Digital Data Is the New Battleground in Civil Litigation
Text messages. Emails. Cloud storage. Deleted files. Metadata buried inside documents you forgot you created. In modern civil litigation, electronically stored information has become one of the most aggressively pursued categories of evidence, and for good reason. Digital data can reveal patterns, communications, timelines, and details that paper records simply cannot match.
What many people do not realize is that a subpoena demanding your electronically stored information is not a blank check. California law places real boundaries on what can be demanded, how it must be produced, and under what circumstances a court can step in to limit or block production entirely.
If you are on the receiving end of one of these subpoenas, understanding those boundaries is not just useful. It could be the difference between protecting your privacy and handing over far more than you were ever legally required to give.
What a Subpoena for Electronically Stored Information Can Actually Demand
A subpoena in a California civil proceeding can require that electronically stored information be produced and that the requesting party or someone acting on their behalf be permitted to inspect, copy, test, or sample that information. The reach of that language is significant. It is not limited to documents sitting neatly in a folder. It extends to data in any format, stored on any system, that falls within the scope of the request.
The party issuing the subpoena is permitted to specify the form or forms in which they want the information produced. They might ask for native file formats, PDFs, searchable text, or some other technical specification. This matters because the format in which data is produced can affect how easily it is searched, analyzed, and used against you in the proceeding.
However, if no format is specified in the subpoena, the person responding is required to produce the information either in the form in which it is ordinarily maintained or in a form that is reasonably usable.
Crucially, you are never required to produce the same electronically stored information in more than one form. That is a protection worth knowing because overzealous opposing counsel sometimes pushes for multiple formats of the same data, and you have the legal right to push back on that demand.
You Can Object to the Format of Production
If the subpoena specifies a particular format and you have legitimate grounds to object to it, California law allows you to state your objection and identify the form or forms in which you intend to produce the information instead. This is not an automatic excuse to ignore the subpoena, but it is a recognized right that gives you a measure of control over how your data is presented.
This kind of objection requires precise legal language and a clear understanding of what formats are technically available and defensible in your specific situation. An experienced defense attorney who understands both litigation procedure and the technical realities of electronic data management can make a real difference here. Poorly drafted objections get overruled. Well crafted ones can shape the entire scope of what gets produced.

The "Not Reasonably Accessible" Defense Is a Powerful Tool
One of the most significant protections California law provides to someone subpoenaed for electronically stored information is the ability to argue that the data being sought comes from a source that is not reasonably accessible because of undue burden or expense. This is not a get out of jail free card, but it is a serious legal argument that courts take genuinely seriously.
If you raise this argument, the burden falls on you to demonstrate that the source is not reasonably accessible. That means you need evidence. Technical documentation, expert testimony, cost estimates, and a clear explanation of why retrieving the data would impose a disproportionate burden are all tools your attorney can marshal to support this position.
Even if the court finds that the data is not reasonably accessible, the subpoenaing party can still ask the court to order production by showing good cause. But here is where it gets important from a defense perspective: the court has the authority to set conditions on that discovery, including requiring the requesting party to bear the expense of retrieval.
Shifting the cost of expensive and burdensome data recovery onto the party demanding it is a meaningful protection, and one that often causes opposing parties to narrow or abandon overbroad requests once they realize they will have to pay for what they are chasing.
Courts Have the Power to Limit Electronic Discovery
Even when electronically stored information is reasonably accessible, California law gives courts clear authority to limit the frequency or extent of discovery if certain conditions are present. This is one of the most defense friendly aspects of the entire statutory framework, and it deserves more attention than it typically receives.
A court must limit electronic discovery if the information can be obtained from another source that is more convenient, less burdensome, or less expensive. It must also step in if the discovery being sought is unreasonably cumulative or duplicative, meaning the requesting party is essentially asking for the same information over and over through different demands. If the requesting party has already had ample opportunity through other discovery in the case to obtain what they are asking for, that is another basis for the court to limit or deny the subpoena.
Perhaps the most practically significant limitation is the proportionality analysis courts are required to conduct. When the likely burden or expense of producing the electronically stored information outweighs the likely benefit, taking into account the amount in controversy, the resources of the parties, the importance of the issues, and the relevance of the requested discovery to resolving those issues, the court can and should rein in the request.
This framework gives a skilled defense attorney substantial ammunition to fight back against sweeping digital subpoenas that are really just fishing expeditions dressed up in legal language.
Privilege Still Protects Your Data
If you produce electronically stored information pursuant to a subpoena and later realize that some of what you produced was subject to a claim of privilege or attorney work product protection, California law gives you a process to address that. You notify the subpoenaing party of the claim, and the protections governing privileged materials kick in from that point forward.
This is a two sided protection. It means that if privileged communications or work product were inadvertently swept up in a broad production, there is a legal mechanism to claw that information back rather than treating the disclosure as a permanent waiver. It also underscores why having legal counsel review what is being produced before production happens is so important. Catching privileged material before it goes out the door is always better than trying to retrieve it afterward.
The Obligation to Avoid Undue Burden Goes Both Ways
The party serving a subpoena for electronically stored information is not simply entitled to demand whatever they want and leave the responding party to figure out how to comply. California law expressly requires the subpoenaing party to take reasonable steps to avoid imposing undue burden or expense on the person responding. Courts enforcing these subpoenas are similarly required to protect people who are not parties to the litigation from suffering disproportionate consequences simply because their data happens to be relevant to someone else's dispute.
When the subpoenaing party ignores these obligations and serves a subpoena that is overbroad, technically unreasonable, or financially oppressive, that is not just bad practice. It is a violation of legal duties that a defense attorney can bring directly to the attention of the court.
Sanctions for Lost Data Are Limited Under the Right Circumstances
One final protection that often goes overlooked: if electronically stored information is lost, damaged, altered, or overwritten as a result of the routine and good faith operation of an electronic information system, courts are generally prohibited from imposing sanctions on the subpoenaed person or their attorney for that loss. Automatic deletion schedules, routine system updates, and standard data management practices that result in the loss of potentially relevant data are not treated as intentional misconduct absent exceptional circumstances.
This does not mean you can deliberately destroy evidence and hide behind routine operations as a shield. The law makes clear that existing obligations to preserve discoverable information remain in full force. But for data that is genuinely lost through ordinary system operation before any preservation duty attached, this protection matters.
If you are facing a subpoena for electronically stored information and are unsure what you are required to produce, how to object, or how to protect privileged material, talking to a defense attorney before you respond is the right call.
