A Tactical Win: Partial Summary Judgment on Liability

In the high-stakes world of civil litigation, victory often comes down to efficiency and leverage. While many defendants view a motion for Summary Judgment (SJ) as a case-killer—an attempt to dispose of the entire claim—litigants sometimes overlook the strategic goldmine that is Partial Summary Judgment (PSJ) on Liability. This maneuver, typically governed by Rule 56 of the Federal Rules of Civil Procedure, offers a powerful way to secure a pre-trial “win” and fundamentally reshape the remainder of the case.

A partial grant of judgment is not merely a procedural step; it is a tactical earthquake. By having the court determine that a party is liable as a matter of law, you eliminate the single largest risk factor for any trial—the question of fault—and transform the subsequent proceedings into a highly focused inquest on damages alone.

The Foundation: Understanding Partial Summary Judgment on Liability

Summary Judgment (Rule 56) is granted when the movant demonstrates that there is no genuine dispute as to any material fact and they are entitled to judgment as a matter of law. PSJ applies this standard to a subset of the case. Specifically, Rule 56(a) allows a party to move for summary judgment on “the part of each claim or defense” on which judgment is sought. When liability is the target, this means:

 
1. The court finds the defendant breached a duty or committed the tort/breach (the liability element).

   

2. The court reserves the determination of the plaintiff’s injury amount (the damages element) for trial.

The Strategic Upside: Why PSJ on Liability is a Game Changer

Securing a partial victory on liability offers significant strategic benefits that extend far beyond courtroom procedural advantages:

Cautions and Best Practices for a Successful Motion

Filing a strong motion for PSJ requires careful planning and execution. The judiciary can be skeptical of partial motions, particularly in jurisdictions concerned about increasing overall litigation costs and the risk of inconsistent findings by multiple judges on related issues.

   
       
           
           
       
   
   
       
           
           
       
       
           
           
       
       
           
           
       
   

Best Practice Area	Key Action for the Legal Expert
Evidentiary Focus	Rely almost exclusively on adverse party admissions, official documents, or undisputed contractual terms. Avoid reliance on the moving party’s own oral testimony, which can often be challenged as not satisfying the “no genuine dispute” standard.
Issue Separation	Select a claim or element that is perfectly discrete. Contract breach or liability based on a clear statutory violation (negligence per se) are often ideal targets.
Procedural Clarity	Ensure the motion clearly states it is for liability only, reserving all issues of causation, mitigation, and damages for the jury. Use your motion to help the court define the precise issues remaining for trial.

Summary: Securing Your Litigation Advantage

Partial Summary Judgment on the issue of liability is one of the most effective strategic tools in the Civil Cases litigation toolkit. When the facts are favorable and undisputed, a successful motion delivers an undeniable advantage that profoundly impacts the case trajectory and settlement negotiations.

 
1. PSJ fundamentally changes the nature of the trial from a complex fault determination to a focused damages assessment.

   

2. It places immediate, high-pressure leverage on the opposing party, often leading to a more favorable and earlier settlement outcome.

   

3. The motion forces the non-movant to show their hand and clarify the disputed facts early, improving the movant’s Litigation Strategy.

   

4. By narrowing the issues for trial, it reduces the overall time and cost associated with a lengthy jury presentation on liability.

Frequently Asked Questions (FAQ)

 

Q: What is the primary legal basis for PSJ on Liability?

   

A: The basis is Rule 56(a) of the Federal Rules of Civil Procedure (FRCP), which permits a party to seek judgment on “part” of a claim, provided there is no genuine dispute of material fact regarding the liability element.

   

Q: Does a grant of PSJ on liability end the case?

   

A: No. While it resolves the issue of fault, the case continues to trial solely for the determination of the amount of Damages (the injury and monetary relief).

   

Q: Can a defendant file for Partial Summary Judgment?

   

A: Yes. Defendants often file for PSJ to eliminate specific claims, theories of liability (like negligent entrustment once vicarious liability is admitted), or entire categories of damages (like future lost earnings) where the plaintiff lacks evidence.

   

Q: Why do courts sometimes discourage PSJ motions?

   

A: In some jurisdictions, judges worry that “slicing” a case into pieces through PSJ can increase complexity, lead to inconsistent findings (if multiple judges touch the case), and ultimately create more delay and cost than a single, unified trial.
