Laches (equity)

In common-law legal systems, laches (Template:IPAc-en Template:Respell, Template:IPAc-en; Law French: Template:Lang, Template:Lang, from Template:Langx) is a lack of diligence and activity in making a legal claim, or moving forward with legal enforcement of a right, particularly in regard to equity. It is an unreasonable delay that can be viewed as prejudicing the opposing party. When asserted in litigation, it is an equity defense, that is, a defense to a claim for an equitable remedy. It is often understood in comparison to a statute of limitations, a statutory defense, which traditionally is a defense to a claim "at law".

The person invoking laches is asserting that an opposing party has "slept on its rights", and that, as a result of this delay, circumstances have changed (witnesses or evidence may have been lost or no longer available, etc.), such that it is no longer a just resolution to grant the plaintiff's claim. Laches is associated with the maxim of equity: "Equity aids the vigilant"Template:Sndnot those who sleep on their rights. Put another way, failure to assert one's rights in a timely manner can result in a claim being barred by laches.

Origin, definition, overview

Template:More citations needed section Laches is a legal term derived from the Old French laschesse, meaning "remissness" or "dilatoriness", and is viewed as the opposite of "vigilance".<ref name="bld">Template:Cite book</ref><ref>Template:OED</ref><ref>Template:Cite web</ref> The United States Supreme Court case Costello v.

Invoking laches is a reference to a lack of diligence and activity in making a legal claim, or moving forward with legal enforcement of a right, in particular with regard to equity, and so is an "unreasonable delay pursuing a right or claim, in a way that prejudices the [opposing] party".<ref name="bld" /> When asserted in litigation, it is an equitable defense, that is, a defense to a claim for an equitable remedy.<ref name="Little Bit of Laches">Template:Cite journal</ref> The essential element of laches is an unreasonable delay by the plaintiff in bringing the claim; because laches is an equitable defense, it is ordinarily applied only to claims for equitable relief (such as injunctions), and not to claims for legal relief (such as damages).<ref name="Little Bit of Laches" /> The person invoking laches is asserting that an opposing party has "slept on its rights", and that, as a result of this delay, witnesses or evidence may have been lost or no longer available, and circumstances have changed such that it is no longer just to grant the plaintiff's original claim;Template:Citation needed hence, laches is associated with the maxim of equity: Template:Lang ("Equity aids the vigilant, not the sleeping ones [that is, those who sleep on their rights]").<ref name="Ibrahim" >Template:Cite journal</ref> Put another way, failure to assert one's rights in a timely manner can result in a claim being barred by laches. Sometimes courts will also require that the party invoking the doctrine has changed its position as a result of the delay, but that requirement is more typical of the related (but more stringent) defense and equally cause of action of estoppel.Template:Citation needed

Components

Template:One source A claim of laches requires the following components:<ref>Template:Cite web</ref>Template:Citation needed<ref name="danjaq">Template:Cite web</ref>

1. a delay in bringing the action,<ref>Template:Cite web</ref>
2. a delay that is unreasonable and
3. that prejudices the defendant.

Delay

The period of delay begins when the plaintiff knew, or reasonably ought to have known, that the cause of action existed; the period of delay ends only when the legal action is formally filed.<ref>Template:Cite web</ref> Informing or warning the defendant of the cause of action (for example by sending a cease-and-desist letter or merely threatening a lawsuit) does not, by itself, end the period of delay.<ref name="danjaq"/>

Unreasonableness

In order to invoke laches, the delay by the opposing party in initiating the lawsuit must be unreasonable. The courts have recognized the following causes of delay as reasonable:Template:Citation needed

• the exhaustion of remedies through the administrative process
• the evaluation and preparation of a complicated claim
• to determine whether the scope of proposed infringement will justify the cost of litigation<ref name="danjaq"/>

By contrast, it is not reasonable to delay a lawsuit to "capitalize on the value of the infringer's labor". In Danjaq v. Sony, the Ninth Circuit decided that a screenwriter who waited for a film studio to publicize and distribute a film based on a script he allegedly owned had delayed his lawsuit unreasonably.<ref name="danjaq"/>

Prejudice

Unreasonable delay must prejudice the defendant. Examples of such prejudice include:Template:Citation needed

• evidence favorable to the defendant becoming lost or degraded
• witnesses favorable to the defendant dying or losing their memories
• the defendant making economic decisions (e.g. investing in a movie or a manufacturing process) that it would not have done, had the lawsuit been filed earlier.<ref name="danjaq"/>

Unreasonable delay may also prejudice the rights of third-parties who were unknown in the case earlier but whose rights got created in the intervening period of the delay (e.g.: the defendant inducts new persons on a disputed property by sale, or by lease).

