Attorney Anton Vialtsin

San Diego Federal Criminal Defense Attorney Anton Vialtsin, Esq., E.I., handled over 400 federal criminal cases in San Diego (Southern District of California) from initial client interviews through sentencing. These cases required an in-depth knowledge of the Federal Sentencing Guidelines and the Federal Criminal Codes and Rules.

Many dozens of the San Diego federal cases he managed involved individuals charged with the importation and distribution of controlled substances, all punishable by ten-year minimum mandatory sentence.

Considering that the Southern District of California located in San Diego is a border district and one of the busiest in the country, San Diego Federal Criminal Defense Attorney Anton Vialtsin defended many individuals charged with transportation and harboring of illegal aliens, misuse of a passport, and illegal entry into the United States. Further, he worked on several transportation-of-illegal-aliens cases where the transportation resulted in death, triggering the possibility of the death penalty. These cases required negotiation with AUSAs (U.S. Attorney’s Office, Southern District of California) and hours of witness depositions and interviews.

Additionally, he worked on a number of cases involving individuals charged with complex wire and mail fraud violations, aggravated identity theft, and theft of public property.

-Facing Federal Criminal Prosecution by the United States Government?

San Diego Federal Criminal Defense Attorneys at LAWSTACHE LAW FIRM handle federal and state criminal cases in all counties and districts of California and Nevada. San Diego Federal Criminal Defense Attorney Anton Vialtsin possesses the knowledge and experience to handle the full spectrum of federal criminal charges, from misdemeanors to capital murder cases.

San Diego Federal Criminal Defense Attorneys at LAWSTACHE LAW FIRM routinely represent clients facing federal criminal charges. The basic difference between federal and state criminal offenses is that a federal offense violates federal law, and a state offense violates state law. In some cases, however, federal and state laws cover the same area of criminal law. If state law contradicts federal law, federal law generally trumps state law in the interest of the national welfare. In other areas of criminal law, the federal government has exclusive power to regulate, enforce, and prosecute alleged crimes. The federal government has exclusive power to prosecute crimes involving interstate commerce, national security, and federal programs. For example, most white-collar crimes, such as credit card fraud, tax evasion, and welfare fraud, are prosecuted in federal courts.

The federal government vested much power in Federal judges compared to the California State Courts. In the federal system, the sentencing guidelines estimate the amount of prison time an individual will likely do for a crime. These guidelines are only advisory, not mandatory. This means that a judge does not have to follow the sentencing guidelines. Aside from trial and/or plea negotiations, the sentencing hearing often becomes crucial in the defendant’s life.
