The Latin maxim de minimis non curat lex translates to “the law does not concern itself with trifles,” and courts treat it as a working doctrine that lets judges and regulators dismiss matters so minor that pursuing them would waste more resources than the harm warrants. It functions as a filter across civil, criminal, employment, tax, and copyright law: if a violation is small enough, the legal system moves on.
How Courts Decide Something Is Trivial
There is no single test. The analysis shifts with context, and a dollar figure that counts as trivial in one setting can be actionable in another. A few factors recur almost everywhere the doctrine appears.
Financial proportionality carries the most weight. When the cost of litigating dwarfs what is at stake, courts are more willing to call the claim a trifle. A breach-of-contract suit over a few dollars would consume thousands in court time and attorney fees for a recovery that barely registers. Courts also weigh the degree of actual harm. A scratch on a car bumper is technically property damage, but no reasonable court will devote a docket slot to it.
Public interest can override both. Even a financially small case may proceed if it raises a novel legal question or could set precedent affecting many people. A minor environmental violation with broader compliance implications is the kind of case judges will hear despite its scale. That discretion is what keeps the doctrine from becoming a blanket shield for anyone who causes small harms repeatedly.
Civil Lawsuits
The doctrine appears most often in civil litigation, where it spares courts from claims whose remedy would cost more than the injury. Minor breaches of contract, negligible property damage, and tiny financial discrepancies are the usual candidates for dismissal.
There is no hard cutoff. A court asks about the relationship between the parties, whether the conduct was deliberate, and whether allowing the claim to proceed would invite a flood of similar suits. A landlord suing a tenant over a two-dollar overpayment would almost certainly be dismissed. A class action aggregating thousands of two-dollar overcharges across a customer base tells a different story, because the total harm and the pattern of conduct turn a trivial individual claim into something substantial.
The question is never just “how much?” but “how much relative to what?”
Criminal Cases and the Model Penal Code
The defense is less common in criminal law but far from irrelevant. The Model Penal Code, which has shaped criminal statutes across a majority of states, addresses it directly. Under MPC Section 2.12, a court can dismiss a criminal prosecution on any of three grounds:
- Customary tolerance. The conduct fell within a range society generally accepts and the person affected did not object. A neighbor cutting across a yard to reach the sidewalk is the classic example.
- Trivial harm. The conduct either did not cause the harm the law was designed to prevent or caused so little of it that conviction would be disproportionate. Shoplifting a single grape fits here.
- Legislative intent. The circumstances are so unusual that the legislature could not have intended the law to apply. A court using this ground must file a written explanation.
Prosecutorial discretion is the more common route by which minor offenses get filtered out before they reach a courtroom. Prosecutors routinely decline to bring charges for trivial infractions, especially when the offender has no prior record and no real harm resulted. It is not formally a de minimis ruling, but it serves the same purpose.
Unpaid Work Time Under the FLSA
One of the most consequential applications for ordinary workers involves unpaid time under the Fair Labor Standards Act. Federal regulations allow employers to disregard small amounts of time worked beyond scheduled hours, but the rule is narrower than many employers realize.
Under 29 CFR 785.47, employers may leave uncompensated only “insubstantial or insignificant periods of time” that cannot, as a practical matter, be precisely recorded for payroll purposes.1eCFR. 29 CFR 785.47 – Where Records Show Insubstantial or Insignificant Periods of Time The regulation limits this to uncertain periods of a few seconds or minutes, and only where failing to count the time is justified by workplace realities. An employer cannot use the de minimis label to skip paying for time it can actually track.
Courts have drawn clear lines. A federal appeals court held that as little as ten minutes of daily unpaid work is not de minimis, and another ruled that even one dollar per week in unpaid compensation is “not a trivial matter to a workingman.”1eCFR. 29 CFR 785.47 – Where Records Show Insubstantial or Insignificant Periods of Time The Department of Labor reinforces that employers cannot set artificial time limits below which they simply stop counting. The analysis turns on how often the extra work happens and whether it is part of the job the employee was hired to do.2U.S. Department of Labor. FLSA Hours Worked Advisor – Recording Hours Worked
If you are regularly spending extra minutes on the clock before or after a shift, your employer likely owes you for that time.