Procedure

Template:Primary sources section A defense lawyer raising the defense of laches against a motion for injunctive relief (a form of equitable relief) might argue that the plaintiff comes "waltzing in at the eleventh hour" when it is now too late to grant the relief sought, at least not without causing great harm that the plaintiff could have avoided. In certain types of cases (for example, cases involving time-sensitive matters, such as elections), a delay of even a few days is likely to be met with a defense of laches, even where the applicable statute of limitations might allow the type of action to be commenced within a much longer time period. In courts in the United States, laches has often been applied even where a statute of limitations exists, although there is a division of authority on this point.<ref name="Little Bit of Laches" />

If a court does accept the laches defense, it can decide either to deny the request for equitable relief or to narrow the equitable relief that it would otherwise give. Even if the court denies equitable relief to a plaintiff because of laches, the plaintiff may still have a claim for legal relief if the statute of limitations has not run out.

Under the United States Federal Rules of Civil Procedure, laches is an affirmative defense, which means that the burden of asserting laches is on the party responding to the claim to which it applies.

The laches defense does not apply if the claimant was a minor during the time that the claim was not brought, so a party can bring a claim against an historical injustice when they reach their majority.<ref name=MajorityDefense>Template:Cite web</ref>Template:Primary source inline

Compared to statute of limitations

The defense of laches resembles a statute of limitations since both are concerned with ensuring that plaintiffs bring their claims in a timely fashion.

However, a statute of limitations is concerned only with the time that has passed. Laches is concerned with the reasonableness of the delay in a particular situation and so is more case-specific and more focused on the equitable conduct of the plaintiff. Those considerations are not unique to the laches defense because they are characteristic of equitable reasoning and equitable remedies,<ref name="Little Bit of Laches" /> whereas limitation is a statutory remedy.

In the US, the proper disposal of claims in light of those two areas of law has required attention through to the Supreme Court. In Petrella v. Metro-Goldwyn-Mayer (2014), the US Supreme Court rebuffed a defendant's claim that laches barred a copyright infringement suit because Congress had established a detailed statutory scheme, including a statute of limitations.<ref name=Fisher>Template:Cite journal</ref> <ref>Template:Cite web</ref>Template:Primary source inline

Examples

Template:Expand section Template:Primary sources In the Virginia Republican primary for the 2012 US presidential election, several candidates did not appear on the ballot because they failed to obtain sufficient petition signatures. Four of the unsuccessful candidates—Rick Perry, Jon Huntsman, Newt Gingrich, and Rick Santorum—sued, claiming that restrictions on the persons allowed to gather signatures were unconstitutional.<ref>Template:Cite book</ref> Their claim was dismissed by the district court on the grounds of laches, because, in the words of the appellate court: Template:Blockquote The appeals court upheld the dismissal on grounds of laches, but it added that the challenge would likely have succeeded if it had been brought in a timely fashion.<ref name="perry"/>

In Grand Haven, Michigan, the Northwest Ottawa Community Health System sued Grand Haven Township and Health Pointe, which was in the process of building a competing medical facility in the township, arguing that the township ignored its own zoning ordinance in approving the project. On March 24, 2017, as part of a ruling dismissing the lawsuit, Circuit Court Judge Jon A. Van Allsburg noted that the Northwest Ottawa Community Health System waited more than eight months from the date the project was approved before filing the lawsuit and that during that time, plaintiff Health Pointe had purchased construction materials.<ref>Template:Cite news</ref>

The defense of laches is often used as an affirmative defense in patent infringement lawsuits in the USA. In 2021, the Court of Appeals for the Federal Circuit allowed the USPTO to use laches as a reason for denying patents to an applicant, who filed hundreds of applications, that were "atypically long and complex", and who filed amendments, which increased the total number of claims to roughly 115,000. This applicant alone forced the USPTO to create an art unit of twelve experienced examiners solely to examine its patents.<ref>Hyatt v. Hirshfeld, 998 F.3d 1347, 1369 (Fed. Cir. 2021). </ref><ref>Template:Cite web</ref>
