Civil Investigative Demand Response

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

If the Department of Justice has served you with a civil investigative demand, the most useful thing anyone can tell you is what its arrival usually means: a False Claims Act case has probably already been filed against you, under seal, and you cannot see it. A CID is issued under 31 U.S.C. § 3733 during a false claims investigation, and qui tam complaints are filed “in camera” and “shall remain under seal for at least 60 days” under 31 U.S.C. § 3730(b)(2). The seal is routinely extended. So the CID is frequently the first outward sign of a lawsuit that has been pending, invisibly, for months or years.

The second thing worth knowing immediately: a CID is not a subpoena and not civil discovery. It is a pre-suit compulsory instrument that reaches documents, written interrogatories and oral testimony — all three, in one instrument. No other pre-suit tool in federal practice combines them.

What this page answers at a glance

Question	Short answer	Authority
What is a CID?	A pre-suit written demand from the Attorney General or a designee in a false claims investigation.	31 U.S.C. § 3733(a)(1)
What can it compel?	Documents, written interrogatories, and oral testimony — or “any combination.”	§ 3733(a)(1)(A)–(D)
Does it mean I am being sued?	Usually there is a sealed qui tam complaint. A CID issues before the government decides whether to intervene.	§ 3733(a)(1); § 3730(b)(2)
Am I a target?	Not necessarily. CIDs go to third parties who are not accused of anything.	§ 3733(a)(1)
Must it tell me the theory?	Yes. It “shall state the nature of the conduct constituting the alleged violation … and the applicable provision of law alleged to be violated.”	§ 3733(a)(2)(A)
How soon can testimony be taken?	Not less than seven days after the demand is received, absent exceptional circumstances.	§ 3733(a)(2)(F)
How do I challenge it?	A petition to modify or set aside, filed within 20 days of service or before the return date, whichever is earlier.	§ 3733(j)(2)(A)
Can the material end up in a criminal case?	The custodian may deliver it to a DOJ attorney “designated to appear before any court, grand jury, or Federal agency.”	§ 3733(i)(3)

The sealed qui tam: why the CID is a signal, not just a document

Start with the statutory sequence, because it is what makes the inference reliable.

Section 3733(a)(1) authorizes the Attorney General or a designee to issue a CID “before commencing a civil proceeding under section 3730(a) or other false claims law, or making an election under section 3730(b).” Section 3730(b) is the qui tam provision — the election it refers to is the government’s decision whether to intervene in a case a private relator has already filed.

So the statute contemplates two situations in which a CID issues: before the government files its own case, and before the government decides what to do about a case someone else has already filed.

Now read § 3730(b)(2):

“The complaint shall be filed in camera, shall remain under seal for at least 60 days, and shall not be served on the defendant until the court so orders.”

And § 3730(b)(3): “The Government may, for good cause shown, move the court for extensions of the time during which the complaint remains under seal,” and “[a]ny such motions may be supported by affidavits or other submissions in camera.”

Put the provisions together and the position is stark. A relator — usually a current or former employee, a competitor, or a billing contractor — files a complaint in your name that you are not served with and cannot read. The government investigates while the case sits sealed, moving for extensions supported by filings you never see. Sixty days is the statutory floor, not the norm; seals running for years are ordinary. The defendant “shall not be required to respond to any complaint filed under this section until 20 days after the complaint is unsealed and served,” which is the statute’s own acknowledgment that until then you are litigating in the dark.

A CID is therefore not merely a request for information. It is very often the only externally visible event in a case that already exists. Treating it as a routine document request — assigning it to a compliance officer, producing quickly to appear cooperative, and moving on — is the most common and most costly error at this stage.

That does not mean a sealed case certainly exists. The government also issues CIDs to build its own case from scratch, and to third parties who have information about someone else. But the inference is strong enough that the first question counsel asks is not “what do they want” but “whose case is this, and who is the relator likely to be.”

Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: The CID itself usually tells you more about the relator than the government intends. Section 3733(a)(2)(A) requires the demand to state the conduct alleged and the provision of law. The custodian list and the date ranges narrow it further: a demand focused on one service line, one facility, or one two-year window is describing what somebody with access to that slice of the business told the government. Reading a CID as a description of the informant’s vantage point is the most useful thing you can do with it in the first week.

