Can You Get a Court to Stop a Data Center? What an Injunction Actually Requires

Start with the vocabulary, because the vocabulary is where most residents go wrong. Kansas law states the concept in a single sentence that is as clear as any in American law: "Injunction is an order to do or refrain from doing a particular act. It may be the final judgment in an action, and it may also be allowed as a provisional remedy." That is K.S.A. 60-901, and every word of it matters. An injunction is an order. It is a judgment or a provisional remedy. It is something that happens inside a case.

So there is no such thing as filing an injunction. A resident who wants a data center stopped has to have a legal claim first: that the rezoning was adopted without the notice the statute required, that an agency issued a permit it had no authority to issue, that the facility is a private nuisance, that turbines are running without a permit the Clean Air Act requires. The lawsuit is built on the claim. The injunction is what you ask the court to do about it. If the underlying claim fails, the request for an injunction fails with it, no matter how bad the project is.

There are three kinds, and they do different jobs on different clocks.

• Temporary restraining order. The emergency device. Federal Rule of Civil Procedure 65(b) allows a court to issue one without notice to the other side only if a sworn affidavit or verified complaint clearly shows that "immediate and irreparable injury, loss, or damage will result" before the other side can be heard, and only if the movant's attorney certifies in writing what efforts were made to give notice and why notice should not be required. It is deliberately short. Rule 65(b)(2) says the order expires at the time the court sets after entry, "not to exceed 14 days," unless the court extends it for a like period for good cause or the adverse party consents to a longer extension. A TRO buys days.
• Preliminary injunction. The order that holds through the litigation. Rule 65(a)(1) is blunt about the difference: "The court may issue a preliminary injunction only on notice to the adverse party." That means a hearing, with the operator's lawyers present and opposing you, usually on an evidentiary record built in a matter of weeks. This is the order that actually stops construction while a case is decided, and it is the one this guide is mostly about.
• Permanent injunction. The relief entered after you win, as part of the final judgment. The Supreme Court's test for it, from eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006), requires a plaintiff to demonstrate "that it has suffered an irreparable injury," "that remedies available at law are inadequate to compensate for that injury," "that considering the balance of hardships between the plaintiff and defendant, a remedy in equity is warranted," and "that the public interest would not be disserved by a permanent injunction." A permanent injunction usually arrives years after the concrete was poured, which is why it is more often an order to fix something than an order to stop something.

Rule 65(d) governs what any of these orders has to look like. It must state the reasons it issued, state its terms specifically, and "describe in reasonable detail" the acts restrained or required, "not by referring to the complaint or other document." And it binds only people who receive actual notice of it: the parties, their officers and agents, and persons in active concert or participation with them. A court order against one developer does not automatically reach a contractor nobody named.

In federal court the controlling statement of the standard comes from Winter v. Natural Resources Defense Council, 555 U.S. 7 (2008), a case in which environmental groups sought to restrict the Navy's use of sonar in training exercises. The Court wrote: "A plaintiff seeking a preliminary injunction must establish that he is likely to succeed on the merits, that he is likely to suffer irreparable harm in the absence of preliminary relief, that the balance of equities tips in his favor, and that an injunction is in the public interest."

Read that as four separate burdens, all carried by you, all at once, early, before discovery has produced much of anything.

• Likelihood of success on the merits. Not a chance of success. Likely success. At a stage where the operator has produced no documents and no witness has been deposed, you are asking a judge to make a preliminary prediction that you will win. This is why a defect that appears on the face of the public record, a notice that was not published the required number of times, a permit that was never issued, is worth more at this stage than the strongest expert opinion that has not been developed yet.
• Likely irreparable harm. The Winter Court specifically rejected the more forgiving rule the Ninth Circuit had used. "The 'possibility' standard is too lenient," the Court said. "This Court's frequently reiterated standard requires plaintiffs seeking preliminary relief to demonstrate that irreparable injury is likely in the absence of an injunction." The next section is entirely about this factor, because it is where these requests usually die.
• Balance of equities. The Court instructed that judges "must balance the competing claims of injury and must consider the effect on each party of the granting or withholding of the requested relief." On one side of that balance is your household. On the other is a construction schedule, financing commitments, equipment orders, and a workforce.
• The public interest. Courts should "pay particular regard for the public consequences in employing the extraordinary remedy of injunction." This factor cuts in more than one direction in data center cases. Clean air, drinking water, and the integrity of a public hearing process are public interests. So, an operator will argue, are grid reliability, tax base, and jobs.

