17000077-09); and failure to attend a meeting
with his probation officer on October 7, 2021 (Circuit Court Case Nos. CR17000076-10 and
CR17000077-10). The circuit court continued the cases based on Castillo Canales’ new criminal
charges and took the remaining cases under advisement to permit Castillo Canales to pay
restitution and comply with the requirements of his drug treatment program.
C. THE COURT OF APPEALS PROCEEDINGS
Castillo Canales noted an appeal. Citing the pertinent provisions of Code § 19.2-306.1,
Castillo Canales asserted that the circuit court was required to consider all of the violations set
forth in the major violation report in the same hearing. Castillo Canales also argued that the
violations at issue arose from a “single course of conduct.” For these reasons, Castillo Canales
claimed that all of the violations should have been treated as a single technical violation under
∗ The circuit court ran the sentences imposed in each set of corresponding cases (Circuit Court Case Nos. CR17000076-05 and CR17000077-05; CR17000076-06 and CR17000077-06; CR17000076-08 and CR17000077-08) concurrently with each other, resulting in the imposition of 14 days of active incarceration for each set of corresponding cases—for a cumulative period of 42 days of active incarceration.
5 Code § 19.2-306.1. Castillo Canales argued that, therefore, the circuit court erred when it
imposed an active period of incarceration based on the violations.
The Court of Appeals affirmed the circuit court’s judgment in part, reversed the circuit
court’s judgment in part, and remanded the matter for further proceedings. Castillo Canales v.
Commonwealth, 78 Va. App. 353, 358 (2023). Addressing Castillo Canales’ first argument, the
Court of Appeals held that the pertinent provisions of Code § 19.2-306.1 did not require the
circuit court to consider all of the probation violations in the same hearing. Id. at 365-66. The
Court of Appeals noted that the plain language of the statute failed to impose such a requirement.
Id. at 366. Moreover, the Court of Appeals observed that the circuit court had broad discretion to
determine the manner in which it would address the pending violations. Id. at 365. Accordingly,
the Court of Appeals concluded that the circuit court could address the individual violations set
forth in the major violation report in separate hearings. Id. at 366.
Turning to Castillo Canales’ second argument, the Court of Appeals observed that Code
§ 19.2-306.1 does not provide a definition for the term “single course of conduct.” Id. at 368.
Therefore, the Court of Appeals relied on several dictionary definitions to define the term. Id.
Relying on Webster’s Third New International Dictionary, the Court of Appeals noted that the
term “course” refers to “an ordered continuing process, succession, sequence, or series.” Id.
(quoting Webster’s Third New International Dictionary 522 (2002)). Relying on Black’s Law
Dictionary, the Court of Appeals noted that the term “conduct” refers to “[p]ersonal behavior,
whether by action or inaction; the manner in which a person behaves.” Id. (quoting Black’s Law
Dictionary 369 (11th ed. 2019)). Combining these definitions, the Court of Appeals concluded
that a “single course of conduct” under Code § 19.2-306.1 “is an ordered continuing process,
succession, sequence, or series of acts or behavior.” Id.
6 Applying this definition, the Court of Appeals determined that the probation violations at
issue constituted two courses of conduct under Code § 19.2-306.1. Id. at 370. The Court of
Appeals explained that Castillo Canales’ failed drug screens were part of one course of conduct,
and that Castillo Canales’ failure to attend appointments and appear for drug screens were part of
another course of conduct. Id. at 369-70.
The Court of Appeals concluded that, since Castillo Canales’ probation violations were
parts of only two courses of conduct, Castillo Canales should have been sentenced as if he had
only committed two technical violations of probation. Id. at 370-71. Therefore, the Court of
Appeals determined that Castillo Canales could have only been sentenced to a maximum of 14
days of active incarceration. Id. at 371.
