A motion for judgment on the pleadings and a motion for summary judgment both ask a judge to end a case before trial, but they sit at different points in the lawsuit and rely on different information. The pleadings motion looks only at the complaint and answer. Summary judgment looks at the evidence gathered during discovery. Picking the wrong one wastes time, and worse, attaching evidence to a pleadings motion can accidentally convert it into something else entirely.
The Core Difference at a Glance
Three things separate these motions: when you can file, what the judge is allowed to look at, and what you have to prove.
- A motion for judgment on the pleadings is filed under Federal Rule of Civil Procedure 12(c), after the complaint and answer are both on file but typically before discovery produces much evidence. The court reads only the pleadings and any documents attached to them.
- A motion for summary judgment is filed under Rule 56, usually after discovery, and the court weighs the full evidentiary record: depositions, documents, affidavits, admissions, and interrogatory answers.1Cornell Law School. Federal Rules of Civil Procedure Rule 56 – Summary Judgment
- The pleadings motion asks whether the other side’s written allegations, taken as true, can win as a matter of law. Summary judgment asks whether the evidence shows no genuine dispute over any fact that matters.
If your argument is that the other side’s story, even believed in full, doesn’t add up legally, the pleadings motion fits. If your argument is that the evidence shows the real facts aren’t actually in dispute, summary judgment fits.
Motion for Judgment on the Pleadings
Rule 12(c) lets either party move for judgment once the pleadings are closed, meaning the complaint has been filed and the answer has been served. A defendant might argue that the complaint, read generously, still fails to describe conduct the law punishes. A plaintiff might argue that the defendant’s answer admits enough to end the case right there.
The court accepts all factual allegations in the non-moving party’s pleading as true and views them in the light most favorable to that party.2Cornell Law School. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections If any set of facts consistent with the pleading would support a valid claim or defense, the motion fails. The judge isn’t weighing evidence, because at this stage there isn’t any to weigh.
Rule 12(c) requires the motion to be brought “early enough not to delay trial,” but it sets no specific deadline. Most parties file early, because avoiding discovery costs is the main reason to file at all.
Motion for Summary Judgment
Rule 56 directs that the court “shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.”1Cornell Law School. Federal Rules of Civil Procedure Rule 56 – Summary Judgment A fact is “material” if it could affect the outcome under the governing law. A dispute is “genuine” if the evidence would let a reasonable jury find for the non-moving party.
Parties support their motions by citing specific items from the record: depositions, documents, electronically stored information, affidavits or declarations, stipulations, admissions, and answers to interrogatories. Affidavits and declarations must be based on personal knowledge, contain facts admissible in evidence, and show that the person signing is competent to testify.1Cornell Law School. Federal Rules of Civil Procedure Rule 56 – Summary Judgment
Once the moving party meets its initial burden, the other side can’t survive by pointing back at the allegations in the complaint. They have to come forward with specific evidence showing a genuine dispute. Speculation and vague assertions don’t count.
Timing: a party can file for summary judgment at any point up to 30 days after the close of all discovery, unless the court or a local rule sets a different deadline.1Cornell Law School. Federal Rules of Civil Procedure Rule 56 – Summary Judgment Filing earlier is allowed, but courts sometimes deny a premature motion when the opposing party hasn’t had a fair chance to develop the record.
Partial Summary Judgment
A party can also move for summary judgment on specific claims, defenses, or parts of claims rather than the whole case. Rule 56(a) permits this expressly.1Cornell Law School. Federal Rules of Civil Procedure Rule 56 – Summary Judgment Even when the court doesn’t grant everything requested, it can enter an order declaring certain facts established for the rest of the case, narrowing what a jury has to decide.
The Conversion Trap
Here is where litigants trip up. If either side attaches materials outside the pleadings to a Rule 12(c) motion and the court doesn’t exclude them, the court must treat the motion as one for summary judgment under Rule 56.2Cornell Law School. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections When that happens, all parties must get a reasonable opportunity to present any evidence that’s now relevant.
The rule exists to protect the non-moving party. If the court is going to look at evidence beyond the complaint and answer, the other side deserves a chance to respond with evidence of its own. Stapling exhibits to a 12(c) motion is a common tactical mistake. It pushes the case into summary judgment territory before either side may be ready.
How Both Motions Differ From a Motion to Dismiss
People often confuse a motion for judgment on the pleadings with a motion to dismiss for failure to state a claim under Rule 12(b)(6). The two use the same legal standard: whether, viewing the facts in the light most favorable to the non-moving party, the pleading states a valid claim for relief. The difference is timing.
A Rule 12(b)(6) motion must be filed before the defendant submits an answer.2Cornell Law School. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections A Rule 12(c) motion can only be filed after the pleadings close, meaning the answer is on file. So if a defendant answered the complaint without first moving to dismiss, the 12(b)(6) window has passed, but 12(c) is still available. The outcomes differ too. A granted 12(b)(6) motion typically dismisses the complaint, often with leave to refile an amended version. A granted 12(c) motion produces a judgment that resolves the case.
What Happens After the Court Rules
If the Motion Is Granted
A granted motion for judgment on the pleadings produces a final judgment for the moving party. Courts often give the losing side a chance to fix the problem, because the federal rules direct that leave to amend a pleading should be freely granted when justice requires it. If a complaint fails to state a claim, the plaintiff may get a chance to file an amended version rather than losing outright. That opportunity isn’t unlimited: if the defect can’t be fixed, or the plaintiff has already had several tries, the court can enter judgment without leave to amend.
A granted motion for summary judgment also produces a final judgment on the merits. Because the court has considered the evidence and found no genuine dispute, this judgment carries the same weight as a jury verdict. The losing party generally cannot refile the same claims against the same party in a new lawsuit.
If the Motion Is Denied
Denial of either motion means the case moves forward. A denied 12(c) motion sends the case into discovery. A denied summary judgment motion sends the case toward trial. Neither denial is a final ruling on who wins. It just means the court found enough of a factual or legal question to keep going.
Appeals
A granted motion that resolves the entire case is a final judgment and can be appealed right away. Partial summary judgment is trickier. When a ruling disposes of some claims but not others, it generally isn’t a final, appealable order, and the losing party has to wait until the whole case is over. The one exception: under Rule 54(b), the trial court can certify a partial judgment for immediate appeal if it finds “no just reason for delay.”3Cornell Law School. Federal Rules of Civil Procedure Rule 54 – Judgment and Costs Without that certification, the partial ruling can be revised any time before final judgment.
On appeal, both types of granted motions get fresh review without deference to the trial court’s legal conclusions. For summary judgment, the appellate court reexamines the evidence under the same standard the trial court used and decides independently whether a genuine dispute of material fact exists.