Two framing points from Winter are worth memorizing before any consultation. First, "a preliminary injunction is an extraordinary remedy never awarded as of right." Second, the four factors are what a federal court applies. State courts apply their own tests, which resemble the federal one in most places and differ in details that matter, and some states codify pieces of it by statute. Which test governs your case depends on which court your case belongs in, and that is a question for a lawyer licensed where you live.

The word irreparable is doing precise legal work. It does not mean serious, or unfair, or life changing. It means a court cannot repair it later with a check.

The Supreme Court has said this about as plainly as it can be said. In Sampson v. Murray, 415 U.S. 61 (1974), the Court quoted with approval the rule that "the key word in this consideration is irreparable. Mere injuries, however substantial, in terms of money, time and energy necessarily expended in the absence of a stay, are not enough. The possibility that adequate compensatory or other corrective relief will be available at a later date, in the ordinary course of litigation, weighs heavily against a claim of irreparable harm."

Now apply that to the harms residents actually describe. A home worth less because a substation and eighteen buildings went up across the road is a loss an appraiser can quantify, which makes it look like a damages case, not an injunction case. Nights of lost sleep from cooling fans are real and are compensable in a nuisance suit, which again points toward money. Construction dust and cracked drywall are repair costs. None of that means those claims are weak. It means those claims point toward damages, and an operator's first argument against an injunction will be exactly that: whatever these neighbors have lost, this court can pay them for it at the end of the case, so there is no need to stop a billion dollar project now.

Courts have treated some harms as irreparable, and the pattern is instructive. In Amoco Production Co. v. Village of Gambell, 480 U.S. 531 (1987), the Court observed that "environmental injury, by its nature, can seldom be adequately remedied by money damages and is often permanent or at least of long duration, i.e., irreparable." That sentence is the doorway most community cases try to walk through: an aquifer drawn down, a wetland filled, a spring destroyed, a stream loaded with sediment, a stand of old growth cleared, a battlefield or a burial ground graded flat. The common thread is that the resource is unique and its destruction cannot be undone by writing a check.

Two cautions about that doorway, both from Amoco itself. The Court in that same case said "the bases for injunctive relief are irreparable injury and inadequacy of legal remedies," and it rejected the idea that irreparable harm should be presumed from an agency's failure to evaluate environmental impacts, calling that presumption "contrary to traditional equitable principles." Environmental framing helps. It is not a shortcut. You still have to prove that the specific harm to the specific resource is likely, and likely before the case can be decided on the merits.

This is the honest bottom line, and it is the reason to read the rest of this page carefully rather than hopefully: irreparable harm is the factor on which resident requests to halt data centers most often fail, and nothing on this page can tell you how a judge would rule on yours. We do not predict outcomes and no one else should either.

Here is the provision that ends more conversations in a lawyer's office than any of the four factors, and that virtually no one outside the practicing bar has heard of.

Federal Rule of Civil Procedure 65(c) reads: "The court may issue a preliminary injunction or a temporary restraining order only if the movant gives security in an amount that the court considers proper to pay the costs and damages sustained by any party found to have been wrongfully enjoined or restrained. The United States, its officers, and its agencies are not required to give security."

Read what that sentence actually does. If you persuade a judge to stop a project and it later turns out the order should not have been entered, you can be made to pay what stopping it cost. The security is posted up front, before the order takes effect. It exists to protect the party you enjoined, not you. And the exemption written into the rule is for the United States, not for homeowners.

Now put that next to the scale of the projects. The data center campuses being fought in court are not ordinary developments. The suit challenging the Joliet, Illinois approval concerns a 795 acre project reported at $20 billion. The Bessemer, Alabama rezoning fight concerned a campus of more than four million square feet reported at $1.49 billion. A court setting security under Rule 65(c) is not asked to price your household's inconvenience. It is asked to price what a halt costs the enjoined party: idle crews and equipment, carrying costs on financing, delayed delivery of contracted capacity, penalties under construction and supply agreements. On a project of that size, a delay measured in months is not a rounding error, and a bond calibrated to it can be an amount an ordinary family, or a neighborhood association passing a hat, simply cannot post. The request is not denied. It becomes unavailable.

