DEA Regulatory Defense & Investigations

The Clock Starts the Moment You Are Served.

A DEA registration is not an abstract certificate. It is the operational foundation of your practice or business. When the DEA initiates enforcement, they have already built their record.

You need a lawyer who understands how the DEA works, the right way to respond to an enforcement action, and what can be done to protect your registration, your reputation, and your livelihood. Dhairya Jani is that attorney. He built these cases. Now he defends against them. 

A former DEA Diversion Enforcement Counsel, he has practiced every stage of the process now being used against you: directing investigative strategy, issuing administrative subpoenas, drafting Orders to Show Cause and Immediate Suspension Orders, and trying cases before DEA Administrative Law Judges. That experience is now entirely in your corner.

What Is Actually at Stake

A DEA enforcement action rarely arrives alone. When it begins, the exposure typically extends across multiple fronts simultaneously:

  • DEA Administrative Proceeding: Order to Show Cause (OSC), Administrative Law Judge hearing, DEA Administrator’s Final Order. The timeline is compressed, discovery is limited, and by the time the OSC arrives, the government’s record is already substantially built. A registrant who is not prepared from the moment of first notice is already behind.
  • State Professional Licensing: State medical, pharmacy, osteopathic, and veterinary boards sometimes initiate their own proceedings on the same facts. Positions taken in the DEA administrative matter carry direct consequences in the state forum.
  • Civil Enforcement: 21 U.S.C. § 842(c) authorizes substantial per-violation civil penalties. Civil penalty exposure runs on a separate timeline, and positions taken in the fast-moving administrative proceeding can directly affect the exposure.
  • Criminal Exposure: How a registrant handles a DEA investigation can have consequences for criminal liability. Statements made and strategic decisions during the administrative phase require counsel who understands the intersection with federal criminal practice. Where criminal exposure exists, Jani Law PLLC coordinates with criminal defense counsel to ensure the administrative defense does not create or worsen that exposure.

Jani Law PLLC provides representation that addresses all four fronts simultaneously.

Civil penalty posture, state board coordination, criminal defense coordination where needed, and the strategic sequencing that determines what is possible in each forum are built into the representation from day one.

The Five Grounds for Revocation, Suspension, or Denial

Under 21 U.S.C. § 824(a), a DEA registration may be suspended or revoked on five statutory grounds. Understanding which ground, or combination of grounds, the government is relying on is the first step in building an effective defense:

  1. Material falsification of any application filed pursuant to the Controlled Substances Act.
  2. Conviction of a felony under the Controlled Substances Act or any other federal or state law relating to a controlled substance.
  3. Suspension, revocation, or denial of a state license, leaving the registrant no longer authorized under state law to handle controlled substances.
  4. Acts rendering the registration inconsistent with the public interest under 21 U.S.C. § 823. This is the most commonly litigated ground and the basis for most Orders to Show Cause and Immediate Suspension Orders. 
  5. Exclusion from participation in a federal health care program under 42 U.S.C. § 1320a-7(a).

Ground 4, the “public interest” standard, is the workhorse of DEA enforcement. It governs the majority of actions against prescribers, pharmacies, distributors, and manufacturers. Understanding how the public interest factors apply to your specific situation, your compliance history, and the government’s theory of the case is foundational to the defense.

How DEA Enforcement Actually Works: The Lifecycle

DEA enforcement does not begin with an Order to Show Cause (OSC) or an Immediate Suspension Order (ISO). By the time an OSC or ISO is served, an investigation has typically been underway for months, sometimes for years. Understanding where your matter sits in this lifecycle is where early engagement produces the most value.

Stage 1: Data Analysis and Investigative Targeting

DEA investigations typically begin with data, not field visits. Common triggers include:

  • Controlled substance distribution data
  • State Prescription Drug Monitoring Program (PDMP) pattern analysis
  • Suspicious Orders Reporting System (SORS) data
  • Law enforcement referrals
  • State licensing board coordination
  • Patient complaints
  • Tips from current and former employees

By the time field-level activity begins, the investigative theory is already developed. Most registrants do not know this phase is happening.

Stage 2: Field Investigation 

Field investigation can include:

  • Interviews of patients, employees, former employees, and other healthcare providers
  • Review of licensing and disciplinary records
  • Coordination with state PDMP administrators
  • Coordination with state and local law enforcement 
  • Analysis of dispensing and distribution data

Registrants are often unaware that this phase is occurring.

Stage 3: Administrative Subpoena

An administrative subpoena under 21 U.S.C. § 876 is one of the DEA’s most powerful investigative tools. It is issued without prior judicial approval and with a very low threshold.

Receiving an administrative subpoena is not a routine records request. It is a signal that a formal investigation is active and that the DEA is building its evidentiary record.

Getting the response right requires counsel who understands what the subpoena actually covers and what it does not. Jani Law PLLC analyzes the scope and legal authority of every subpoena and ensures the response is legally sound.

Stage 4: Inspection and Audit

Administrative inspections under 21 U.S.C. § 880 may occur during or following the subpoena phase.

What investigators observe, what they document, and how the registrant and staff respond all become part of the enforcement record.

Jani Law PLLC provides pre-inspection compliance review, representation during inspections, and post-inspection response strategy.

Stage 5: Resolution Short of Formal Proceedings

Not every DEA investigation results in an OSC or ISO. Where the facts support it, matters can resolve through a Letter of Admonition, a negotiated Memorandum of Agreement, or an informal resolution. Each carries different consequences.

  • Letter of Admonition (LOA): No immediate sanction, but it becomes a permanent part of your enforcement history and evidence of prior notice in any future proceeding. Every LOA warrants counsel review and documented corrective action.
  • Memorandum of Agreement (MOA): A regulatory probation with reporting requirements, compliance milestones, operational restrictions, and audits lasting two to five years. Terms that appear manageable on paper can create significant operational burdens. The MOA becomes part of your permanent enforcement history. Do not sign an MOA without experienced counsel reviewing every term.

Stage 6: Order to Show Cause and Immediate Suspension Order

An Order to Show Cause formally initiates proceedings to revoke or suspend your DEA registration, or to deny a pending application. You have exactly 30 days from the date of service to request a hearing before a DEA Administrative Law Judge. Miss that window and all allegations are deemed admitted. The DEA may then act on the OSC without a hearing.

An Immediate Suspension Order under 21 U.S.C. § 824(d) takes effect the moment it is served. Everything stops: prescribing, dispensing, ordering, receiving. Non-compliance creates criminal exposure on top of the administrative proceeding. The ISO can be challenged in federal district court while the OSC proceeding runs concurrently. Both tracks require same-day action.

Have You Received an OSC or ISO? You have exactly 30 days from the date of service to request a hearing. Time is not a variable you can recover. Call Jani Law PLLC immediately.

Stage 7: Administrative Hearing

Administrative hearings before a DEA Administrative Law Judge involve live testimony, direct and cross-examination of fact witnesses including DEA diversion investigators, along with expert witnesses, documentary evidence, and post-hearing briefing. The Administrative Law Judge issues a Recommended Decision and the DEA Administrator issues the Final Order. Judicial review is available in the U.S. Courts of Appeals.

The registrant facing this proceeding is across the table from DEA trial attorneys who have litigated these hearings many times. Dhairya Jani litigated them from that side, building the evidentiary records, examining the witnesses, and arguing the cases. He knows exactly how these proceedings are run and where they can be challenged.
