Teacher Employment Classification Dispute: Public vs. Private Service Jurisdiction

The case concerns a music teacher whose employment contract with a municipal music school was not renewed, leading the teacher to sue for wages under private employment law, but the lower court declined jurisdiction, ruling the relationship was public service. The appellate court upheld the lower court's decision, reasoning that the public service nature of the employment was the norm under municipal personnel regulations, which stipulated private law contracts only as an exception, and the teacher failed to demonstrate specific contractual elements or clear intent establishing a private relationship, despite arguments regarding salary structure and social security contributions; furthermore, the court found no violation of the right to be heard and confirmed that executing a public mandate, even without formal election, supported the classification as a public service relationship, thus affirming the labor court's lack of jurisdiction.