The honest qualifier is that courts have real discretion here, and how much varies enormously by jurisdiction. Even the federal rule fixes the amount only at what "the court considers proper," which is a grant of judgment, not a formula. State practice ranges widely across the three statutes we were able to quote:

• Kansas makes the undertaking the default and adds a detail worth noticing. K.S.A. 60-905(b) provides that "no temporary injunction shall operate unless the party obtaining the same shall give an undertaking with one or more sufficient sureties in an amount fixed and approved by the judge of the court, securing to the party injured the damages such injured party may sustain including attorney fees if it be finally determined that the injunction should not have been granted." Attorney fees are inside the Kansas undertaking. The statute exempts the state and its agencies, and then adds: "For any other party, at the discretion of the judge, the undertaking required by this subsection may be waived."
• Virginia uses language close to the federal rule: no temporary injunction takes effect "until the movant gives bond with security in an amount that the trial court considers proper to pay the costs and damages sustained by any party found to have been incorrectly enjoined." Va. Code 8.01-631 exempts the Commonwealth and its officers and agencies, and also excepts fiduciaries and persons for whom the court deems a bond "improper or unnecessary."
• Illinois flips the default entirely. Under 735 ILCS 5/11-103, "the court in its discretion, may before entering a restraining order or a preliminary injunction, require the applicant to give bond," and no bond is required of a governmental office or agency. In Illinois the security is permissive on its face.

So the accurate statement is not that a bond will bankrupt you, and it is not that judges routinely waive it. It is that the security requirement is a live, case dispositive issue that has to be raised in the first conversation with counsel, that its size is set by a judge exercising discretion against the backdrop of what the defendant stands to lose, and that in some states the judge may waive it altogether. What the answer is in your court, on your facts, is exactly the kind of question only a lawyer admitted there can answer.

Injunction practice runs on a paradox that catches communities every time. The relief is reserved for emergencies, and the way a court decides whether something is an emergency is largely by looking at how fast you moved.

Think about it from the bench. A resident says construction must be halted immediately because the harm cannot be undone. The operator's lawyer stands up and points out that the approval was granted five months ago, the site work has been visible from the road since spring, and the plaintiffs did nothing until the trucks reached their fence line. The delay itself becomes the answer to the motion. If the harm were truly imminent and irreparable, the argument goes, these plaintiffs would not have waited. Rule 65(b) makes the same point structurally: an order without notice requires a sworn showing of injury that will occur "before the adverse party can be heard in opposition." That is a claim about the calendar.

Delay carries a second, separate danger with a name. Laches is, as Cornell's legal encyclopedia puts it, "a doctrine in equity whereby courts can deny relief to a claimant with an otherwise valid claim when the party bringing the claim unreasonably delayed asserting the claim to the detriment of the opposing party." Mere passage of time is not enough; the delay has to be unreasonable and it has to have hurt the other side. But on a construction project, prejudice from delay accumulates automatically. Every week you wait, the defendant pours more money into the ground, which strengthens both its balance of equities argument and its laches defense. Waiting makes the other side's case for it.

Then there are the hard deadlines running in parallel, which are not equitable at all and do not care how good your reasons are. The statutory window to challenge a local zoning decision can be as short as 10 days and is commonly 30, measured from a trigger event that may be the vote, the written decision, the filing of the decision in the board's office, or publication of the ordinance, depending on the state. Damage claims run on statutes of limitations measured in years, commonly in the two to six year range depending on state and claim type. A federal citizen suit under the Clean Air Act cannot be commenced, under 42 U.S.C. 7604(b), "prior to 60 days after the plaintiff has given notice of the violation" to the EPA Administrator, to the state where the violation occurs, and to the alleged violator, which means that federal environmental route to an injunction opens with a two month wait. Our deadlines guide covers those clocks, and the appeal deadline guide has the zoning windows statute by statute.

The practical consequence is that the day of the approval vote, not the day the bulldozers appear, is when a community that wants to preserve this option needs to be talking to a lawyer.

A preliminary injunction record gets built in weeks, sometimes days. Lawyers who take these cases are not turning down good claims because the claims are bad. They are turning them down because there is no time to assemble a record from scratch. Everything below is material you can gather yourself, before you retain anyone, and having it in one place is the single biggest thing you can do to make the first meeting productive.

