Questão jurídica principal
Whether the cantonal court arbitrarily found that the bank had not been duly summoned before enforcement proceedings.
Decisão extraída
Yes. The summons had in fact been served, so refusing to examine enforcement on that basis was arbitrary.
Fundamentação extraída
The summons was pleaded and evidenced in the record; the lower court overlooked a proven fact. This vitiated both the reasoning and the result.