The Court of Appeals affirmed the circuit court’s judgment regarding the probation
violations that were addressed in the first set of hearings held on March 11, 2022 (Circuit Court
Case Nos. CR17000076-01 and CR17000077-01 through CR17000076-04 and CR17000077-
04). Id. at 371. As the circuit court did not impose any active incarceration in these cases, it did
not violate the sentencing limitations set forth in Code § 19.2-306.1 under the rationale adopted
by the Court of Appeals. Id. at 367. The Court of Appeals, however, reversed the circuit court’s
judgment regarding the challenged probation violations that were addressed in the second set of
hearings held on May 13, 2022 (Circuit Court Case Nos. CR17000076-05 and CR17000077-05;
CR17000076-06 and CR17000077-06; and CR17000076-08 and CR17000077-08). Id. at 371.
The Court of Appeals concluded that, since Castillo Canales only committed two technical
violations of probation, the circuit court erred when it ordered Castillo Canales to serve more
than 14 days of active incarceration. Id. at 370-71. The Court of Appeals remanded the matter
for resentencing consistent with its opinion. Id. at 371. These appeals followed.
7 II. ANALYSIS
Both the Commonwealth and Castillo Canales have challenged the judgment of the Court
of Appeals. Castillo Canales contends that the Court of Appeals erred by determining that Code
§ 19.2-306.1 did not require the circuit court to address all of the probation violations set forth in
the major violation report in the same hearing. Both parties challenge the Court of Appeals’
definition and application of the term “single course of conduct.” The Commonwealth argues
that the circuit court reasonably determined that the probation violations at issue were separate
and distinct events, and therefore, not part of a “single course of conduct” under Code
§ 19.2-306.1. Castillo Canales, however, maintains that all of the violations set forth in the
major violation report were part of a “single course of conduct” under the statute.
These arguments present issues of statutory interpretation that are subject to de novo
review. See, e.g., Commonwealth v. Delaune, 302 Va. 644, 655 (2023). However, the
underlying factual determinations of the circuit court are entitled to deference on appeal. See,
e.g., Hamilton v. Commonwealth, 217 Va. 325, 327 (1976) (explaining that a court’s factual
findings in a revocation proceeding will only be set aside upon a showing of an abuse of
discretion).
A. THE PERTINENT PROVISIONS OF CODE § 19.2-306.1
Code § 19.2-306.1 places limitations on the sentence that a court may impose when it
revokes a suspended sentence based on an enumerated “technical violation” of probation. See
Code §§ 19.2-306(C); 19.2-306.1(A) and (C). A probationer’s unauthorized use of a controlled
substance is a technical violation of probation under the statute. Code § 19.2-306.1(A)(vii). A
probationer’s failure to “report as instructed” by his probation officer also constitutes a technical
violation. Code § 19.2-306.1(A)(v).
8 A court may not impose a term of active incarceration based on a probationer’s first
technical violation. Code § 19.2-306.1(C). Furthermore, there is a statutory presumption against
the imposition of a term of active incarceration following a probationer’s second technical
violation. Id. A court may only impose up to 14 days of active incarceration based on a second
technical violation “if the court finds, by a preponderance of the evidence, that the defendant . . .
cannot be safely diverted from active incarceration through less restrictive means.” Id. In
contrast, a court may impose “whatever sentence might have been originally imposed for a third
or subsequent technical violation.” Id.
Pursuant to Code § 19.2-306.1(A), “[m]ultiple technical violations arising from a single
course of conduct or a single incident or considered at the same revocation hearing shall not be
considered separate technical violations for the purposes of sentencing pursuant to this section.”
The scope of this provision is at issue in the present case.
B. MULTIPLE REVOCATION HEARINGS UNDER CODE § 19.2-306.1
Castillo Canales contends that the circuit court should have considered all of the
probation violations set forth in the major violation report in the same revocation hearing.
Therefore, Castillo Canales argues that he should have been sentenced as though he had only
committed one technical violation of probation.
This argument is not supported by the text of Code § 19.2-306.1. The statute does not
require a court to address all of the probation violations that are set forth in a major violation
report in the same hearing. A court has broad discretion in a revocation proceeding. See, e.g.,
Delaune, 302 Va. at 658. While a court may address all pending probation violations in the same
hearing under Code § 19.2-306.1, the terms of the statute do not prohibit a court from addressing
individual probation violations in separate hearings.
