Protecting Your California Business from Frivolous Lawsuits: The Power of Summary Judgment and the Sham Affidavit Rule

The Power of Summary Judgment in California Business Litigation 

In today's litigious business environment, California business owners face constant threats of lawsuits that can drain resources, damage reputations, and disrupt operations. When your business and legacy are at stake, understanding the legal tools available to efficiently resolve meritless claims becomes essential. One of the most effective tools in your legal arsenal is summary judgment

Summary judgment, also referred to as a "judgment as a matter of law," is a procedural mechanism that allows a judge to resolve a case without a full trial when there is no genuine dispute about the material facts. In California, summary judgment is governed by Code of Civil Procedure § 437c, which provides that a motion "shall be granted if all the papers submitted show that there is no triable issue as to any material fact and that the moving party is entitled to a judgment as a matter of law." 

For Southern California business owners, summary judgment can be a game-changer when facing frivolous lawsuits. Rather than enduring months or years of costly litigation leading to a trial, summary judgment offers an opportunity to resolve cases efficiently when the facts clearly support your position. 

How Summary Judgment Works in California 

When a lawsuit is filed against your business, both parties typically engage in discovery—the formal process of gathering evidence before trial. This includes depositions (recorded testimony), interrogatories (written questions), requests for documents, and requests for admission. 

After discovery, if you believe the evidence shows there are no genuine factual disputes that would require a trial, you can file a motion for summary judgment. This motion essentially asks the court to rule that: 

  1. There are no material facts in dispute that a jury would need to decide 
  2. Based on the undisputed facts, you are entitled to judgment as a matter of law 

As of January 1, 2025, California's summary judgment rules have been updated. The new changes include: 

  • Extended deadlines: Motions must be filed 81 days before the hearing date (plus time for service) 
  • Longer opposition window: Opposition papers are now due 20 days before the hearing (previously 14 days) 
  • Expanded reply timeframe: Reply papers must be filed 11 days before the hearing (previously 5 days) 

These extended timeframes give both parties more opportunity to prepare thorough arguments, which can lead to better judicial decisions. 

The Power of Depositions in Summary Judgment 

Depositions—sworn testimony recorded before trial—play a crucial role in the summary judgment process. When properly conducted, depositions can become powerful evidence that helps secure a favorable ruling. 

In many cases, a party opposing summary judgment may provide the court with an affidavit (a sworn written statement) in an effort to create a factual dispute that would defeat summary judgment. For example, if a plaintiff alleges your company violated a contract and you file for summary judgment with evidence showing full compliance, the plaintiff might submit an affidavit suddenly claiming new facts not previously mentioned. 

This is where the strategic value of early depositions becomes apparent. 

The Sham Affidavit Rule: A Critical Protection for California Businesses 

California courts recognize that allowing parties to contradict their own prior testimony through later affidavits would undermine the efficiency of summary judgment. This led to the development of the "sham affidavit rule," which provides significant protection for businesses facing litigation. 

Under California law, a party's affidavit that contradicts their own prior deposition testimony should be disregarded when considering a motion for summary judgment. The courts recognize that if a party could simply create factual disputes by contradicting their own testimony, it would severely diminish the utility of the summary judgment process in screening out meritless claims. 

The sham affidavit rule is designed to prevent exactly this kind of tactical maneuvering. When a plaintiff gives deposition testimony that undermines their case, they cannot later submit an affidavit contradicting that testimony simply to avoid summary judgment. 

California case law further strengthens this protection through the D'Amico rule, which holds that "a party cannot create an issue of fact by a declaration which contradicts his prior discovery responses." This principle extends beyond deposition testimony to include contradictions of other discovery responses, such as interrogatory answers and responses to requests for admission. 

Exceptions to the Sham Affidavit Rule 

The sham affidavit rule is not absolute. California courts have recognized that there may be legitimate reasons for the discrepancies between deposition testimony and a later affidavit. These exceptions include: 

  1. Confusion during the deposition: If the deponent can show they were confused by unclear questioning during the deposition, a later clarifying affidavit may be considered. 
  2. New information: If the affiant gained access to material facts that were unavailable or unknown at the time of the deposition, an affidavit presenting this new evidence might be accepted. 
  3. Lack of clear contradiction: If the deposition testimony and the affidavit do not clearly conflict, the sham affidavit rule may not apply. 

These exceptions highlight the importance of having a skilled legal team conduct thorough depositions with clear, unambiguous questions that establish the key facts necessary for your case. 

Practical Example: How the Sham Affidavit Rule Works 

Let's consider a practical example relevant to California business owners: 

Imagine your company is sued by a former employee claiming they were not paid for overtime work. During their deposition, the employee admits they never worked more than 40 hours in any week. Later, when you move for summary judgment based on this admission, the employee submits an affidavit claiming they regularly worked 50-hour weeks. 

Under the sham affidavit rule, the court would likely disregard the affidavit since it directly contradicts the employee's prior sworn testimony. Without any other evidence creating a genuine dispute about the hours worked, the court would grant summary judgment in your favor, saving your business the time and expense of a trial. 

Strategic Considerations for Business Owners 

For California business owners, understanding the sham affidavit rule offers several strategic advantages: 

  1. Early deposition strategy: Working with your legal counsel to conduct depositions early in litigation can lock in testimony that might later help secure summary judgment. 
  2. Comprehensive deposition questioning: Ensure that your attorney covers all key elements of the opposing party's claims during depositions, with clear questions that don't leave room for ambiguity. 
  3. Documentary evidence: Supplement deposition testimony with written discovery tools like requests for admission, which can further strengthen your summary judgment position. 
  4. Careful affidavit review: When opposing summary judgment, carefully review your own affidavits to ensure consistency with prior testimony, as contradictions can lead to critical evidence being disregarded.
