(a) Any party may obtain discovery within the scope delimited by Chapter 2 (commencing with Section 2017.010), and subject to the restrictions set forth in Chapter 5 (commencing with Section 2019.010), by propounding to any other party to the action written interrogatories to be answered under oath.

(b) An interrogatory may relate to whether another party is making a certain contention, or to the facts, witnesses, and writings on which a contention is based. An interrogatory is not objectionable because an answer to it involves an opinion or contention that relates to fact or the application of law to fact, or would be based on information obtained or legal theories developed in anticipation of litigation or in preparation for trial.

CCP § 2030.010 Summary

California Code of Civil Procedure (CCP) § 2030.010 is the foundational statute that permits parties in a civil lawsuit to send written questions, known as interrogatories, to other parties involved in the same action. These questions are a vital discovery tool designed to gather information and must be answered under oath.

The statute outlines two key aspects:
1. Who can send/receive: Any party to an action can send interrogatories to any other party.
2. Scope of questions: Interrogatories can seek information that falls within the general scope of discovery as defined by other statutes (CCP § 2017.010) and are subject to general discovery restrictions (CCP § 2019.010). Crucially, subsection (b) explicitly allows for “contention interrogatories,” meaning questions that ask whether another party is making a specific claim or argument, and what facts, witnesses, or documents support that claim. It further clarifies that such questions are not objectionable just because they require an opinion, a legal contention, or information gathered in preparation for litigation.

In essence, CCP § 2030.010 establishes the right to use written interrogatories as a discovery method and broadly defines what kinds of questions are permissible, particularly emphasizing the legitimacy of questions about an opposing party’s claims and the evidence supporting them.

Purpose of CCP § 2030.010

The primary purpose of Code of Civil Procedure § 2030.010 is to facilitate a fair and transparent exchange of information between parties involved in California civil litigation. Before this statute and the broader Civil Discovery Act, trials could often be characterized by “ambush” tactics, where parties would intentionally withhold crucial information until the last minute, surprising opponents and hindering justice.

CCP § 2030.010 addresses this problem by formally authorizing the use of interrogatories, thereby promoting:

• Elimination of Surprise: By allowing parties to ask detailed questions about the opposing side’s claims, defenses, and supporting evidence, the statute helps prevent unforeseen revelations at trial.
• Streamlined Litigation: When parties have a clear understanding of the factual and legal bases of each other’s cases, it leads to more efficient case evaluation, promotes realistic settlement negotiations, and narrows down the issues that actually need to be litigated in court.
• Truth-Seeking: Requiring answers under oath encourages honesty and commitment to specific facts and contentions, which is essential for uncovering the truth and achieving a just outcome.
• Codification of Practice: Subsection (b), specifically validating contention interrogatories, clarifies a long-standing area of discovery disputes, ensuring that parties can legitimately inquire into the legal theories and factual underpinnings of an opponent’s case.

Ultimately, CCP § 2030.010 is a cornerstone of California’s discovery process, ensuring that civil cases are decided on their merits rather than on a party’s ability to conceal information.

Real-World Example of CCP § 2030.010

Imagine a personal injury case arising from a rear-end car accident in Los Angeles. Sarah (Plaintiff) claims she suffered whiplash and other injuries when John (Defendant) collided with her car.

Sarah’s attorney, wanting to understand John’s defense, uses CCP § 2030.010 to send a set of written interrogatories to John. These might include questions like:

1. “Do you contend that Plaintiff Sarah was wholly or partially at fault for the accident described in the Complaint? If so, state all facts upon which you base this contention.” (This is a contention interrogatory directly permitted by CCP § 2030.010(b).)
2. “Identify all witnesses, including their names, addresses, and phone numbers, who you contend observed the accident.” (Seeking witnesses supporting a contention.)
3. “Identify all documents, including photographs, videos, or repair estimates, that you contend support your version of how the accident occurred.” (Seeking writings supporting a contention.)
4. “Do you contend that any of Plaintiff’s alleged injuries pre-existed the accident? If so, state all facts upon which you base this contention and identify any medical records or individuals supporting it.” (Another contention interrogatory relating to facts and the application of law to fact, clearly permissible under 2030.010(b).)

John, with the help of his attorney, must provide sworn written answers to these interrogatories within a specific timeframe. These answers will reveal John’s specific defenses, the facts he relies on, and the evidence he intends to use, allowing Sarah’s attorney to better prepare for depositions, mediation, or trial. This exchange of information, facilitated by CCP § 2030.010, is crucial for both sides to understand the strength and weaknesses of their respective cases.