What a CID is — and the three things it can compel

Section 3733(a)(1) authorizes a demand requiring the recipient:

“(A) to produce such documentary material for inspection and copying, (B) to answer in writing written interrogatories with respect to such documentary material or information, (C) to give oral testimony concerning such documentary material or information, or (D) to furnish any combination of such material, answers, or testimony.”

The combination is what makes the instrument unusual, and it is worth being concrete about the comparison.

Instrument	Documents	Interrogatories	Sworn oral testimony	Requires a filed case?
Civil investigative demand (§ 3733)	Yes	Yes	Yes	No
Grand jury subpoena	Yes	No	Testimony before the grand jury, but no interrogatories	No, but it is a criminal process
Administrative subpoena	Yes	Generally no	Sometimes	No
Civil discovery (Fed. R. Civ. P. 26–36)	Yes	Yes	Yes	Yes — after a complaint is served

Table: why a CID is a category of its own. It is the only pre-suit instrument that reaches documents, written interrogatories and sworn oral testimony together.

Written interrogatories are the underrated component. A deposition can be met with “I don’t recall.” An interrogatory is answered in writing, after investigation, by the entity — and it locks the entity into a position on contested questions before anyone has seen the government’s evidence. Answers are prepared under time pressure, by people who often do not yet know what the case is about, and they are very difficult to retract later.

“Documentary material” is broader than paper. Section 3733(l)(5) defines it to include “the original or any copy of any book, record, report, memorandum, paper, communication, tabulation, chart, or other document, or data compilations stored in or accessible through computer or other information retrieval systems, together with instructions and all other materials necessary to use or interpret such” material. In a health care matter that reaches the practice management system, the electronic health record, claims data, and the instructions needed to make sense of them.

Who issues a CID, and who receives one

Who issues. The Attorney General “or a designee (for purposes of this section),” and the statute adds expressly: “The Attorney General may delegate the authority to issue civil investigative demands under this subsection.” In practice CIDs are signed within the Civil Division or by a United States Attorney’s office under delegated authority.

Who receives. “[A]ny person” the Attorney General has “reason to believe … may be in possession, custody, or control of any documentary material or information relevant to a false claims law investigation.” Section 3733(l)(4) defines “person” broadly: “any natural person, partnership, corporation, association, or other legal entity, including any State or political subdivision of a State.”

Note what that standard does not require. It does not require reason to believe the recipient violated anything. It requires reason to believe the recipient has relevant information. Third parties who are not accused of anything routinely receive CIDs — billing companies, laboratories, referral sources, former employers, vendors, and physicians whose only connection is that they signed orders.

This matters in two directions. If you are a third party, a CID is not an accusation and should not be treated as one. And if you are the subject, the fact that CIDs have gone to your billing vendor and your former practice manager is information: it tells you where the government thinks the documents are.

Reading the CID: what it is required to tell you

A CID is a disclosure document as well as a demand, and the required contents are the reader’s best window into the investigation.

The theory. Section 3733(a)(2)(A): “Each civil investigative demand issued under paragraph (1) shall state the nature of the conduct constituting the alleged violation of a false claims law which is under investigation, and the applicable provision of law alleged to be violated.”

That sentence is doing real work. It obliges the government to name the conduct and the statutory provision — which means the CID tells you whether the theory is presentment, false record, reverse false claim, or a kickback-tainted claim, before you produce anything. A demand whose statement of conduct is so general as to be uninformative is itself a point to raise with the government, and it is a common opening in scope negotiation.

For documents, § 3733(a)(2)(B) requires the demand to “describe each class of documentary material to be produced with such definiteness and certainty as to permit such material to be fairly identified”; to “prescribe a return date for each such class which will provide a reasonable period of time within which the material so demanded may be assembled and made available”; and to identify the investigator.

The “reasonable period” language is the textual basis for extension requests. If the return date does not allow a reasonable period to assemble what has been demanded — and for enterprise data it frequently does not — that is not a favor being asked. It is what the statute requires.