9 We acknowledge that probation officers have a duty to report violations of probation to a
sentencing court. See Code § 53.1-145(1) and (5). A probation officer’s violation report often
triggers revocation proceedings. Nevertheless, the court ultimately decides whether to initiate
revocation proceedings and determines the manner in which the proceedings will be conducted.
“[I]t is the court and the court alone that . . . decides whether or not revocation proceedings shall
be initiated and, if initiated, what consequences will befall the individual who has violated his
conditions of release.” United States v. Bermudez-Plaza, 221 F.3d 231, 234 (1st Cir. 2000).
“The probation statutes are highly remedial and should be liberally construed to provide
trial courts a valuable tool for rehabilitation of criminals.” Grant v. Commonwealth, 223 Va.
680, 684 (1982). “[T]he power of the courts to revoke suspensions and probation . . . must not
be restricted beyond the statutory limitations.” Id.
“[W]e must . . . assume that the legislature chose, with care, the words it used when it
enacted the relevant statute, and we are bound by those words as we interpret the statute.”
Delaune, 302 Va. at 655 (quoting Supinger v. Stakes, 255 Va. 198, 206 (1998)). “This Court
may not construe the plain language of a statute ‘in a manner that amounts to holding that the
General Assembly meant to add a requirement to the statute that it did not actually express.’”
Jones v. Commonwealth, 296 Va. 412, 415 (2018) (quoting Commonwealth v. Amos, 287 Va.
301, 307 (2014)). In the present case, we cannot construe Code § 19.2-306.1 in a manner that
requires a court to address all pending probation violations in the same revocation hearing. To
do so would add a new requirement to the statute.
Code § 19.2-306.1 does not prohibit a court from addressing individual probation
violations that are set forth in the same major violation report in separate revocation hearings.
10 Accordingly, the circuit court did not err by addressing Castillo Canales’ probation violations in
separate hearings in this case.
C. A “SINGLE COURSE OF CONDUCT” UNDER CODE § 19.2-306.1
Under the pertinent provision of Code § 19.2-306.1, multiple technical violations of
probation arising from a “single course of conduct” are not treated as separate violations for
sentencing purposes—even if the violations are considered in separate revocation hearings. See
Code § 19.2-306.1(A). The Commonwealth maintains that the circuit court reasonably
determined that Castillo Canales’ probation violations did not arise from a “single course of
conduct” under Code § 19.2-306.1. Castillo Canales, however, contends that all of his probation
violations arose from a “single course of conduct” under the statute.
When interpreting a statute, “[o]ur primary objective is ‘to ascertain and give effect to
legislative intent,’ as expressed by the language used in the statute.” Delaune, 302 Va. at 655
(quoting Cuccinelli v. Rector & Visitors of the Univ. of Va., 283 Va. 420, 425 (2012)). “Words
in a statute are to be construed according to their ordinary meaning, given the context in which
they are used.” Grant, 223 Va. at 684. “[T]he plain, obvious and rational meaning of a statute is
always to be preferred to any curious, narrow or strained construction.” Delaune, 302 Va. at 655
(quoting City of Charlottesville v. Payne, 299 Va. 515, 527 (2021)).
Code § 19.2-306.1 does not define the term “single course of conduct.” By synthesizing
two dictionary definitions, the Court of Appeals reasonably defined a “single course of conduct”
as an “ordered continuing process, succession, sequence, or series of personal behavior.”
Castillo Canales, 78 Va. App. at 368. The Court of Appeals, however, failed to fully appreciate
the components of this definition.
11 Significantly, a “single course of conduct” is a “continuing” sequence of behavior. See
id. Black’s Law Dictionary defines “continuing” as “uninterrupted; persisting.” Black’s Law
Dictionary 402 (12th ed. 2024). Thus, a “single course of conduct” under Code § 19.2-306.1
refers to an uninterrupted and unbroken series of actions. The actions underlying a “single
course of conduct” are necessarily connected by time, place, and other circumstances.
