"The Policy Brief covers pathways for reform of government regulation or public policy with respect to areas applicable to platform workers. These include: a) Laws and statutes enacted by the legislative branch or Congress; and b) Administrative issuances made by the executive branch [...] Further, it must be noted that judicial decisions promulgated by the Supreme Court also form part of the Philippine legal system. Indeed, numerous judicial decisions clarify rights pertaining to labour. Foremost in these decisions are the elements in determining the existence of employment relationship, more commonly known today as the four-fold test, which was first enunciated in the Supreme Court decision of Viaña v. Al-Lagadan in 1956. For the purposes of this Policy Brief, these doctrines will be considered as governing law or of what constitutes the present policy and legal landscape from which gaps may be identified. However, possible changes in the doctrines promulgated by the Supreme Court are excluded from the coverage for being judicial, and not political in nature. Thus, the Policy Brief includes proposals that can be adopted either through a legislative act or an executive or administrative issuance, taking into consideration the nuances of the breadth of legislative processes and the limits of executive rulemaking as merely directed to an existing law’s implementation."
