To begin the approach to this topic, it is worth keeping in mind the provisions of chapter I of our Constitution, whose title is "Bases of institutionality", which in Article 1, paragraph 4, establishes "The State is at the service of the person human..." This has motivated the theory at the doctrinal level called public service, that as a service that has a provider (State) and a beneficiary (individuals), there are reciprocal rights and obligations and as a characteristic it must be provided with quality, which has caused more than one controversy, but it is gaining strength in both areas.
