Whether the appeal announcement was filed within the statutory time limit
No. The announcement was late because the judgment was deemed notified on the seventh day of postal holding, and the 10-day period expired long before the filing date.
Under the CPP, the appeal period runs from notification of the written dispositive; uncollected registered mail is deemed notified after seven days when the addressee expected delivery. The notice sent on 13 September 2013 was therefore out of time.
