Questão jurídica principal
Whether the appeal remained admissible despite the lack of current and practical interest after no disciplinary sanction was imposed.
Decisão extraída
The appellant did not show a current and practical interest, and the exception to mootness was not demonstrated; the appeal was therefore inadmissible.
Fundamentação extraída
The challenged disciplinary opening lost practical significance when the prison renounced any sanction. The appellant did not establish a denial of justice or show that the matter satisfied the exception for issues capable of repetition yet evading review.
