First, read the judgment and confirm it imposed probation. Supervised release after prison is a different kind of supervision. If the judgment does impose federal probation and you receive a violation notice, summons, or arrest, give your lawyer the written probation conditions, the allegation, and the related records right away. The court must address the allegation under Federal Rule of Criminal Procedure 32.1; the possible response is addressed in 18 U.S.C. § 3565. A first alleged violation does not guarantee a warning or a lesser result.
Start with the notice and written conditions
Compare the notice or petition with the judgment and every written condition or later modification. Federal law requires a written statement of conditions clear enough to guide conduct. (18 U.S.C. § 3563(d).) Rule 32.1 provides for notice of the alleged violation and counsel rights at the initial appearance. Mark the condition the government says was violated, the specific conduct and dates alleged, and what part you believe is mistaken or incomplete. Give counsel records that support or contradict the allegation, such as the judgment, written conditions, probation-officer communications, test or treatment records, and any summons or warrant. Preserve the originals and follow the court’s instructions; do not change or discard records.
If the allegation concerns new conduct, there may also be a separate criminal case. Ask counsel to track the violation proceeding and any new charge separately; do not assume one case automatically decides the other.
The hearings answer different questions
Rule 32.1 sets out stages rather than one universal hearing deadline:
| Stage | What to expect |
|---|---|
| Initial appearance | The magistrate tells you the alleged violation and advises you of the right to counsel. If you receive a summons, the rule provides for the initial appearance process as well. |
| Preliminary hearing, if you are in custody | Unless waived, a prompt hearing addresses whether there is probable cause to believe a violation occurred. The rule provides for your appearance, evidence, and the opportunity to question an adverse witness on request, subject to its stated interest-of-justice exception. This is not the final decision on revocation. |
| Release while the case is pending | If you seek release before the revocation hearing, Rule 32.1 places on you the burden to show by clear and convincing evidence that you are not likely to flee or pose a danger. That is an interim-release burden, not the final standard for deciding the alleged violation. |
| Revocation hearing | The hearing must occur within a reasonable time unless waived. The rule provides for written notice, disclosure of adverse evidence, your appearance and opportunity to present evidence and question adverse witnesses subject to its exception, counsel, and an opportunity to speak in mitigation. The rule does not set one fixed number of days for every case. |
Rule 32.1 states probable cause for the preliminary hearing and a clear-and-convincing burden for interim release; neither Rule 32.1 nor § 3565 states a numeric final proof standard for a federal probation violation. Ask counsel what standard governs the final hearing in your case. The interim-release burden answers a different question. (Rule 32.1; 18 U.S.C. § 3565.)
Possible court responses
After the Rule 32.1 hearing, § 3565(a) allows the court to continue probation, with possible changes or an extension of conditions, or to revoke probation and resentence under the federal sentencing provisions. The facts, written conditions, and applicable sentencing rules matter; a policy table does not determine the outcome by itself. (18 U.S.C. § 3565(a).)
Section 3565(b) identifies specific circumstances that require revocation and a sentence including imprisonment: unlawful controlled-substance possession, prohibited firearm possession, refusal to comply with required drug testing, or more than three positive tests for illegal controlled substances in one year. The testing cross-reference in § 3565(b)(3) points to § 3563(a)(4), while current § 3563 numbers drug testing at subsection (a)(5). Section 3563(e) sets conditions for confirming a disputed positive test when imprisonment is possible and directs the court to consider whether appropriate treatment is available as an exception when acting on a failed test under subsection (a)(5). A single positive test does not meet the separate more-than-three-positives trigger; a disputed result may require confirmation. Ask counsel to review the exact written condition, the test or refusal record, and the applicable statutory language. (18 U.S.C. § 3565(b); 18 U.S.C. § 3563(a)(5), (e).)
For federal probation imposed for a felony or Class A misdemeanor, Chapter 7, Part B of the 2025 U.S. Sentencing Guidelines contains policy statements about violation grades and possible responses. They are not a guaranteed sentence or a substitute for § 3565. The first alleged incident is relevant history, not a safe harbor. Part C addresses supervised release instead; counsel should check the original judgment, alleged conduct and statutory limits before estimating a probation range. (2025 Guidelines Manual, Chapter 7.)
