A defendant in federal court can receive a two-level increase in the offense level for obstructing or attempting to obstruct the administration of justice.
The enhancement is found in U.S.S.G. § 3C1.1 and can substantially increase the advisory Federal Sentencing Guidelines range.
But not every false statement, unsuccessful defense, disputed piece of testimony, or refusal to cooperate constitutes obstruction of justice.
Section 3C1.1 requires willful obstructive conduct connected to the investigation, prosecution, or sentencing of the defendant’s offense or a closely related offense. The Sentencing Commission also expressly cautions that the enhancement is not intended to punish a defendant for exercising a constitutional right.
This distinction can become particularly important when the government claims that a defendant committed perjury, encouraged another witness to testify falsely, destroyed evidence, intimidated a witness, or otherwise interfered with a criminal investigation or prosecution.
Federal criminal defense attorney Michael J. Petro has more than 35 years of experience representing individuals in federal criminal trials, appeals, and sentencing proceedings involving the Federal Sentencing Guidelines.
What Is the U.S.S.G. § 3C1.1 Obstruction Enhancement?
The current Sentencing Guidelines provide for a two-level increase when the defendant willfully obstructed, impeded, or attempted to obstruct or impede the administration of justice concerning the investigation, prosecution, or sentencing of the offense, and the obstructive conduct related to the offense of conviction, relevant conduct, or a closely related offense.
Two levels can matter significantly.
Depending on the defendant’s offense level and criminal history category, the application of § 3C1.1 can substantially increase the advisory imprisonment range.
The enhancement may have an additional consequence, as obstruction may also affect whether the defendant receives a reduction for acceptance of responsibility under U.S.S.G. § 3E1.1.
The Conduct Must Be Willful
The word “willfully” is important.
Section 3C1.1 addresses intentional obstruction.
The Guidelines specifically caution courts that inaccurate testimony or statements can result from:
- Confusion;
- Mistake; or
- Faulty memory.
Accordingly, not every inaccurate statement reflects a willful attempt to obstruct justice.
This principle can become particularly important when the government seeks the enhancement based on allegedly false testimony.
There is a significant difference between:
being wrong
and
intentionally lying in an effort to obstruct justice.
What Conduct Can Trigger the Enhancement?
The Sentencing Commission provides a non-exhaustive list of conduct that can support the enhancement.
Examples include:
- Threatening or intimidating a witness, juror, or co-defendant;
- Unlawfully attempting to influence a witness;
- Committing, suborning, or attempting to suborn perjury;
- Destroying or concealing material evidence;
- Directing another person to destroy or conceal evidence;
- Producing false or altered documents during an investigation or judicial proceeding;
- Providing materially false information to a judge or magistrate judge;
- Providing materially false information to a probation officer concerning a presentence investigation; and
- Other conduct intended to obstruct the investigation, prosecution, or sentencing of the offense.
The examples are not exhaustive.
The actual facts determine whether § 3C1.1 applies.
Perjury Can Result in the Obstruction Enhancement
One of the most frequently litigated applications of § 3C1.1 involves alleged perjury by the defendant at trial.
A defendant has a constitutional right to testify.
That does not include a right to commit perjury.
But a guilty verdict does not automatically mean the defendant committed perjury merely because the defendant testified and the jury rejected the testimony.
The Supreme Court addressed this distinction in United States v. Dunnigan, 507 U.S. 87 (1993).
United States v. Dunnigan
In Dunnigan, the Supreme Court held that an obstruction enhancement can constitutionally be imposed when a defendant commits perjury.
But the Court required more than the simple fact that the jury disbelieved the defendant.
For purposes of the enhancement, the sentencing court must determine that the defendant gave false testimony concerning a material matter with willful intent, rather than as a result of confusion, mistake, or faulty memory.
That distinction protects the defendant’s right to testify while permitting a sentencing court to address actual perjury.
Losing at Trial Is Not the Same as Committing Perjury
Consider a defendant who testifies:
“I did not know drugs were inside the package.”
The jury convicts.
The verdict establishes that the jury rejected the defense sufficiently to find the defendant guilty beyond a reasonable doubt.
But the sentencing court should not simply reason:
“The jury convicted him, therefore he lied, therefore § 3C1.1 applies.”
The obstruction inquiry requires a determination that the testimony constituted willful, material falsehood—not merely that the jury did not believe the defendant.
That distinction is central to Dunnigan.
The Sentencing Judge Should Make Specific Findings
When the enhancement is based on perjury, defense counsel should carefully examine the sentencing court’s findings.