Tax Law Applications
Tax law contains some of the most concrete and dollar-specific applications of the doctrine. The IRS uses it to spare both taxpayers and the agency from accounting for amounts too small to matter.
Fringe Benefits
Under Internal Revenue Code Section 132(a)(4), employers can provide small perks to employees without triggering taxable income. A de minimis fringe benefit is one so small that accounting for it would be unreasonable or impractical, considering both its value and how often it is provided. Common examples include occasional office snacks and coffee, holiday gifts, personal use of a company photocopier, and employer-provided group-term life insurance of $2,000 or less for a spouse or dependent. The IRS has ruled that items exceeding $100 in value are not de minimis, even under unusual circumstances.3IRS. De Minimis Fringe Benefits One wrinkle worth noting: if a benefit is too large to qualify, the entire value becomes taxable, not just the amount above some threshold.
Business Expense Safe Harbor
The IRS also provides a de minimis safe harbor for businesses purchasing tangible property. Rather than capitalizing and depreciating small purchases, a business can deduct the full cost in the year of purchase if the amount is $2,500 or less per invoice. Businesses with audited financial statements can use a higher threshold of $5,000 per invoice.4IRS. Tangible Property Final Regulations This saves substantial recordkeeping on routine purchases.
Bond Discount
Investors run into the rule when buying bonds issued at a discount. If the total original issue discount is less than 0.25% of the face value multiplied by the number of years to maturity, the discount is treated as zero for tax purposes. On a 10-year bond with a $1,000 face value, any discount under $25 is de minimis and does not need to be reported as income annually.5IRS.

State Tax Immunity
The Supreme Court applied the doctrine to state taxation in Wisconsin Department of Revenue v. William Wrigley Jr. Co. (1992). The question was whether a company’s in-state activities were significant enough to forfeit its immunity from state taxation under federal law. The Court held that the issue turns on whether an activity establishes a “nontrivial additional connection” with the taxing state.6Justia. Wisconsin Dept. of Revenue v. William Wrigley Jr. Co., 505 U.S. 214 (1992) Activities like replacing stale gum, storing inventory, and resolving credit disputes were individually small but collectively crossed the line. Trivial acts can add up to something the law will not ignore.
Copyright and Music Sampling
Copyright is one of the most actively litigated arenas for de minimis arguments. When someone uses a small portion of a copyrighted work, the question is whether the copying is so minor it falls below the threshold of actionable infringement.
The Second Circuit set an influential standard in Ringgold v. Black Entertainment Television (1997). The case involved an artist’s copyrighted poster that appeared in the background of a television program for about 27 seconds across nine brief segments. The court held this was not de minimis, reasoning that the poster was clearly recognizable and visible enough for an ordinary viewer to identify it.7Justia. Ringgold v. Black Entertainment Television Inc., 126 F.3d 70 (2d Cir. 1997) For visual works, the analysis hinges on observability: how long the copied work appears, how much of it is visible, and whether camera angle and lighting make it recognizable.
Music sampling has produced a sharp split. The Sixth Circuit has ruled that any unauthorized sampling of a sound recording is infringing regardless of how small the clip is, effectively eliminating the de minimis defense for music producers in that jurisdiction. The Ninth Circuit rejected that approach and allows courts to apply the usual de minimis analysis to sampling cases. The same three-second drum loop could be lawful in California and infringing in Tennessee. The Supreme Court has not resolved the disagreement.
Origins and the Trend Toward Bright Lines
The phrase originates in Roman law, where it served the same function it does today: keeping courts from drowning in petty disputes. English common law adopted it, and it crossed into American jurisprudence without much controversy. Its logic is close to self-evident, which is why it rarely needed explicit codification until the Model Penal Code formalized it for criminal cases in the mid-twentieth century.
The modern shift has been toward specificity. Rather than leaving “trivial” as a subjective judgment call, legislatures and agencies have attached dollar thresholds and defined criteria. The IRS safe harbor, the FLSA regulation on insignificant work time, and comparable rules in other systems all reflect this trend.8HM Revenue & Customs. Partial Exemption Principles – De Minimis Bright-line rules reduce litigation over what counts as trivial, though courts still keep discretion at the margins. The principle has not changed in two thousand years; the machinery around it keeps getting more precise.
