What Makes Federal Court Different?

Federal cases involve higher stakes and deeper investigations than most state-level charges. Federal jurisdiction applies when crimes cross state lines, occur on federal property or involve the use of federal mail, wire systems or banking institutions.

Agencies such as the FBI, DEA, IRS-CI, Secret Service, Department of Homeland Security and Defense Criminal Investigative Service (DCIS) lead these investigations.

Navigating The Federal Criminal Process

Key stages include:

• Pre-indictment phase: Federal investigators may issue target letters, witness subpoenas or gather evidence before charges are filed.
• Federal grand jury: Proceedings are held in secret and are not adversarial. Having a federal grand jury defense lawyer helps ensure that your rights are protected even when you are not present.
• Arraignment and pretrial release: Federal bail hearings can be strict, often involving limited release conditions and extensive supervision.
• Complex discovery: Federal prosecutors often rely on thousands of pages of digital or financial evidence, requiring detailed e-discovery review and analysis.

At Vela & Del Fierro, P.C., Attorneys at Law, we will work closely with you throughout each stage.
