The Injunction Hearing
The preliminary injunction is one of several ways to protect a plaintiff before trial. At law, courts give provisional relief through attachment, garnishment, and replevin, and a plaintiff can sometimes secure its position ex parte with no judicial process at all, as by filing a lis pendens notice or a notice of a mechanics' lien.1 The injunction restrains the defendant's conduct, and Rule 65(a)(1) lets a court issue it only after the defendant has been told: “The court may issue a preliminary injunction only on notice to the adverse party.”2
Notice is only the first step, and the rule's text stops there. The courts have supplied the rest by reading Rule 65(a) to require a hearing, and this section follows that hearing through three questions: what it requires, what kind of evidence it may rest on, and whether the court may merge it with the trial itself. The showing the movant must make at the hearing belongs to the next section. One feature of that showing is worth previewing: the Second, Seventh, and Ninth Circuits allow relief on only a serious question on the merits when the movant also shows grave irreparable harm and a balance of equities that tips heavily in its favor.3
What the Hearing Requires
The text of Rule 65(a)(1) speaks of notice and never uses the word hearing. The hearing requirement is the courts' reading of the rule, and it is a settled one: the circuits have agreed that notice implies a hearing, and Rule 65(a) is universally interpreted to require one before a preliminary injunction issues.4
The reading follows from what notice is worth. Notice tells a defendant that an application is pending, and its only value lies in the chance it gives the defendant to answer. A court that announced the motion and then ruled on the plaintiff's papers alone would have handed the defendant a warning with no forum in which to act on it, and the judge would have heard only one side's account of the facts. The hearing is the event that notice exists to make possible, which is why courts read the two requirements as a pair.
A hearing is not a trial. By definition it is something less than a full trial on the merits, and how much testimony to admit is a matter for the sound discretion of the trial judge.5 That latitude fits the stage of the case. A court deciding a preliminary injunction need not make binding findings of fact; it must find probabilities that the necessary facts can be proved,6 and a proceeding with that purpose has no need to run as long as a trial.
The judge's discretion over how much evidence to take does not reach the question of who gets to offer it. In Sims v. Greene, the district court, after the first round of appeal, held a hearing at which only the plaintiff received a significant chance to present evidence. The Third Circuit reversed, because a hearing implies a fair opportunity for both sides to present testimony.7 Nothing in that holding faulted the hearing for being short. The defect was that the opportunity was lopsided, which turned the defendant's notice into an empty formality. The First Circuit states the same test in substantive terms: given the nature and circumstances of the case, did the parties have a fair opportunity to present relevant facts and arguments to the court and to counter the opponent's submissions? If the question is close and time permits, doubt is resolved in favor of taking evidence.8
Two tempting answers are both wrong. The first reasons from the text: the rule says only notice, so no hearing is required. That answer ignores the courts' uniform reading of Rule 65(a). The second reasons from the trial: a short, paper-heavy proceeding cannot be a hearing. That answer ignores the fact that a hearing is something less than a trial. The question that sorts the cases is whether each side had a fair chance to present evidence and argument.
Affidavits Versus Live Evidence
A hearing does not always mean witnesses on a stand. Rule 65(a)(1) conditions a preliminary injunction on notice to the adverse party, and the courts read that condition to require a hearing,10 but neither the rule nor that reading says whether the hearing must be oral. The First Circuit gave a functional answer in Aoude v. Mobil Oil Corp.: in certain settings a matter can adequately be “heard” on the papers.11 The test is substantive. Given the nature and circumstances of the case, did the parties have a fair opportunity to present relevant facts and arguments to the court and to counter the opponent's submissions?12
The test looks to opportunity because the hearing exists to give notice its value, and live testimony is only one way to deliver that value. A rule demanding witnesses in every case would turn a provisional proceeding into a trial. A rule accepting any paper filing would let a plaintiff's untested account support an order against the defendant. The functional test sits between the two. It asks what the record already contains and whether anything that live testimony could add is genuinely in dispute.
The record in Aoude shows a paper hearing that worked. The litigation had been pending for some months. When the judge ruled on the cross-motions for injunctions, the file held detailed briefs, affidavits from six of the principal witnesses, hundreds of pages of deposition testimony, and more than two dozen documentary exhibits. The parties had also had extensive discovery, and the critical facts about what had happened earlier were not genuinely in dispute.13 Live witnesses would have added little to a record of that depth, so the court found a fair opportunity and no reversible error. The court also set a limit on its own holding: if the question is close and time permits, doubt should be resolved in favor of taking evidence.14 A paper hearing is therefore an exception that a full record earns. It is not a shortcut available whenever the docket is crowded.
What does a paper hearing look like when it fails?
