Whether D.________'s appeal against the first-instance judgment was filed within the statutory 30-day period
No. The appeal was filed almost six months after notification of the motivated judgment and was therefore clearly out of time.
Under Art. 321 para. 1 CPC, the appeal must be filed within 30 days from notification of the motivated decision. The reasons were notified on 2015-01-16, whereas the appeal was only submitted on 2015-08-12.