Related Statutes

CCP § 2030.010 does not operate in a vacuum but is part of the broader California Civil Discovery Act. Several other statutes are closely related and commonly referenced alongside it:

• CCP § 2017.010 (Scope of Discovery): This statute is explicitly referenced in CCP § 2030.010(a) and defines the general scope of discovery. It states that parties may obtain discovery regarding any matter, not privileged, that is relevant to the subject matter involved in the pending action or to the determination of any motion made in that action, if the matter either is itself admissible in evidence or appears reasonably calculated to lead to the discovery of admissible evidence.
• CCP § 2019.010 (Methods of Discovery): Also referenced in CCP § 2030.010(a), this statute lists the various methods of discovery available in California civil cases, including oral depositions, written interrogatories, inspections of documents, physical and mental examinations, and requests for admissions. CCP § 2030.010 details the rules specifically for written interrogatories as one of these methods.
• CCP § 2030.020 (Timing of Interrogatories): This statute specifies when a plaintiff or defendant may propound interrogatories, generally allowing plaintiffs to do so 10 days after service of the summons or appearance, and defendants at any time.
• CCP § 2030.030 (Number of Interrogatories): This section sets limits on the number of “specially prepared” interrogatories a party may propound to another (typically 35), and also addresses the use of official form interrogatories, which are not counted against this limit.
• CCP § 2030.210 et seq. (Responses to Interrogatories): This series of statutes details the requirements for responding to interrogatories, including the timeframe for response (usually 30 days), the format of the responses, how to assert objections, and the requirement for answers to be made under oath.

Case Law Interpreting CCP § 2030.010

Code of Civil Procedure § 2030.010 is a foundational statute, and while it is frequently cited in discovery disputes, directly interpretive case law dissecting its specific wording is less common than cases applying its principles or interpreting related sections concerning the scope, limits, or proper responses to interrogatories. The statute’s language, particularly subsection (b) regarding contention interrogatories, largely codifies principles established in earlier case law.

One seminal case that significantly influenced the development of “contention interrogatories,” now explicitly permitted by CCP § 2030.010(b), is:

• City of Long Beach v. Superior Court (1976) 64 Cal.App.3d 60, 71-72: While this case predates the specific numbering of CCP § 2030.010, it established the principle that “contention interrogatories” are generally proper. The court reasoned that it is permissible to require a party to state whether it makes a certain contention, and if so, to state all facts, witnesses, and documents upon which it bases that contention. This ruling laid the groundwork for the clear language now found in subsection (b) of the current statute, solidifying the legitimacy of asking an opposing party to commit to their factual and legal positions. Modern cases often refer back to the principles articulated in *City of Long Beach* when discussing the scope of contention interrogatories.

Later cases, such as Donohue v. Superior Court (2005) 128 Cal.App.4th 201, while not directly interpreting the specific words of 2030.010, frequently affirm the broad scope of discovery under the Civil Discovery Act (including interrogatories) and discuss the balance between discoverable information and privileges (like the attorney work product doctrine), providing context for how 2030.010 operates within the larger discovery framework.

Because CCP § 2030.010 primarily grants the authority to propound interrogatories and defines their basic scope, most case law concerning interrogatories tends to focus on the subsequent statutes that govern the *application* of this discovery tool, such as proper objections, limits on the number of interrogatories, or the adequacy of responses.

Why CCP § 2030.010 Matters in Personal Injury Litigation

In California personal injury litigation, Code of Civil Procedure § 2030.010 is an indispensable tool for both plaintiffs and defendants, significantly shaping litigation strategy and the potential for fair resolution.

For personal injury plaintiffs, this statute is critical for:

• Uncovering Defense Strategies: Plaintiffs can use interrogatories to force defendants to reveal their specific defenses (e.g., comparative fault, pre-existing conditions, lack of causation) and the factual basis for those defenses.
• Identifying Witnesses and Evidence: It allows plaintiffs to discover names of witnesses the defendant intends to call, documents they rely on, and expert opinions relevant to liability or damages. This prevents surprises at trial and aids in thorough deposition preparation.
• Pinning Down Factual Contentions: By requiring defendants to answer under oath, plaintiffs can compel them to commit to specific versions of events, making it harder for them to change their story later.

For personal injury defendants, CCP § 2030.010 is equally vital for:

• Understanding the Plaintiff’s Case: Defendants can ascertain the precise nature of the plaintiff’s injuries, medical treatments, specific economic and non-economic damages claimed, and the factual basis for allegations of negligence.
• Evaluating Damages: Interrogatories help defendants understand how plaintiffs calculate their losses, including lost wages, medical bills, and future care needs, which is crucial for assessing potential liability and settlement value.
• Identifying Liability Theories: Defendants can inquire into the specific acts or omissions the plaintiff alleges constituted negligence and the facts supporting those allegations.

For both plaintiffs and defendants in personal injury cases, CCP § 2030.010 contributes to:

• Informed Settlement Negotiations: With a clearer understanding of the opposing party’s claims, defenses, and supporting evidence, both sides can make more informed decisions about settlement offers, leading to more efficient resolutions.
• Efficient Trial Preparation: Knowing the contours of the opposition’s case well in advance allows attorneys to focus their resources, identify key disputed issues, and prepare more effectively for trial.
• Fairness and Transparency: The ability to demand sworn answers about contentions, facts, witnesses, and documents ensures that personal injury cases are litigated based on a comprehensive understanding of the evidence, fostering a more just outcome for all parties involved, including the clients.
