The Southern District of California at a Glance
The United States District Court for the Southern District of California is one of four federal trial courts in California. It covers the southwestern corner of the state — San Diego and Imperial counties, along the U.S.–Mexico border — and it holds court in San Diego and El Centro.
Federal criminal cases in the district are prosecuted by the United States Attorney’s Office for the Southern District of California, which represents the government in every federal prosecution brought in this district. The court sits within the Ninth Circuit, so appeals from convictions in the Southern District of California are heard by the U.S. Court of Appeals for the Ninth Circuit.
As a major border district, the Southern District of California carries one of the heaviest federal criminal caseloads in the country. Like every federal district court, it operates under the Federal Rules of Criminal Procedure, supplemented by its own local rules governing the practical details of litigating a case there.
Federal Criminal Cases in the District
The Southern District of California handles the full range of federal criminal matters — white-collar offenses and fraud, drug and firearms cases, and other federal prosecutions. A federal case in the district generally moves through a recognizable sequence.
Most cases begin with an investigation by a federal agency, sometimes signaled by a target letter or a grand jury subpoena. Formal charges follow, typically by indictment. After an initial appearance and arraignment, the case proceeds through pretrial litigation and discovery, and is then resolved either by a negotiated plea agreement or by trial. A conviction is followed by sentencing under the federal framework. The firm’s federal criminal process hub walks through each stage in detail.
Throughout that sequence, the firm defends clients across the offense types the district sees — building the factual and legal record, litigating pretrial motions, negotiating where a negotiated resolution serves the client, and trying cases where trial is the right course.
Applied Insight: The earliest stage of a federal case is often the most important. Decisions made during an investigation — before any charge is filed — can shape everything that follows. Anyone who learns they are under federal investigation in the Southern District of California should treat that as the moment to seek counsel, not wait for an indictment.
A Border Docket and the Fast-Track Program
The Southern District of California runs one of the largest federal criminal dockets in the country, and its character is shaped almost entirely by the U.S.–Mexico border. In fiscal year 2024, the U.S. Sentencing Commission reported 2,634 individuals sentenced here — several times the volume of California’s other federal districts. Two categories make up roughly 83 percent of that docket: drug trafficking at about 42 percent and immigration offenses at about 41 percent, the bulk of it flowing through the San Ysidro and Otay Mesa ports of entry, among the busiest land crossings in the Western Hemisphere. White-collar fraud, by contrast, is a small share of the work — the inverse of the Los Angeles and Bay Area districts to the north.
The single most important sentencing feature of this district is its fast-track program. Under U.S.S.G. § 5K3.1, the government may move for a sentence reduction in eligible border cases through an early-disposition program — and in the Southern District, fast-track accounted for roughly 54 percent of all sentencings in FY2024, by far the highest rate in the country. For many defendants charged with illegal reentry or border drug offenses, the central questions are eligibility for fast-track, the size of the agreed reduction, and whether a better outcome is available outside the program. These are federal drug and immigration questions that turn on the specific charge, criminal history, and the terms the U.S. Attorney’s Office is offering at a given time.
The Bench, the U.S. Attorney, and Firearms Law
The Southern District of California has 13 authorized district judgeships under 28 U.S.C. § 133, sitting in San Diego with a divisional courthouse in El Centro for Imperial County. As of mid-2026, the chief district judge is Cynthia A. Bashant and the presiding magistrate judge is Jill L. Burkhardt. Because of its border caseload, this is among the busiest district courts in the federal system, and its judges — with the magistrate judges carrying an unusually heavy share of the initial-appearance and detention docket — manage high-volume criminal calendars with practices geared to that reality. Federal prosecutions are brought by the United States Attorney’s Office for the Southern District of California; as of mid-2026 the office is led by Adam Gordon, a career prosecutor known for fentanyl enforcement who is not a Senate-confirmed U.S. Attorney but a court-appointed one — the district’s judges appointed him under 28 U.S.C. § 546 in the summer of 2025, and career Assistant U.S. Attorneys handle its narcotics, immigration, and money-laundering caseloads. (Roster details are stated as of mid-2026; the court’s website controls the current bench.)
