Can a person who has received criminal punishment (bail pending trial) engage in the profession of lawyer?

Bail pending trial is not a criminal punishment, but only after the judgment is made and the criminal responsibility is confirmed.

A person who has received criminal punishment shall not engage in judicial work, including the profession of lawyer, for life. In theory, you can participate in the selection of certain civil service positions, but in practice, people with such records, no matter how high your test scores, will eventually be eliminated and unable to be selected.