For interrogatories, § 3733(a)(2)(C) requires the demand to “set forth with specificity the written interrogatories to be answered” and prescribe dates for the answers.

For oral testimony, § 3733(a)(2)(D) requires the demand to prescribe date, time and place; identify the investigator conducting the examination and the custodian receiving the transcript; “specify that such attendance and testimony are necessary to the conduct of the investigation”; “notify the person receiving the demand of the right to be accompanied by an attorney and any other representative”; and “describe the general purpose for which the demand is being issued and the general nature of the testimony, including the primary areas of” inquiry.

That last requirement is a genuine advantage and is routinely underused. The government must describe the primary areas of inquiry in advance. Preparation is therefore possible in a way it is not for a grand jury appearance.

Timing. Section 3733(a)(2)(F): “The date prescribed for the commencement of oral testimony pursuant to a civil investigative demand issued under this section shall be a date which is not less than seven days after the date on which demand is received, unless the Attorney General or an Assistant Attorney General designated by the Attorney General determines that exceptional circumstances are present which warrant the commencement of such testimony within a lesser period of time.”

Seven days is a floor, not a norm. Testimony dates are commonly negotiated further out, and the seven-day provision is best read as telling you how little time the statute guarantees — not how much you should accept.

Oral testimony: the component that makes a CID dangerous

The testimony provision is where CID practice diverges most sharply from ordinary civil discovery, and where the risk to individuals is concentrated.

Where it happens and who is there. Under § 3733(h)(1) the examination is “taken before an officer authorized to administer oaths and affirmations,” the witness is placed on oath, and the testimony “shall be taken stenographically and shall be transcribed.” Under § 3733(h)(2) the investigator “shall exclude from the place where the examination is held all persons except the person giving the testimony, the attorney for and any other representative of the person giving the testimony, the attorney for the Government, any person who may be agreed upon by the attorney for the Government and the person giving the testimony, the officer before whom the testimony is to be taken, and any stenographer taking such testimony.”

Read that list carefully. It is closed. There is no right for the company’s counsel to attend an individual employee’s examination unless that lawyer represents the witness or the parties agree. An employee who assumes company counsel will be sitting beside them may find they are not.

Objections are sharply limited. Section 3733(h)(7)(A) is the provision to know verbatim:

“Any person compelled to appear for oral testimony under a civil investigative demand issued under subsection (a) may be accompanied, represented, and advised by counsel. Counsel may advise such person, in confidence, with respect to any question asked of such person. Such person or counsel may object on the record to any question, in whole or in part, and shall briefly state for the record the reason for the objection. An objection may be made, received, and entered upon the record when it is claimed that such person is entitled to refuse to answer the question on the grounds of any constitutional or other legal right or privilege, including the privilege against self-incrimination. Such person may not otherwise object to or refuse to answer any question, and may not directly or through counsel otherwise interrupt the oral examination.”

Three consequences follow.

1. Counsel may attend and may advise in confidence — this is not a grand jury, where counsel waits in the corridor.
2. Objections are available only to assert a right or privilege, and must be stated briefly on the record. There is no relevance objection, no form objection, no speaking objection. “Such person may not otherwise object to or refuse to answer any question.”
3. The privilege against self-incrimination is expressly preserved — and this is where an individual custodian’s position becomes acute.

The Fifth Amendment problem for an individual

A company cannot assert the privilege against self-incrimination; it is personal. So when a CID demands oral testimony from a named individual — a practice manager, a billing supervisor, a physician — that person faces a decision the entity cannot make for them.

Answering under oath creates a transcript. Section 3733(i)(3) provides that where a DOJ attorney “has been designated to appear before any court, grand jury, or Federal agency in any case or proceeding, the custodian … may deliver to such attorney such material, answers, or transcripts for official use in connection with any such case or proceeding as such attorney determines to be required.” The statute contemplates the transcript traveling into a grand jury room. This is a civil instrument whose product is not confined to the civil case.

Asserting the privilege, on the other hand, is visible to the government, permits an adverse inference in the civil case, and may put the individual at odds with an employer whose interests point towards full cooperation.

