Questão jurídica principal
Whether the cantonal court violated the right to be heard or committed arbitrariness by refusing to supplement the file and by not granting another extension for the appeal brief.
Decisão extraída
No. The refusal was constitutionally unobjectionable because the requested file items were not shown to be relevant and the appellant waited until the last day of the repeatedly extended deadline.
Fundamentação extraída
The appellant had long had access to the file, had already received several extensions, and did not substantiate why the missing items were necessary to challenge the cost order.