• The approval documents. The application and every amendment to it, the staff report, the ordinance or resolution as adopted, the conditions and proffers, the site plan, the development agreement, and any host community agreement. Get the version that was actually voted on, and note the date it was released to the public.
• The notice record. The publication affidavits from the newspaper, the mailing list for adjoining owners, the posted sign photographs, and the text of the advertisement itself. Procedural defects are the claims that have actually won in this area, and they live here.
• The meeting record, and whether anyone objected on it. Minutes, agendas, video, and any written comments submitted before the vote. This matters twice over: some states require that a challenger objected at the administrative level to have standing later, and a reviewing court in most states is working from the record the board made. An objection that is not in the record is often not available to argue.
• Consultant studies the county posted. Acoustic models, traffic studies, stormwater and hydrology reports, water supply analyses, and any environmental review. Check whether the same study exists in more than one version; the differences between them are frequently the most useful thing in the file.
• Photographs and baseline measurements. Dated photographs of the site and of your property before construction, sound readings taken before the equipment is running, and video of existing conditions. Baseline is the word that matters. A measurement taken after the harm starts proves a level. A pair of measurements proves a change.
• Well tests and water records. A certified laboratory test of your well before construction, static water level if you can get it, and your utility's records. This is the one item that becomes impossible to recreate once ground is broken.
• The names of everyone affected. A list of neighbors, their distance from the site, and what each one is experiencing or expects to experience. Who is harmed, and how their harm differs from the general public's, is a threshold legal question, not a detail.

Our evidence guide covers the measurement side in detail, and our guide to finding a lawyer for a data center case covers who handles which kind of fight and how the fees usually work.

It is also worth being clear about what emergency relief buys when it is granted, because the most instructive American example is a win. In Bessemer, Alabama, homeowners challenging the Project Marvel rezoning obtained a temporary restraining order that stopped the city council from acting. It worked. It also expired, and once it did the council proceeded and gave the project final approval in November 2025; the case was later dismissed on a joint stipulation in June 2026. Our case page has the history. A TRO stops the clock. It does not stop the project. What a TRO is for is preserving the situation long enough for a court to hold a real hearing on a preliminary injunction, and that hearing is the one that decides anything.

Everything in the previous section is work a resident can do without retaining anyone, and it costs almost nothing. That is the honest payoff of understanding this area: filing is not a do it yourself project, but the record that filing depends on very much is.

Five things preserve options rather than spend them:

• Submit public records requests. Every state has a records act. A written request to the county or city for the application file, the notice affidavits, staff correspondence with the developer, and any consultant studies costs a stamp and often produces material no reporter has looked at. Counties post far more than most residents realize, and what they have not posted you can ask for.
• Preserve objections on the record. Before any vote, submit written objections identifying every defect you can see: the notice, the missing exhibits, the agreement released too late to read, the study that was never done. Read them into the record at the hearing and ask that the letter be attached to the minutes. This is the single cheapest action with the largest effect on what remains legally available afterward.
• Document conditions before construction. Dated photographs, sound readings, a certified well test, video from your property line. Baseline evidence has a deadline that no statute sets and no judge can extend: the day the work starts.
• Gather neighbors. Build the list of affected households, with distances and specifics. Groups retain counsel that individuals cannot afford, group funded retainers are common in rezoning challenges, and the number of affected households changes how every part of a case is evaluated.
• Attend every meeting. Planning commission, board of supervisors or county commission, city council, and any utility or water district proceeding. Amendments and conditions change between meetings, and the version that was voted on is frequently not the version that was advertised.

Now the part that deserves straight talk rather than a lecture. Nobody can stop you from representing yourself. Federal law says so directly: under 28 U.S.C. 1654, "in all courts of the United States the parties may plead and conduct their own cases personally or by counsel." The choice is genuinely yours. What is worth knowing before you make it is what the choice involves in this particular kind of proceeding.

A preliminary injunction motion against a represented corporate defendant is close to the hardest thing in civil litigation for a non lawyer. The standard is demanding and it is front loaded: you carry four burdens simultaneously, on a compressed schedule, before discovery has given you much of anything. The evidence is formal. Facts reach a judge through admissible affidavits, verified pleadings, and testimony that survives cross examination, not through what everyone in the neighborhood knows to be true. The opposing side is a firm that does this constantly, and it will contest standing, the adequacy of the record, the scope of the requested order under Rule 65(d), the amount of security under Rule 65(c), and every factual assertion you make.

Two consequences are worth weighing specifically. First, procedural missteps in this area can be irreversible in a way that ordinary mistakes are not: an appeal deadline that runs while a motion is pending is gone, and an objection that never made it into the administrative record often cannot be added later. Second, a denied request is not a neutral event. A judge's findings on likelihood of success and irreparable harm are made on the record you put in front of the court, and they can shape how the rest of the case is litigated and evaluated. A weak first attempt is not free.

None of that is a reason to do nothing. It is a reason to spend your unrepresented effort on records, objections, baseline measurements, and organizing, all of which make a case stronger and none of which can be procedurally botched, and to have the filing conversation with a lawyer admitted in your state.
