Can legal workers represent criminal cases?

1, there are two mistakes in your question: lawyers are called agents ad litem in civil cases and generally act as defendants' defenders in criminal cases. Of course, there is also a criminal incidental civil action in criminal cases, and lawyers can also act as agents in criminal incidental civil actions.

2. A lawyer refers to a person who has passed the national judicial examination and obtained a lawyer's practice certificate, but the legal workers in the legal service office do not meet the above conditions. Finally, legal workers can represent civil litigation and criminal incidental civil litigation cases, but they cannot act as defenders of defendants in criminal cases, that is, they cannot appear in court to defend defendants.
