Key legal question
Whether the federal criminal appeal had to be struck off after the appellant's withdrawal
Extracted holding
The appellant's written request was treated as a valid and definitive withdrawal of the appeal, so the federal proceedings were discontinued without merits review.
Extracted reasoning
A party represented by counsel may still file personal submissions. The appellant clearly expressed the wish to end the proceedings without substantive examination; no lack of understanding or impaired will was shown. A voluntary withdrawal made with awareness of its procedural effect is final.
