There are many risks involved in running a business. Amongst these, the most important ones relate to matters governed by criminal law. It is not only about the possibility of a natural person being held criminally liable. In addition to the personal liability of the natural person, another relevant issue is the question of the negative consequences for the business entity itself. In addition to the dangers resulting from the loss of a good reputation, there may also be issues which make the day-to-day operation of the business considerably more difficult. One of these reasons is the possibility of blocking a bank account. This is an institution that can be used by an authorized entity in connection with a suspicion that an offence has been committed. It is intended to prevent the loss of the funds deposited at a bank account. Its use in practice poses many difficulties, including problems with the proper interpretation of the provisions. Therefore it is worth taking a closer look at this issue.