The preferred approach under Dunnigan is for the court to address the specific testimony and make findings encompassing the factual predicates necessary for perjury.
A generalized statement that:
“The defendant lied at trial”
may present a very different record from findings identifying the material false testimony and explaining why the court concludes it was intentionally false.
Specific findings also make meaningful appellate review possible.
The Defendant’s Right to Testify Cannot Itself Be Punished
The Guidelines expressly state that § 3C1.1 is not intended to punish a defendant for exercising a constitutional right.
The commentary gives important examples.
A defendant’s:
- Denial of guilt;
- Refusal to admit guilt;
- Refusal to provide information to a probation officer; or
- Refusal to plead guilty
does not, by itself, justify the obstruction enhancement.
The government therefore cannot use § 3C1.1 merely because a defendant exercised the right to trial.
Calling a Defense Witness Does Not Automatically Constitute Obstruction
A defendant also has a fundamental interest in presenting witnesses in support of the defense.
A difficult issue arises when a defense witness later gives testimony the government claims was false.
The fact that the defendant called the witness does not necessarily establish that the defendant suborned perjury.
There is an important difference between:
presenting testimony from a witness whose account the government disputes
and
knowingly arranging for a witness to give materially false testimony.
That distinction was at the center of a Seventh Circuit appeal handled by Attorney Michael J. Petro.
United States v. Charles Thomas
Attorney Petro represented Charles Thomas in United States v. Thomas, No. 15-1142 before the United States Court of Appeals for the Seventh Circuit.
Thomas had been prosecuted for his alleged role in a narcotics-trafficking organization.
At trial, Thomas represented himself and called co-defendant Domingo Blount as a defense witness.
Blount testified in a manner that supported Thomas’s defense and denied Thomas’s involvement in the conspiracy.
The jury nevertheless convicted Thomas. The district court later applied the § 3C1.1 obstruction enhancement based on the circumstances surrounding Blount’s testimony.
The Seventh Circuit ultimately affirmed the enhancement in a published August 15, 2016 decision.
The Defense Argument in Thomas
The defense position raised an important distinction under § 3C1.1:
False testimony by a defense witness does not automatically establish that the defendant knowingly procured it.
To treat a witness’s alleged perjury as obstruction by the defendant, there must be a factual basis connecting the defendant to the willful presentation or procurement of the false testimony.
Otherwise, a defendant could face an increased sentence merely because a witness called by the defense was later disbelieved.
That would create serious concerns about the right to present a defense.
What Does It Mean to Suborn Perjury?
Subornation of perjury generally involves knowingly procuring or inducing another person to commit perjury.
For § 3C1.1 purposes, the Guidelines expressly identify committing, suborning, or attempting to suborn perjury as conduct that can support the enhancement.
The critical factual issue is therefore not simply:
“Did the witness testify falsely?”
It is also:
“What did the defendant intentionally do to cause or procure that false testimony?”
The government must establish the defendant’s own obstructive conduct.
Witness Intimidation Can Trigger § 3C1.1
Another straightforward application involves witness intimidation.
The Guidelines specifically identify threatening, intimidating, or otherwise unlawfully influencing a witness, co-defendant, or juror as obstructive conduct.
Examples can include:
- Threatening a witness with violence;
- Directing another person to threaten a witness;
- Attempting to persuade a witness to give false testimony;
- Pressuring a witness not to cooperate;
- Attempting to cause a witness to disappear; or
- Offering improper benefits in exchange for false testimony.
Attempted obstruction can be enough.
The government does not necessarily have to prove that the attempt succeeded.
Destroying Evidence Can Result in the Enhancement
Destroying or concealing material evidence can also support § 3C1.1.
Modern cases frequently involve allegations that a defendant:
- Deleted text messages;
- Destroyed a cellphone;
- Deleted computer files;
- Shredded documents;
- Hid records;
- Destroyed surveillance footage; or
- Directed someone else to dispose of evidence.
But timing and intent matter.
The Guidelines can reach certain conduct occurring even before an investigation formally begins when the conduct was purposefully calculated and likely to thwart investigation or prosecution of the offense.
That rule can become particularly important in fraud and white-collar cases involving document destruction.
Not Every Deleted Document Is Obstruction
The mere fact that evidence was deleted or destroyed does not necessarily resolve the issue.
The government still must establish the required obstructive intent and connection to the investigation, prosecution, or sentencing.
For example, routinely deleting old emails pursuant to an established document-retention policy presents a different issue from intentionally destroying incriminating records after learning that federal agents have issued subpoenas.
