This document discusses teachers as persons in authority under Philippine law. It begins by defining a person in authority as someone directly vested with jurisdiction under the Revised Penal Code. Originally, teachers were not considered persons in authority. However, Commonwealth Act 578 amended the law to include teachers due to assaults against them. Now teachers have protection as persons in authority, though this does not apply when they are outside of classroom duties. The document also discusses the legal bases for teachers' security of tenure under the Philippine Constitution.
