What this brief does and why the defendant files it

A defendant's brief in support of summary judgment is a written argument that the defendant (the property owner or manager being sued) is asking the court to dismiss the case before trial. The defendant is saying: "Even if everything the plaintiff claims is true, the law does not require me to pay damages." It is not a denial of facts—it is an argument that those facts, taken as given, do not add up to legal liability.

The defendant files this brief after the plaintiff has presented their evidence during discovery (the exchange of documents and witness statements). At that point, both sides have seen what the other has. The defendant uses the brief to tell the judge that no reasonable jury could find the defendant liable based on what has been disclosed. If the judge agrees, the case ends without a trial.

This is a critical moment in the case. If the judge denies the motion, the case moves toward trial. If the judge grants it, the plaintiff loses without ever presenting evidence to a jury. Understanding what the brief argues—and what it does not argue—helps you see how strong the defendant's legal position actually is.

Key Takeaways

  • The brief argues that the defendant owed no duty to the plaintiff, the defendant did not breach any duty, or the plaintiff cannot prove causation—not that the injury did not happen.
  • The defendant must show that no reasonable jury could find liability, which is a high bar; the judge does not decide who is right, only whether a jury could reasonably disagree.
  • The brief cites case law from your state showing when property owners are and are not responsible for injuries on their property.
  • If the judge grants summary judgment, the case ends and the plaintiff cannot appeal to a jury; if denied, the case proceeds to trial.
  • Your lawyer can file a response brief arguing why the case should go to a jury, and may request oral argument before the judge rules.

The three legal arguments the brief typically makes

A defendant's summary judgment brief in a premises liability case usually rests on one or more of three legal foundations. The first is no duty: the defendant argues that the law did not require them to protect the plaintiff from the specific hazard that caused the injury. For example, a property owner might argue they had no duty to warn about a natural condition on the land (like a slope or tree root) because the law in that state does not impose such a duty on owners of undeveloped property.

The second is no breach: the defendant admits a duty existed but argues they did not violate it. They might show that they inspected the property regularly, that the hazard was not visible during a reasonable inspection, or that they posted warnings that the plaintiff ignored. A store owner might argue they mopped the floor within the last hour, so a spill could not have been there long enough for them to discover it.

The third is no causation: the defendant argues that even if they breached a duty, the breach did not cause the plaintiff's injury. This is less common in summary judgment but appears when the plaintiff's own conduct clearly caused the harm—for instance, the plaintiff was looking at their phone and did not see a hazard that was plainly visible, or the plaintiff ignored a clear warning sign.

The brief will cite cases from your state's courts showing how courts have ruled in similar situations. These cases establish what the law actually requires of property owners in your jurisdiction.

What evidence the defendant presents in the brief

The brief does not introduce new evidence; it organizes and interprets evidence already exchanged during discovery. The defendant will reference deposition testimony (recorded statements from witnesses, including the plaintiff), photographs, inspection records, maintenance logs, security camera footage, and informed reports. The brief quotes these materials to show that the facts do not support liability.

For example, if the plaintiff slipped on a wet floor, the defendant might cite the store manager's deposition saying the floor was mopped at 2 p.m. and the incident occurred at 2:15 p.m., plus a photograph showing no visible spill. The brief argues this evidence shows the defendant could not have known about the hazard and therefore did not breach a duty to warn or clean.

The defendant's lawyer will also present informed testimony if relevant—a security informed might testify that the property's lighting met industry standards, or a medical informed might testify that the plaintiff's injury was consistent with a fall from a different cause than the one alleged. The brief uses these informed opinions to undermine the plaintiff's theory of what happened.

How the judge evaluates the motion

The judge does not decide whether the defendant is right or wrong. Instead, the judge asks: "Could a reasonable jury, looking at all this evidence, find that the defendant is liable?" If the answer is yes, the motion is denied and the case goes to trial. If the answer is no—if no reasonable jury could possibly find liability based on the evidence—the judge grants the motion and dismisses the case.

This is a high bar for the defendant to clear. The judge must view all evidence in the light most favorable to the plaintiff and resolve all reasonable doubts in the plaintiff's favor. The defendant must show that the evidence is so one-sided that only one conclusion is possible. A close case, or one where reasonable people could disagree, will go to a jury.

The judge will also consider whether the plaintiff has presented enough evidence to meet their burden of proof. In a premises liability case, the plaintiff must show that the defendant owed a duty, breached it, and caused injury. If the plaintiff has presented no evidence on even one of these elements, the defendant wins on summary judgment.