Context matters.
False Documents Can Trigger the Enhancement
Creating or producing false evidence during an investigation can provide a strong basis for § 3C1.1.
Examples might include:
- Fabricated invoices;
- Altered business records;
- False contracts;
- Backdated documents;
- Falsified accounting records;
- Manufactured correspondence; or
- Other evidence created to mislead investigators or the court.
The issue is not merely whether a document contains an error.
The question is whether the defendant intentionally used false evidence to obstruct or impede the administration of justice.
False Statements to Law Enforcement Do Not Always Qualify
This is another important limitation.
The Guidelines identify making false statements to law-enforcement officers, not under oath, as conduct that ordinarily does not warrant the § 3C1.1 adjustment unless the circumstances satisfy a separately identified covered category.
That means a defendant’s lie to an investigating agent does not automatically result in two additional offense levels.
The specific circumstances and effect of the false statement matter.
Giving a False Name at Arrest Does Not Automatically Qualify
Similarly, providing a false name or identification document at arrest ordinarily does not trigger § 3C1.1 unless it actually resulted in a significant hindrance to the investigation or prosecution.
This illustrates an important feature of the Guideline.
Not every effort to avoid detection or responsibility is treated identically.
The Sentencing Commission distinguishes between conduct warranting the formal two-level adjustment and less serious conduct that may be considered in other aspects of sentencing.
Fleeing From Arrest Ordinarily Is Not § 3C1.1 Obstruction
Simply avoiding or fleeing from arrest is also listed among conduct that ordinarily does not warrant the obstruction adjustment.
Different Guidelines provisions may apply when flight creates other risks.
For example, U.S.S.G. § 3C1.2 addresses reckless endangerment during flight.
Defense counsel should therefore identify the correct Guideline rather than assuming all evasive conduct constitutes obstruction under § 3C1.1.
Materiality Matters
The Guidelines define information as material when, if believed, it would tend to influence or affect the issue under determination.
This concept matters in cases involving:
- Perjury;
- False statements to the court;
- False information provided during a presentence investigation; and
- Fabricated evidence.
An immaterial error should not automatically be treated as an obstruction.
The government should identify why the alleged falsehood mattered to the proceeding.
Obstruction During the Presentence Investigation
Section 3C1.1 can apply to conduct occurring during sentencing, not merely during the criminal investigation or trial.
Providing materially false information to a probation officer regarding the Presentence Investigation Report may support the enhancement.
But again, not every inaccurate answer qualifies.
The Guidelines distinguish materially false information from incomplete or misleading information that does not rise to the required level.
Defense counsel should examine exactly what was said, whether it was material, and whether it was intentionally false.
Obstruction and Acceptance of Responsibility
The interaction between § 3C1.1 and U.S.S.G. § 3E1.1 can make the obstruction enhancement particularly costly.
Section 3E1.1 permits reductions for acceptance of responsibility.
The Guidelines commentary explains that conduct resulting in an obstruction enhancement ordinarily indicates that the defendant has not accepted responsibility.
But the rule is not absolute.
The Commission recognizes that there may be extraordinary cases in which both the obstruction adjustment and an acceptance-of-responsibility reduction apply.
The Practical Effect Can Exceed Two Levels
This means the practical sentencing effect of an obstruction finding can sometimes be much greater than the two levels added under § 3C1.1 itself.
A defendant might face:
+2 levels for obstruction
and also lose:
2 or 3 levels for acceptance of responsibility.
Depending upon the circumstances, the difference between the competing calculations can be substantial.
That makes a disputed obstruction enhancement an important sentencing issue.
A Guilty Plea Does Not Automatically Prevent an Obstruction Enhancement
A defendant can plead guilty and still receive § 3C1.1.
For example, a defendant might:
- Destroy evidence before pleading guilty;
- Threaten a witness;
- Attempt to fabricate evidence;
- Provide materially false information during sentencing; or
- Engage in other qualifying obstructive conduct.
The guilty plea does not erase earlier obstruction.
Conversely, pleading guilty does not automatically establish acceptance of responsibility. The Guidelines make clear that a guilty plea is significant evidence of acceptance, but it does not create an automatic entitlement to the reduction.
Obstruction Before an Investigation Begins
Another important feature of the current Guideline is that obstructive conduct can sometimes occur before the government formally begins its investigation.
The commentary provides that pre-investigation conduct may qualify when it was purposefully calculated and likely to thwart the investigation or prosecution of the offense.
