Key legal question
Whether the definitive disciplinary exclusion from public school was compatible with the constitutional right to free compulsory education and proportionality.
Extracted holding
The definitive exclusion was not justified; a less severe solution, especially continued schooling in an appropriate public institution, would have sufficed.
Extracted reasoning
The misconduct was serious, but it was an isolated incident and did not show that lesser disciplinary measures or a temporary exclusion would have been insufficient. Under Art. 19 and 62 BV, compulsory schooling must continue in an adequate public educational setting whenever possible; definitive exclusion is only ultima ratio.
