De minimis is a Latin expression meaning "pertaining to minimal things", normally in the terms de minimis non curat praetor ("The praetor does not concern himself with trifles") or de minimis non curat lex ("The law does not concern itself with trifles"), a legal doctrine by which a court refuses to consider trifling matters. Queen Christina of Sweden (r. 1633–1654) favoured the similar Latin adage, aquila non capit muscās (the eagle does not catch flies).
The legal history of de minimis dates back to the 15th century.
The general term has come to have a variety of specialised meanings in various contexts as shown below, which indicate that beneath a certain low level a quantity is regarded as trivial, and treated commensurately.
Examples of application of the de minimis rule
Taxation
Under U.S. tax rules, the de minimis rule governs the treatment of small amounts of market discount. Under the rule, if a bond is purchased with a small amount of market discount (an amount less than 0.25% of the face value of a bond times the number of complete years between the bond's acquisition date and its maturity date) the market discount is considered to be zero and the discount on the bond will be considered to be a capital gain upon the bond's disposition or redemption rather than ordinary income. Under Internal Revenue Service guidelines, the de minimis rule can also apply to any benefit, property, or service provided to an employee that has so little value that reporting for it would be unreasonable or administratively impracticable; for example, use of a company photocopier to copy personal documents – see de minimis fringe benefit. Cash is not excludable, regardless of the amount.
Specifically in U.S. State income tax, de minimis refers to the point at which withholdings should be initiated for a nonresident working in a state which taxes personal income. Not all U.S. states levy income taxes, and there's little consistency among nonresident de minimis standards for those that do. Some states base de minimis on the number of days worked (although the definition of what counts as a workday has been controversial), others on the dollars earned or a percentage of total income derived from work in the state, still others using a combination of methods. These inconsistencies have led to repeated attempts to pass the so-called Mobile Workforce State Income Tax Simplification Act without success.
European Union usage
According to European Union regulations, de minimis "state aid" is any amount of aid up to the de minimis ceiling of €200,000 provided from state funds to a business enterprise over a rolling three-year period. For businesses in the land transport sector, the de minimis ceiling is €100,000. If a business receives more than the de minimis ceiling amount of aid, it is subject to a different set of regulations.
Under European Union competition law, some agreements infringing Article 101(1) of the Treaty on the Functioning of the European Union (formerly Article 81(1) of the EC Treaty) are considered to be de minimis and therefore accepted. Horizontal agreement, that is one between competitors, will usually be de minimis where the parties' market share is 10% or less, and a vertical agreement, between undertakings operating at different levels of the market, where it is 15% or less.
Procurement of low value contracts is subject to limited regulation when its value falls below certain low thresholds.
Criminology and crime
In criminology, the de minimis or minimalist approach is an addition to a general harm principle. The general harm principle fails to consider the possibility of other sanctions to prevent harm, and the effectiveness of criminalization as a chosen option. Those other sanctions include civil courts, laws of tort and regulation. Having criminal remedies in place is seen as a "last resort" since such actions often infringe personal liberties – incarceration, for example, prevents the freedom of movement. In this sense, law making that places a greater emphasis on human rights, such as the European Convention on Human Rights, falls into the de minimis category. Most crimes of direct action (murder, rape, assault, for example) are generally not affected by such a stance, but do require greater justification in less clear cases.
The de minimis rule in North American drug law requires a usable quantity of the substance in question before charges can be brought, known as the minority rule.