This can arise in cases involving:
- Fraudulent recordkeeping;
- Evidence destruction;
- Cover stories;
- Concealment schemes; or
- Efforts to prevent anticipated detection.
The government still must establish the required relationship between the conduct and the offense.
The Enhancement Can Apply to a Closely Related Case
Section 3C1.1 is not necessarily limited to obstruction occurring in the defendant’s own proceeding.
The current Guideline also encompasses obstructive conduct related to a closely related offense, including, as the commentary explains, the co-defendant’s case.
That means efforts to interfere with the prosecution of a co-defendant can potentially create sentencing consequences in the defendant’s own case.
The Government Must Prove the Enhancement
At federal sentencing, the government generally bears the burden of establishing facts supporting an aggravating Guidelines adjustment by a preponderance of the evidence.
Defense counsel should therefore object specifically when the Presentence Investigation Report recommends § 3C1.1 without an adequate factual basis.
A useful objection should identify:
- The conduct the government claims was obstructive;
- What evidence supports that allegation;
- Whether the conduct was willful;
- Whether any alleged statement was actually false;
- Whether it was material;
- Whether the defendant personally caused the conduct;
- Whether the conduct was connected to the offense; and
- Whether the Guideline commentary identifies the conduct as ordinarily covered or ordinarily excluded.
The word “obstruction” is a legal conclusion.
The sentencing court needs facts.
The Presentence Investigation Report Should Be Examined Carefully
A PSR may state:
“The defendant obstructed justice by providing false testimony.”
That conclusion should be tested.
What testimony?
What exactly was false?
Why was it false?
Was the statement material?
What evidence establishes willfulness?
Could the discrepancy have resulted from confusion or faulty memory?
Did the sentencing court make the findings required by the governing law?
These questions can determine whether the two-level adjustment applies.
The Enhancement Should Not Punish a Legitimate Defense
The Sentencing Commission’s express warning that § 3C1.1 is not intended to punish the exercise of constitutional rights is significant.
A defendant may:
- Plead not guilty;
- Require the government to prove its case;
- Cross-examine witnesses;
- Present evidence;
- Call defense witnesses;
- Testify;
- Decline to testify;
- Challenge the government’s evidence; and
- Contest the Presentence Investigation Report.
Those actions do not themselves constitute obstruction.
The line is crossed when the defendant engages in willful obstructive conduct meeting the requirements of § 3C1.1.
Challenging § 3C1.1 Requires a Fact-Specific Defense
Obstruction cases can look very different from one another.
A perjury allegation requires a different analysis from witness intimidation.
Witness intimidation differs from destruction of evidence.
Destruction of evidence differs from false information provided during the presentence investigation.
Defense counsel should therefore avoid treating § 3C1.1 as a single generic enhancement.
The defense should identify the precise conduct alleged and then apply the Guideline and governing precedent to that conduct.
The Guidelines Range Is Still Advisory
Even when § 3C1.1 properly applies, the resulting Guidelines range remains advisory.
After calculating the Guidelines, the sentencing court must consider the statutory factors under 18 U.S.C. § 3553(a) and impose a sentence sufficient, but not greater than necessary, to accomplish the statutory sentencing purposes.
Thus, the defense may have two separate arguments:
First: the obstruction enhancement should not apply.
Second: even if it technically applies, the resulting Guidelines sentence is greater than necessary under § 3553(a).
Both arguments can be important.
The Central Question Under § 3C1.1
The obstruction enhancement should not be reduced to the question:
“Did the defendant do something the government disliked?”
The proper inquiry is more demanding.
Defense counsel should ask:
What exactly did the defendant do?
Was the conduct willful?
Was it actually obstructive?
Was any alleged falsehood material?
Was the conduct connected to the investigation, prosecution, sentencing, or a closely related offense?
Is the government attempting to punish the defendant for exercising a constitutional right?
Does the Guidelines commentary identify this conduct as ordinarily covered—or ordinarily not covered?
Those questions determine whether the two-level adjustment is appropriate.

Michael J. Petro has more than 35 years of criminal defense experience representing individuals in federal criminal trials, appeals, and sentencing proceedings.
An obstruction-of-justice enhancement can substantially affect the Federal Sentencing Guidelines calculation, particularly when it also threatens the defendant’s eligibility for a reduction for acceptance of responsibility.
Defense counsel should carefully examine the government’s evidence, the Presentence Investigation Report, the required element of willfulness, materiality where applicable, and the sentencing court’s factual findings.
