Both false swearing and perjury involve lying under oath, but they differ in context and requirements. Article 131 Perjury specifically addresses false statements made in judicial or quasi-judicial proceedings where the testimony is material to the matter being decided. Article 134 False Swearing addresses false statements made under any lawful oath, even outside formal proceedings. Perjury is the more specific and serious offense; false swearing is broader but typically less severely punished.
The Proceeding Distinction
Article 131 Perjury requires:
A competent tribunal, officer, or proceeding
An oath properly administered
A false statement that is material
The formal context of judicial proceedings
Article 134 False Swearing covers:
Any lawful oath
False statements in any sworn context
No requirement for a judicial proceeding
No materiality requirement
Different Severity
Perjury is more serious because:
It corrupts judicial proceedings specifically
It affects decisions that have legal consequences
It undermines the justice system
It’s a specifically enumerated offense
False swearing is broader because:
It covers any sworn false statement
It reaches beyond courtroom contexts
It addresses general oath violations
It’s charged under Article 134’s general provisions
Article 131: Perjury Elements
Perjury requires:
Lawful oath. A proper oath administered by someone with authority.
Competent tribunal or proceeding. A court-martial, Article 32 hearing, or similar formal proceeding.
False statement. The witness said something untrue.
Knowledge of falsity. The witness knew it was false.
Materiality. The false statement was relevant to the matter being decided.
All elements must be satisfied; missing any one defeats the perjury charge.
Article 134: False Swearing Elements
False swearing requires:
Lawful oath. Any valid oath, not limited to judicial proceedings.
False statement. An untrue statement made under that oath.
Knowledge of falsity. The person knew the statement was false.
Prejudice or discredit. The conduct was prejudicial or service-discrediting.
No materiality requirement and no specific proceeding required.
The Materiality Difference
For perjury:
The lie must be material (relevant to the decision)
Immaterial lies under oath might not be perjury
The lie must matter to the proceeding
For false swearing:
No materiality requirement
Any false statement under oath can qualify
The relevance of the lie doesn’t matter
This means some lies under oath that aren’t perjury (because immaterial) could still be false swearing.
Typical Fact Patterns
Clear perjury (Article 131):
At a court-martial, a witness testifies falsely that they didn’t see the accused at the crime scene. Material lie in a judicial proceeding.
During an Article 32 hearing, a witness falsely denies knowledge of key evidence. False testimony in a formal proceeding on a material matter.
Clear false swearing (Article 134):
A service member signs a sworn statement claiming they weren’t at a party, when they were. Sworn statement context, not a judicial proceeding.
Someone takes an oath during an administrative inquiry and lies about their involvement. False statement under oath outside a court.
A service member provides a false sworn affidavit for an administrative process. False swearing in a non-judicial context.
The distinction:
Lying at a court-martial about material facts: Perjury (Article 131)
Lying in a sworn statement to investigators: Could be perjury if used in a proceeding; otherwise false swearing (Article 134)
When False Swearing Becomes Perjury
The same false statement might be either offense:
At the time made:
If made during a judicial proceeding: Perjury (if material)
If made under oath but outside proceedings: False swearing
When later used:
A false sworn statement might become perjury evidence if introduced in a proceeding
The original making was false swearing; the proceeding context may add perjury implications
Punishment Comparison
Article 131 (Perjury):
Dishonorable discharge, forfeiture of all pay and allowances, confinement for 5 years
The specific offense carries significant punishment
Article 134 (False Swearing):
Dishonorable discharge, forfeiture of all pay and allowances, confinement for 3 years
Less than perjury, reflecting the less formal context
Both are serious, but perjury’s attack on the justice system warrants harsher potential punishment.
The Oath Requirement
Both require a lawful oath:
Who can administer oaths:
Military judges
Notaries
Certain officers authorized by regulation
Investigation officers
What makes an oath lawful:
Proper authority of the person administering it
Correct form
Understanding by the person taking it
Without a proper oath, neither offense can be charged.
Defenses
For perjury:
The statement was true
No oath was administered
The proceeding wasn’t competent
The statement wasn’t material
No knowledge of falsity
For false swearing:
The statement was true
No oath was administered
No knowledge of falsity
The conduct wasn’t prejudicial or discrediting
Relationship to False Official Statements
Article 107 (False Official Statements) covers lying in official contexts without an oath. The relationship:
No oath: Article 107 false official statement
Oath, no proceeding: Article 134 false swearing
Oath in proceeding, material: Article 131 perjury
The oath and proceeding context determine which article applies.
Practical Implications
When making sworn statements:
Understand you’re under oath
Tell the truth completely
Clarify questions you don’t understand
Don’t guess or speculate beyond your knowledge
When testifying:
Everything you say is under oath
Material lies are perjury
The consequences of lying far exceed any benefit
Frequently Asked Questions
If I lied in a sworn statement but it wasn’t important to the investigation, can I still be charged?
Yes. False swearing under Article 134 doesn’t require materiality. Any false statement made under oath can support false swearing charges regardless of whether the lie mattered to the investigation. If the statement is later used in a judicial proceeding and the lie was material to that proceeding, perjury might also apply. The “it wasn’t important” defense doesn’t work for false swearing because materiality isn’t an element. The fact that you lied under oath is enough, and prosecutors decide whether to charge based on the circumstances.
What’s the difference between false swearing and lying to investigators?
The oath is the key distinction. Lying to investigators without being under oath might be false official statement (Article 107) or obstruction of justice (Article 134), but not perjury or false swearing. Both perjury and false swearing require that you were under oath when you lied. If investigators don’t put you under oath, your lies are still potentially criminal, but under different articles. If you sign a sworn statement or testify under oath, false swearing or perjury applies depending on the context.
If I said something under oath that I believed was true but turned out to be wrong, is that perjury or false swearing?
Neither. Both perjury and false swearing require knowledge of falsity. If you genuinely believed your statement was true when you made it, you didn’t knowingly lie. Being wrong isn’t the same as lying. However, this defense is evaluated carefully. If you stated something as fact without actually knowing, or if evidence shows you must have known the truth, the claim of genuine belief becomes less credible. The question is whether you knew the statement was false at the time you made it, not whether it turned out to be inaccurate later.