Your response brief and what happens next

After the defendant files their brief, you (through your lawyer) have the opportunity to file a response brief arguing why the case should go to a jury. This brief points out evidence that supports your version of events, disputes the defendant's interpretation of the law, or shows that reasonable jurors could disagree about the facts. You might argue that the defendant's own evidence—say, a maintenance log showing no inspection for three days—proves they did not check the property often enough.

You can also request oral argument, a hearing where your lawyer and the defendant's lawyer speak directly to the judge about the motion. Oral argument gives you a chance to respond to the defendant's arguments in real time and answer the judge's questions. Not all judges allow it, and not all cases warrant it, but it can be valuable when the legal issues are complex or the facts are genuinely disputed.

After the response brief and any oral argument, the judge issues a ruling. This ruling is usually written and explains the judge's reasoning. If the motion is denied, discovery continues and the case moves toward trial. If granted, you can appeal the decision to a higher court, though appeals in summary judgment cases are difficult to win because the judge's decision is reviewed for abuse of discretion, not de novo.

Red flags in the defendant's brief that suggest weakness

A strong summary judgment brief will cite multiple cases from your state showing that similar defendants were not liable. If the brief relies mainly on cases from other states or federal courts, or if the cases cited are distinguishable from yours (different facts, different legal standards), that is a sign the defendant's legal position may be weaker than it appears. Your lawyer should flag these distinctions in the response brief.

Another red flag is selective presentation of evidence. If the defendant's brief quotes only the parts of a deposition that help them and omits testimony that hurts them, your response brief can point this out. Judges notice when one side cherry-picks evidence. Similarly, if the defendant relies on an informed opinion that is contradicted by your informed, or if their informed lacks relevant credentials, that undermines their argument.

Watch also for arguments about the law that seem to contradict how your state's courts have actually ruled. If the defendant argues that property owners have no duty to inspect for hazards, but your state's courts have said they do, the brief is built on a false premise. Your response brief should highlight this directly.

What happens if summary judgment is granted or denied

If the judge grants the motion, the case is over. The defendant wins without a trial. You lose the opportunity to present evidence to a jury. You can appeal, but appeals are slow and expensive, and the standard for overturning a summary judgment ruling is strict. The judge must have made a clear legal error or overlooked evidence that a reasonable jury could rely on. Many appeals of summary judgment are denied.

If the judge denies the motion, the case proceeds to trial. Both sides will present evidence, witnesses will testify, and a jury will decide whether the defendant is liable. Denying summary judgment does not mean you will win at trial—it only means the judge believes a jury could reasonably find you liable. The defendant still has a chance to convince the jury they are not responsible.

Between the denial of summary judgment and trial, settlement negotiations often intensify. Both sides now know the case will go before a jury, which introduces uncertainty. The defendant may be more willing to settle because they face the risk of a jury verdict. Your lawyer can use the judge's denial of summary judgment as leverage in these negotiations.

Frequently Asked Questions

Does the defendant have to prove I am lying about what happened?

No. The defendant does not have to prove your account is false. They only have to show that even if everything you say is true, the law does not hold them liable. This is why summary judgment is so powerful—the defendant can win without ever saying you are wrong about the facts.

Can I introduce new evidence after the defendant files their brief?

Not usually. Summary judgment happens after discovery is closed, meaning both sides have already exchanged evidence. If you have evidence you did not disclose during discovery, you may be able to file a supplemental declaration or ask the judge for permission to reopen discovery, but this is difficult and requires a good reason. Work with your lawyer early to make sure all relevant evidence is gathered before summary judgment motions are filed.

What if the defendant's brief cites a case I have never heard of?

Your lawyer will research it. Cases cited in a summary judgment brief are usually from your state's appellate courts and establish the law on premises liability. Your lawyer will read the full case, not just the excerpt the defendant quoted, and will explain in the response brief whether the case actually supports the defendant's argument or whether it can be distinguished from your situation.

If summary judgment is denied, does that mean I will win at trial?

No. A denial of summary judgment only means the judge believes a jury could reasonably find you liable. The defendant still has a full opportunity to present their case at trial and convince the jury they are not responsible. Many cases survive summary judgment and are then lost at trial.

How long does it take for the judge to rule on the summary judgment motion?

This varies widely by court and judge. Some judges rule within weeks; others take months. Your lawyer can ask the judge's clerk for an estimate. While you are waiting, continue preparing for trial in case the motion is denied, because you may not have much time between the ruling and trial.
