PERSON IN AUTHORITY – any person directly vested with jurisdiction, whether as an
individual or as a member of some court or governmental corporation, board or commission.
They include:
a. Barangay captain
b. Barangay chairman

For the purposes of Art. 148 and 151:
a. Teachers
b. Professors
c. Persons charged with the supervision of public or duly recognized private schools,
   colleges and universities
d. Lawyers in the actual performance of their professional duties or on the occasion
   of such performance

and the protection and security of life and property. They include:
a. Barrio councilman

Section 388 of the Local Gov’t. Code provides that for purposes of the RPC, the
punong barangay, sangguniang barangay members and members of the lupong tagapamayapa
in each barangay shall be deemed as persons in authority in their jurisdictions.

Other barangay officials and members who may be designated by law or ordinance
and charged with the maintenance of public order, protection and the security of
life, property, or the maintenance of a desirable and balanced environment, and
any barangay member who comes to the aid of persons in authority shall be deemed agent of persons in authority.

It seems that teachers, professors, lawyers etc could be considered as persons in
authority not only for Arts. 148 and 151 but also for Art 149 (L.B. Reyes)