There is no general answer to that problem, and this page will not pretend to one. What can be said is structural: the decision belongs to the individual, not to the company, and an individual whose own conduct is in the frame needs their own lawyer before the examination rather than after it. That divergence — company counsel and employee interests pulling apart — is the subject of our Upjohn warning page, and the same dynamic arises in regulatory investigations generally, as our SEC defense lawyer page describes.

Building the response

Preservation is immediate and non-negotiable

The obligation to preserve attaches on receipt, and in practice earlier — an organization that reasonably anticipates litigation is already on notice. That means auto-deletion off, backup rotation suspended, departing-employee mailboxes held, text messages on personal devices used for work captured, and the hold documented in writing.

The reason for the urgency is not only evidentiary. Destroying or altering records after learning of a federal investigation is a separate federal offense. 18 U.S.C. § 1519 reaches anyone who “knowingly alters, destroys, mutilates, conceals, covers up, falsifies, or makes a false entry in any record, document, or tangible object with the intent to impede, obstruct, or influence the investigation or proper administration of any matter within the jurisdiction of any department or agency of the United States … or in relation to or contemplation of any such matter,” and carries up to 20 years. It does not require that a proceeding be pending — “in relation to or contemplation of” is enough.

A defensible billing dispute becomes an indefensible obstruction case with remarkable speed. We do not develop the obstruction analysis here; the point is that the preservation step comes before the strategy discussion, not after it.

Negotiating scope and custodians

Almost every CID is negotiated. The statute supports it in three places: the “reasonable period” requirement for return dates in § 3733(a)(2)(B)(ii); the definiteness requirement in § 3733(a)(2)(B)(i); and § 3733(j)(2)(A)(ii), which contemplates “such longer period as may be prescribed in writing by any false claims law investigator identified in the demand.”

Productive negotiations usually run on custodians, date ranges, search terms and data formats rather than on refusal in principle. The practical goals: reduce a demand for “all documents” to identified custodians; align the date range with the conduct actually described under § 3733(a)(2)(A); agree formats for structured claims data so that production does not become a second dispute; and get any extension confirmed in writing, because the statute’s petition deadline turns on dates.

Privilege

Section 3733(b)(1) is the protective provision:

“A civil investigative demand issued under subsection (a) may not require the production of any documentary material, the submission of any answers to written interrogatories, or the giving of any oral testimony if such material, answers, or testimony would be protected from disclosure under— (A) the standards applicable to subpoenas or subpoenas duces tecum issued by a court of the United States to aid in a grand jury investigation; or (B) the standards applicable to discovery requests under the Federal Rules of Civil Procedure, to the extent that the application of such standards to any such demand is appropriate and consistent with the provisions and purposes of this section.”

Two standards, imported by reference. Attorney-client privilege and work product are therefore available, and are asserted by log rather than by silent withholding.

The recurring hard problem is the internal investigation file. If the organization has already investigated the conduct with counsel, that file is exactly what the government wants and exactly what privilege was meant to protect — and a decision to produce it, or to waive in order to obtain cooperation credit, has consequences for every individual who spoke to the investigators.

---

The petition to modify or set aside — and its very short deadline

This is the most commonly missed deadline in CID practice, and it is not generous.

Where. Section 3733(j)(2)(A): the recipient “may file, in the district court of the United States for the judicial district within which such person resides, is found, or transacts business, and serve upon the false claims law investigator identified in such demand a petition for an order of the court to modify or set aside such demand.” For a demand aimed at a product of discovery, the petition “may be brought only in the district court of the United States for the judicial district in which the proceeding in which such discovery was obtained is or was last pending.”

When. Any such petition must be filed:

“(i) within 20 days after the date of service of the civil investigative demand, or at any time before the return date specified in the demand, whichever date is earlier, or (ii) within such longer period as may be prescribed in writing by any false claims law investigator identified in the demand.”

Read the disjunction carefully, because it runs the wrong way from most litigation deadlines. Whichever is earlier. If the return date is fifteen days out, the window is fifteen days, not twenty. A short return date shortens the challenge period rather than extending it.