The contractor's position draws on two rules. The first comes from Atari Games Corp. v. Nintendo of Am., Inc., where the Federal Circuit, applying Ninth Circuit law, restated that a preliminary injunction generally should not issue on affidavits alone and that a district court should be wary of granting one based solely on allegations and conclusory affidavits submitted by the plaintiff.15 The court pointed to Ninth Circuit antitrust decisions that reversed an injunction resting on conclusory affidavits and denied another supported by only two affidavits.16 The mechanism is easy to trace. An affidavit is one party's account, prepared for the litigation and untested by cross-examination. A conclusory affidavit gives the judge the party's conclusion, such as that the defendant is causing harm, without the underlying facts the judge needs to decide whether the conclusion is true. When the other side disputes those facts, the judge cannot choose between two sworn versions.
The second rule protects the request itself. Fengler v. Numismatic Americana, Inc., 832 F.2d 745 (2d Cir. 1987), is the usual citation for the point that if the party to be restrained requests a hearing, refusing it is an abuse of discretion.17
The two lines do not conflict, because both apply the fair-opportunity test to different records. Aoude involved a file built through discovery, with sworn testimony, exhibits, and undisputed critical facts, so nothing that a live hearing would add was missing. Atari warns about thin, one-sided submissions on disputed facts, where the paper cannot show which account is true. A request for a hearing adds weight to the second side of the scale. It tells the court that the party to be restrained does not regard the paper record as fair, and Aoude does not stretch to cover a refusal when the critical facts are genuinely contested. In a close case with time to spare, the court should take evidence.
Because the hearing exists to give the defendant an answer to the plaintiff's showing, the parties may give it up. They may waive a hearing and submit the motion on affidavits, but it must be clear that they have waived and are willing to proceed only by affidavits.18 The demand for clarity follows from what is surrendered, since the waiver replaces the one protection that notice was meant to secure. A court will not infer consent from silence or from a vague remark about the paperwork. A defendant who signs a stipulation to submit the motion on the filed affidavits has waived. One whose lawyer says only that the papers look fine has not.
Two opposite errors recur. The first treats “hearing” as meaning live witnesses and condemns any decision on documents, which ignores Aoude. The second treats the permission to use affidavits as a license to decide every motion on paper, which ignores Atari and the rule that a party who asks for a hearing generally gets one. To decide whether a paper hearing will do, ask four questions:
- How full is the record, and are the critical facts genuinely disputed?
- Do the affidavits state facts, or only conclusions?
- Has anyone requested a hearing, or clearly waived one?
- Does time permit the court to take evidence?
Consolidation With Trial
Rule 65(a)(2) lets a court enlarge the preliminary injunction hearing into the trial itself: “Before or after beginning the hearing on a motion for a preliminary injunction, the court may advance the trial on the merits and consolidate it with the hearing.”20 To advance the trial is to move it up from its place on the calendar. To consolidate is to let one proceeding serve as both the preliminary hearing and the trial, so that the court's ruling at the end is a decision on the merits and no longer a prediction about them. The phrase “before or after beginning” matters in practice, because a judge who opens a hearing and sees partway through that the remaining evidence is the evidence the merits would require can consolidate at that point, without having decided in advance.
The option exists for economy. When the evidence on the interim question and on the final question overlaps heavily, two proceedings would have the same witnesses tell the same story twice, and the plaintiff would wait months for an answer the court already has the material to give. Consolidation also changes the character of the court's decision. At the preliminary stage a court need not make binding findings of fact and must find only probabilities that the necessary facts can be proved,21 while a consolidated proceeding ends in a decision on the merits.
The second sentence of Rule 65(a)(2) works whether or not the court consolidates. Evidence that is received on the motion and that would be admissible at trial becomes part of the trial record and need not be repeated at trial.22 Two filters narrow what carries over. The evidence must actually have been received at the hearing, and it must be of a kind that would be admissible at trial. A statement that the judge could consider on the motion but that would be excluded at trial falls outside the carry-over by the rule's own terms. The point of the provision is that witnesses and lawyers need not say again what the court has already heard.
The last sentence of the rule limits both features: the court must preserve any party's right to a jury trial.23 The limit exists because consolidation is a tool of efficiency, and efficiency should not erase an entitlement to a jury on issues that carry one. An injunction is an equitable remedy decided by the judge, but a single lawsuit can pair a request for an injunction with a claim on which a party has demanded a jury. A judge who consolidates must therefore see that any issue carrying a jury right is still tried to a jury.
Had the court instead folded the royalties claim into the consolidated proceeding and decided it from the bench, the consolidation would have run past the limit in the rule's final sentence, because it would have taken away the franchisee's jury. A question that pairs a consolidation order with a pending jury demand tests that proviso, and the answer is never that consolidation is forbidden outright: consolidation may go forward, and the jury right is preserved. A second frequent error is to assume that the record made at an ordinary preliminary hearing disappears unless the court consolidated. The carry-over applies even when consolidation is not ordered, so long as the evidence was received on the motion and would be admissible at trial.
