The article aims to present a situation when a party in an administrative proceeding cannot act through an attorney-in-fact, or in other words, the party must act in person despite the appointment of an attorney-in-fact. The requirement of a party to act personally in an administrative proceeding may be the result of legal provisions, the nature of the procedural action and the content of the public administration authority's demand. These cases are exceptions to the principle that a party may act through an attorney-in-fact and are therefore subject to a strict literal interpretation.