Clause (ii) is the practical answer in most matters: a written extension from the investigator, which is one of the reasons every extension should be confirmed in writing rather than by telephone.

Petitions are not filed lightly. They are public where the investigation is not, they consume goodwill that is usually worth more in negotiation, and courts give the government considerable latitude at the investigative stage. But the deadline runs whether or not anyone is thinking about it, and a client who discovers a fundamental defect on day 25 has fewer options than one who diarised the date on day one.

Where the material goes afterwards

Recipients often assume that material produced under a civil instrument stays in the civil case. The statute does not say that.

Under § 3733(i)(2)(A), the custodian “shall take physical possession of such material, answers, or transcripts and shall be responsible for the use made of them.” Under § 3733(i)(2)(B), the custodian “may cause the preparation of such copies … as may be required for official use by any false claims law investigator, or other officer or employee of the Department of Justice.”

And under § 3733(i)(3), headed “Use of material, answers, or transcripts in other proceedings”:

“Whenever any attorney of the Department of Justice has been designated to appear before any court, grand jury, or Federal agency in any case or proceeding, the custodian of any documentary material, answers to interrogatories, or transcripts of oral testimony received under this section may deliver to such attorney such material, answers, or transcripts for official use in connection with any such case or proceeding as such attorney determines to be required.”

The statute expressly contemplates delivery to an attorney appearing before a grand jury. That is not a prediction that a criminal case will follow — most CIDs do not produce one — but it disposes of the assumption that a civil production is walled off from criminal exposure. Where a parallel criminal investigation is a realistic possibility, that assessment belongs at the front of the response, and it is why a federal criminal defense attorney practice, rather than civil counsel alone, is usually involved in a CID response in the health care space.

What a CID does not mean

A short section, because the anxiety is real and much of it is misplaced.

• It is not a charge. No offense has been alleged against anyone. It is an investigative instrument.
• It is not a finding. The government has “reason to believe” the recipient has relevant information. That is the whole standard.
• It does not mean you are the target. Third parties receive CIDs routinely.
• It does not mean the government will intervene. The election under § 3730(b)(4) — proceed or decline — has not been made when a CID issues; that is precisely why the CID was issued.
• It does not mean a criminal case is coming. Most false claims investigations resolve civilly or are closed.

What it does mean is that a process with real deadlines has begun, and that decisions made in the first fortnight — about preservation, about scope, about who represents whom — shape everything afterwards. We will not tell any reader what their exposure is. That assessment requires the file.

---

The first two weeks

1. Diary four dates from the CID itself: the document return date, any interrogatory dates, any testimony date, and the § 3733(j) petition deadline — 20 days from service or the return date, whichever is earlier.
2. Issue a written litigation hold and suspend auto-deletion, before anything else.
3. Read § 3733(a)(2)(A) statement of conduct closely. It names the theory and the provision. That is the case, in the government’s own words.
4. Map the custodians and date ranges against the described conduct, and identify where the demand reaches beyond it.
5. Work out who needs separate counsel, before anyone is interviewed internally or examined under oath.
6. Contact the investigator early about scope and schedule, and confirm every agreement in writing.
7. Assume a sealed complaint exists and think about who is in a position to have filed it.
8. Do not produce quickly to look cooperative. Speed is not credit, and an unconsidered production or interrogatory answer is very hard to walk back.

Where this leads next depends on the theory. If the conduct described involves referral or compensation arrangements, the analysis is on our Stark Law attorney page. If it involves billing, coding or medical necessity, see our Medicare fraud attorney page. If exclusion is a realistic consequence of any resolution, that administrative track is on our OIG exclusion page. Where funds or property may be restrained, see asset forfeiture. And where the same facts could support criminal counts, the framework is on our white collar crime lawyer hub, with the specific offenses on our wire fraud lawyer, money laundering attorney, embezzlement lawyer, bank fraud attorney, tax fraud lawyer, securities fraud lawyer, insider trading lawyer, investment fraud attorney and FBAR penalties pages. Sentencing exposure, if a case ever reaches that stage, is covered in our federal sentencing pages; review of a completed case runs through federal appeals and, for claims outside the record, a § 2255 motion.
