Questão jurídica principal
Whether the appeal court had to sit as a single judge or in a three-judge panel in this summary-procedure enforcement appeal.
Decisão extraída
The chamber had to sit collegially; the statute did not clearly establish single-judge competence for such appeals.
Fundamentação extraída
The general rule is collegiate decision-making by cantonal appellate courts. Art. 43 al. 1 let. e CDPJ is to be interpreted restrictively and concerns first-instance courts applying summary procedure, not appellate or recourse proceedings decided under the CPC.
