APA Section 23 — Parties and representation
Administrative Procedure Act (พระราชบัญญัติวิธีปฏิบัติราชการทางปกครอง) — Section 23.
Plain-English Summary
A party attending before an official may bring a lawyer or adviser, and what they do in the party's presence counts as the party's act unless the party objects at once (Section 23). A party may appoint an adult in writing to act for them (Section 24). Where more than fifty persons sign a joint request or file requests of the same or similar content, a named person acts as joint representative; if none is named, the official appoints the person the majority approve (Section 25). The joint representative must be an individual.