Firearms charges arise regularly alongside the district’s drug and border cases, and the governing law comes from the Ninth Circuit. In United States v. Duarte, 137 F.4th 743 (9th Cir. 2025), the en banc court held that 18 U.S.C. § 922(g)(1), the felon-in-possession statute, is not unconstitutional as applied to non-violent felons; the Supreme Court declined review in January 2026. A related but distinct question reached the Supreme Court in United States v. Hemani, 608 U.S. ___ (2026), where the Court held that prosecuting an unlawful drug user under 18 U.S.C. § 922(g)(3) violated the Second Amendment as applied to that defendant — a ruling the Court called narrow, aimed only at the drug-user provision and leaving the felon-in-possession rule of Duarte untouched. That distinction matters in a border district where drug and firearm charges frequently travel together. Second Amendment challenges to firearm statutes remain an active and shifting area after New York State Rifle & Pistol Ass’n v. Bruen, 597 U.S. 1 (2022), and United States v. Rahimi, 602 U.S. 680 (2024), and they should be evaluated case by case. Where a prior conviction is used to enhance a sentence under the Armed Career Criminal Act, Erlinger v. United States, 602 U.S. 821 (2024), now requires a jury — not the judge — to find that the predicate offenses occurred on different occasions.
Appeals and Post-Conviction Matters
A case in the Southern District of California does not necessarily end at sentencing. A person convicted in the district has the right to appeal to the Ninth Circuit, and the notice of appeal in a criminal case generally must be filed within fourteen days of the entry of judgment.
Beyond a direct appeal, post-conviction relief is filed in the district of conviction — so a motion under 28 U.S.C. § 2255 challenging a Southern District of California conviction is filed in that district itself. The firm also handles compassionate release and other post-conviction matters in the district. Appellate and post-conviction work is the firm’s core strength, and it travels well: because federal law is national, this work can be handled effectively in the Southern District of California regardless of where the firm is based.
How the Firm Practices in This Court
Elizabeth Franklin-Best, P.C. represents federal defendants in the U.S. District Court for the Southern District of California through admission pro hac vice. Pro hac vice — meaning, roughly, “for this occasion” — is the long-established procedure by which a qualified attorney who is not a member of a particular district court’s bar is admitted to appear in a specific case before that court.
This is a routine and well-recognized part of federal practice. Federal criminal law is national, the Federal Rules of Criminal Procedure apply in every district, and experienced federal practitioners regularly appear across district lines through pro hac vice admission. The Southern District of California, like every federal district court, has a local-rule procedure for it.
What matters most in choosing federal counsel is not a local address but genuine federal experience — particularly in the appellate and post-conviction work that is our firm’s focus. Our principal attorney, Elizabeth Franklin-Best, has handled more than 330 federal proceedings — over 100 of them appeals — and is admitted before all twelve federal courts of appeals and the U.S. Supreme Court; she is admitted to the Ninth Circuit and handles federal trial-level defense, appeals, and post-conviction matters for clients in the Southern District of California. Author of Reversing Your Criminal Conviction, she keeps a nationwide post-conviction practice and appears pro hac vice from Montana to Florida. That focus carries weight in a high-volume border district, where the difference between a fast-track plea and a litigated outcome, and between a sound and a flawed sentencing record, can be decisive on appeal. The Ninth Circuit, which granted compassionate-release motions at roughly 31 percent in fiscal year 2025 — the highest rate of any circuit — also gives post-conviction work here real room to operate.

What is the fast-track program in the Southern District of California?
Fast-track, authorized by U.S.S.G. Section 5K3.1, is an early-disposition program in which the government may move for a reduced sentence in eligible border cases, typically illegal-reentry and certain drug offenses, in exchange for an early guilty plea and a waiver of certain rights. The Southern District uses it more than any district in the country, with fast-track accounting for roughly 54 percent of sentencings in fiscal year 2024. Eligibility and the size of the reduction depend on the charge, criminal history, and the terms the U.S. Attorney’s Office is offering.
What types of cases are most common in the Southern District of California?
Because the district sits on the U.S.-Mexico border, drug trafficking and immigration offenses dominate, together making up roughly 83 percent of the district’s sentencings in fiscal year 2024. Most of that activity flows through the San Ysidro and Otay Mesa ports of entry. White-collar and fraud cases make up a much smaller share than in the Los Angeles or San Francisco Bay Area districts.
Can a felon-in-possession charge be challenged in the Southern District of California?
It can be raised, but the current Ninth Circuit rule makes it difficult. In United States v. Duarte, the en banc Ninth Circuit held in 2025 that the federal felon-in-possession statute is not unconstitutional as applied to non-violent felons, and the Supreme Court declined to review that decision in January 2026. Second Amendment challenges after Bruen and Rahimi remain an evolving area, so each case should be assessed individually, but the statute is being enforced across the circuit, including in this district.