The determination of whether a series of behavior constitutes a “single course of
conduct” under Code § 19.2-306.1 involves a fact-intensive inquiry. A court’s determination of
whether a series of probation violations constitutes a “single course of conduct” under the statute
is entitled to deference on appeal. See, e.g., Hamilton, 217 Va. at 327 (explaining that a court’s
factual findings in a revocation proceeding will only be set aside upon a showing of an abuse of
In the present case, the circuit court concluded that Castillo Canales violated the terms of
his probation by: failing a drug screen on May 25, 2021; failing to appear for a drug screen on
June 2, 2021; failing to appear for a drug screen on August 3, 2021; failing to appear for a drug
screen on August 19, 2021; failing to attend an appointment with his probation officer on
September 17, 2021; failing to appear for a drug screen on September 23, 2021; and failing a
drug screen on October 12, 2021.
The circuit court repeatedly invited Castillo Canales to present evidence establishing a
factual connection between the violations. Castillo Canales, however, did not present any
evidence at the revocation hearings to establish the particular circumstances surrounding the
violations at issue.
Based on the evidence presented at the revocation hearings, the circuit court could have
reasonably determined that the violations at issue were separate and distinct events. The
12 temporal sequence of the violations suggested that they were not part of a “single course of
conduct” under Code § 19.2-306.1. The violations occurred over approximately five months.
More importantly, the violations were not part of a continuous sequence of behavior. The
violations were separated by time periods that ranged from six days to over two months.
It is worth emphasizing that Castillo Canales complied with the terms of his probation at
certain times. These periods of compliance interrupted the underlying sequence of behavior that
is at issue in this case. Moreover, Castillo Canales’ probation history allowed the circuit court to
infer that the violations at issue arose from separate, calculated decisions. When explaining why
it decided to address the individual violations set forth in the major violation report in separate
hearings, the circuit court noted:
[Castillo Canales] is showing up occasionally in between, and breaking this up. . . . [H]e knows where to show up . . . [and] who to communicate with . . . [a]nd he is making decisions at each of these juncture points to not do it. . . . The facts show me that [Castillo Canales] is deciding to come and go when he wishes, maybe because he’s going to test positive, and he’s not going to show up.
Under the circumstances presented in this case, the circuit court permissibly determined
that Castillo Canales’ probation violations were separate and distinct events. Therefore, the
circuit court did not err by addressing the violations in separate revocation hearings. As the
sentencing limitations set forth in Code § 19.2-306.1 only applied to Castillo Canales’ first and
second technical violations of probation, see Code § 19.2-306.1(C), the circuit court could
impose more than 14 days of active incarceration for the violations that were addressed in the set
of hearings held on May 13, 2022.
13 III. CONCLUSION
In summary, we conclude that Code § 19.2-306.1 does not require a court to address all
of the probation violations that are set forth in a major violation report in the same revocation
hearing. Furthermore, we conclude that the circuit court permissibly determined that the
probation violations at issue were not part of a “single course of conduct” under Code
We affirm the judgment of the Court of Appeals in part, reverse the judgment of the
Court of Appeals in part, and reinstate the judgment of the circuit court. We affirm the judgment
of the Court of Appeals to the extent that it affirmed the circuit court’s judgment regarding the
probation violations that were addressed in the hearings held on March 11, 2022 (Circuit Court
Case Nos. CR17000076-01 and CR17000077-01 through CR17000076-04 and CR17000077-
04). However, we reverse the judgment of the Court of Appeals to the extent that it reversed the
circuit court’s judgment regarding the probation violations that were addressed in the hearings
held on May 13, 2022, and we reinstate the circuit court’s judgment in these cases (Circuit Court
Case Nos. CR17000076-05 and CR17000077-05; CR17000076-06 and CR17000077-06; and
CR17000076-08 and CR17000077-08).
Affirmed in part, reversed in part, and reinstated.
